Invasion biologists often suggest that phenotypic plasticity plays an important role in successful plant invasions. Assuming that plasticity enhances ecological niche breadth and therefore confers a fitness advantage, recent studies have posed two main hypotheses: (1) invasive species are more plastic than non-invasive or native ones; (2) populations in the introduced range of an invasive species have evolved greater plasticity than populations in the native range. These two hypotheses largely reflect the disparate interests of ecologists and evolutionary (...) biologists. Because these sciences are typically interested in different temporal and spatial scales, we describe what is required to assess phenotypic plasticity at different levels. We explore the inevitable tradeoffs of experiments conducted at the genotype vs. species level, outline components of experimental design required to identify plasticity at different levels, and review some examples from the recent literature. Moreover, we suggest that a successful invader may benefit from plasticity as either (1) a Jack-of-all-trades, better able to maintain fitness in unfavourable environments; (2) a Master-of-some, better able to increase fitness in favourable environments; or (3) a Jack-and-master that combines some level of both abilities. This new framework can be applied when testing both ecological or evolutionary oriented hypotheses, and therefore promises to bridge the gap between the two perspectives. (shrink)

There are long-standing doubts about whether data from subjective scales—for instance, self-reports of happiness—are cardinally comparable. It is unclear how to assess whether these doubts are justified without first addressing two unresolved theoretical questions: how do people interpret subjective scales? Which assumptions are required for cardinal comparability? This paper offers answers to both. It proposes an explanation for scale interpretation derived from philosophy of language and game theory. In short: conversation is a cooperative endeavour governed by various maxims (Grice 1989); (...) because subjective scales are vague and individuals want to make themselves understood, scale interpretation is a search for a focal point (Schelling 1960). A specific focal point it hypothesised; if this hypothesis is correct, subjective data will be cardinally comparable. Four individually necessary and jointly sufficient conditions for cardinal comparability are specified. The paper then argues this hypothesis can be empirically be tested, makes an initial attempt to do so using subjective well-being data, and concludes it is supported. Numerous areas for further research are identified including, at the end of the paper, how certain tests could be used to ‘correct’ subjective data if they are not cardinal. (shrink)

While life satisfaction theories (LSTs) of well-being are barely discussed in philosophy, they are popular among social scientists and wider society. When philosophers have discussed LSTs, they are taken to be a distinct alternative to the three canonical accounts of well-being—hedonism, desire theories, the objective list. This essay makes three main claims. First, on closer inspection, LSTs are indistinguishable from a type of desire theory—the global desire theory. Second, the life satisfaction/global desire theories are the only subjectivist accounts of well-being (...) in the sense that they maintain individuals decide what makes their lives go well for them; hedonism and other desire theories are subjectivist only in some alternative senses. Third, subjectivism is implausible, although for different reasons from those that are usually given. I examine what I take to be the two main current objections to LSTs and argue that they are unproblematic. I then raise two different, challenging objections. The first is novel. The second has been noted in passing, but its seriousness underestimated. I close by sketching some non-obvious difficulties that subjectivists will face if they attempt to show rival objectivist theories suffer even more counterintuitive implications. Although subjectivism has a strong intuitive pull, we should be ready to abandon it in favour of an objectivist theory—although it is not my purpose here to say which one. (shrink)

Suppose you want to do as much good as possible. What should you do? According to members of the effective altruism movement—which has produced much of the thinking on this issue and counts several moral philosophers as its key protagonists—we should prioritise among the world’s problems by assessing their scale, solvability, and neglectedness. Once we’ve done this, the three top priorities, not necessarily in this order, are (1) aiding the world’s poorest people by providing life-saving medical treatments or alleviating poverty (...) itself, (2) preventing global catastrophic risks, such as those posed by nuclear war or rogue artificial intelligence, and (3) ending factory farming. These claims are both plausible and striking. If correct, they should prompt a stark revision of how we approach our altruistic activities. However, the project of determining how to do the most good—as opposed to say, whether we should do the most good—has only recently, within the last ten years, become the subject of serious academic attention. Many key claims have not yet been carefully scrutinised. This is a cause for concern: are effective altruists doing good badly? In this thesis, I critique and develop some of the latest claims about how individuals can do the most good. I do this in three areas: the value of saving lives (preventing premature deaths), how best to improve lives (making people happier during their lives), and cause prioritisation methodology (frameworks for determining which problems are the highest priorities). In each case, I raise novel theoretical considerations that, when incorporated, change the analysis. Roughly speaking, my main conclusions are (1) saving lives is not as straightforwardly good we tend to suppose, may not be good at all, and is not clearly a priority; (2) happiness can be measured through self-reports and, based on the self-reported evidence, treating mental health stands out as an overlooked problem that may be an even more cost-effective way to improve lives than alleviating poverty; (3) the cause prioritisation methodology proposed by effective altruists needs to be moderately reconceptualised and, when it is, it turns out it is not as illuminating a tool as we might have thought and hoped.

As well as disagreeing about how much one should donate to charity, moral theories also disagree about where one should donate. In light of this disagreement, how should the morally uncertain philanthropist allocate her donations? In many cases, one intuitively attractive option is for the philanthropist to split her donations across all of the charities that are recommended by moral views in which she has positive credence, with each charity’s share being proportional to her credence in the moral theories that (...) recommend that particular charity. Despite the fact that something like this approach is already being used by real-world philanthropists to distribute billions of dollars of donations, it is not supported by any of the approaches to moral uncertainty that have been proposed thus-far in the philosophical literature. In this paper, we will develop a bargaining-based approach to moral uncertainty that honors the proportionality intuition in favor of splitting one’s donations. We also show how this bargaining-based approach has several further advantages over the best alternative proposals. (shrink)

Allelopathy is an important biological phenomenon in exotic plant invasions. Studies about this phenomenon can help us to understand how plant interactions influence plant colony and ecosystem functioning. Both alligator weed (Alternanthera philoxeroides, Ap) and crofton weed (Eupatorium adenophorum, Ea) are important destructive exotic species in China. Their allelopathic effects on native plant species are well documented. However, whether alligator weed and crofton weed antagonize each other regarding plant growth? There is largely unknown currently. Here we report that the leaf (...) extract from crofton weed possesses the negative effect on the growth of alligator weed. The results showed that root growth of alligator weed could be seriously inhibited by aqueous extract from crofton weed, exhibited as no root or a few roots if only. Consistent with the inhibition of root growth, we observed changes of physiological and biochemical parameters in treated alligator weed. The chlorophyll content, the root activity and the acetolactate synthase (ALS) activity were significantly decreased; while the rate of superoxide anion (O2-), the malondialdehyde (MDA) content, the peroxidase (POD) activity, and the shikimic acid content were remarkably increased in the treated alligator weed plants. These physiological analyzes suggested that the main allelopathic effects of crofton weed were mainly through affecting the integrity of cell membrane and the activity of the key enzymes. Further, these data also imply that one exotic species has the potential value to be used in bio-control of the other exotic species. (shrink)

In view of the philosophical problems that vex the debate on situated affectivity, it can seem wise to focus on simple cases. Accordingly, theorists often single out scenarios in which an individual employs a device in order to enhance their emotional experience, or to achieve new kinds of experience altogether, such as playing an instrument, going to the movies or sporting a fancy handbag. I argue that this narrow focus on cases that fit a ‘user/resource model’ tends to channel attention (...) away from more complex and also more problematic instances of situated affectivity. Among these are scenarios in which a social domain draws individuals into certain modes of affective interaction, often by way of attunement and habituation to affective styles and interaction patterns that are normative in the domain in question. This can lead to a phenomenon that is not so much ‘mind extension’ than ‘mind invasion’: affectivity is dynamically framed and modulated from without, often contrary to the prior orientations of the individuals in question. As an example, I discuss affective patterns prevalent in today’s corporate workplace. I claim that workplace affect sometimes contributes to what is effectively a ‘hack’ of employees’ subjectivity.

Some critics of invasion biology have argued the invasion of ecosystems by nonindigenous species can create more valuable ecosystems. They consider invaded communities as more valuable because they potentially produce more ecosystem services. To establish that the introduction of nonindigenous species creates more valuable ecosystems, they defend that value is provisioned by ecosystem services. These services are derived from ecosystem productivity, the production and cycling of resources. Ecosystem productivity is a result of biodiversity, which is understood as local species richness. (...) Invasive species increase local species richness and, therefore, increase the conservation value of local ecosystems. These views are disseminating to the public via a series of popular science books. Conservationists must respond to these views, and I outline a method of rejecting such arguments against controlling invasive species. Ecological systems are valuable for more than local productivity and biodiversity is not accurately described by a local species count. (shrink)

The problem of plant individuality is something which has vexed botanists throughout the ages, with fashion swinging back and forth from treating plants as communities of individuals (Darwin 1800 ; Braun and Stone 1853 ; Münch 1938 ) to treating them as organisms in their own right, and although the latter view has dominated mainstream thought most recently (Harper 1977 ; Cook 1985 ; Ariew and Lewontin 2004 ), a lively debate conducted mostly in Scandinavian journals proves that the (...) issues are far from being resolved (Tuomi and Vuorisalo 1989b ; Fagerström 1992 ; Pan and Price 2001 ). In this paper I settle the matter once and for all, by showing which elements of each side are correct. (shrink)

According to F. Adams [this journal, vol. 68, 2018] cognition cannot be realized in plants or bacteria. In his view, plants and bacteria respond to the here-and-now in a hardwired, inflexible manner, and are therefore incapable of cognitive activity. This article takes issue with the pursuit of plant cognition from the perspective of an empirically informed philosophy of plant neurobiology. As we argue, empirical evidence shows, contra Adams, that plant behavior is in many ways analogous to animal behavior. (...) This renders plants suitable to be described as cognitive agents in a non-metaphorical way. Sections two to four review the arguments offered by Adams in light of scientific evidence on plant adaptive behavior, decision-making, anticipation, as well as learning and memory. Section five introduces the ‘phyto-nervous’ system of plants. To conclude, section six resituates the quest for plant cognition into a broader approach in cognitive science, as represented by enactive and ecological schools of thought. Overall, we aim to motivate the idea that plants may be considered genuine cognitive agents. Our hope is to help propel public awareness and discussion of plant intelligence once appropriately stripped of anthropocentric preconceptions of the sort that Adams' position appears to exemplify.

Metaphors for describing the introduction, impacts, and management of non-native species are numerous and often quite outspoken. Policy-makers have adopted increasingly disputed metaphorical terms from scientific discourse. We performed a critical analysis of the use of strong metaphors in reporting scientific findings to policy-makers. Our analysis shows that perceptions of harm, invasiveness or nativeness are dynamic and inevitably display multiple narratives in science, policy or management. Improving our awareness of multiple expert and stakeholder narratives that exist in the context of (...) non-native species management, as well as metaphorical alternatives, is critical. (shrink)

All living things have sensory capacities. Plants, in particular, have sensory receptors, transduce the activations of these receptors, and process these outputs in order to manage actions that demand sensory integration. However, there is a kind of sensory function that plants cannot perform. They cannot sense something as other than themselves. Animals, by contrast, perceive. They experience two kinds of "othering impressions"—impressions of entities as located outside and available for interaction, and hence as distinct from the perceiving subject. (...) First, they represent external entities in a "body scheme" that enables sensorimotor interaction with these entities. Second, higher animals such as mammals and birds and possibly fish, represent these entities as located relative to a "cognitive map." These othering impressions are very important because they are the foundation for the human conceptions of the self and other. (shrink)

The Plant Ontology (PO; http://www.plantontology.org/) is a publicly-available, collaborative effort to develop and maintain a controlled, structured vocabulary (“ontology”) of terms to describe plant anatomy, morphology and the stages of plant development. The goals of the PO are to link (annotate) gene expression and phenotype data to plant structures and stages of plant development, using the data model adopted by the Gene Ontology. From its original design covering only rice, maize and Arabidopsis, the scope of the PO has been expanded (...) to include all green plants. The PO was the first multi-species anatomy ontology developed for the annotation of genes and phenotypes. Also, to our knowledge, it was one of the first biological ontologies that provides translations (via synonyms) in non-English languages such as Japanese and Spanish. There are about 2.2 million annotations linking PO terms to over 110,000 unique data objects representing genes or gene models, proteins, RNAs, germplasm and Quantitative Traits Loci (QTLs) from 22 plant species. In this paper, we focus on the plant anatomical entity branch of the PO, describing the organizing principles, resources available to users, and examples of how the PO is integrated into other plant genomics databases and web portals. We also provide two examples of comparative analyses, demonstrating how the ontology structure and PO-annotated data can be used to discover the patterns of expression of the LEAFY (LFY) and terpene synthase (TPS) gene homologs.

Do plants represent according to Kant? This is closely connected to the question of whether he held plants are alive, because he explains life in terms of the faculty to act on one’s own representations. He also explains life as having an immaterial principle of self-motion, and as a body’s interaction with a supersensible soul. I argue that because of the way plants move themselves, Kant is committed to their being alive, to their having a supersensible ground (...) of their self-activity, and to their having desires (although these are not conscious). This has important ramifications for Kant’s teleology and philosophy of mind. (shrink)

It is common for conservationists to refer to non-native species that have undesirable impacts on humans as “invasive”. We argue that the classification of any species as “invasive” constitutes wrongful discrimination. Moreover, we argue that its being wrong to categorize a species as invasive is perfectly compatible with it being morally permissible to kill animals—assuming that conservationists “kill equally”. It simply is not compatible with the double standard that conservationists tend to employ in their decisions about who (...) lives and who dies. (shrink)

The Plant Ontology (PO) is a community resource consisting of standardized terms, definitions, and logical relations describing plant structures and development stages, augmented by a large database of annotations from genomic and phenomic studies. This paper describes the structure of the ontology and the design principles we used in constructing PO terms for plant development stages. It also provides details of the methodology and rationale behind our revision and expansion of the PO to cover development stages for all plants, (...) particularly the land plants (bryophytes through angiosperms). As a case study to illustrate the general approach, we examine variation in gene expression across embryo development stages in Arabidopsis and maize, demonstrating how the PO can be used to compare patterns of expression across stages and in developmentally different species. Although many genes appear to be active throughout embryo development, we identified a small set of uniquely expressed genes for each stage of embryo development and also between the two species. Evaluating the different sets of genes expressed during embryo development in Arabidopsis or maize may inform future studies of the divergent developmental pathways observed in monocotyledonous versus dicotyledonous species. The PO and its annotation databasemake plant data for any species more discoverable and accessible through common formats, thus providing support for applications in plant pathology, image analysis, and comparative development and evolution.

This paper explores the ethical dimensions of lionfish removal and provides an argument supporting hunting lionfish for consumption. Lionfish are an invasive species found around the world. Their presence has fueled management strategies that predominantly rely on promoting human predation and consumption. We apply rights-based ethics, utilitarian ethics, and ecocentric environmental ethics to the question of whether hunting and eating lionfish is ethical. After applying these perspectives, we argue that, from a utilitarian perspective, lionfish should be culled. Rights-based ethics, (...) on the other hand, are not applicable in this case, while ecocentric environmental ethics would support lionfish removal. (shrink)

Plants from a handful of species provide the primary source of food for all people, yet this source is vulnerable to multiple stressors, such as disease, drought, and nutrient deficiency. With rapid population growth and climate uncertainty, the need to produce crops that can tolerate or resist plant stressors is more crucial than ever. Traditional plant breeding methods may not be sufficient to overcome this challenge, and methods such as highOthroughput sequencing and automated scoring of phenotypes can provide significant (...) new insights. Ontologies are essential tools for accessing and analysing the large quantities of data that come with these newer methods. As part of a larger project to develop ontologies that describe plant phenotypes and stresses, we are developing a plant disease extension of the Infectious Disease Ontology (IDOPlant). The IDOPlant is envisioned as a reference ontology designed to cover any plant infectious disease. In addition to novel terms for infectious diseases, IDOPlant includes terms imported from other ontologies that describe plants, pathogens, and vectors, the geographic location and ecology of diseases and hosts, and molecular functions and interactions of hosts and pathogens. To encompass this range of data, we are suggesting inOhouse ontology development complemented with reuse of terms from orthogonal ontologies developed as part of the Open Biomedical Ontologies (OBO) Foundry. The study of plant diseases provides an example of how an ontological framework can be used to model complex biological phenomena such as plant disease, and how plant infectious diseases differ from, and are similar to, infectious diseases in other organism.

This chapter develops the idea that the germ-soma split and the suppression of individual fitness differences within the corporate entity are not always essential steps in the evolution of corporate individuals. It illustrates some consequences for multilevel selection theory. It presents evidence that genetic heterogeneity may not always be a barrier to successful functioning as a higher-level individual. This chapter shows that levels-of-selection theorists are wrong to assume that the central problem in transitions is always that of minimizing within-group competition. (...) Evidence of intralevel conflict does not qualify as evidence against the existence of a higher level of selection. (shrink)

The Plant Ontology (PO) (http://www.plantontology.org) (Jaiswal et al., 2005; Avraham et al., 2008) was designed to facilitate cross-database querying and to foster consistent use of plant-specific terminology in annotation. As new data are generated from the ever-expanding list of plant genome projects, the need for a consistent, cross-taxon vocabulary has grown. To meet this need, the PO is being expanded to represent all plants. This is the first ontology designed to encompass anatomical structures as well as growth and developmental (...) stages across such a broad taxonomic range. While other ontologies such as the Gene Ontology (GO) (The Gene Ontology Consortium, 2010) or Cell Type Ontology (CL) (Bard et al., 2005) cover all living organisms, they are confined to structures at the cellular level and below. The diversity of growth forms and life histories within plants presents a challenge, but also provides unique opportunities to study developmental and evolutionary homology across organisms.

This is an article in Thomas J.J. McCloughlin (Ed.) The Nature of Science in Biology: A Resource for Educators. Graphikon Teo, Dublin. -/- Abstract: Philosophers usually tend to think of animals when they think about life, plants often only appear in their works as on the margins, in the background; they are rarely in the centre. However, plant life involves unique processes, including remarkable modes of interaction between plants and their environments. Needless to say, plants are vital (...) parts of ecosystems. Serious attention to plants provides novel and interesting perspectives on many topics in philosophy of biology, including individuality, organisation and disease. Plant biology should have a substantial part in philosophy education. To support this assertion, this paper briefly describes three topics related to plant-environment interaction and explains some of their philosophical implications. These topics are growth, plant hormones and plant-plant microbiota interactions, all of which present crucial aspects related to some prevalent topics in philosophy of biology such as individuality, systems thinking, and holobiont.

It has recently been asserted that legislative moves to consider plants as ethical subjects are philosophically foolish because plants lack autonomy. While by no means the sole basis or driving criterion for moral behavior, it is possible to directly challenge skeptical attitudes by constructing a human-plant ethics centered on fundamental notions of autonomy. Autonomous beings are agents who rule themselves, principally for their own purposes. A considerable body of evidence in the plant sciences is increasingly recognizing the capacity (...) of plants to assess, perceive, and act on their environment. The primary purpose of their doing so is to generate the conditions for their own flourishing. With these plant purposes in mind, it is evidentially inappropriate to treat plants purely as instruments. In this age of environmental crisis, knowledge of plant intelligence and autonomy opens up a new debate on respecting and promoting the well-being of the plants that make life on Earth possible.

It is clear that invasive species do have their invasion boundaries, and the boundaries are constrained by the differences between their home and alien ecosystems. However, such constraints are weakened for some particular species due to their strong adaptability. From the information-processing perspective, species, as information-processing systems, are more likely to invade the habitats (infosphere) with features compatible with their systems. Low compatibility results in poor information exchange with the new infosphere, leading to the malfunction and eventual cessation of (...) the system. Suppose the system has a large range of compatibility (strong adaptability) to maintain its information exchange with the new infosphere. In that case, it can persist, adapt, and eventually become invasive to the new infosphere, completely different from the native one. (shrink)

Le texte suivant s'appuie assez largement sur des informations scientifiques de la biologie végétale. Ce choix de philosopher à partir de la technicité et de l'historicité des objets botaniques correspond à un parti pris. La proximité de l’humain à ses objets d’étude, sa tendance à anthropomorphiser, voire anthropocentrer, les observations ou les problèmes qui se présentent à lui, a fait l’objet de multiples réflexions philosophiques et épistémologiques. Kant, pour qui « tout intérêt est finalement pratique [...] même celui de la (...) raison spéculative n’est que conditionné et n’est complet que dans l’usage pratique » 1 , Bachelard, qui appelle à « substituer à la notion anthropomorphe de cause la notion scientifique de fonction » 2 , ou Canguilhem pour qui « l’anthropocentrisme est plus aisé à rejeter que l’anthropomorphisme [...] Peut-on être biologistes sans se sentir du côté des vivants ? » 3 . Ces réflexions ne sont-elles pas toujours centrées sur les modes de connaissance ou de pensée de l’humain, alors que les « objets d’étude » en question demeurent souvent dans un certain flou, voire une large indétermination ? La démarche suivie ici tente d’aller dans une autre direction. Elle interroge les effets de l’anthropocentrisation d’objets spécifiques à la biologie végétale, envisagée aussi bien dans sa profondeur historique que dans ses développements techniques récents. Nous tentons ici un pari : une analyse précise de nos connaissances botaniques, actuelles et passées, peut nourrir la réflexion philosophique sur notre rapport aux plantes et, à travers elles, sur nous-mêmes.

Most current techniques to deal with invasive species are ineffective or have highly damaging side effects. To this end suppression-drives based on clustered regularly inter-spaced short palindromic repeats (CRISPR/Cas9) have been touted as a potential silver bullet for the problem, allowing for a highly focused, humane and cost-effective means of removing a target species from an environment. Suppression-drives come with serious risks, however, such that the precautionary principle seems to warrant us not deploying this technology. The focus of this (...) paper is on one such risk – the danger of a suppression-drive escaping containment and wiping out the target species globally. Here, I argue that in most cases this risk is significant enough to warrant not using a gene-drive. In some cases, however, we can bypass the precautionary principle by using an approach that hinges on what I term the ‘Worst-Case Clause’. This clause, in turn, provides us with a litmus test that can be fruitfully used to determine what species are viable targets for suppression-drives in the wild. Using this metric in concert with other considerations, I suggest that only three species are currently possible viable targets – the European rabbit, ship rat and Caribbean Tree Frog. (shrink)

Biodiversity loss is happening at an unprecedented rate, and invasive species are one of the main contributors to the global biodiversity decline. Invasive species are alien (non-native) organisms that become overpopulated and cause environmental harm to the native environment.

For effective biology conservation, some (...) questions are worth answering: Do invasive species have any invasion limits? Or are they capable of invading habitats significantly different from their native environment due to their strong adaptability? (shrink)

The paper attempts to conciliate the important distinction between what-is, or exists, and what-is-not _thereby supporting Russell’s existential analysis_ with some Meinongian insights.

The position that results makes it possible to rescue them back in surprising but non-threatening form, leaving our ontology safe from contradiction.

Abstract: It is the aim of this paper to establish a temporal and cultural link between entheogen-use1 in Classical mystery cults and their possible use in a segment of the early Christian Gnostic Church. As early Christianity was heavily influenced by the Classical world in which it first developed, it is essential to examine the evidence of entheogen-use within Classical mystery cults, and explore their possible influence on the development of Christian ritual. We will first present textual evidence from the (...) New Testament and Nag Hammadi Library (NHL) that indicate possible use of ritual entheogens. Next we will examine entheogen-use by some of the main religious sects of the ancient Mediterranean world as part of their liturgical practice between c. fifth century BCE and the third century CE. Then we will show that the different schools of philosophical thought examined were quite fluid, and that there was considerable overlap among schools with respect to several key philosophies and practices. Ultimately the subject of entheogen-use in the Classical world necessarily falls into the realm of plausible speculation mainly due to the lack of primary sources. However, should the entheogenic hypothesis2 prove to be correct, it promises to be quite useful in future research and in the translation of original documents. (shrink)

We know that animals are harmed in plant production. Unfortunately, though, we know very little about the scale of the problem. This matters for two reasons. First, we can’t decide how many resources to devote to the problem without a better sense of its scope. Second, this information shortage throws a wrench in arguments for veganism, since it’s always possible that a diet that contains animal products is complicit in fewer deaths than a diet that avoids them. In this paper, (...) then, we have two aims: first, we want to collect and analyze all the available information about animal death associated with plant agriculture; second, we try to show just how difficult it’s to come up with a plausible estimate of how many animals are killed by plant agriculture, and not just because of a lack of empirical information. Additionally, we show that there are significant philosophical questions associated with interpreting the available data—questions such that different answers generate dramatically different estimates of the scope of the problem. Finally, we document current trends in plant agriculture that cause little or no collateral harm to animals, trends which suggest that field animal deaths are a historically contingent problem that in future may be reduced or eliminated altogether.

Abstract: In this study, we explore the possibility of classifying the plant species. We collected the plant species from Kaggle website. This dataset encompasses 544 samples, encompassing 136 distinct plant species. Recent advancements in machine learning, particularly Artificial Neural Networks (ANNs), offer promise in enhancing plant Species classification accuracy and efficiency. This research explores plant Species classification, harnessing neural networks' power. Utilizing a rich dataset from Kaggle, containing 544 entries, we develop and evaluate a neural network model. Our neural network, (...) featuring a single hidden layer, achieves remarkable results—a staggering 100% accuracy and a minute average error rate of 0.002. Beyond performance metrics, we delve into the intricacies of plant Species classification through feature importance analysis. The most influential features— Vegsout, durflow, semiros, pdias, begflow, wind, leafy, autopoll and insects— uncover the physiological traits underpinning accurate rice classification. This research contributes to advancing rice classification methods and highlights the potential of ANNs in optimizing agricultural practices, ensuring plant safety, and bolstering global trade.

Public parks play important roles in conserving biodiversity, promoting environmental sustainability, fostering community engagement, and enhancing the overall well-being of residents in urban areas. Nevertheless, finance is needed to maintain and expand the greenspaces in the parks. The current study aims to examine how perceptions of biodiversity loss consequences and park visitation frequency influence the residents’ willingness to contribute financially to tree-planting projects in public parks. Employing the Bayesian Mindsponge Framework analytics on a dataset of 535 Vietnamese urban residents, we (...) discovered that perceived health loss and knowledge erosion as consequences of biodiversity loss and park visitation frequency are directly positively associated with financial donation willingness. Meanwhile, the perceived economic growth loss was found to be indirectly positively associated with donation willingness through park visitation frequency, whereas the perceived loss of nature-based recreation opportunities exhibits the opposite indirect association. Based on these results, communication strategies focusing on the multifaceted benefits of biodiversity preservation and investments in public parks are recommended to improve urban residents’ financial support to park panting initiatives, accessibility to greenspaces, and connections with nature. These are crucial for promoting an eco-surplus culture that enhances biodiversity conservation and human well-being. (shrink)

The view that living beings as well as plant-based medicaments possess causal properties that are caused by the causal properties of their constituents, without being reducible to the combination of the causal properties of these constituents goes back to ancient thinkers such as Alexander of Aphrodisias and Johannes Philoponus. In the early modern period, this view was not only criticized by natural philosophers taking a reductionist stance; it was also criticized by Neo-Platonic thinkers such as Jean Fernel. One of the (...) relatively few early modern natural philosophers who adopted an emergentist position was Jacob Schegk. The present article discusses whether Schegk’s analysis of the structure of plants and medicaments offers the theoretical resources required to answer Fernel’s critique of the tradition going back to Alexander. In particular, it examines whether Schegk’s account of synchronic upward causation and diachronic downward causation could offer solutions to two interrelated problems identified by Fernel: the question of whether a mere aggregates of material particles could form a composite that possesses substantiality, not only accidental unity; and the question of whether multitudes of material particles could bring forth simple forms, whose existence seems to be presupposed by powers that cannot be ascribed to the constituents.

India dropped its target of 500 GW of renewable energy capacity fossil fuel sources by 2030. Its responsibilities the United Nations Framework Convention Climate Change [UNFCCC],and reducing radiations by one billion tonnes by the end of the decade at the COP26 conference, held in Glasgow in November 2022.

The most important factor in using (...) solar energy is the location of the solar power plant. The main objective of this study is to find the best location for a new solar power plant in a specific region called Bundelkhand region of Uttar Pradesh in India. Here we offer an extension of ELECTRE III method as two-phase Pythagorean neutrosophic elimination and choice translating reality PN-ELECTRE-III) method to adapt with fuzzy, ambiguous, unsure, and indeterminate criteria. The Pythagorean neutrosophic numbers [PNNs] used by the group decision support system of PN-ELECTRE III to measure performance of the alternatives. The options are entirely outclassed in the subsequent stage in view of the past stage's evaluations of them. By defining PNN we describe the technique of indifference threshold functions, preference treshold and veto threshold functions, which provide a more stable basis to drop outranking relations. By calculating the concordance credibility, discordance credibility and net credibility degrees of each alternative, the ranking module of the PN-ELECTRE III approach is made simpler. In order to confirm the applicability of the strategy suggested in this paper, the location selection problem for solar plants is finaly solved. (shrink)

ArgumentThe sixteenth-century physician and philosopher Julius Caesar Scaliger suggests that in particular cases plants can come into being that belong to a plant species that did not exist before. At the same time, he holds that God could not have created a more perfect world. However, does the occurrence of new species not imply that the world was not the best possible world from the beginning? In this article, I explore a set of metaphysical ideas that could provide Scaliger (...) with the means of solving this problem: His version of the notion of a plurality of substantial forms in every living being, and his version of the notion of the ordained divine power. As it turns out, Scaliger analyzes the generation of new species in terms of a development of subordinate substantial forms into dominant substantial forms. Thereby, previously existing essences of plant parts become essences of plants. These plants, thus, possess essences that no previously existing plant possessed and, in this sense, belong to a new species. In this way, Scaliger avoids positing the occurrence of new essences, thus saving the best possible world thesis. Moreover, he believes that all substantial forms stand in a relationship of mutual existential dependence by means of which God safeguards the persistence and unity of the world. This is why the agency of subordinate forms turned dominant can be understood as an expression of the ordained power of God. (shrink)

In a recent study published in Scientific Reports, the researchers documented the first wild animal seen using a plant with known medicinal properties to heal a wound.

This book assembles recent research on memory and learning in plants. Organisms that share a capability to store information about experiences in the past have an actively generated background resource on which they can compare and evaluate coming experiences in order to react faster or even better. This is an essential tool for all adaptation purposes. Such memory/learning skills can be found from bacteria up to fungi, animals and plants, although until recently it had been mentioned only as (...) capabilities of higher animals. With the rise of epigenetics the context dependent marking of experiences on the genetic level is an essential perspective to understand memory and learning in organisms. -/- Plants are highly sensitive organisms that actively compete for environmental resources. They assess their surroundings, estimate how much energy they need for particular goals, and then realize the optimum variant. They take measures to control certain environmental resources. They perceive themselves and can distinguish between ‘self’ and ‘non-self’. They process and evaluate information and then modify their behavior accordingly. -/- The book will guide scientists in further investigations on these skills of plant behavior and on how plants mediate signaling processes between themselves and the environment in memory and learning processes.

This paper contains my attempt to pastiche the Lacanian philosopher and social theorist Renata Salecl. The pastiche focuses on the effects of coronavirus on liberal societies, the invasion of Ukraine, and offers a definition which I think is of interest to analytic philosophy.

methods that have shown promise for improving extreme risk analysis, particularly for assessing the risks of invasive pests and pathogens associated with international trade. We describe the legally inspired regulatory regime for banks, where these methods have been brought to bear on extreme ‘operational risks’. We argue that an ‘advocacy model’ similar to that used in the Basel II compliance regime for bank operational risks and to a lesser extent in biosecurity import risk analyses is ideal for permitting the (...) diversity of relevant evidence about invasive species to be presented and soundly evaluated. We recommend that the process be enhanced in ways that enable invasion ecology to make more explicit use of the methods found successful.. (shrink)

Humans, like other organisms, are still dependent on multiple ecosystem functions and services to sustain their livelihoods, such as the provision of food, the provision of clean water, the decomposition of waste, etc. Ironically, while the negative impacts caused by human activities are pushing many species to the verge of extinction, more and more evidence shows that biodiversity plays a crucial role in ensuring the ecosystem’s functioning and provisioning of ecosystem services.

In recent decades, philosophers and theologians have become increasingly aware of the extent of animal pain and suffering, both past and present, and of the challenge this poses to God’s goodness and justice. As a result, a great deal of effort has been devoted to the discussion and development of animal theodicies, that is, theodicies that aim to offer morally sufficient reasons for animal pain and suffering that are in fact God’s reasons. In this paper, I ask whether there is (...) a need to go even further than this, by considering whether effort should be made to extend theodicy to include plants as well. Drawing upon ideas found in some recent animal theodicies as well as in the work of some environmental ethicists, I offer three arguments for supposing that plants should indeed fall within the purview of theodicy: the argument from non-flourishing as evil, the argument from moral considerability, and the argument from intrinsic value. I also consider a possible objection to each of these arguments. Having outlined and defended the aforementioned arguments for broadening theodicy to include plants as well as humans and animals, I conclude by considering what a plant theodicy might look like.

Are plants conscious? Most knowledgeable people say they aren't. A small minority say they are. Others say we don't know. Virtually all assume the predicate '– is conscious' is fully determinate; plants are or aren't in its extension. Appealing to Mark Wilson's work on predicates and concepts, I challenge that assumption, proposing that the predicate isn't determinate for plants. I offer the start of an explanation for why this is so. We tacitly rely on many empirical correlations (...) when we correctly characterize creatures as conscious, but we have limited knowledge of those facts, and plants differ significantly from animals, while also being substantively similar to them. We don't yet know what it would be for them to be conscious. (shrink)

The Planteome project provides a suite of reference and species-specific ontologies for plants and annotations to genes and phenotypes. Ontologies serve as common standards for semantic integration of a large and growing corpus of plant genomics, phenomics and genetics data. The reference ontologies include the Plant Ontology, Plant Trait Ontology, and the Plant Experimental Conditions Ontology developed by the Planteome project, along with the Gene Ontology, Chemical Entities of Biological Interest, Phenotype and Attribute Ontology, and others. The project also (...) provides access to species-specific Crop Ontologies developed by various plant breeding and research communities from around the world. We provide integrated data on plant traits, phenotypes, and gene function and expression from 95 plant taxa, annotated with reference ontology terms. (shrink)

This contribution demonstrates that the development and growth of plants depends on the success of complex communication processes. These communication processes are primarily sign-mediated interactions and are not simply an mechanical exchange of ‘information’, as that term has come to be understood (or misunderstood) in science. Rather, such interactions as I will be describing here involve the active coordination and organisation of a great variety of different behavioural patterns — all of which must be mediated by signs. Thus proposed, (...) a biosemiotics of plant communication investigates communicationprocesses both within and among the cells, tissues, and organs of plants as sign-mediated interactions which follow (1) combinatorial (syntactic), (2) context-sensitive (pragmatic) and (3) content-specific (semantic) levels of rules. As will be seen in the cases under investigation, the context of interactionsin which a plant organism is interwoven determines the content arrangement of its response behaviour. And as exemplified by the multiply semiotic roles playedby the plant hormone auxin that I will discuss below, this means that a molecule type of identical chemical structure may function in the instantiation of differentmeanings (semantics) that are determined by the different contexts (pragmatics) in which this sign is used.
