The present paper stems from the biosemiotic modelling of individual artificial cognition proposed by Ferreira and Caldas (2012) but goes further by introducing the concept of Umwelt Overlap. The introduction of this concept is of fundamental importance making the present model closer to natural cognition. In fact cognition can only be viewed as a purely individual phenomenon for analytical purposes. In nature it always involves the crisscrossing of the spheres of action of those sharing the same environmental bubble. Plus, the (...) incorporation of that concept is vital to understand the complex semiosis that sustains collective tissues, societies, regulating collective cognition and consequently cooperative action. The concept of Umwelt Overlap broadens the range of applicability of the previous model to several distinct domains allowing for example for its application to multi-agent cooperative autonomous systems. In this paper a Middle Size League RoboCup soccer team is used as an example of a possible application. (shrink)

In this paper I explore the value of invertebrates to human society. I initially examine various ecological, utilitarian, scientific, and cultural benefits provided by invertebrate organisms. I then explore the extent of appreciation and understanding of these values among the American public. This assessment was based on a study of residents of the state of Connecticut, including randomly selected members of the general public, farmers, conservation organization members, and scientists. The general public and farmers were found to view most invertebrates (...) with aversion, anxiety, fear, avoidance, and ignorance. Far more positive and knowledgeable attitudes toward invertebrates and their conservation were observed among scientists and, to a lesser extent, among conservation organization members. I finally examine the motivational basis for hostile attitudes toward invertebrates, particularly arthropods, among the general public. Important factors include the possibility of an innate learning disposition, the association of many invertebrates with disease and agricultural damage, differences in ecological scale between humans and invertebrates, the multiplicity of invertebrates, the apparent lack of a sense of identity and consciousness among invertebrates, the presumption of mindlessness among invertebrates, and the radical autonomy of invertebrates from human control.

The current article is the first in a series of review articles addressing biosemiotic terminology. The biosemiotic glossary project is inclusive and designed to integrate views of a representative group of members within the biosemiotic community based on a standard survey and related publications. The methodology section describes the format of the survey conducted in November–December 2013 in preparation of the current review and targeted on the terms ‘agent’ and ‘agency’. Next, I summarize denotation, synonyms and antonyms, with special emphasis (...) on the denotation of these terms in current biosemiotic usage. The survey findings include ratings of nine citations defining or making use of the two terms. I provide a summary of respondents’ own definitions and suggested term usage. Further sections address etymology, connotations, and related terms in English and other languages. A section on the notions’ mainstream meaning vs. their meaning in biosemiotics is followed by attempt at synthesis and conclusions. Although there is currently no consensus in the biosemiotic community on what constitutes a semiotic agent, i.e., an agent in the context of semiosis, most respondents agree that core attributes of an agent include goal-directedness, self-governed activity, processing of semiosis and choice of action, with these features being vital for the functioning of the living system in question. I agree that these four features are constitutive of biosemiotic agents, and stipulate that biosemiotic agents fall within three major categories, namely 1) sub-organismic biosemiotic agents, 2) organismic biosemiotic agents and 3) super-organismic biosemiotic agents.

This article provides an extract from the second half of Lestel's book Animality . His book is divided into two parts. In the first part Lestel considers a number of ways in which humans and animals have been represented, particularly with respect to their supposed differences and borderline cases, over the course of Western history. To this end one reads of various depictions, construc- tions, and erasures of animals, including those of feral children, the animal-machines of Des- cartes and company, (...) animals of ethological study, as well as artistic animals, suffering animals, speaking animals, cultural animals, and more. The first part is largely devoted, then, to past representations of animals as seen through Lestel's unique perspective. The second part, much of which is translated here, conveys Lestel's own observations, as developed most explicitly in his concept of “hybrid com- munities” between humans and animals. It is equal parts evolutionary and cultural anthropol- ogy, ethologi.. (shrink)

Several language experiments have been carried out on apes and other animals aiming to narrow down the presumed qualitative gap that separates humans from other animals. These experiments, however, have been driven by the understanding of language as a purely symbolic sign system, often connected to a profound disinterest for language use in real situations and a propensity to perceive grammatical and syntactic information as the only fundamental aspects of human language. For these reasons, the language taught to apes tends (...) to discard iconic and indexical elements in favour of symbolic signs. This paper sheds light on the iconic components of human language, with close attention to the iconic properties of language as present in the ape language experiments. We emphasise the role of the body in the interpretation and production of iconic signs, while demonstrating the need to take into account the Umwelt theory in the research paradigm of the experiments. Uexküll’s Umwelt theory is used to exemplify the methodological problems connected to the teaching of human language to other animal species; furthermore, we discuss how the modelling capacities of language affect the biological layer that constitutes the animal Umwelt. Language is analysed as a particular case of Umwelt transition, and as such its implications are further discussed in the article. With this paper, we enrich the discussion surrounding the human-ape pidgin language by advocating for the need to include iconic components as vital parts of this research area. With this inclusion, we uncover the inter-dependency of iconic, indexical and symbolic signs in human language, aiming to further develop the research paradigm of the ape language experiments.

Communication and behaviour of animals living ex situ has been one of the major sources of knowledge about wild animals. Nevertheless, it is also acknowledged that depending on the environment that the animals inhabit, there are differences in their communication and behaviour. With some species it is difficult to reproduce their natural environment to an extent that excludes deviations from the behaviour and communication exhibited by animals living in situ. In zoological gardens, welfare measures are introduced in order to counteract (...) the effects of the captive environment and to grant an individual’s good physical and psychological well-being. The relation between good welfare and species-specific communication and behaviour is discussed, and as a result, a general model of ex situ animal communication and behaviour is proposed. The suggested model is inclusive of differences between captive animals and free-ranging animals and serves to explain the welfare-related reasons underlying individual animal’s deviations from species-specific behaviour and communication.

This paper analyses the cultural and biosemiotic bases of human attitudes towards other species. A critical stance is taken towards species neutrality and it is shown that human attitudes towards different animal species differ depending on the psychological dispositions of the people, biosemiotic conditions (e.g. umwelt stuctures), cultural connotations and symbolic meanings. In real-life environments, such as zoological gardens, both biosemiotic and cultural aspects influence which animals are chosen for display, as well as the various ways in which they are (...) displayed and interpreted. These semiotic dispositions are further used as motifs in staging, personifying or de-personifying animals in order to modify visitors’ perceptions and attitudes. As a case study, the contrasting interpretations of culling a giraffe at the Copenhagen zoo are discussed. The communicative encounters and shifting per ceptions are mapped on the scales of welfaristic, conservational, dominionistic, and utilitarian approaches. The methodological approach described in this article integrates static and dynamical views by proposing to analyse the semiotic potential of animals and the dynamics of communicative interactions in combination.
