This article aims to find the elements that are required for a common ethical approach that is suitable for the different perspectives adopted in integrative biodiversity conservation research. A general reflection on the integrity of research is a priority worldwide, with a common aim to promote good research practice. Beyond the relationship between researcher and research subject, the integrity of research is considered in a broader perspective which entails scientific integrity towards society. In research involving a variety of disciplines and (...) a diversity of legal and ethical frameworks, there is a need of harmony between different sets of values. The notion of congruence reflects the consistency of ethics in research within the biodiversity conservation’s community of researchers. It also bears on the coherence of values shared between the scientific community and society. We examine the notion of research integrity in a broad sense. This examination is to be conducted in relation to the goal of protecting ecological integrity, which is at the core of biodiversity conservation. The notion of integrity constraints should be investigated further to develop a pragmatic response to the need for integrity and congruence in research for biodiversity conservation. (shrink)
