Freshwater Invertebrates – Neglected Victims of Biological Monitoring: An Ethical View

Abstract

Invertebrates are generally excluded from ethical consideration in scientific research and in environmental protection. In this paper I present and characterize controversies related to the use of freshwater benthic invertebrates in biological monitoring in the light of diverse ethical concepts. I consider the inherent contradictions which arise from simultaneously treating wild animals as: items possessing bio-indicative value, ecologically important elements of ecosystems, representatives of rare and endangered species and finally, as sentient beings with the capacity to suffer. The analysis is based on numerical data collected during projects related to biological monitoring of Polish watercourses. Among the ethical concepts discussed, only the evolutionary inclusive one allows for a coherent classification of all animals according to the innate values assigned to individuals, and only this concept provides us with convincing arguments enabling the incorporation of individual invertebrates within the scope of ethical considerations.
