Programs for invasive research in North American zoos and aquariums

Abstract

Zoo-based research in North America is an emerging field, which has progressed from an ad hoc approach in a small number of zoos to a coordinated, integrated network of scientists with recognized research programs in approximately one half of the accredited institutions in North America. The disciplines most active in these programs-veterinary medicine and pathology, nutrition, reproductive biology, contraception, and behavior-are now becoming coordinated in zoos through Scientific Advisory Groups. Zoos with research programs generally establish either an institutional animal care and use committee or another committee to evaluate research proposals. In addition to scientific merit and experimental design, zoos evaluate proposals based on factors such as priority by conservation program/ identified need; direct effect on species conservation, species type, and appropriateness; availability and location of animals; operational requirements/logistics; communication between institutions; and available funding. Euthanasia is considered only in rare circumstances. Zoo-based research has evolved into an integral component in animal management and conservation programs by providing practical information that is used to improve animal care, well-being, health, and reproduction. However, the degree to which zoos participate in invasive research varies considerably among institutions, due not only to resource limitations but also to how the term "invasive" is defined and accepted at each institution. A more standardized approach among zoological institutions for examining and approving research projects that are supported by zoo-based conservation programs would greatly facilitate the wildlife research efforts of North American zoos.
