APPLICATION OF PHYSIOLOGICAL CONSERVATION TO CRAYFISH CONSERVATION

Conservation of remaining crayfish biodiversity requires increased knowledge of environmental constraints and sensitivity to contaminants, how tolerance varies within and between species, and how physiology is affected by common symbionts. Differences in environmental tolerances between populations may be indicative of local adaptations helpful in delineating conservation units. Variation in degree of tolerance to environmental stress within a population may be used to predict ability to adapt to environmental change and differentiate between tolerant and at-risk populations. Presence/absence of symbionts may further increase or decrease tolerance to stressful conditions. Linkages between physiology, ecology, and conservation should be extremely fruitful but have received little attention in crayfish conservation. In this presentation, I will discuss a range of traditional and new research approaches to address these issues, and theoretical frameworks within which results can be integrated at the enzymatic, individual, population, and community levels. Theoretical frameworks range from individual thresholds to bioenergetics models to the adverse outcome pathway concept (AOP). Hopefully, these ideas and techniques will stimulate new and productive research directions for crayfish conservationists and encourage collaborative efforts between ecologists, physiologists, and conservationists.
