INTEGRATIVE TAXONOMY AND CRAYFISH CONSERVATION
Effective conservation of biodiversity is highly dependent upon a robust taxonomic framework, which in turn is based on an understanding of the characteristics that define species limits. Historically, crayfish species have been delimited based on morphological variation; key taxonomic characters are assumed to differ among, but not within species. In recent years, molecular genetic data - primarily fragments of the mitochondrial genome - have become a common addition to taxonomic studies. In several of these studies, results of parallel morphological and molecular analyses have seemingly been at odds with each other. Such conflicts have been contentious, yet arise in large part from a lack of understanding of the mechanisms that underlie both morphological and molecular variation. Morphology and mitochondrial DNA are far from the only data types that can, and should, be used to aid in species delimitation. Indeed, there is a real need for an integrative approach to crayfish taxonomy in which molecular, morphological, biogeographical, behavioral, physiological, and ecological data together help define operational taxonomic units for effective conservation.
