Chapters Four and Five utilized a 5+-year mark-recapture data set on the cave-adapted crayfish Orconectes australis to explore how energy availability has shaped its evolutionary history and population dynamics. Time-to-maturity, age-at-first-reproduction, and longevity of O. australis were substantially longer than those estimated for most crayfish species, indicating evolution of a K-selected life history. Chapter Five found that biomass and secondary production of O. australis were positively related to resource availability. Energetic models indicated resource deficits were not present, but that nearly all prey production is necessary to support each O. australis population. Thus, inter- and intra-specific competition for resources within caves is likely high. Collectively, Chapters Four and Five provide the first quantitative explanation of why K-selected life histories are an evolutionary advantage to obligate cave taxa like O. australis. iii
