摘要: Understanding the behavior of species threatened with extinction is important for conservation planning and solving problems facing in captivity wild. We examined diurnal activity budgets habitat use extinct wild Kihansi spray toad to provide insights into ongoing initiatives this species. Observations on eight target behaviors were made each morning evening 14 days, two subpopulations at University Dar es Salaam captive breeding centers. There significantly more bouts resting than calling, amplexing, hunting, walking, climbing, or feeding. was no difference mean time spent between subpopulations. The variable age classes, sampling time. Young toads top vegetation walls while adults rested logs. Further, foraged ground evening. Contrastingly, young switched elevated patches during similarity toads' suggests that biological traits are still maintained retained across generations. Furthermore, temporal spatial variations structures groups suggest fine-scale resource partitioning reduce competition gregarious These results highlight importance maintaining diverse useful reintroduction future restocking programs.
