Spotted Frog (Rana lutcivcntris) Dispersal in the Lower Lump Drainage

Abstract

Populations of amphibian species have been declining throughout the world. This factor is significant because amphibian population dynamics can be an indication of anthropogenic disturbance in the environment. The ability of adjacent populations to interact via dispersing individuals correlates with the overall resilience of a species. Landscape features coupled with varied seasonal needs are also factors that have an impact on dispersal rates. The objective of this study was to delineate dispersal patterns of Rana luteiventris with respect to temporal variations, spatial factors, individual disperser characteristics, and effects of mining effluent on dispersal. Gaining a better understanding of the patterns of dispersal in Rana luteiventris will improve awareness of the management/conservation concerns of montane anuran populations.
