Amphibian populations that use small isolated wetlands are often small in size, susceptible to stochastic extinction processes, and have little to no contact with other populations. One can ascertain the persistence of such populations only by obtaining data that allow the prediction of future changes in population’s size, and propensity to achieve a sustainable number of individuals. The number of metamorphosing larvae leaving a pond predicts the viability of a salamander population, and thus, the number recruited into the terrestrial adult population. The Jefferson Salamander, Ambystoma jeffersonianum, is a listed threatened species in Illinois, occurring at fewer than 15 ponds …

Little is known about the reptiles and amphibians of Kinmen Island, Taiwan. Until recently, Kinmen had been off-limits to outsiders. It wasn’t until the mid 1990’s that civilian travel was allowed to and from the island. We surveyed 8 sites from 19 May through 18 July 2005, using 15 m drift fences with collapsible funnel traps on the ends. We documented encounters with animals outside the traps and observed 258 individuals of 7 species during our survey. The herpetofauna encountered consisted of two anuran, two lizard, and three snake species. The two anuran species made up over 97% of the …
