Terrestrial distribution of pond-breeding salamanders around an isolated wetland.
Terrestrial habitats surrounding isolated wetlands are a critical resource for many pond-breeding amphibian species, yet few studies have examined the terrestrial distribution of post-metamorphic juveniles and adults. We used an encircling drift fence at a breeding pond in conjunction with partial fences at 90, 172, and 332 m from the wetland to estimate the terrestrial distribution of adult ma...
متن کاملThe influence of breeding phenology on the genetic structure of four pond‐breeding salamanders
Understanding metapopulation dynamics requires knowledge about local population dynamics and movement in both space and time. Most genetic metapopulation studies use one or two study species across the same landscape to infer population dynamics; however, using multiple co-occurring species allows for testing of hypotheses related to different life history strategies. We used genetic data to st...
متن کاملAPPLIED ISSUES Interaction of an insecticide with larval density in pond-breeding salamanders (Ambystoma)
1. Amphibian populations residing in or near agricultural areas are often susceptible to pesticide contamination. Recent evidence suggests that the effects of pesticides on amphibians often exceed those estimated in laboratory toxicity tests because other environmental factors (e.g. predators, resource abundance) can influence pesticide toxicity. 2. To examine the effects of an insecticide (car...
متن کاملTwelve-Year Study Monitoring Two Species of Pond-Breeding Salamanders in Northeast Ohio
Studies suggest a worldwide decline in amphibians during the last four decades, however these studies have rarely included long-term (>10 years) studies involving interacting species of North American salamanders. In this study, populations of spotted salamanders (Ambystoma maculatum) and Jefferson Salamanders (A. jeffersonianuni) at Cuyahoga Valley National Recreation Area in northeast Ohio we...
متن کاملEnvironmental influences on egg and clutch sizes in lentic- and lotic-breeding salamanders
Environmental influences on egg and clutch sizes in lenticand lotic-breeding salamanders. Recent research indicates that social and environmental factors influence egg and clutch sizes in amphibians. However, most of this work is based on the reproductively diverse order Anura (frogs and toads), whereas less research has been conducted on Caudata (salamanders) and Gymnophiona (caecilians). Rese...
