Annual variation in temporal and spatial patterns of amphibian migration and dispersal are poorly understood. To address this issue, a circular drift fence was installed around an ephemeral pond at the Central Kentucky Wildlife Management Area, Madison County, Kentucky. The pond was checked daily for salamander movements from 17 January 2010 to 26 September 2010 and from 26 January 2011 to 3 August 2011, which corresponded to the activity season. Weather variables examined in relation to amphibian movements included barometric pressure, cumulative precipitation, temperature and relative humidity. Several species used the ephemeral pond during the study but few successfully reproduced. …
