Amphibian Use Of Constructed Ponds On Maryland's Eastern Shore, Catherine E. Merovich, James H. Howard

Journal of the Iowa Academy of Science: JIAS

Amphibian assemblages were sampled at nine constructed ponds (three in each age category: new ponds-age <1 yr, young ponds-age 4-5 yr, old ponds-age >30 yr) on Maryland's eastern shore (May-October 1994, March-August 1995) using a total of 27 drift fence and funnel trap arrays. The importance of habitat and landscape variables including pond age was considered in explaining amphibian use and distribution across ponds. Specifically, amphibian (1) abundance; (2) composition; (3) diversity; (4) richness; and (5) reproductive success were studied. During both years, we captured 1904 individuals comprising ten species. The most frequently collected species (species found in all treatments) were Bufo fowleri, Rana sphenocephala utricularius, and Rana …
