| a new species of leopard frog (anura: ranidae) from the urban northeastern us. | past confusion about leopard frog (genus rana) species composition in the tri-state area of the us that includes new york (ny), new jersey (nj), and connecticut (ct) has hindered conservation and management efforts, especially where populations are declining or imperiled. we use nuclear and mitochondrial genetic data to clarify the identification and distribution of leopard frog species in this region. we focus on four problematic frog populations of uncertain species affiliation in northern nj, ... | 2012 | 22321689 |
| cryptic diversity in metropolis: confirmation of a new leopard frog species (anura: ranidae) from new york city and surrounding atlantic coast regions. | we describe a new cryptic species of leopard frog from the new york city metropolitan area and surrounding coastal regions. this species is morphologically similar to two largely parapatric eastern congeners, rana sphenocephala and r. pipiens. we primarily use bioacoustic and molecular data to characterize the new species, but also examine other lines of evidence. this discovery is unexpected in one of the largest and most densely populated urban parts of the world. it also demonstrates that new ... | 2014 | 25354068 |
