A common mesofilter approach to conservation of biological diversity and ecosystem function used in agricultural and urban landscapes is maintenance of wetlands and an undisturbed terrestrial buffer surrounding wetlands. Although it is generally accepted that forest buffers protect wetland‐associated biological diversity and ecosystem function, the effectiveness and optimal spatial extent of buffers...
Although amphibians use human-created habitats in urban landscapes, few studies have investigated the quality of these habitats. To assess habitat quality of stormwater management ponds and adjacent urban uplands for wood frogs (Lithobates sylvaticus) and American toads (Anaxyrus americanus), we compared life history characteristics between populations breeding across an urbanization gradient. Specifically,...
Territorial disputes are frequently settled by an advantage afforded to one of the contestants by asymmetries such as size difference, strength and motivation. Allegheny Mountain Dusky Salamanders (Desmognathus ochrophaeus) are reported to defend cover objects, a form of territorial behaviour. We conducted an experiment to determine whether or not adult salamanders of this species exhibit prior residence...
The distribution of wetland breeding amphibians may be influenced by multiple habitat variables interacting at various scales. We applied a multi-scaled modeling approach to relate the presence and absence of carpenter frogs (Lithobates virgatipes), a species of conservation concern in Maryland, to several wetland and landscape characteristics. We also investigated relationships between wetland habitat...
