| environmental gradients in old-growth appalachian forest predict fine-scale distribution, co-occurrence, and density of woodland salamanders. | woodland salamanders are among the most abundant vertebrate animals in temperate deciduous forests of eastern north america. because of their abundance, woodland salamanders are responsible for the transformation of nutrients and translocation of energy between highly disparate levels of trophic organization: detrital food webs and high-order predators. however, the spatial extent of woodland salamanders' role in the ecosystem is likely contingent upon the distribution of their biomass throughou ... | 2018 | 30619595 |
| multilocus phylogeography and species delimitation in the cumberland plateau salamander, plethodon kentucki: incongruence among data sets and methods. | species are a fundamental unit of biodiversity, yet can be challenging to delimit objectively. this is particularly true of species complexes characterized by high levels of population genetic structure, hybridization between genetic groups, isolation by distance, and limited phenotypic variation. previous work on the cumberland plateau salamander, plethodon kentucki, suggested that it might constitute a species complex despite occupying a relatively small geographic range. to examine this hypot ... | 2016 | 26974148 |
| territorial behavior of the plethodontid salamander plethodon kentucki: influence of habitat structure and population density. | to investigate the possible influence of variation in ecological and demographic factors on the spatial organization of the terrestrial plethodontid salamander plethodon kentucki, i conducted a 3-year capture-recapture study and determined home-range characteristics and spatial relationships of individuals at two field sites that differed in predominant cover type and population density. home ranges of adults were fixed and the home ranges of same-sex adult neighbors were mostly exclusive. the s ... | 1998 | 28307552 |
