Impacts of Forest Harvesting on the Long-toed Salamander (Ambystoma macrodactylum) at Opax Mountain
Natural biodiversity in forests has become the focus of increased attention in recent years and maintaining this biodiversity is now an important management goal. Amphibians are an important, though somewhat invisible, component of forest biodiversity, differing considerably from other vertebrates in their physiology, behaviour and role in food webs. Their small size and ability to convert ener...
متن کاملThe influence of altitude and topography on genetic structure in the long-toed salamander (Ambystoma macrodactulym).
A primary goal of molecular ecology is to understand the influence of abiotic factors on the spatial distribution of genetic variation. Features including altitudinal clines, topography and landscape characteristics affect the proportion of suitable habitat, influence dispersal patterns, and ultimately structure genetic differentiation among populations. We studied the effects of altitude and t...
متن کاملEffects of atrazine and iridovirus infection on survival and life-history traits of the long-toed salamander (Ambystoma macrodactylum).
Environmental contaminants and emerging infectious diseases are implicated as factors contributing to global amphibian declines. However, few studies have tested the interaction of these factors. We exposed six-week-old, larval long-toed salamanders (Ambystoma macrodactylum) to Ambystoma tigrinum virus (ATV; 0 or 10(3.5) plaque-forming units/ml) and sublethal concentrations of atrazine (0, 1.84...
متن کاملLarge geographic range size reflects a patchwork of divergent lineages in the long-toed salamander (Ambystoma macrodactylum).
For northern taxa, persistence in multiple vs. single Pleistocene refugia may have been an important determinant of contemporary range size, with larger ranges achieved by species that colonized the north from several glacial refugia. Under this hypothesis, widespread species are expected to demonstrate marked phylogeographic structure in previously glaciated regions. We use a genome-wide surve...
متن کاملthe role of thematic structure in comprehending spoken language
in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...
