| estimation of core terrestrial habitat for stream-breeding salamanders and delineation of riparian buffers for protection of biodiversity. | many species of wildlife depend on riparian habitats for various life-history functions (e.g., breeding, foraging, overwintering). although this unique habitat is critical for many species, delineations of riparian zones and buffers for various taxa are lacking. typically when buffer zones are determined to mitigate edge effects, they are based on criteria that protect aquatic resources alone and do not consider impacts to wildlife and other terrestrial resources. using two different survey meth ... | 2007 | 17298521 |
| variable infection of stream salamanders in the southern appalachians by the trematode metagonimoides oregonensis (family: heterophyidae). | many factors contribute to parasites varying in host specificity and distribution among potential hosts. metagonimoides oregonensis is a digenetic trematode that uses stream-dwelling plethodontid salamanders as second intermediate hosts in the eastern us. we completed a field survey to identify which stream salamander species, at a regional level, are most likely to be important for transmission to raccoon definitive hosts. we surveyed six plethodontid species (n = 289 salamanders) from 23 appal ... | 2015 | 26026670 |
| salamander growth rates increase along an experimental stream phosphorus gradient. | nutrient-driven perturbations to the resource base of food webs are predicted to attenuate with trophic distance, so it is unclear whether higher-level consumers will generally respond to anthropogenic nutrient loading. few studies have tested whether nutrient (specifically, nitrogen [n] and phosphorus [p]) enrichment of aquatic ecosystems propagates through multiple trophic levels to affect predators, or whether n vs. p is relatively more important in driving effects on food webs. we conducted ... | 2015 | 27070018 |
| interactive effects of temperature and glyphosate on the behavior of blue ridge two-lined salamanders (eurycea wilderae). | the objective of the present study was to evaluate the potential interactive effects of stream temperatures and environmentally relevant glyphosate-based herbicide concentrations on movement and antipredator behaviors of larval eurycea wilderae (blue ridge two-lined salamander). larval salamanders were exposed to 1 of 4 environmentally relevant glyphosate concentrations (0.00 µg acid equivalent [a.e.]/l, 0.73 µg a.e./l, 1.46 µg a.e./l, and 2.92 µg a.e./l) at either ambient (12 °c) or elevated (2 ... | 2016 | 26872413 |
