Population Dynamics of Ouachita Dusky Salamanders (Desmognathus brimleyorum) in a Managed Forest Landscape
… salamander endemic to the Ouachita Mountains, Desmognathus brimleyorum. We specifically focused on two possible mechanisms of salamander abundance shifts, survival and movement. We conducted a capture-mark-recapture (CMR) study at three streams within intensely managed pine forests in …

Phylogenetic History, Morphological Parallelism, and Speciation in a Complex of Appalachian Salamanders (Genus: Desmognathus)
… lineages using morphological characters. Desmognathus salamanders are an ideal group for testing hypotheses concerning the correlation between morphological similarity and genetic exchange within and among nominal species due to a pattern of high discordance between the two. …

The Impact of Logging on Aquatic Salamander Communities.
… used as indicators; two of these species (<em>Desmognathus quadramaculatus</em> and <em>Desmognathus ochrophaeus</em>) were negatively affected by the logging, while four species (<em>Demognathus fuscus</em>, <em>Desmognathus monticola</em>, <em>Eurycea wilderae</em>, and <em>Gyrinophilus …

Comparison of herpetofaunal species composition and response to edge on the Camp Dawson Collective Training Area, Preston County, West Virginia
… in pitfall arrays; mountain dusky salamander (Desmognathus ochrophaeus), Appalachian seal salamander (Desmognathus m. monticola), and redback salamander were most common from searches. Northern red salamander ( Pseudotriton r. ruber), a West Virginia rare species, was documented on all 3 study …

The Effects of Microhabitat and Land Use on Stream Salamander Occupancy and Abundance in the Southwest Virginia Coalfields
… My findings indicate that dusky salamander (Desmognathus spp.) occupancy and abundances are more correlated to microhabitat parameters such as canopy cover than to subwatershed land uses. Brook salamander (Eurycea spp.) occupancy show negative associations to large-scale land uses such as …

Quantifying Metagonimoides oregonensis infection distribution and effects among stream salamander hosts
… among the species. Of the six species, Desmognathus quadramaculatus may be most important in transmission, as they had the highest prevalence and intensity of infection. This may be due to their long larval period, which results in a longer trematode accrual period. My second study …

Amphibian and Reptile Community Responses to Forest and Riparian Disturbance
… growth of the Ouachita dusky salamander (Desmognathus brimleyorum). We used intensive capture-mark-recapture at three headwater streams embedded in intensely managed pine forests of west-central Arkansas, employing a Before-After-Control-Impact (BACI) design. Collectively, our results …

RESISTANCE AND RESILIENCE OF STREAM SALAMANDER POPULATIONS TO DISTURBANCE
Urbanization and drought represent two pervasive disturbances that affect animal inhabitants of small, first-order streams. Stream salamanders (Family Plethodontidae) represent the dominant vertebrate group and play important ecological roles in first-order streams, although they have often been …
