Lines of arrested growth (LAGs) were assessed in the Golestan Province population of the critically - endangered museum specimens of Persian mountain salamander, Paradactylodon gorganensis (Clergue-Gazeau and Thorn, 1979) from Northeastern Iran using skeletochronology. LAGs were clearly discernable in the tibia and femur bone cross-sections and could be interpreted for age determination. The nu...
Red spruce (Picea rubens) was historically an important and dominant timber species in the central Appalachian mountain range. The tree is now found a small fraction of its original home Threatened endangered organisms such as Cheat Mountain Salamander (Plethodon nettingi) rely on red associated forests for survival. This review provides background history forest management region. A meta-analy...
Eight different color polymorphisms of the Red-backed Salamander (Plethodon cinereus) have been described throughout its range. Among them, the erythristic phenotype is a mimetic morph with coloration patterns similar to that of toxic Eastern Newt efts (Notophthalmus viridescens). We describe an erythristic morph of P. cinereus collected at Mountain Lake Biological Station, Virginia. To our kno...
As part of the Wine Spring Creek ecosystem management project on the Nantahala National forest, North Carolina, we assessed effects of a community restoration ®re on small mammals and herpetofauna in the upper slope pitch pine (Pinus rigida) stands, neighboring midslope oak (Quercus spp.) stands and rhododendron (Rhododendron maximum) dominated riparian areas during 1995 and 1996. Using drift-f...
Climate change is currently considered a serious threat for many species and recognized as one of the most important factors in the global biodiversity loss. Among animal groups, amphibians are known to be among the most sensitive groups of vertebrates to climate change due to their inability to travel long distances, and mountain habitat species are more exposed to climate change pressures tha...
Abstract The Central Appalachian Spruce Restoration Initiative was formed to promote restoration of red spruce Picea rubens forests in Appalachia. One goal the initiative is increase availability and enhance quality habitat for wildlife, including threatened Cheat Mountain salamander Plethodon nettingi. purpose this research compare microhabitat characteristics between an occupied site early-st...
Starting in 2010, rapid fire salamander (Salamandra salamandra) population declines northwestern Europe heralded the emergence of Batrachochytrium salamandrivorans (Bsal), a salamander-pathogenic chytrid fungus. Bsal poses an imminent threat to global diversity owing its wide host range, high pathogenicity, and long-term persistence ecosystems. While there is pressing need develop further resea...
Ethological reproductive isolation and genetic divergence across 26 protein loci were measured among populations of the salamander Desmognathus ochrophaeus in the southern Appalachian Mountains. Levels of ethological isolation varied from none to complete and were statistically significant for all but two pairings between populations inhabiting different mountain ranges. When geographic and gen...
