Foundering lithosphere imaged beneath the southern Sierra Nevada, California, USA.
Seismic tomography reveals garnet-rich crust and mantle lithosphere descending into the upper mantle beneath the southeastern Sierra Nevada. The descending lithosphere consists of two layers: an iron-rich eclogite above a magnesium-rich garnet peridotite. These results place descending eclogite above and east of high P wave speed material previously imaged beneath the southern Great Valley, sug...
متن کاملPatterns of Natural and Human-Caused Mortality Factors of a Rare Forest Carnivore, the Fisher (Pekania pennanti) in California
Wildlife populations of conservation concern are limited in distribution, population size and persistence by various factors, including mortality. The fisher (Pekania pennanti), a North American mid-sized carnivore whose range in the western Pacific United States has retracted considerably in the past century, was proposed for threatened status protection in late 2014 under the United States En...
متن کاملGlaciations of the Sierra Nevada, California, USA
The Sierra Nevada is a c. 4000 m range of mountains paralle1 to the North American Pacific Coast that was repeatedly glaciated during the climatic fluchrations of the Quatemary. The glacial record on the eastem side of the range includes eight named Pleistocene glaciations and stadials: McGee, Sherwin, Casa Diablo, Mono Basin, Tahoe, Tenaya, Tioga and Recess Peak, as well as the Neoglacial Matt...
متن کاملNumic Expansion in the Southern Sierra Nevada
Recent research indicates that late prehistoric Numic expansion onto the western slope of the southern Sierra Nevada was facilitated by a competitive edge held by migrating groups, mainly Great Basinderived settlement and subsistence behaviors finetuned to the uncertainties of living in Little Ice Age mountain environments. But ethnographic, linguistic, and archaeological evidence also sugges...
متن کاملCharacterizing habitats associated with fisher den structures in the Southern Sierra Nevada, California using discrete return lidar
Lidar data provide information on the vertical and horizontal structure of forests, and lidar remote sensing can be effective in characterizing the forest habitats of mammals. This study explored the ability of lidar-derived metrics to capture topography and forest structure surrounding denning trees used by the Pacific fisher (Martes pennanti) as a case study to illustrate the utility of lidar...
