Management stategies for ecological values in the face of climate change require reliable and focused information. In this technical...
Examining industry vulnerability: A focus on mineral commodities used in the automotive and electronics industries
Ross Manley, Elisa Alonso, Nedal T. Nassar
2022, Resources Policy (78)
Automotive manufacturing is material-intensive and dependent on a broad range of mineral commodities. Moreover, the automotive manufacturing industries are reliant on complex and sometimes opaque multi-tiered global supply chains. Among the many industries on which automotive supply chains depend are the electronics and semiconductor industries, which are themselves material-intensive and reliant on...

2022, Research Note RMRS-RN-94
Wildfire affects hundreds of wildland-urban interface communities each year, and yet most communities lack data reflecting the conditions before an event. This study was conducted before the devastating 2020 East Troublesome Fire1, which spread across 193,812 acres and resulted in two lives lost and 366 homes and 214 other structures...
Crowd-sourced SfM: Best practices for high resolution monitoring of coastal cliffs and bluffs
Phillipe Alan Wernette, Ian M. Miller, Andrew C. Ritchie, Jonathan Warrick
2022, Continental Shelf Research (245)
Structure from motion (SfM) photogrammetry is an increasingly common technique for measuring landscape change over time by deriving 3D point clouds and surface models from overlapping photographs. Traditional change detection approaches require photos that are geotagged with a differential GPS (DGPS) location, which requires expensive equipment that can limit the ability of communities and...

Editorial: Fire regimes in desert ecosystems: Drivers, impacts and changes
Eddie J. B. van Etten, Matthew L. Brooks, Aaron C. Greenville, Glenda M. Wardel
2022, Frontiers in Ecology and Evolution (10)
Although not commonly associated with fire, many desert ecosystems across the globe do occasionally burn, and there is evidence that fire incidences are increasing, leading to altered fire regimes in this biome. The increased prevalence of megafires (wildfires >10,000 ha in size and typically damaging) in most global biomes is...
Defining fine-scaled population structure among continuously distributed populations
Michael O'Donnell, David R. Edmunds, Cameron L. Aldridge, Julie A. Heinrichs, Adrian P. Monroe, Peter S. Coates, Brian G. Prochazka, Steve E. Hanser, Lief A. Wiechman
2022, Methods in Ecology and Evolution (13) 2222-2235
Understanding wildlife population structure and connectivity can help managers identify conservation strategies, as structure can facilitate the study of population changes and habitat connectivity can provide information on dispersal and biodiversity. To facilitate the use of wildlife monitoring data for improved adaptive management, we developed a novel approach to...
Analysis of provisioning ecosystem services and perceptions of climate change for indigenous communities in the Western Himalayan Gurez Valley, Pakistan
Uzma Saeed, Muhammad Arshad, Shakeel Hayat, Toni Lyn Morelli, Muhammad Ali Nawaz
2022, Ecosystem Services (56)
Climate change is a significant threat to people living in mountainous regions. It is essential to understand how montane communities currently depend especially on the provisioning ecosystem services (ES) and the ways in which climate change will impact these services, so that people can develop relevant adaptation strategies. The ES...
Volcano, earthquake, and tsunami hazards of the Cascadia Subduction Zone
Elizabeth G. Westby, Andrew J Meigs, Chris Goldfinger
2022, Elements (18) 251-256
Subduction zones produce some of Earth’s most devastating geological events. Recent eruptions of Mount St. Helens and great earthquakes and tsunamis in Japan and Sumatra provide stark examples of the destructive power of subduction-related hazards. In the Cascadia subduction zone, large earthquakes, tsunamis, and volcanic eruptions have occurred in the...
Rural turtles: Estimating the occupancy of Northwestern Pond Turtles and non-native red-eared sliders in agricultural habitats in California's Sacramento Valley and Sacramento-San Joaquin River Delta
Jonathan P. Rose, Brian J. Halstead, Alexandria M. Fulton
2022, Northwestern Naturalist (103) 97-109
The Northwestern Pond Turtle (Actinemys marmorata; WPT) was once widespread throughout the Sacramento Valley and the Sacramento-San Joaquin River Delta. Much of its historical range has been converted into agricultural land, reducing and altering aquatic habitat and surrounding uplands. Red-eared Sliders (Trachemys scripta elegans; RES)...

Calvin H. Stevens, Paul Stone
2022, SEPM Special Publication (113) 72-86
Mississippian sedimentary facies belts in east-central California, occurring primarily in the autochthon (lower plate) of the Last Chance Thrust, are consistently oriented in a northeast–southwest direction. The boundary of one belt is marked by the depositional limit of the Osagean to Meramecian Santa Rosa Hills Limestone; a second belt farther...

Justin T. Brandt
2022, Open-File Report 2022-1030
The locations of many faults in and near the Rialto-Colton groundwater subbasin are not precisely known because the spatial density of existing lithologic and hydrologic data used to infer the locations of faults can be sparse. The U.S. Geological Survey, in cooperation with the San Bernardino Valley Municipal Water District,...

Key observations of flexed-leg urination in the free-ranging Gray Wolf (Canis lupus)
L. David Mech, Rick McIntyre
2022, Canadian Field Naturalist (136) 10-12
Flexed-leg urination (FLU) in female Gray Wolves (Canis lupus) has been little studied in the wild. Captive females in packs do not exhibit FLU unless they are both mature and dominant to an associate female, but these characteristics have not been confirmed in free-ranging wolves. We present observations of...
