Vegetation and precipitation shifts interact to alter organic and inorganic carbon storage in cold desert soils
Dryland ecosystems are experiencing shifts in rainfall and plant community composition, which are expected to alter cycling and storage of soil carbon (C). Few experiments have been conducted to examine long‐term effects on (1) soil organic C (SOC) pools throughout the soil profile, and (2) soil inorganic C (SIC) pools as they relate to dynamic...Huber, David P.; Lohse, Kathleen A.; Commendador, Amy; Joy, Stephen; Aho, Ken A.; Finney, Bruce P.; Germino, Matthew J.
Trends in landbird density at two national parks in fragmented, mixed-use landscapes of the Pacific Northwest
National parks play a key role in conserving species by providing landscapes where threats from anthropogenic disturbance are reduced. In a recent study of 3 large wilderness parks in the Pacific Northwest, nearly all landbird species were found to be stable or increasing. Nonetheless, contemporary results from the Breeding Bird Survey and mark-...Holmgren, M.; Wilkerson, R.; Siegel, R.; Ransom, J.; Jenkins, Kurt J.; Boetsch, J.; Ray, Chris; Holmgren, Mandy; Wilkerson, Robert L.; Siegel, Rodney B.; Boetsch, John R.; Jenkins, Kurt J.; Ransom, Jason I.
An improved mechanical owl for efficient capture of nesting raptors
Scientific study of raptors often requires the use of a lure to capture individuals for marking or collecting various data and samples. Live lure owls in the genus Bubo are commonly used with mist nets or dho-gazas to trap nesting raptors, but the use of these live lures presents ethical, logistical, and financial challenges. Although...Jensen, Meghan K.; Hamburg, Shanti D.; Rota, Christopher T.; Brinker, David F.; Coles, Dustin L.; Manske, Mark A.; Slabe, Vincent A.; Stuber, Matthew J.; Welsh, Amy B.; Katzner, Todd E.
Adaptive variation, including local adaptation, requires decades to become evident in common gardens
Population‐level adaptation to spatial variation in factors such as climate and soils is critical for climate‐vulnerability assessments, restoration seeding, and other ecological applications in species management, and the underlying information is typically based on common‐garden studies that are short duration. Here, we show >20 yr were...Germino, Matthew J.; Moer, Ann M.; Sands, Alan R.
Simulating demography, genetics, and spatially explicit processes to inform reintroduction of a threatened char
The success of species reintroductions can depend on a combination of environmental, demographic, and genetic factors. Although the importance of these factors in the success of reintroductions is well‐accepted, they are typically evaluated independently, which can miss important interactions. For species that persist in metapopulations, movement...Mims, Meryl C.; Day, Casey C.; Burkhart, Jacob J.; Fuller, Matthew R.; Hinkle, Jameson; Bearlin, Andrew; Dunham, Jason B.; DeHaan, Patrick W.; Holden, Zachary A.; Landguth, Erin L.
Compounding effects of climate change reduce population viability of a montane amphibian
Anthropogenic climate change presents challenges and opportunities to the growth, reproduction, and survival of individuals throughout their life cycles. Demographic compensation among life‐history stages has the potential to buffer populations from decline, but alternatively, compounding negative effects can lead to accelerated population decline...Kissel, Amanda M.; Palen, Wendy J.; Ryan, Maureen E.; Adams, Michael J.
Conceptualizing ecological responses to dam removal: If you remove it, what's to come?
One of the desired outcomes of dam decommissioning and removal is the recovery of aquatic and riparian ecosystems. To investigate this common objective, we synthesized information from empirical studies and ecological theory into conceptual models that depict key physical and biological links driving ecological responses to removing dams. We...Bellmore, J. Ryan; Pess, George R.; Duda, Jeffrey J.; O'Connor, Jim E.; East, Amy E.; Foley, Melissa M.; Wilcox, Andrew C.; Major, Jon J.; Shafroth, Patrick B.; Morley, Sarah A.; Magirl, Christopher S.; Anderson, Chauncey W.; Evans, James E.; Torgersen, Christian E.; Craig, Laura S.
Phenology of hatching, emergence, and end-of-season body size in young-of-year Coho Salmon in thermally contrasting streams draining the Copper River Delta, Alaska
Phenology can be linked to individual fitness, particularly in strongly seasonal environments where the timing of events have important consequences for growth, condition, and survival. We studied the phenology of Coho Salmon hatching and emergence in streams with contrasting thermal variability, but in close geographic proximity. Following...Campbell, Emily Y.; Dunham, Jason B.; Reeves, Gordon H.; Wondzell, Steve M.
Gene flow connects coastal populations of a habitat specialist, the Clapper Rail Rallus crepitans
Examining population genetic structure can reveal patterns of reproductive isolation or population mixing and inform conservation management. Some avian species are predicted to exhibit minimal genetic differentiation among populations as a result of the species high mobility, with habitat specialists tending to show greater fine‐scale genetic...Coster, Stephanie S.; Welsh, Amy B.; Costanzo, Gary R.; Harding, Sergio R.; Anderson, James T.; Katzner, Todd E.
Identification of bees in southwest Idaho—A guide for beginners
This document was prepared to help scientists and the public, both of whom may not be familiar with bee taxonomy, learn how to practically identify bees in sagebrush steppe and shrubland habitats in southwest Idaho. We provide information to identify bees to the level of family and genus. A tentative list of the bee genera captured at sites used...Sun, Emily R.; Pilliod, David S.
Prevalence and risk factors of Trichomonas gallinae and trichomonosis in golden eagle (Aquila chrysaetos) nestlings in western North America
Avian trichomonosis, caused by the protozoan Trichomonas gallinae, affects bird-eating raptors worldwide. Raptors can develop trichomonosis by feeding on infected prey, particularly Rock Pigeons (Columba livia), which are a reservoir for T. gallinae. Raptors may be particularly vulnerable to T. gallinae infection in degraded...Dudek, Benjamin M; Kochert, Michael N.; Barnes, Joseph G.; Bloom, Peter H.; Papp, Joseph M.; Gerhold, Richard W.; Purple, Kathryn E.; Jacobson, Kenneth V.; Preston, Charles R.; Vennum, Chris R.; Watson, James W.; Heath, Julie A.
Natural resource condition assessment: Olympic National Park
The Natural Resource Assessment Program aims to document condition and trends of selected park resources while identifying emerging issues and information needs. This information is intended to serve as a platform for natural resource managers to use in developing future resource stewardship priorities and planning.Olympic National Park (OLYM) on...Mccaffery, Rebecca; Jenkins, Kurt J.
