From satellites to frogs: Quantifying ecohydrological change, drought mitigation, and population demography in desert meadows
Increasing frequency and severity of droughts have motivated natural resource managers to mitigate harmful ecological and hydrological effects of drought, but drought mitigation is an emerging science and evaluating its effectiveness is difficult. We examined ecohydrological responses of drought mitigation actions aimed at conserving populations...
Pilliod, David; Hausner, Mark B.; Scherer, Rick D. The snag’s the limit: Habitat selection modeling for the western purple martin in a managed forest landscape
The western purple martin (Progne subis arboricola), an avian insectivore, is a species of conservation concern throughout the Pacific Northwest. Compared to the well-studied eastern subspecies (Progne subis subis), little is known of the life history and biology of the western subspecies. Availability of breeding habitat is believed to be a major...
Sherman, Lorelle M.; Hagar, Joan High frequency of lead exposure in the population of an endangered Australian top predator, the Tasmanian wedge-tailed eagle (Aquila audax fleayi)
Lead poisoning, mainly through incidental ingestion of lead ammunition in carcasses, is a threat to scavenging and predatory bird species worldwide. In Australia, shooting for animal control is widespread, and a range of native scavenging species are susceptible to lead exposure. However, the prevalence of lead exposure in Australia's scavenging...
Pay, James M.; Katzner, Todd E.; Hawkins, Clare E.; Koch, Amelia J.; Wiersm, Jason M.; Brown, William E.; Mooney, Nick J.; Cameron, Elissa Z. Weed-suppressive bacteria effects differ in culture compared to in soils and with or without microbial competition and separation of active ingredient
Weed-suppressive bacteria (WSB), specifically the D7 and ACK55 strains of Pseudomonas fluorescens, were previously reported to selectively inhibit growth of invasive annual grasses (IAGs) that have caused severe ecosystem degradation across much of the western US. However, recent studies show highly mixed evidence for WSB effectiveness in...
Lazarus, Brynne E.; Feris, Kevin; Germino, Matthew Conservation genetics of imperiled striped whipsnake in Washington
Conservation of wide-ranging species is aided by population genetic information that provides insights into adaptive potential, population size, interpopulation connectivity, and even extinction risk in portions of a species range. The Striped Whipsnake (Masticophis taeniatus) occurs across 11 western U.S. states and into Mexico but has...

Western purple martin (Progne subis arboricola) occurrence on the Siuslaw National Forest, Summer 2019
The western subspecies of the purple martin (Progne subis arboricola) is currently listed as a “critically” sensitive species in four ecoregions of western Oregon: Coast Range, Klamath Mountains, West Cascades, and Willamette Valley (Oregon Department of Fish and Wildlife, 2019). Importantly distinct from the abundant and widespread eastern...
Hagar, Joan; Branch, Eric Comparing methods to estimate the proportion of turbine-induced bird and bat mortality in the search area under a road and pad search protocol
Estimating bird and bat mortality at wind facilities typically involves searching for carcasses on the ground near turbines. Some fraction of carcasses inevitably lie outside the search plots, and accurate mortality estimation requires accounting for those carcasses using models to extrapolate from searched to unsearched areas. Such models should...
Maurer, Joseph; Huso, Manuela; Dalthorp, Daniel; Madsen, Lisa; Fuentes, Claudio Nowhere to hide: The importance of instream cover for stream‐living Coastal Cutthroat Trout during seasonal low flow
Through their multiple functions, refuges may be important for stream‐living fishes, particularly during stressful events such as seasonal low flow or drought. Coastal Cutthroat Trout Oncorhynchus clarkii clarkii is an ideal study organism to understand the importance of refuge. During seasonal low flow, lower water levels limit access...
Penaluna, Brooke E; Dunham, Jason B.; Andersen, Heidi V Evaluating a rapid field assessment system for anticoagulant rodenticide exposure of raptors
Anticoagulant rodenticides (ARs) are commonly used to control rodent pests. However, worldwide, their use is associated with secondary and tertiary poisoning of nontarget species, especially predatory and scavenging birds. No medical device can rapidly test for AR exposure of avian wildlife. Prothrombin time (PT) is a useful biomarker for AR...
Dickson, Ariana J; Belthoff, James R.; Mitchell, Kristen A; Smith, Brian W.; Wallace, Zachary P.; Stuber, Matthew J.; Lockhart, Michael J; Rattner, Barnett A.; Katzner, Todd E. Harvester ant seed removal in an invaded sagebrush ecosystem: Implications for restoration
A better understanding of seed movement in plant community dynamics is needed, especially in light of disturbance‐driven changes and investments into restoring degraded plant communities. A primary agent of change within the sagebrush‐steppe is wildfire and invasion by non‐native forbs and grasses, primarily cheatgrass (Bromus tectorum). Our...
Paolini, Kelsey E; Modlin, Matthew; Suazo, Alexis A; Pilliod, David; Arkle, Robert; Vierling, Kerri T.; Holbrook, Joseph D. Diurnal timing of nonmigratory movement by birds: The importance of foraging spatial scales
Timing of activity can reveal an organism's efforts to optimize foraging either by minimizing energy loss through passive movement or by maximizing energetic gain through foraging. Here, we assess whether signals of either of these strategies are detectable in the timing of activity of daily, local movements by birds. We compare the similarities...

Annotated bibliography of scientific research on greater sage-grouse published from 2015 to 2019
The greater sage-grouse (Centrocercus urophasianus; hereafter GRSG) has been a focus of scientific investigation and management action for the past two decades. The 2015 U.S. Fish and Wildlife Service listing determination of “not warranted” was in part due to a large-scale collaborative effort to develop strategies to conserve GRSG populations...
