Land cover changes associated with recent energy development in the Williston Basin; Northern Great Plains, USA Land cover changes associated with recent energy development in the Williston Basin; Northern Great Plains, USA
The Williston Basin in the Northern Great Plains has experienced rapid energy development since 2000. To evaluate the land cover changes resulting from recent (2000 – 2015) development, the area and previous land cover of all well pads (pads) constructed during this time was determined, the amount of disturbed and reclaimed land adjacent to pads was estimated, land cover changes were...

Conservation of native Pacific trout diversity in western North America Conservation of native Pacific trout diversity in western North America
Pacific trout Oncorhynchus spp. in western North America are strongly valued in ecological, socioeconomic, and cultural views, and have been the subject of substantial research and conservation efforts. Despite this, the understanding of their evolutionary histories, overall diversity, and challenges to their conservation is incomplete. We review the state of knowledge on these important...

New challenges for grizzly bear management in Yellowstone National Park New challenges for grizzly bear management in Yellowstone National Park
A key factor contributing to the success of grizzly bear Ursus arctos conservation in the Greater Yellowstone Ecosystem has been the existence of a large protected area, Yellowstone National Park. We provide an overview of recovery efforts, how demographic parameters changed as the population increased, and how the bear management program in Yellowstone National Park has evolved to...

Where the wild things are: A research agenda for studying wildlife-wilderness relationship Where the wild things are: A research agenda for studying wildlife-wilderness relationship
We explore the connection between US designated wilderness areas and wildlife with the goal of establishing a research agenda for better understanding this complex relationship. Our research agenda has two components. The first, “wildlife for wilderness,” considers the impact of wildlife on wilderness character. Whereas studies show that wildlife is important in both the perception and...

Diet and macronutrient optimization in wild ursids: A comparison of grizzly bears with sympatric and allopatric black bears Diet and macronutrient optimization in wild ursids: A comparison of grizzly bears with sympatric and allopatric black bears
When fed ad libitum, ursids can maximize mass gain by selecting mixed diets wherein protein provides 17 ± 4% of digestible energy, relative to carbohydrates or lipids. In the wild, this ability is likely constrained by seasonal food availability, limits of intake rate as body size increases, and competition. By visiting locations of 37 individuals during 274 bear-days, we documented...

Accounting for adaptive capacity and uncertainty in assessments of species’ climate-change vulnerability Accounting for adaptive capacity and uncertainty in assessments of species’ climate-change vulnerability
Climate change vulnerability assessments (CCVAs) are valuable tools for assessing species’ vulnerability to climatic changes, yet failure to include measures of adaptive capacity and to account for sources of uncertainty may limit their effectiveness. Here, we provide a more comprehensive CCVA approach that incorporates all three elements used for assessing species’ climate change...

Genomics reveals historic and contemporary transmission dynamics of a bacterial disease among wildlife and livestock Genomics reveals historic and contemporary transmission dynamics of a bacterial disease among wildlife and livestock
Whole-genome sequencing has provided fundamental insights into infectious disease epidemiology, but has rarely been used for examining transmission dynamics of a bacterial pathogen in wildlife. In the Greater Yellowstone Ecosystem (GYE), outbreaks of brucellosis have increased in cattle along with rising seroprevalence in elk. Here we use a genomic approach to examine Brucella abortus...

Linkages between unpaved forest roads and streambed sediment: why context matters in directing road restoration Linkages between unpaved forest roads and streambed sediment: why context matters in directing road restoration
Unpaved forest roads remain a pervasive disturbance on public lands and mitigating sediment from road networks remains a priority for management agencies. Restoring roaded landscapes is becoming increasingly important for many native coldwater fishes that disproportionately rely on public lands for persistence. However, effectively targeting restoration opportunities requires a...

“One Health” or three? Publication silos among the One Health disciplines “One Health” or three? Publication silos among the One Health disciplines
The One Health initiative is a global effort fostering interdisciplinary collaborations to address challenges in human, animal, and environmental health. While One Health has received considerable press, its benefits remain unclear because its effects have not been quantitatively described. We systematically surveyed the published literature and used social network analysis to measure

Movement and survival of an amphibian in relation to sediment and culvert design Movement and survival of an amphibian in relation to sediment and culvert design
Habitat disturbance from stream culverts can affect aquatic organisms by increasing sedimentation or forming barriers to movement. Land managers are replacing many culverts to reduce these negative effects, primarily for stream fishes. However, these management actions are likely to have broad implications for many organisms, including amphibians in small streams. To assess the effects...

Increasing influence of air temperature on upper Colorado River streamflow Increasing influence of air temperature on upper Colorado River streamflow
This empirical study examines the influence of precipitation, temperature, and antecedent soil moisture on upper Colorado River basin (UCRB) water year streamflow over the past century. While cool season precipitation explains most of the variability in annual flows, temperature appears to be highly influential under certain conditions, with the role of antecedent fall soil moisture less...
