Environmental drivers of demography and potential factors limiting the recovery of an endangered marine top predator Environmental drivers of demography and potential factors limiting the recovery of an endangered marine top predator
Understanding what drives changes in wildlife demography is fundamental to the conservation and management of depleted or declining populations, though making inference about the intrinsic and extrinsic factors that influence survival and reproduction remains challenging. Here we use mark–resight data from 2000 to 2018 to examine the effects of environmental variability on age-specific...

Hidden in plain sight: Integrated population models to resolve partially observable latent population structure Hidden in plain sight: Integrated population models to resolve partially observable latent population structure
Population models often require detailed information on sex-, age-, or size-specific abundances, but population monitoring programs cannot always acquire data at the desired resolution. Thus, state uncertainty in monitoring data can potentially limit the demographic resolution of management decisions, which may be particularly problematic for stage- or size-structured species subject to

Multiple dimensions of functional diversity affect stream fish β-diversity Multiple dimensions of functional diversity affect stream fish β-diversity
When investigating metacommunity dynamics, functional differences among species are often assumed to be as important as environmental differences between sites in determining β-diversity. However, few studies have examined the influence of functional diversity on β-diversity. We examine the relative importance of regional functional diversity partitioned by niche dimensions and...

Comparing translocated beavers used as passive restoration tools to resident beavers in degraded desert rivers Comparing translocated beavers used as passive restoration tools to resident beavers in degraded desert rivers
Wildlife translocation facilitates conservation efforts, including recovering imperiled species, reducing human–wildlife conflict, and restoring degraded ecosystems. Beaver (American, Castor canadensis; Eurasian, C. fiber) translocation may mitigate human–wildlife conflict and facilitate ecosystem restoration. However, few projects measure outcomes of translocations by monitoring beaver

Do unpublished data help to redraw distributions? The case of the spectacled bear in Peru Do unpublished data help to redraw distributions? The case of the spectacled bear in Peru
Data availability remains a principal factor limiting the use of species distribution models (SDMs) as tools for wildlife conservation and management of rare species. Although data collected in systematic and rigorous fashion are preferable, available data for most species of conservation interest are usually low in both quality and number. Here we show that combining records published...

Long-term recovery of Mexican spotted owl nesting habitat after fire in the Lincoln National Forest, New Mexico Long-term recovery of Mexican spotted owl nesting habitat after fire in the Lincoln National Forest, New Mexico
Background Dry mixed-conifer forests of the southwestern United States are experiencing rapid, anthropogenically driven fire regime change. Prior to the Euro-American settlement, most of these forests experienced frequent surface fires but are now vulnerable to uncharacteristically large, high-severity fires. Fire directly influences the structure and composition of these forests and, in...

Ungulate migrations of the western United States, volume 3 Ungulate migrations of the western United States, volume 3
Ungulates (hooved mammals) have a broad distribution across the western United States and play an important role in maintaining predator-prey dynamics, affecting vegetation communities, and providing economic benefits to regional communities through tourism and hunting. Throughout the diverse landscapes they occupy, many ungulate populations undertake seasonal migrations to exploit...

Examining landowners’ preferences for a chronic wasting disease management program Examining landowners’ preferences for a chronic wasting disease management program
Private landowners are key partners in chronic wasting disease (CWD) management, especially in landscapes where there is limited public ownership. In this study, we evaluated landowners' preferences for alternative hypothetical CWD management programs using a stated choice experiment. We were particularly interested in understanding preferences for the use of financial incentives to...

Freshwater corridors in the conterminous US: A coarse-filter approach based on lake-stream networks Freshwater corridors in the conterminous US: A coarse-filter approach based on lake-stream networks
Maintaining regional-scale freshwater connectivity is challenging owing to the dendritic, easily fragmented structure of freshwater networks, but is essential for promoting ecological resilience under climate change. Although the importance of stream network connectivity has been recognized, lake-stream network connectivity has largely been ignored. Furthermore, protected areas are...

Diet composition and overlap for adult walleye, lake whitefish, and yellow perch in Green Bay, Lake Michigan Diet composition and overlap for adult walleye, lake whitefish, and yellow perch in Green Bay, Lake Michigan
Interspecific interactions among walleye Sander vitreus, lake whitefish Coregonus clupeaformis, and yellow perch Perca flavescens in Green Bay could influence the population status of each species, but potential trophic interactions are poorly understood. Our objectives were to determine if diet assemblages for each species and diet overlap among species varied spatially and temporally...

Comparison of two detection methods of a declining rodent, the Allegheny woodrat, in Virginia Comparison of two detection methods of a declining rodent, the Allegheny woodrat, in Virginia
Allegheny woodrats Neotoma magister are an imperiled small mammal species most associated with emergent rock habitats in the central Appalachian Mountains and the Ohio River Valley. The monitoring of populations and their spatiotemporal distributions typically has relied on labor-intensive livetrapping. The use of remote-detecting cameras holds promise for being an equally or more...
