Exposure to risk factors experienced during migration is not associated with recent Vermivora warbler population trends Exposure to risk factors experienced during migration is not associated with recent Vermivora warbler population trends
Context Understanding the factors limiting populations of animals is critical for effective conservation. Determining which factors limit populations of migratory species can be especially challenging because of their reliance on multiple, often geographically distant regions during their annual cycles.Objectives We investigated whether distribution-wide variation in recent breeding...

Invasive Brook Stickleback Culaea inconstans occurrence, habitat drivers, and spatial overlap with native fishes in Wyoming, USA Invasive Brook Stickleback Culaea inconstans occurrence, habitat drivers, and spatial overlap with native fishes in Wyoming, USA
A central focus of modern fisheries management is eradicating invaders that threaten imperiled native fishes. However, vast landscapes and limited funding and personnel resources demand a prioritized approach to management. Brook Stickleback Culaea inconstans (Kirtland, 1840) is an aquatic invasive species in Wyoming, USA, that may pose a risk to native biodiversity. Our aim was to...

Wetland management practices and secretive marsh bird habitat in the Mississippi Flyway: A review Wetland management practices and secretive marsh bird habitat in the Mississippi Flyway: A review
Management regimes on publicly owned freshwater wetlands in the Mississippi Flyway of North America (i.e., Flyway) have historically emphasized waterfowl, but there is limited information on how waterfowl-focused wetland management affects other wetland-dependent wildlife. Secretive marsh birds (SMBs) depend on wetlands with emergent vegetation throughout their migratory life cycle and...

Pollinator conservation and climate science at the U.S. Geological Survey Pollinator conservation and climate science at the U.S. Geological Survey
Introduction Ecosystems—whether agricultural, urban, or natural—depend on pollinators, great and small. Pollinators in the form of bees, birds, butterflies, bats, and even moths provide vital, but often invisible services, from contributing to biodiverse terrestrial wildlife and plant communities to supporting healthy watersheds. Pollinator declines worldwide have been noted as land-use...

Turkey Vulture survival is reduced in areas of greater road density Turkey Vulture survival is reduced in areas of greater road density
The demography of, and factors that influence these metrics, are largely unknown for most vultures in the Americas. Survivorship of Turkey Vultures (Cathartes aura) may be influenced by landscape heterogeneity and human disturbance. We quantified the effects of landscape composition (Shannon’s diversity index) and configuration (contagion, edge density, and largest patch index), and...

Integrating community science and agency-collected monitoring data to expand monitoring capacity at large spatial scales Integrating community science and agency-collected monitoring data to expand monitoring capacity at large spatial scales
Monitoring species to better understand their status, ecology, and management needs is a major expense for agencies tasked with biodiversity conservation. Community science data have the potential to improve monitoring for minimal cost, given appropriate analytical frameworks. We describe a framework for integrating data from the eBird community science platform with agency-collected...

Fall migration, oceanic movement, and site residency patterns of eastern red bats (Lasiurus borealis) on the mid-Atlantic Coast Fall migration, oceanic movement, and site residency patterns of eastern red bats (Lasiurus borealis) on the mid-Atlantic Coast
Along the mid-Atlantic coast of the United States, eastern red bats (Lasiurus borealis) are present during fall mating and migration, though little is currently known about most aspects of bat migration. To reveal migration patterns, and understand drivers of over-water flight, we captured and radio-tagged 115 eastern red bats using novel technology, and subsequently tracked and...

Examining dynamic occupancy of gray wolves in Idaho after a decade of managed harvest Examining dynamic occupancy of gray wolves in Idaho after a decade of managed harvest
Gray wolves (Canis lupus) were reintroduced to Idaho, USA, in 1995–1996. The removal of Endangered Species Act protections in 2011 transferred wolf management to the state where wolves were subsequently classified as a harvested (i.e., hunted, trapped) big game species. We implemented a camera-based survey across Idaho from 2016–2021 as part of a population monitoring program. We used...

Validation and comparison of age estimates for Smallmouth Buffalo in Oklahoma based on otoliths, pectoral fin rays, and opercula Validation and comparison of age estimates for Smallmouth Buffalo in Oklahoma based on otoliths, pectoral fin rays, and opercula
With an increased interest in nongame fishes such as buffalofishes (Catostomidae, Ictiobus), there is a need for better foundational data on their life history. Bigmouth Buffalo I. cyprinellus, for example, have been found to live for more than a century. Age estimates for other sucker species have similarly suggested long life spans, but validation studies as reference points are often...

Behavioral responses of terrestrial mammals to COVID-19 lockdowns Behavioral responses of terrestrial mammals to COVID-19 lockdowns
COVID-19 lockdowns reduced human mobility, providing an opportunity to disentangle its effects on animals from those of landscape modifications. Using GPS data, we compared movements and road avoidance of 2300 terrestrial mammals (43 species) during the 2020 lockdowns to the same period in 2019. Individual responses were variable, with no change in average movements or road avoidance...
