Ungulate migrations of the Western United States, volume 6 Ungulate migrations of the Western United States, volume 6
This report, volume 6 in the “Ungulate Migrations of the Western United States” report series, showcases the migrations of 23 ungulate herds in the Western United States. The report series is produced by the Corridor Mapping Team (CMT). Led by the U.S. Geological Survey, the CMT is a collaboration among 11 State agencies, as well as regional and Federal partners, and an expanding number...

Cost of migration increased during an outbreak of highly pathogenic avian influenza virus Cost of migration increased during an outbreak of highly pathogenic avian influenza virus
Migration is thought to be costly such that challenges faced during migration likely affect how birds migrate through direct selection on migratory behavior. Survival throughout the annual cycle and conditions that affect the survival costs of migration are therefore critical to our understanding of the causes and consequences of migration. Estimating daily survival throughout the annual...

Leveraging local species data, a global database, and an occupancy model to explore bee–plant interactions Leveraging local species data, a global database, and an occupancy model to explore bee–plant interactions
Global declines in bee populations are threatening the ecosystem services they provide, including pollination. Many bee–plant interactions are understudied, producing an incomplete understanding of resulting ecosystem-level vulnerabilities. The last decade has generated a wealth of opportunistic data originating from natural history collection records, published ecological datasets, and...

Adaptive capacity of freshwater organisms in North America: Current understanding and future applications Adaptive capacity of freshwater organisms in North America: Current understanding and future applications
Freshwater species are increasingly threatened by climate change, yet our ability to assess their vulnerability remains incomplete. Typically, climate change vulnerability assessments (CCVAs) evaluate three components: exposure, sensitivity, and adaptive capacity. Adaptive capacity, defined as the ability of a species to adjust to changing conditions, provides critical insight into how...

Is new actually better? A structural comparison of collaborative governance structures for the management of Atlantic salmon (Salmo salar) in Maine Is new actually better? A structural comparison of collaborative governance structures for the management of Atlantic salmon (Salmo salar) in Maine
Collaborative governance structures (CGS) have been increasingly adopted to address joint-jurisdictional management challenges. While the establishment of CGSs has been widely studied, their practical development has remained a conspicuous gap. CGSs are variable systems with several developmental stages (activation, collectivity, and institutionalization) which eventually lead to...

Statewide agent-based model for management of chronic wasting disease in white-tailed deer: PAOvCWD Statewide agent-based model for management of chronic wasting disease in white-tailed deer: PAOvCWD
Chronic wasting disease (CWD) is an always-fatal disease infecting wild cervids globally. Ecologically and economically important, CWD presents a challenge for managing white-tailed deer (Odocoileus virginianus). We built an agent-based model to simulate CWD transmission and assess potential management actions that could slow disease spread: PAOvCWD. We developed PAOvCWD using contact...

Resilience thinking for human-wildlife coexistence: Bridging dynamic systems, archetypes, and transformations Resilience thinking for human-wildlife coexistence: Bridging dynamic systems, archetypes, and transformations
As human activities and wildlife increasingly overlap in the Anthropocene, conventional conservation paradigms focused on land-sparing are shifting toward strategies that support human–wildlife coexistence. However, achieving sustainable coexistence is often hindered by a limited understanding of the dynamic social–ecological processes that drive integrated human–wildlife systems. This...

Spatial behavior of socially isolated wild pigs (Sus scrofa) following sounder removal via trapping Spatial behavior of socially isolated wild pigs (Sus scrofa) following sounder removal via trapping
BACKGROUND The rapid expansion of wild pig (Sus scrofa) populations across North America, coupled with increased concern over disease transmission, has intensified the need for effective management strategies. Trapping is widely regarded as the most effective control method; however, trapping events often fail to capture entire sounders. The behavioral responses of untrapped individuals...

Finding the (small) cores: Spatial covariance tracks grassland bird community occupancy in fragmented grasslands Finding the (small) cores: Spatial covariance tracks grassland bird community occupancy in fragmented grasslands
Grasslands are an imperiled ecosystem, and grassland bird abundance is declining across North America. One of the strongest drivers for these declines is woody plant encroachment of grasslands. In the Great Plains and Sagebrush biomes of North America, spatial covariance—a remote-sensing metric for tracking boundaries between vegetation types—is emerging as a new method to identify and...

Hydrologic variability drives environmental and geospatial relationships in Smallmouth Bass (Micropterus dolomieu) distribution Hydrologic variability drives environmental and geospatial relationships in Smallmouth Bass (Micropterus dolomieu) distribution
Hydrologic variation is a primary driver of stream ecosystems. Changing hydrology can lead to assemblage shifts and alterations in suitable habitat for freshwater species. As climate change is predicted to alter flow patterns in addition to increasing water temperatures, insight into relationships between species occupancy, hydrology, and temperature is critical for understanding current...

Seasonal and hydrologic variation influences habitat and functional structure of stream fish assemblages Seasonal and hydrologic variation influences habitat and functional structure of stream fish assemblages
Introduction: Hydrologic variability is a key driver of ecological structure in lotic systems, shaping habitat conditions, taxonomic diversity, and the functional traits that mediate species’ persistence and performance (e.g., reproductive success). While many studies examine taxonomic responses to variation in flows, few evaluate how spatiotemporal hydrologic variation influences the...

Evaluating alternative methods for modeling trap efficiencies of out-migrating juvenile salmonids Evaluating alternative methods for modeling trap efficiencies of out-migrating juvenile salmonids
Objective We aimed to compare two machine learning approaches—boosted beta regression (BBR) and beta mixed model forest (BMF)—to a Bayesian mixed-effects beta regression (BME) for the prediction of rotary screw trap (RST) efficiency for out-migrating juvenile salmonids from environmental covariates.Methods We identified two machine learning approaches that shared the ability to model...
