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...

Life history traits and population dynamics of Freshwater Drum across large river gradients Life history traits and population dynamics of Freshwater Drum across large river gradients
Objective Monitoring and assessment of nongame native fishes is limited, but conservation interest in these species is growing. Freshwater Drum Aplodinotus grunniens are a wide-ranging species that serve important functional roles and could serve as an indicator for similar but less common species. Our overall objectives were to quantify and compare population dynamic rates and life...

Life-history stages and behavior influence demographic classification of moose captured on remote cameras Life-history stages and behavior influence demographic classification of moose captured on remote cameras
Obtaining accurate information on demographic states, such as the age and sex classes of animals, is an important step for monitoring wildlife populations. Traditionally, demographic data are collected from harvest, aerial surveys and telemetry studies. However, these methods can be expensive, limited to small spatial scales, or biased due to human behavior. Remote cameras have become a...

Line transect distance sampling and genetic analyses reveal a small but genetically diverse coastal Gopher Tortoise (Gopherus polyphemus) population Line transect distance sampling and genetic analyses reveal a small but genetically diverse coastal Gopher Tortoise (Gopherus polyphemus) population
Gopher Tortoises inhabit coastal systems, including barrier islands, across the southeastern U.S. St. Vincent National Wildlife Refuge is an uninhabited barrier island located off the coast of northwestern Florida. Although tortoises have been observed on the island, no information is available on the status of the population. We conducted a line transect distance sampling survey to...

Linking community-climate disequilibrium to ecosystem function Linking community-climate disequilibrium to ecosystem function
Turnover in species composition often lags behind the pace of climate change, resulting in mismatches between climate and communities. However, the impact of these community-climate disequilibria on ecosystem functions is rarely considered, and current methods for measuring disequilibria assume that species ranges were, until recently, in equilibrium with climate. Here, we develop a...

Linking distribution and return-on-investment models to optimize woody management for prairie grouse in Nebraska Linking distribution and return-on-investment models to optimize woody management for prairie grouse in Nebraska
Grasslands in Nebraska, USA, face threats from agricultural conversion, urban development, and woody encroachment, all of which negatively affect prairie grouse (Tympanuchus spp.) populations. To optimize conservation planning, Nebraska wildlife agencies developed probabilistic area-based surveys for greater prairie-chicken (T. cupido) and sharp-tailed grouse (T. phasianellus) to sample...

Listening for extinction: Range-wide occupancy highlights critical risks and priorities for northern spotted owls Listening for extinction: Range-wide occupancy highlights critical risks and priorities for northern spotted owls
The northern spotted owl (Strix occidentalis caurina) continues to decline across its range, threatened by habitat disturbances and invasive barred owls (Strix varia). We conducted a range-wide spotted owl occupancy assessment using 2.1 million h of passive acoustic recordings from 4081 survey stations within 1027 randomly selected 5-km2 hexagons across six physiographic regions...
