Multi-trophic occupancy modeling connects temporal dynamics of woodpeckers and beetle sign following fire Open
In conifer forests of western North America, wildlife populations can change rapidly in the decade following wildfire as trees die and animals respond to concomitant resource pulses that occur across multiple trophic levels. In particular,…

Modeling climate‐driven range shifts in populations of two bird species limited by habitat independent of climate Open
Ranges of species around the world are expected to contract in response to climate change. Species distribution models (SDMs) are a powerful tool for predicting changes in habitat availability, but the variables selected to create SDMs inf…

Demographic responses to climate‐driven variation in habitat quality across the annual cycle of a migratory bird species Open
The demography and dynamics of migratory bird populations depend on patterns of movement and habitat quality across the annual cycle. We leveraged archival GPS‐tagging data, climate data, remote‐sensed vegetation data, and bird‐banding dat…

Abiotic conditions shape spatial and temporal morphological variation in North American birds Open
Abiotic environmental conditions play a key role in driving the size and shape of organisms. Quantifying environment-morphology relationships is important not only for understanding the fundamental processes driving phenotypic diversity wi…

Concurrent Validity of Power From Three On-Water Rowing Instrumentation Systems and a Concept2 Ergometer Open
Purpose: Instrumentation systems are increasingly used in rowing to measure training intensity and performance but have not been validated for measures of power. In this study, the concurrent validity of Peach PowerLine (six units), Nielse…
View article: Conditional natal dispersal provides a mechanism for populations tracking resource pulses after fire
Conditional natal dispersal provides a mechanism for populations tracking resource pulses after fire Open
Animals that persist in spatially structured populations face the challenge of tracking the rise and fall of resources across space and time. To combat these challenges, theory predicts that species should use conditional dispersal strateg…

Relationships between measures of boat acceleration and performance in rowing, with and without controlling for stroke rate and power output Open
Purpose Boat acceleration profiles provide a valuable feedback tool by reflecting both rower technique and force application. Relationships between measures of boat acceleration and velocity to inform interpretation of boat acceleration pr…

Extent, configuration and diversity of burned and forested areas predict bat richness in a fire-maintained forest Open
Context Fire transforms, fragments and sometimes maintains forests, creating mosaics of burned and unburned patches. Highly mobile animals respond to resources in the landscape at a variety of spatial scales, yet we know little about their…

Patterns of woodboring beetle activity following fires and bark beetle outbreaks in montane forests of California, USA Open
Increasingly frequent and severe drought in the western United States has contributed to more frequent and severe wildfires, longer fire seasons, and more frequent bark beetle outbreaks that kill large numbers of trees. Climate change is e…

Nest site selection and nest survival of Black-backed Woodpeckers after wildfire Open
Recently burned coniferous forests host wildlife communities that respond to variation in burn severity, post-fire habitat structure, and patch configuration. Habitat selection theory predicts that birds inhabiting these variable post-fire…

Explaining the birds and the bees: deriving habitat restoration targets from multi‐species occupancy models Open
Riparian corridors can be highly biodiverse but are often degraded by human activities, and are therefore frequent targets of restoration actions. Yet managers often lack clear guidance on how to conserve or restore riparian vegetation str…
