Spatial patterns of territorial large falcons influence mixed pair formation in an arid environment Open
Interspecific crossbreeding among breeding populations can lead to outbreeding depression and reduce individual fitness. Mixed pairs occur more frequently in areas with fragmented habitat where individual species often have low population …

Abundance of Long-billed Curlews on military lands in the Columbia Basin Open
Long-billed Curlews ( Numenius americanus ) are declining throughout North America, and the loss of grassland breeding habitat is one of the primary threats to the species. Intermountain West, in particular, has been identified as the most…

Strong migratory connectivity indicates Willets need subspecies-specific conservation strategies Open
By combining all available banding and tracking data, we found that Willets (Tringa semipalmata) have a strong migratory connectivity between breeding and nonbreeding locations at the range-wide and subspecies levels, exposing two subspeci…

Applying circuit theory and landscape linkage maps to reintroduction planning for California Condors Open
Conservation practitioners are increasingly looking to species translocations as a tool to recover imperiled taxa. Quantitative predictions of where animals are likely to move when released into new areas would allow managers to better add…

Changes in genetic diversity and differentiation in Red‐cockaded woodpeckers (<i>Dryobates borealis</i>) over the past century Open
Red‐cockaded woodpeckers (RCW; Dryobates borealis ) declined after human activities reduced their fire‐maintained pine ecosystem to <3% of its historical range in the southeastern United States and degraded remaining habitat. An estimated …

Isolation by distance versus landscape resistance: Understanding dominant patterns of genetic structure in Northern Spotted Owls (Strix occidentalis caurina) Open
Landscape genetics investigations examine how the availability and configuration of habitat influence genetic structure of plants and animals. We used landscape genetics to evaluate the role that forest connectivity plays in determining ge…

Variation in inbreeding rates across the range of Northern Spotted Owls (<i>Strix occidentalis caurina</i>): Insights from over 30 years of monitoring data Open
Inbreeding has been difficult to quantify in wild populations because of incomplete parentage information. We applied and extended a recently developed framework for addressing this problem to infer inbreeding rates in Northern Spotted Owl…

A simplified field protocol for genetic sampling of birds using buccal swabs Open
DNA sampling is an essential prerequisite for conducting population genetic studies. For many years, blood sampling has been the preferred method for obtaining DNA in birds because of their nucleated red blood cells. Nonetheless, use of bu…

Genetic differentiation and inferred dynamics of a hybrid zone between Northern Spotted Owls (<i>Strix occidentalis caurina</i>) and California Spotted Owls (<i>S. o. occidentalis</i>) in northern California Open
Genetic differentiation among Spotted Owl ( Strix occidentalis ) subspecies has been established in prior studies. These investigations also provided evidence for introgression and hybridization among taxa but were limited by a lack of sam…

Estimating Inbreeding Rates in Natural Populations: Addressing the Problem of Incomplete Pedigrees Open
Understanding and estimating inbreeding is essential for managing threatened and endangered wildlife populations. However, determination of inbreeding rates in natural populations is confounded by incomplete parentage information. We prese…

Polygamy slows down population divergence in shorebirds Open
Sexual selection may act as a promotor of speciation since divergent mate choice and competition for mates can rapidly lead to reproductive isolation. Alternatively, sexual selection may also retard speciation since polygamous individuals …

Ancient DNA reveals substantial genetic diversity in the California Condor (<i>Gymnogyps californianus</i>) prior to a population bottleneck Open
Critically endangered species that have undergone severe population bottlenecks often have little remaining genetic variation, making it difficult to reconstruct population histories to apply in reintroduction and recovery strategies. By u…
