Isolation and characterization of microsatellite loci in merlins (Falco columbarius) and cross-species amplification in gyrfalcons (F. rusticolus) and peregrine falcons (F. peregrinus)
Merlins, Falco columbarius, breed throughout temperate and high latitude habitats in Asia, Europe, and North America. Like peregrine falcons, F. peregrinus, merlins underwent population declines during the mid-to...

Mitochondrial genome diversity and population mitogenomics of polar cod (Boreogadus saida) and Arctic dwelling gadoids
High-latitude fish typically exhibit a narrow thermal tolerance window, which may pose challenges when co** with temperatures that shift outside of a species’ range of tolerance. Due to its role in aerobic m...

Small-scale genetic structure in an endangered wetland specialist: possible effects of landscape change and population recovery
The effects of anthropogenic landscape change on genetic population structure are well studied, but the temporal and spatial scales at which genetic structure can develop, especially in taxa with high dispersa...

Monitoring the Welfare of Polar Bear Populations in a Rapidly Changing Arctic
Most programs for monitoring the welfare of wildlife populations support efforts aimed at reaching discrete management objectives, like mitigating conflict with humans. While such programs can be effective, th...

Genetic structure and viability selection in the golden eagle (Aquila chrysaetos), a vagile raptor with a Holarctic distribution
Molecular markers can reveal interesting aspects of organismal ecology and evolution, especially when surveyed in rare or elusive species. Herein, we provide a preliminary assessment of golden eagle (Aquila chrys...

Spatial genetic structure of bristle-thighed curlews (Numenius tahitiensis): breeding area differentiation not reflected on the non-breeding grounds
Migratory birds occupy geographically and ecologically disparate areas during their annual cycle with conditions on breeding and non-breeding grounds playing separate and important roles in population dynamics...

Development and characterization of microsatellite markers for the Hawaiian coot, Fulica alai, and Hawaiian gallinule, Gallinula galeata sandvicensis, through next-generation sequencing
We used next generation shotgun sequencing to develop novel microsatellite markers for two endangered waterbirds; the Hawaiian coot (Fulica alai) and Hawaiian gallinule (Gallinula galeata sandvicensis). The 20 lo...

Interspecific hybridization contributes to high genetic diversity and apparent effective population size in an endemic population of mottled ducks (Anas fulvigula maculosa)
Under drift-mutation equilibrium, genetic diversity is expected to be correlated with effective population size (N e ). Changes in population size and gene flow ...

Spatial variation and low diversity in the major histocompatibility complex in walrus (Odobenus rosmarus)
Increased global temperature and associated changes to Arctic habitats will likely result in the northward advance of species, including an influx of pathogens novel to the Arctic. How species respond to these...

Identification of metapopulation dynamics among Northern Goshawks of the Alexander Archipelago, Alaska, and Coastal British Columbia
Northern Goshawks occupying the Alexander Archipelago, Alaska, and coastal British Columbia nest primarily in old-growth and mature forest, which results in spatial heterogeneity in the distribution of individ...
