Data from: Potentially adaptive mitochondrial haplotypes as a tool to identify divergent nuclear loci

Michael R. Garvin, William D. Templin, Anthony J. Gharrett, Nick DeCovich, Christine M. Kondzela, Jeffrey R. Guyon & Megan V. McPhee
1. Genetic tools are commonly used for conservation and management of at-risk species. Individuals are often sampled from mixtures composed of many populations, which creates a need to assign individuals to their source. This can be problematic when the genetic divergence among source populations is weak but can be improved using adaptive genetic loci, which should show stronger levels of divergence. 2. We previously reported a signature of positive selection in the mitochondrial-encoded ND5 subunit...

The sustained exploitation of marine populations requires an understanding of a species' adaptive seascape so that populations can track environmental changes from short- and long-term climate cycles and from human development. The analysis of the distributions of genetic markers among populations, together with correlates of life-history and environmental variability, can provide insights into the extent of adaptive variation. Here, we examined genetic variability among populations of mature European anchovies (n = 531) in the Adriatic...

Data from: Potential of environmental DNA to evaluate Northern pike (Esox lucius) eradication efforts: an experimental test and case study

Kristine J. Dunker, Adam J. Sepulveda, Robert L. Massengill, Jeffrey B. Olsen, Ora L. Russ, John K. Wenburg & Anton Antonovich
Determining the success of invasive species eradication efforts is challenging because populations at very low abundance are difficult to detect. Environmental DNA (eDNA) sampling has recently emerged as a powerful tool for detecting rare aquatic animals; however, detectable fragments of DNA can persist over time despite absence of the targeted taxa and can therefore complicate eDNA sampling after an eradication event. This complication is a large concern for fish eradication efforts in lakes since killed...

Data from: Interactions between demography, genetics, and landscape connectivity increase extinction probability for a small population of large carnivores in a major metropolitan area

John F. Benson, Peter J. Mahoney, Jeff A. Sikich, Laurel E.K. Serieys, John P. Pollinger, Holly B. Ernest, Seth P.D. Riley, Laurel E. K. Serieys & Seth P. D. Riley
The extinction vortex is a theoretical model describing the process by which extinction risk is elevated in small, isolated populations owing to interactions between environmental, demographic, and genetic factors. However, empirical demonstrations of these interactions have been elusive. We modelled the dynamics of a small mountain lion population isolated by anthropogenic barriers in greater Los Angeles, California, to evaluate the influence of demographic, genetic, and landscape factors on extinction probability. The population exhibited strong survival...

Data from: Genetic profiling links changing sea-ice to shifting beluga whale migration patterns

There is increasing concern over how Arctic fauna will adapt to climate related changes in sea-ice. We used long-term sighting and genetic data on beluga whales (Delphinapterus leucas) in conjunction with multi-decadal patterns of sea-ice in the Pacific Arctic to investigate the influence of sea-ice on spring migration and summer residency patterns. Substantial variations in sea-ice conditions were detected across seasons, years and sub-regions, revealing ice–ocean dynamics more complex than Arctic-wide trends suggest. This variation...
