Data from: High genomic diversity and candidate genes under selection associated with range expansion in eastern coyote (Canis latrans) populationsElizabeth Heppenheimer, Kristin E. Brzeski, Joseph W. Hinton, Brent R. Patterson, Linda Y. Rutledge, Alexandra L. DeCandia, Tyler Wheeldon, Steven R. Fain, Paul A. Hohenlohe, Roland Kays, Bradley N. White, Michael J. Chamberlain & Bridgett M. VonHoldt
Range expansion is a widespread biological process, with well described theoretical expectations for the genomic outcomes accompanying the colonization of novel ranges. However, comparatively few empirical studies address the genome-wide consequences associated with the range expansion process, particularly in recent or on-going expansions. Here, we assess two recent and distinct eastward expansion fronts of a highly mobile carnivore, the coyote (Canis latrans), to investigate patterns of genomic diversity and identify variants that may have been...
Data from: Population correlates of rapid captive-induced maladaptation in a wild fishDylan J. Fraser, Lisa Walker, Matthew C. Yates, Kia Marin, Jacquelyn L.A. Wood, Thais A. Bernos, Carol Zastavniouk & Jacquelyn L. A. Wood
Understanding the extent to which captivity generates maladaptation in wild species can inform species recovery programs and elucidate wild population responses to novel environmental change. Though rarely quantified, effective population size (Ne) and genetic diversity should influence the magnitude of plastic and genetic changes manifested in captivity that reduce wild fitness. Sexually-dimorphic traits might also mediate consequences of captivity. To evaluate these relationships, we generated >600 full- and half-sibling families from nine wild brook trout...
Data from: Geographic variation and environmental correlates of apparent survival rates in adult tree swallows Tachycineta bicolorRobert G. Clark, David W. Winkler, Russell D. Dawson, Dave Shutler, David J. T. Hussell, Michael P. Lombardo, Patrick A. Thorpe, Peter O. Dunn & Linda A. Whittingham
Determining demographic rates in wild animal populations and understanding why rates vary are important challenges in population ecology and conservation. Whereas reproductive success is reported frequently for many songbird species, there are relatively few corresponding estimates of annual survival for widespread populations of the same migratory species. We incorporated mark-recapture data into Cormack-Jolly-Seber models to estimate annual apparent survival and recapture rates of adult male and female tree swallows Tachycineta bicolor in eight local breeding...
Data from: Supplementation stocking of lake trout (Salvelinus namaycush) in small boreal lakes: ecotypes influence on growth and conditionOlivier Morissette, Pascal Sirois, Nigel P. Lester, Chris C. Wilson & Louis Bernatchez
Supplementation stocking is a commonly used management tool to sustain exploited fish populations. Possible negative consequences of supplementation on local stocks are a concern for the conservation of wild fish populations. However, the direct impacts of supplementation on life history traits of local populations have rarely been investigated. In addition, intraspecific hybridization between contrasting ecotypes (planktivorous and piscivorous) has been seldom considered in supplementation plans. Here, we combined genetic (genotype-by-sequencing analysis) and life history traits...
Data from: A range-wide domino effect and resetting of the annual cycle in a migratory songbirdElizabeth A. Gow, Lauren Burke, David W. Winkler, Samantha M. Knight, Robert G. Clark, Marc Bélisle, Lisha L. Berzins, Tricia Blake, Eli S. Bridge, Russell D. Dawson, Peter O. Dunn, Dany Garant, Geoff Holroyd, Andrew G. Horn, David J.T. Hussell, Olga Lansdorp, Andrew J. Laughlin, Marty L. Leonard, Fanie Pelletier, Dave Shutler, Lynn Siefferman, Caz M. Taylor, Helen Trefry, Carol M. Vleck, David Vleck … & D. Ryan Norris
Latitudinal differences in timing of breeding are well documented but how such differences carry over to influence timing of events in the annual cycle of migratory birds is not well understood. We examined geographic variation in timing of events throughout the year using light-level geolocator tracking data from 133 migratory tree swallows (Tachycineta bicolor) originating from 12 North American breeding populations. A swallow’s breeding latitude influenced timing of breeding, which then carried over to affect...
