Rescue of a Severely Bottlenecked Wolf (Canis Lupus) Population by a Single Immigrant
Carles Vilà,Anna-Karin Sundqvist,Øystein Flagstad,Jennifer M. Seddon,Susanne Björnerfeldt,Ilpo Kojola,Adriano Casulli,Håkan Sand,Petter Wabakken,Hans Ellegren +9 more
TL;DR: It is shown here that the genetic diversity of the severely bottlenecked and geographically isolated Scandinavian population of grey wolves (Canis lupus), founded by only two individuals, was recovered by the arrival of a single immigrant.
Genomic consequences of intensive inbreeding in an isolated wolf population

TL;DR: Whole-genome resequencing of 97 grey wolves from a highly inbred population reveals complete homozygosity of entire chromosomes in many individuals and characterizes the genomic consequences of intensive inbreeding.
Genetic rescue in a severely inbred wolf population.
TL;DR: This study is one of the first to quantify and compare the reproductive success of first‐generation offspring from migrants vs. native, inbred individuals in a natural population and argues that inbreeding depression is the underlying mechanism for the profound difference in breeding success.

Colonization History and Noninvasive Monitoring of a Reestablished Wolverine Population
Øystein Flagstad,Eva Hedmark,Arild Landa,Henrik Brøseth,Jens Persson,Roy Andersen,Peter Segerström,Hans Ellegren +7 more
TL;DR: Bayesian analysis and subsequent assessment of individual relationships suggest that immigrants from northern Scandinavia have contributed and still contribute to the southern Norwegian gene pool, counteracting genetic erosion and reducing the risk of inbreeding depression.
Environmental change and rates of evolution: the phylogeographic pattern within the hartebeest complex as related to climatic variation
TL;DR: Observations strongly suggest that large–scale climatic fluctuations have been a major determinant for the species' evolutionary history and that hartebeest evolution has mainly taken place in isolated yet environmentally favourable refugia during periods of global warming.
