Extreme inbreeding likely spells doom for Isle Royale wolves
Apr 18, 2016 · Since 1958, researchers have tracked the fate of wolves and their moose prey on the island, a U.S. national park and wilderness area, in the world's longest running predator-prey study, a staple of ecology textbooks . The National Park Service (NPS) today released the annual report of the Isle Royale predator-prey study, now in its 58th year.
Genomic signatures of extensive inbreeding in Isle Royale wolves, …
To characterize the genome-wide effects of intense inbreeding and isolation, we performed whole-genome sequencing and morphological analysis of an iconic inbred population, the gray wolves (Canis lupus) of Isle Royale.
Genomic consequences of intensive inbreeding in an isolated wolf ...
Nov 20, 2017 · We used whole-genome resequencing of 97 grey wolves (Canis lupus) from the highly inbred Scandinavian wolf population to identify ‘identical-by-descent’ (IBD) chromosome segments as runs of...
Genomics of Isle Royale Wolves Reveal Impacts of Inbreeding
May 29, 2019 · A new paper explores the genetic signatures of extreme inbreeding in the Isle Royale wolf population that led to its ultimate collapse, leaving just a single pair of non-reproductive old wolves. The pair are father-daughter and share the same mother.
Extra ribs, crooked backs show inbreeding that caused Isle ... - mlive
May 29, 2019 · ISLE ROYALE, MI - While there were many factors that played into Isle Royale’s once-robust wolf pack system collapsing to just two wolves in the space of a decade, a new study shows just how...
Inbreeding in Scandinavian wolves is worse than we thought
Dec 2, 2017 · Swedish, Norwegian and American researchers have now joined forces to conduct a detailed genetic study to see exactly how inbred the Scandinavian wolves are. The study, which relied on DNA from nearly 100 wolves, was recently published in the journal Nature Ecology & …
Genetic rescue in a severely inbred wolf population - PMC
Sep 6, 2016 · Highly inbred wolves may have lower survival during natal dispersal as well as competitive disadvantage to find a partner. Our 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.
Inbreeding in Island Wolves - BioInteractive
Jun 5, 2023 · Inbred offspring may have genetic conditions that reduce their ability to survive and reproduce, which is called inbreeding depression. This study examined the wolves of Isle Royale, a small island population with significant inbreeding depression.
Structural genomic variation in the inbred Scandinavian wolf …
Feb 7, 2024 · The arrival and integration of two eastern wolves into the Scandinavian population counteracted inbreeding, decreased the realized genetic load, and reintroduced ancestral alleles at loci that had become fixed for the derived allele in the population.
Jan 9, 2016 · We evaluated the extent of inbreeding and inbreed-ing depression in a small, re-introduced population of red wolves ( rufus) in Canis North Carolina. Since red wolves were first re-introduced in 1987, pedigree inbreeding coefficients ( increased considerably and almost every wild born wolf was inbred. 0.154 and max 0.383).
