Grizzly bears, black bears, wolves, coyotes, cougars/ mountain lions,bobcats, wolverines, lynx, foxes, fishers and martens are the suite of carnivores that originally inhabited North America after the Pleistocene extinctions. This site invites research, commentary, point/counterpoint on that suite of native animals (predator and prey) that inhabited The Americas circa 1500-at the initial point of European exploration and subsequent colonization. Landscape ecology, journal accounts of explorers and frontiersmen, genetic evaluations of museum animals, peer reviewed 20th and 21st century research on various aspects of our "Wild America" as well as subjective commentary from expert and layman alike. All of the above being revealed and discussed with the underlying goal of one day seeing our Continent rewilded.....Where big enough swaths of open space exist with connective corridors to other large forest, meadow, mountain, valley, prairie, desert and chaparral wildlands.....Thereby enabling all of our historic fauna, including man, to live in a sustainable and healthy environment. - Blogger Rick

Matt Cronin is a Research Professor of Animal Genetics at the University of Alaska Fairbanks................ He is co-author of the article ‘Single Nucleotide Polymorphism (SNP) Variation of Wolves (Canis lupus) in Southeast Alaska and Comparison with Wolves, Dogs, and Coyotes in North America’ which is published in the Journal of Heredity...........................His most current peer reviewed paper entitled ARE WOLVES ENDANGERED WITH EXTINCTION IN ALASKA was just published..................Matt focuses on whether the Alexander Archipelago Wolf in southeast Alaska is indeed a distinct species as defined by the U.S. Endangered Species Act............If in fact they are, then perhaps the Researchers seeking to put this Wolf on the endangered list have merit in their demands for this to happen................"The US Endangered Species Act (ESA) defines species as “species, subspecies, and distinct population segments”----"All of these categories are all considered “species” for the ESA"...................... "Although this definition is not consistent with the scientific definition of species it has become the legal definition of species for the ESA"..................Matt's conclusion is that "the overall pattern for wolves in southeast Alaska is not one of long term isolation and evolutionary independence and does not support a subspecies designation"............ "Other authors, including biologists with the US Fish and Wildlife Service, also do not designate wolves in southeast Alaska as a subspecies and there is general recognition that North America wolf subspecies designations have been arbitrary and are not supported by genetic data"...............Accordingly, Matt feels that other Scientists are erroneously looking to use "the sub species" category to place the southeast Alaska Wolves under the designation of the Endangered Species Act..............It will be interesting to see the rebuttals to Matt's conclusions and which "RESEARCH PARADIGM" will weigh heavy in the final determination of whether to give these Alaska Wolves Federal Protection or not

Are wolves endangered with extinction in Alaska?

Matt Cronin

Wolves in the panhandle of southeast Alaska are currently being considered as an endangered species by the US Fish and Wildlife Service in response to a petition by environmental groups. These groups are proposing that the Alexander Archipelago wolf (Canis lupus ligoni) subspecies that inhabits the entire region and a distinct population segment of wolves on Prince of Wales Island are threatened or endangered with extinction.




Whether or not these wolves are endangered with extinction was beyond the scope of our study. However our research quantified the genetic variation of these wolves in southeast Alaska which can contribute to assessing their status as a subspecies.
Because the US Endangered Species Act (ESA) defines species as “species, subspecies, and distinct population segments”, these categories are all considered “species” for the ESA. Although this definition is not consistent with the scientific definition of species it has become the legal definition of species for the ESA.
Therefore we have two questions to consider:
  • Are the wolves in southeast Alaska a subspecies?
  • Are the wolves on Prince of Wales Island a distinct population segment?
The literature on subspecies and distinct population segment designation is vast, but it is important to understand that subspecies is a taxonomic category, and basically refers to a group of populations that share an independent evolutionary history.
Taxonomy is the science of biological classification and is based on evolutionary history and common ancestry (called phylogeny). Species, subspecies, and higher-level groups (e.g, a genus such as Canis) are classified based on common ancestry. For example, wolves and foxes share common ancestry and are classified in the same family (Canidae), while bobcats and lions are classified in a different family (Felidae) because they share a common ancestry that is different from foxes and wolves.

Our results and other research showed that the wolves in Southeast Alaska differed in allele frequencies compared to wolves in other regions. Allele frequencies reflect the distribution of genetic variation within and among populations. However, the wolves in southeast Alaska do not comprise a homogeneous population, and there is as much genetic variation among the Game Management Units (GMU) in southeast Alaska as there is between southeast Alaska and other areas.
The overall pattern for wolves in southeast Alaska is not one of long term isolation and evolutionary independence and does not support a subspecies designation. Other authors, including biologists with the US Fish and Wildlife Service, also do not designate wolves in southeast Alaska as a subspecies and there is general recognition that North America wolf subspecies designations have been arbitrary and are not supported by genetic data.
There is growing recognition in the scientific community of unwarranted taxonomic inflation of wildlife species and subspecies designations to achieve conservation goals. Because the very nature of subspecies is vague, wildlife management and conservation should focus on populations, including wolf populations. This allows all of the same management actions as proposed for subspecies, but with increased scientific rigor.
