Revised Distribution of the Alaska Marmot, Marmota Broweri, and Confirmation of Parapatry with Hoary Marmots

  title={Revised Distribution of the Alaska Marmot, Marmota Broweri, and Confirmation of Parapatry with Hoary Marmots},
  author={Aren M. Gunderson and Brandy K. Jacobsen and Link E. Olson},
Abstract The distribution and taxonomic status of the Alaska marmot (Marmota broweri) have been the subject of much debate and confusion since the taxon was 1st described as a subspecies of the hoary marmot (M. caligata). As a result of its early association with M. caligata and a lack of focused effort to determine its range, our current understanding of the distribution of M. broweri is vague at best and completely erroneous at worst. Through a review of all museum specimens and published… 
Current Understanding of the Alaska Marmot (Marmota broweri): A Sensitive Species in a Changing Environment
Increasing interest in mammalian species conservation necessitates synthesis of diffuse sources of information to supply useful synopsis to land managers. The Alaska Marmot ( Marmota broweri ) is
Marmot evolution and global change in the past 10 million years
Ground squirrels of the genus Marmota are known for their ability to tolerate bitterly cold climates, which they in part accomplish with their exceptional ability to hibernate for as much as eight
Marmota Caligata (Rodentia: Sciuridae)
Abstract Marmota caligata (Eschscholtz, 1829), a large ground squirrel commonly called the hoary marmot, is 1 of 15 species of extant marmots. It is distributed in western North America from Alaska
Limited phylogeographic structure and genetic variation in Alaska's arctic and alpine endemic, the Alaska marmot
Abstract Alpine and arctic environments are thought to be more vulnerable to climate change than other lower-elevation and lower-latitude regions. Being both arctic and alpine distributed, the Alaska
Contrasting consequences of historical climate change for marmots at northern and temperate latitudes
Many species that occupy high latitudes of North America were historically restricted to relatively small refugia during the Last Glacial Maximum (LGM). The geographic ranges of many of these species
Body temperature patterns during hibernation in a free-living Alaska marmot (Marmota broweri)
At least six animals emerged from the hibernaculum suggesting that communal hibernation may be a strategy to reduce metabolic costs while maintaining above-freezing Tb.
Comparative Phylogeography Highlights the Double-Edged Sword of Climate Change Faced by Arctic- and Alpine-Adapted Mammals
Similar phylogeographic histories are supported for all species, suggesting that these, and likely other, alpine- and arctic-adapted taxa are already experiencing population and/or range declines that are likely to synergistically accelerate in the face of rapid climate change.
Release date influences first‐year site fidelity and survival in captive‐bred Vancouver Island marmots
. Maximizing survival in reintroduced, captive- bred animals requires evaluation to identify best practices. This is particularly true for critically endangered species like the Vancouver Island mar
Inferring the geographic origin of a range expansion: Latitudinal and longitudinal coordinates inferred from genomic data in an ABC framework with the program x‐origin
A pipeline is developed for statistically inferring the geographic origin of range expansion using a spatially explicit coalescent model and an approximate Bayesian computation testing framework and is demonstrated with an analysis of genomic data collected in the Collared pika that underwent postglacial expansion across Alaska.


Cytogenetic evidence for the specific distinction of an Alaskan marmot, Marmota broweri Hall and Gilmore (Mammalia: Sciuridae)
It is concluded that the Brooks Range marmot is specifically distinct from M. caligata, the applicable name being Marmota broweriHall and Gilmore, and it is suggested that M. broweri survived the last (Wisconsin) glaciations in the amphi-Beringian refugium, and that its closest affinities may be with one of the Eurasian species of Marmot.
Molecular phylogeny of the marmots (Rodentia: Sciuridae): tests of evolutionary and biogeographic hypotheses.
These analyses reject the two major competing hypotheses of M. broweri's phylogenetic relationships--namely, that it is the sister species to M. camtschatica of eastern Siberia, and that it has a western montane clade in the Nearctic.

Patterns of morphological evolution in Marmota (Rodentia, Sciuridae): geometric morphometrics of the cranium in the context of marmot phylogeny, ecology and conservation
The Vancouver Island marmot had the most atypical ventral cranium in the subgenus Petromarmota, and emphasized the uniqueness of M. vancouverensis and the usefulness of complementing molecular analyses with morphological studies for a thorough characterization of population divergence, and a careful planning of conservation strategies.

Population cycles and changes in body size of the lynx in Alaska
It is found that skull size was negatively related to population size, and the density-dependent effect is probably due to changes in food supply, either resulting from the adverse effects of competition or a possible diminished availability of food.
Recent increase in body size of the American marten Martes americana in Alaska
The hypothesis that body size of the marten had increased during the second half of the 20th century, in response to global warming, was tested and it was found that skull size increased significantly, possibly due to an improved food supply and/or lower metabolic demands in winter.
Global warming, Bergmann's rule and body size in the masked shrew Sorex cinereus Kerr in Alaska
Summary 1. It was recently shown that body size of Palearctic shrews decreases with increasing latitude, thus contradicting Bergmann’s rule, and this trend was explained by food shortage during the
