Chromosomes of fhe Northeastern American Woodchuk, Marmota monax were studied. Two animals had consistently a 2n value of 38 with 12 metacentric pairs. The Y-chromosome is the smallest element and it is submetacentric. Sex chromatin could not be identified with certainty in the histologic sections of all major organs.

The classification of the element here placed as No. 11 is difficult. In some preprations (top) it appears acrocentric, in others (bottom) it is more subtelocentric.

Cytogenetic evidence for the specific distinction of an Alaskan marmot, Marmota broweri Hall and Gilmore (Mammalia: Sciuridae)

TLDR
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.

Comparative karyology of Palearctic marmots (Marmota, Sciuridae, Rodentia)

TLDR
A combination of karyological and morphological data supports the distinction of all recognized Palearctic species of marmots adding to the list a new one, M. kastschenkoi, and a segregation of bobak and camtschatica species group is supported.

Analysis of the chromosomal abnormalities of a woodchuck hepatocellular carcinoma‐derived cell line (WH257GE10)

TLDR
The findings suggest that the chromosomal abnormalities found in WH257GE10 might be associated with the pathogenesis of woodchuck hepatocellular carcinoma.

Establishment and Characterization of a Woodchuck Hepatocellular Carcinoma Cell Line (WH44KA)

TLDR
The WH44KA cell line appears to be a useful in vitro model for the study of virus‐induced hepatocellular carcinoma and shows epithelial origin on light and electron microscopic examination.

Establishment of a new cell line from a woodchuck hepatocellular carcinoma

TLDR
T3‐HEP‐W1 is quite different from the previously reported WH257GE10 cell line and provides another in vitro model for the study of human hepatocellular carcinoma related to hepatitis B virus.

Complex History of Isolation and Gene Flow in Hoary, Olympic, and Endangered Vancouver Island Marmots

TLDR
A complicated history of rapid divergence of the 3 species followed by intermittent and possibly ongoing gene flow between hoary marmots and both Olympic and Vancouver Island marmot is suggested.

Seasonal changes in the adrenal glands of woodchucks (Marmota monax).

TLDR
There was a significant positive linear relationship between adrenal weight and body length and the initial rise in the spring corresponded to a period during which an increasing number of woodchucks were active for longer periods of time each day.

TLDR
Almost entirely rewritten, this edition provides an abundance of scientific information in combination with anecdotes, field notes, and an underlying reverence for the fragile diversity of animal life.

TLDR
This book presents a meta-anatomy of the woolly mammoth and some of the mechanisms that aid in the identification and characterization of these animals.
