Genetic variation in social mammals: the marmot model.
نویسندگان
چکیده
The social substructure and the distribution of genetic variation among colonies of yellow-bellied marmots, when analyzed as an evolutionary system, suggests that this substructure enhances the intercolony variance and retards the fixation of genetic variation. This result supports a traditional theory of gradual evolution rather than recent theories suggesting accelerated evolution in social mammals.

Evolutionary acceleration in the most endangered mammal of Canada: speciation and divergence in the Vancouver Island marmot (Rodentia, Sciuridae).
The Vancouver Island marmot is the most endangered mammal of Canada. Factors which have brought this population to the verge of extinction have not yet been fully elucidated, but the effects of deforestation and habitat fragmentation on survival rates, as well as those of variation in rainfall, temperature, snowpack depth and snowmelt strongly suggest that marmots on the island are struggling t...
متن کاملMarmots on Great Basin Mountaintops: Using Genetics to Test a Biogeographic Paradigm
Boreal mammals in the Great Basin have long been viewed as island-bound Pleistocene relicts because they occupy island-like patches of montane habitat separated by desert lowlands that presumably are impermeable to dispersal. Recent work, however, raised the possibility that dispersal among mountain ranges is an important process in the biogeography of boreal mammals in the Great Basin. We test...
متن کاملFecal Pellet Counts as a Technique for Monitoring an Alpine-Dwelling Social Rodent, the Hoary Marmot (Marmota caligata)
We evaluated fecal pellet counts as an index of hoary marmot (Marmota caligata) social group size in order to develop a simple, inexpensive method for monitoring population change of a widely distributed, but poorly studied alpine mammal. Fecal pellet counts were conducted in three separate seasons along several 2 m 3 100 m transects located parallel to and 10, 20, and 30 m from the edge of alp...
متن کاملFine-scale population genetic structure in a fission-fusion society.
Nonrandom patterns of mating and dispersal create fine-scale genetic structure in natural populations - especially of social mammals - with important evolutionary and conservation genetic consequences. Such structure is well-characterized for typical mammalian societies; that is, societies where social group composition is stable, dispersal is male-biased, and males form permanent breeding asso...
متن کاملSocial Variety in the Yellow-bellied Marmot : a Population-behavioural System
Rates of amicable and agonistic behaviour are not correlated either within or between two colonies of Marmota flaviventris nor is there any consistent pattern of rates being higher in one colony than in the other . Rates of social behaviour are related to population density, the age-sex structure of the population, the individual behavioural characteristics of the residents and potential recrui...
