SummaryPredictions were made and tested, comparing the foraging behavior of reproductive (rf) and nonreproductive (nrf) female hoary marmots, with the following findings: In June, no differences occur between rf's and nrf's, regarding daytime foraging. However, rf's forage more in the evening and during inclement weather, suggesting that greater nutritional needs and higher reproductive value select for the assumption of more risk while foraging. These differences disappear by August, when… 
Predation risk and foraging behavior of the hoary marmot in Alaska

It is suggested that food and predation risk jointly influence patch use by hoary marmots and that both factors must be considered when modeling the foraging behavior of species that can be predator and prey simultaneously.
Pastoralist disturbance effects on Himalayan marmot foraging and vigilance activity
Pastoralism is pervasive and has a long history across the rangelands of Trans-Himalaya. Disturbance associated with pastoralism can influence the behaviour of wild animals; hence, it is important to
The overall wariness strategy of marmots is to spend time near the burrow to assess potential risk before initiating foraging and various interactions among season, time of day, location, and animal group indicate adjustment of the time budget to prevailing conditions.
Temporal shift in activity patterns of Himalayan marmots in relation to pastoralism
To investigate the extent to which disturbances associated with pastoralism changed the timing of foraging and activity patterns of Himalayan marmot, a widely distributed rodent that inhabits alpine meadows in the mountains of central Asia, an index of pastoralism intensity was developed based on the presence of livestock, herders, guard dogs, distance from pastoralist camps, and density of major tracks.
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
Reproductive rates of wild and captive Vancouver Island marmots (Marmota vancouverensis)
It is concluded that reproductive performance in Vancouver Island marmots is limited both by body condition and social constraints.
Sociality of Columbian ground squirrels in relation to their seasonal energy intake
It is suggested that “harsh” environments reduce the energy available for juvenile growth and development, leading to delayed dispersal and age at first reproduction, and may promote the formation of kin groups and increased amicable interactions within those groups.
Seasonal changes in the time budget of degus, Octodon degus
It is hypothesized that breeding activity is a more important predictor than abundance of high quality food to account for these interactions in degus, a diurnal, semi-subterranean and social rodent from central Chile.
Fecal Pellet Counts as a Technique for Monitoring an Alpine-Dwelling Social Rodent, the Hoary Marmot (Marmota caligata)
Fecal pellet counts appear to provide a precise index of marmot group size suitable for long-term monitoring of population change of a widely distributed, but poorly studied alpine mammal.
Ecological, Evolutionary and Social Constraints on Reproductive Effort: Are Hoary Marmots Really Biennial Breeders?
Hoary marmots are less conservative breeders than previously believed, and the evidence for biennial breeding throughout Marmota, and in other arctic/alpine/antarctic animals, should be re-examined.


Socioecology of Marmots: Female Reproductive Strategies
The relationship between female reproductive success and both spring food and hibernacula resources was examined in a high-altitude population of yellow-bellied marmots (Marmota flaviventris). The

Optimal Foraging: A Selective Review of Theory and Tests
The general conclusion is that the simple models so far formulated are supported are supported reasonably well by available data and that the author is optimistic about the value both now and in the future of optimal foraging theory.
Theory of Feeding Strategies
Throughout, emphasis will be placed on strategic aspects of feeding rather than on what Holling (75) has called "tactics," and possible answers to the first problem may be given to the second problem.
An Analysis of Diet Selection by Large Generalist Herbivores

A property of this "optimization model" is that the contribution of a food to the diet will sometimes vary with the food's content of a particular nutrient and sometimes will not, which might explain why no consistent relations of this kind have been found experimentally.

The Genetical Theory of Natural Selection
Although it is true that most text-books of genetics open with a chapter on biometry, closer inspection will reveal that this has little connexion with the body of the work, and that more often than not it is merely belated homage to a once fashionable study.
