SummaryI observed hoary marmots for three field seasons to determine how the distribution of food and the risk of predation influenced marmots' foraging behavior. I quantified the amount of time Marmota caligata foraged in different patches of alpine meadows and assessed the distribution and abundance of vegetation eaten by marmots in these meadows. Because marmots dig burrows and run to them when attacked by predators, marmot-toburrow distance provided an index of predation risk that could be… 
Do Yellow-Bellied Marmots Perceive Enhanced Predation Risk When they are Farther from safety? An experimental study
Yellow-bellied marmot (Marmota flaviventris) antipredator behavior is conducted, demonstrating that marmots’ perceptions of risk increased with distance to the burrow and decreased when other individuals were within 10 m of them while they foraged.
Alpine marmots (Marmota marmota) adjust vigilance behaviour according to environmental characteristics of their surrounding
The results suggest that Alpine marmots adjust vigilance behaviour according to the environmental characteristics of their surroundings while there appears to exist an optimal duration of scan bouts which is independent of relative predation risk.
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.
Although suitable marmot habitat is continuous at this site, marmot food plants were distributed in clumps and areas in which marmots concentrated their foraging contained a disproportionate amount of clover compared with its abundance in the study site.
Foraging decisions of North American beaver (Castor canadensis) are shaped by energy constraints and predation risk
It is likely that the observation that foraging was the most intense close to shore is due to energetic constraints, however, predation risk probably affects the decision whether to forage on the land in the first place.
Foraging efficiency of Akodon azarae under different plant cover and resource levels
It is concluded that A. azarae appears to maximize its consumption depending on predation risk, and has a greater foraging efficiency in safe areas than in risky ones.
Burrowing and Anti-Predator Requirements Determine the Microhabitat Selection of Himalayan Marmot in Zoige Wetland
It is shown that to explore how the animals survive in an environment, it is important to conduct the analysis at multiple scales, and patches characterized by flat ground and low soil moisture content, with medium vegetation standing height and low vegetation density are selected in the Zoige wetland.
Survival and antipredator behavior of woodchucks (Marmota monax) along an urban-agricultural gradient
This research examined spatial heterogeneity in real and perceived risk across an urbanization gradient by comparing survival rates, causes of mor- tality, and antipredator behavior of adult woodchucks within an agricultural landscape in Ill- nois from 2007 to 2009.
Habitat characteristics of the hoary marmot: assessing distribution limitations in Montana
Species that live in ecosystems with extremely different seasonal conditions must balance the constraints of each season to survive. Alpine species that do not migrate seasonally are especially adept
Age and seasonal effects on predator‐sensitive foraging in squirrel monkeys (Saimiri sciureus): a field experiment

Results indicate that age and local resource availability based on seasonality affect whether primates forage in a predator‐sensitive manner, and juveniles may be more sensitive to predation risk when foraging, and individuals may take fewer risks when resource abundance is high in their environment.


Behavioral ecology of alpine yellow-bellied marmots
Environmental parameters, population dynamics, resource utilization patterns, and social dynamics were evaluated in terms of their relationships to population density, intraspecific competition, parent—offspring relations, and male territoriality.
Foods of the Hoary Marmot on Kenai Peninsula, Alaska
The marmot populations from different mountains had similar diet-habitat characteristics even though less plant biomass was available in 1972 than in 1971 on two of three alpine study areas.
Predation and Risk in Foraging Minnows: Balancing Conflicting Demands
The patch choice model is proposed as a working hypothesis that relates net energy intake to time spent in patches where predators, if present, reduce time spent foraging by their prey, and predicts that the relative benefit of high food patches is independent of the presence of predators.
The Social Biology of the Olympic Marmot
Influence of a predator on the optimal foraging behaviour of sticklebacks (Gasterosteus aculeatus L.)
Three-spined sticklebacks' foraging behaviour changes such that they attack swarm regions of lower density which provide a lower feeding rate but should increase their ability to detect an approaching predator, predicted by a model using Pontryagin's principle of maximisation.
Social behaviour of a colony of the yellow-bellied marmot ()
An Experimental Test of the Effects of Predation Risk on Habitat Use in Fish
Methods to predict the additional mortality expected on a cohort due to a reduction in growth rate are developed, and the potential for predation risk to enforce size—class segregation is discussed, which leads de facto to resource partitioning.
Demography of Yellow‐Bellied Marmont Populations
Marmot (Marmota flaiiventris) populations are colonial or satellite. The num- ber of adults of colonial populations is relatively stable; fluctuations occur primarily because of changes in numbers of
Foraging Strategies and the Avoidance of Predation by an Aquatic Insect, Notonecta Hoffmanni
The degree of avoidance is related to the risk of predation and the possibility that feeding behavior represents an adaptive compromise between the conflicting demands of feeding efficiently and avoiding predators is discussed, and the effects on the predictions of optimal foraging theory of some common mecha- nisms by which notonectids avoid their predators are discussed.
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
