Predation risk and foraging behavior of the hoary marmot in Alaska [PDF]

open access: yesBehavioral Ecology and Sociobiology, 1984
I 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.

More functions of torpor and their roles in a changing world. [PDF]

open access: yesJ Comp Physiol B, 2017
Increased winter survival by reducing energy expenditure in adult animals is often viewed as the primary function of torpor. However, torpor has many other functions that ultimately increase the survival of heterothermic mammals and birds. In this review,

Can morphotaxa be assessed with photographs? Estimating the accuracy of two-dimensional cranial geometric morphometrics for the study of threatened populations of African monkeys. [PDF]

open access: yesAnat Rec (Hoboken), 2022
The classification of most mammalian orders and families is under debate and the number of species is likely greater than currently recognized. Improving taxonomic knowledge is crucial, as biodiversity is in rapid decline.

Helpers influence on territory use and maintenance in Alpine marmot groups [PDF]

open access: yes, 2015
In social mammals, territory size and shape vary according to the number and strength of neighbour individuals competing for resources. Two main theories have been proposed to explain this variability: the Group Augmentation (GA) and the realized ...

Ecogeographical Variation in Skull Shape of South-American Canids: Abiotic or Biotic Processes? [PDF]

open access: yes, 2015
Species morphological changes can be mutually influenced by environmental or biotic factors, such as competition. South American canids represent a quite recent radiation of taxa that evolved forms very disparate in phenotype, ecology and behaviour ...

Plant interactions are unimportant in a subarctic-alpine plant community [PDF]

open access: yes, 2009
We investigated whether plant interaction intensity in a subarctic-alpine meadow is important for determining community structure and species abundance.

Climate change and the conservation of marmots [PDF]

open access: yes, 2013
Conservation of marmots, large ground-dwelling squirrels restricted to the northern hemisphere, was impacted by direct human activity through hunting or modifying ecosystem dynamics. Regulating human activities reduced the threat of extinction.
