Les habitudes alimentaires des cabiais et du betail vivant dans la region non insulaire du bas delta du Parana ont ete etudiees. De plus, des echantillons de ragondins ont egalement ete etudies, egalement par analyse microhistologique des feces. Des echantillons de feces ont ete collectes saisonnierement pendant 2 ans, entre 1991 et 1993. Les resultats ont montre que les Poaceae etaient le principal groupe consomme tout au long de l'annee, a la fois par les cabiais et le betail, a l'exception… Expand

Capybaras (Rodentia: Cavidae) in highlands: environmental variables related to distribution, and herbivory effects on a common plant species
TLDR
The results show that capybaras frequently occur in the high-altitude grasslands along the Campo Belo River, but they avoid waterlogged areas, suggesting that in highlands the species may present different environmental preferences from those presented in lowlands. Expand
Forage use in domestic cattle (Bos indicus), capybara (Hydrochoerus hydrochaeris) and pampas deer (Ozotoceros bezoarticus) in a seasonal Neotropical wetland
TLDR
The presence of cattle does not appear to be as detrimental to wild herbivores as suggested by other examples in the literature and diets were more similar between the species during the wet season than during the dry season. Expand
Diets of plains vizcacha, greater rhea and cattle in Argentina.
TLDR
Similarities between the diets of plains vizcacha and cattle seem to support the ranchers' view that vizcachas compete with domestic herbivores for forage, however, high overlap in food habits would result in competition only if forage is scarce. Expand
Feeding habits of capybaras (Hydrochoerus hydrochaeris, Linnaeus 1766), in the Ecological Reserve of Taim (ESEC - Taim) - south of Brazil
TLDR
Capybaras from the ESEC-Taim varied diet according to the season and alimentary availability, and showed an opportunistic behavior in the winter and summer and a more selective behavior in spring and fall. Expand
Rango de Hogar y uso de Hábitat de Carpinchos en Pastizales recién invadido en el Chaco Seco de Paraguay
Results: The results show that the average home range of capybaras was 183 ha, similar to reported home ranges of capybaras in the Brazilian Pantanal. Within the study area, capybaras used andExpand
Influence of livestock grazing on the capybara’s trophic niche and forage preferences
TLDR
Changes in availability of foraging species may influence the capybara’s preference patterns and the consumption of suboptimal feeding items may indicate a greater pressure on foraging resources in the areas where capybaras share their habitat with livestock. Expand

HABITAT, THE TEMPLET FOR ECOLOGICAL STRATEGIES?
TLDR
In this Address, the author will attempt some quantification, but will not be able to emulate those former Presidents who have been able to provide a definitative synthesis of a field or of their own studies, and his offering can be but a small beginning, an indication of the type of characteristics the authors should quantify.

INFLUENCE OF THE BIOMASS, BOTANICAL COMPOSITION AND SWARD HEIGHT OF ANNUAL PASTURES ON FORAGING BEHAVIOUR BY SHEEP
TLDR
It is shown that sheep grazing a pasture which varies spatially in biomass will tend to graze it to a uniform biomass by concentrating their grazing on areas with the highest yield, however, selection of species will occur particularly when there are several species present. Expand
Forging at Different Spatial Scales: Dorcas Gazelles Foraging for Lilies in the Negev Desert
TLDR
Congruent with optimal foraging predictions, the gazelles selected plants with more and larger leaves than randomly available, and concentrated their foraging activity in areas of highest lily densities, and there was a surprising negative correlation between the size of the plant and the amount eaten.

TLDR
It is indicated that the bite-count and fecal analysis methods give similar results for estimating major components of cattle diets in Texas and microscopic evaluation of diets from fecal material seems to offer a viable choice. Expand
