Dietary overlap of coexisting exotic brown hare (Lepus europaeus) and endemic mara (Dolichotis patagonum) in Northern Patagonia (Mendoza, Argentina)
(De Gruyter, 2014-07)
Introduced brown hares are present across the distribution range of maras, which are endemic to Argentina’s open steppes. Food competition with exotic herbivores could be partially responsible for declines in mara populations. ...
Diet selection of the southern vizcacha (Lagidium viscacia): A rock specialist in north western Patagonian steppe, Argentina
(Polish Academy of Sciences, 2012-10)
The southern vizcacha (Lagidium viscacia) is a rock specialist that inhabits small colonies in isolated rocky outcrops of northwestern Patagonia. This study analyzes its diet selection in relation to food availability, ...
Seasonal diet of guanaco (Lama guanicoe) linked to vegetation life forms and environment types in Tierra del Fuego (Argentina)Dieta estacional de Lama guanicoe (Camelidae: Artiodactyla) en un paisaje heterogéneo de Patagonia Sur
(Univ Austral Chile, 2013-06)
Large diversity of habitat types, plant species assemblages, and silvopastoral activities in Nothofagus spp. forests condition the food availability for native herbivores. This work evaluates the seasonal diet of Lama ...
Ecological conditions and isotopic diet (13C and 15N) of Holocene caviomorph rodents in Northern Patagonia
(Academic Press Ltd - Elsevier Science Ltd, 2016-04)
This work improves our knowledge about the relationship between diet and environment among Northern Patagonian caviomorph rodents. In order to characterize long-term individual diets, we present δ13C and δ15N data from ...
Trophic interactions between two medium-sized mammals: the case of the native Dolichotis patagonum and the exotic Lepus europaeus in a hyper-arid ecosystem.
(Polish Acad Sciences, 2013-04)
As medium-sized herbivores, the exotic Lepus europaeus (European hare) and the native Dolichotis patagonum (mara) have been considered ecological equivalents. These species coexist in Ischigualasto Provincial Park, a ...
Trophic interactions between the native guanaco (Lama guanicoe) and the exotic donkey (Equus asinus) in the hyper-arid Monte desert (Ischigualasto Park, Argentina)
(Taylor & Francis Ltd, 2014-09)
Exotic herbivores have detrimental effects on the ecosystems where they are introduced, at the level of plant communities and ecosystem processes. The native guanaco Lama guanicoe and the exotic feral donkey Equus asinus ...
Dieta de Phytotoma rutila (Passeriformes: Cotingidae) en el desierto del Monte central, ArgentinaDiet of Phytotoma rutila (Passeriformes: Cotingidae) in the central Monte desert, Argentina
(Universidad de Concepción. Facultad de Ciencias Naturales y Oceanográficas, 2014-06)
Se determinó la composición botánica de la dieta del Cortarramas Phytotoma rutila en el desierto del Monte central, Argentina, mediante análisis microhistológico de las heces. En ambos sexos, la dieta estuvo compuesta por ...
Does food abundance determine the diet of the Puna Rhea (Rhea tarapacensis) in the Austral Puna desert in Argentina?
(Csiro Publishing, 2017-03)
The Puna Rhea (Rhea tarapacensis) is a large, flightless herbivorous bird found in the Andes Mountains of four countries, namely Argentina, Chile, Bolivia and Peru. Despite its ample distribution range, little is known ...
Flexibility in the food selection by the European hare (Lepus europaeus) along the altitudinal gradient of the Southern Andean Precordillera (Argentina)
(Springer, 2017-01)
Predictions derived from the optimal foraging theory are interesting to test on wild herbivores living in mountain environments, considering the expected vegetation changes across altitudinal gradients. A lower food richness ...
Diet of the brown hare (Lepus europaeus) and food availability in northern Patagonia (Mendoza, Argentina)
(Springer, 2007-07)
The brown hare, a Leporid widespread in the world, is now dispersed across Argentina after its introduction at the end of the 19th century. Studies on hare feeding ecology are important to evaluate a potential competition ...
