Effect of population density on diet composition and dietary niche breadth of guanaco (Lama guanicoe, Müller 1776) in northeastern Patagonian steppes
(Elsevier, 2019-11)
The optimal foraging theory postulates that as animal population density increases, the progressive decline in preferred forage availability results in changes in diet composition and widening of dietary niche breadth. For ...
Response of pumas (Puma concolor) to migration of their primary prey in Patagonia
(Public Library of Science, 2017-12)
Large-scale ungulate migrations result in changes in prey availability for top predators and, as a consequence, can alter predator behavior. Migration may include entire populations of prey species, but often prey populations ...

Response of guanacos Lama guanicoe to changes in land management in Península Valdés, Argentine Patagonia: Conservation implications
(Cambridge University Press, 2012-01)
The guanaco Lama guanicoe was the only large native herbivore widely distributed across Patagonia until the introduction of domestic sheep Ovis aries. Guanacos have declined because of competition with sheep for forage, ...

Perinatal guanacos (Lama guanicoe) exploited by hunter‐gatherers from the Holocene of Argentine Pampas
(John Wiley and Sons Ltd, 2018-11-20)
The guanaco (Lama guanicoe) was the most relevant species in hunter-gatherer subsistence of the Argentine Pampas during the Quaternary. An early Late Holocene (3,184 ± 50 14C years bp) guanaco assemblage with evidence of ...
Criteria for the Identification of Formation Processes in Guanaco (Lama guanicoe) Bone Assemblages in Fluvial-Lacustrine Environments
(Prometheus Press, 2007-12)
The aim of this paper is to present and discuss methodological criteria that may be of use in exploring the role of water in the formation of the faunal record in fluvial and lacustrine environments. As such, the dispersion ...
Dung-pile use by guanacos in eastern Patagonia
(De Gruyter, 2018-11)
Previous studies on guanacos have reported that only territorial males create and maintain dung-piles. The aim of this analysis was to compare dung-pile use by territorial males with the use by females and young in family ...
