TLDR
Red deer introduced to Argentina now occur in extensive areas of Patagonia, and their distribution overlaps partially with that of the guanaco, which raises the possibility that feeding competition exists, particularly as the floristic diversity is very low.Abstract:
Das in Argentinien eingefuhrte Rotwild besiedelt derzeit grose Gebiete von Patagonien. Das Verbreitungsgebiet uberschneidet sich teilweise mit der Verbreitung der einheimischen Kamelart Guanaco. Die vorliegende Mitteilung beschreibt direkte Beziehungen zwischen den beiden Arten in einem Okotongebiet des Nahuel Huapi Nationalparks. Beide Arten wurden oft zusammen beim Asen an gleichen Orten und zur gleichen Zeit beobachtet, und die Distanz zwischen Individuen beider Arten war z. T. weniger als ein Meter. Dadurch entsteht die Moglichkeit, das es zur Futterkonkurrenz kommt, vor allem da die floristische Artenvielfalt sehr gering ist. Zudem konnte diese Vertraglichkeit des Verhaltens die Epidemiologie verschiedener Krankheiten beider Arten beeinflussen. Obwohl Gruppen von Guanacos ihr Territorium gegen andere Gruppen verteidigen, akazeptieren sie Gruppen von Rotwild, ohne Aggressivitat zu zeigen.read more

The current distribution of red deer (Cervus elaphus) in southern Latin America
TL;DR: In this article, the authors provided the current distribution of red deer in Chile and Argentina with respect to habitat types to permit informed decisions to manage the invasion, which will have direct consequences for the native biodiversity and conservation efforts.

Potential existence of a sylvatic cycle of Taenia ovis krabbei in Patagonia, Argentina.
Werner T. Flueck,A. Jones +1 more
TL;DR: In this article, the authors report on the possible occurrence of Taenia ovis krabbei established in a sylvatic cycle in Patagonia and show that hook characters, size, appearance, and location of a cysticercus from a wild red deer are consistent with Taena ovis ovis or T. ovis.

Diet of Guanaco and Red Deer in Neuquen Province, Argentina
TL;DR: In this paper, the spring and summer diets of guanaco (Lama guanicoe) and red deer (Cervus elaphus) in northern Patagonia were determined by the microhistological analysis of their droppings.
