摘要
. 智利中部大干旱期间culpeo fox Lycalopex culpaeus (Molina, 1782)的饮食:牛的作用和食肉哺乳动物之间高营养相互作用的证据。智利经历了自2010年以来持续的严重干旱。在此背景下,我们对智利地中海地区的Lycalopex culpaeus进行了营养研究,分析营养资源可用性的限制如何影响这些狐狸的饮食。通过对粪便的分析,我们可以观察到L. culpaeus以粪形动物为食,并以牛为食,可能是死牛。在研究期间,狐狸的活动没有变化。另一个有趣的方面是,全年都有食肉哺乳动物出现在粪便中;后者支持了在其他地区观察到的情况,即种间杀戮在食肉哺乳动物中很常见。

. Diet of culpeo fox Lycalopex culpaeus (Molina, 1782) during the mega-drought of central Chile: role of cattle and evidence of a high trophic interaction between carnivorous mammals. Chile has experienced a strong drought, which has been sustained since 2010. In this context, we conducted a trophic study for Lycalopex culpaeus , in the Chilean Mediterranean area, during this extreme climatic event to analyze how this phenomenon of restriction in the availability of trophic resources affects the diet of these foxes. The analysis of feces allows us to observe that L. culpaeus based its diet on lagomorphs and on the use of cattle, probably dead. During the study there was no change in foxes activity. Another interesting aspect was the sustained presence of carnivorous mammals in the feces throughout the year; the latter supports what has been observed in other regions, in that interspecific kills are common among carnivorous mammals.
期刊介绍:
Mastozoología neotropical = Journal of Neotropical Mammalogy, es una revista de periodicidad semestral, editada por la Sociedad Argentina para el Estudio de los Mamíferos. Esta es una sociedad interdisciplinaria cuyos principales objetivos son estimular y promover el desarrollo de la investigación científica, la publicación y la difusión de investigaciones sobre mamíferos actuales y/o fósiles, así como contribuir a la protección de la fauna de mamíferos de la región. Está dedicada a la publicación de artículos científicos originales, de opinión y revisiones de las variadas disciplinas que estudian a los mamíferos. Se especializa en mamíferos neotropicales.
