Abstract
espanolEl fuego es un importante agente perturbador en varios ecosistemas de todo el mundo que puede afectar a la disponibilidad de recursos en una zona determinada, regulando la interaccion entre especies competidoras. Estudiamos la dieta del zorro culpeo (Lycalopex culpaeus) y el puma (Puma concolor) por dos anos consecutivos en un zona protegida del centro y el sur de Chile que se vio afectada por un incendio forestal. Se observaron diferencias significativas en el regimen alimentario de ambas especies, lo que pone de manifiesto su segregacion trofica. En los dos anos del estudio, la presa predominante del puma fue una especie exotica: la liebre europea (Lepus europaeus), lo que sugiere una simplificacion de su espectro trofico respecto a lo reportado en otras latitudes. Se analizan las consecuencias ecologicas de este hecho. EnglishFire is a significant disruptive agent in various ecosystems around the world. It can affect the availability of resources in a given area, modulating the interaction between competing species. We studied the diet of the culpeo fox (Lycalopex culpaeus) and cougar (Puma concolor) for two consecutive years in a protected area of southern–central Chile which was affected by a wildfire. Significant differences were observed in the dietary pattern between the two species, showing their trophic segregation. In the two years of the study, the predominant prey for cougar was an exotic species, the European hare (Lepus europaeus), implying a simplification of its trophic spectrum with respect to that reported in other latitudes. The ecological consequences related to this scenario are discussed.
西班牙火是世界各地许多生态系统的主要干扰因素，它可以影响特定地区的资源可用性，调节竞争物种之间的相互作用。在智利中部和南部受森林火灾影响的保护区，我们连续两年研究了culpeo fox (Lycalopex culpaeus)和puma concolor的饮食。在本研究中，我们观察到两个物种的饮食有显著差异，表明它们的营养分离。在两年的研究中，美洲狮的主要猎物是一种外来物种:欧洲野兔(Lepus europaeus)，这表明与其他纬度报道的相比，美洲狮的营养谱有所简化。分析了这一事件的生态后果。英国火是世界各地各种生态系统的重要破坏者。它可以影响特定地区资源的可用性，调节竞争物种之间的相互作用。在智利中南部受野火影响的保护区，我们连续两年研究了culpeo fox (Lycalopex culpaeus)和cougar (Puma concolor)的饮食。这两个物种的饮食模式有显著差异，显示出它们的营养分离。In the two》of the study, predominant prey for美洲狮was an exotic species,欧洲野兔(Lepus europaeus) implying简化of its trophic累计In other纬度spectrum with respect to that。这一情景的生态后果正在讨论中。
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
