Abstract

espanolLas bellotas del genero Quercusson muy apreciadas por diversos animales. Se ha cuestionado si la seleccion de una bellota puede depender de las caracteristicas intrinsecas del fruto. En este trabajo determinamos si el tamano y la calidad de las bellotas (sanas o danadas) influyen en su seleccion. Los resultados muestran que Q. affinisfue la especie con las bellotas mas grandes, pero con la tasa mas baja de seleccion, y que Q. eduardiitenia bellotas mas pequenas, pero con la tasa mas alta de seleccion. La seleccion la llevan a cabo dos grupos de vertebrados con periodos de actividad claramente separados. Los arrendajos Aphelocoma spp. realizaban su actividad de dia y los roedores Peromyscus spp., de noche. El tamano y la calidad solo representaron una influencia significativa en la seleccion de bellotas de Q. affinis. Nuestros resultados sugieren que la ausencia de animales grandes puede poner en riesgo el establecimiento de especies con bellotas grandes (como Q. affinis). EnglishAcorns of the species of the genus Quercus are highly appreciated by a diverse group of animals. It remains unclear whether the choice to move an acorn is related to the intrinsic characteristics of the fruit. In this work, we aimed to determine whether the size and quality of acorns (healthy or damaged) influenced their removal. We found that Q. affinis was the species with the largest acorns but the lowest removal rate, and Q. eduardii was the species with the smallest acorns but highest removal rates. Two groups of vertebrates carried out this removal, and this activity occurred at two clearly separate times. Jays Aphelocoma spp. carried out their activity during the day, and rodents Peromyscus spp. removed acorns at night. Size and quality only had a significant influence on the removal of Q. affinis. Our results suggest that absence of large animals could put the establishment of species with large acorns (such as Q. affinis) at risk.

在墨西哥中北部的栎树林中，食粒动物对橡子大小和质量的偏好

Quercusson属的橡子，深受各种动物的喜爱。人们质疑橡子的选择是否取决于果实的内在特征。在本研究中，我们确定橡子的大小和质量(健康或受损)是否影响其选择。结果表明，该物种的亲和力最大，但选择率最低，而eduardiitenia的亲和力较小，但选择率最高。选择是由两组活动周期明显不同的脊椎动物进行的。松鼠在白天活动，啮齿动物在晚上活动。在本研究中，我们分析了两种不同类型的橡子的选择。我们的研究结果表明，大型动物的缺乏可能会威胁到大型橡子物种(如affinis)的建立。= =地理= =根据美国人口普查，该地区的总面积为，其中土地和(0.964平方公里)水。这仍然是一个举措是否the choice to move an acorn is related to the intrinsic水果的特征。在这项工作中，我们试图确定橡子的大小和质量(健康或损坏)是否影响其移除。We found that was the species with the largest q . affinis acorns but the最低removal rate was, and q . eduardii the species with the smallest acorns的but removal房费。= =地理= =根据美国人口普查，这个县的总面积为，其中土地和(0.984平方公里)水。= =地理= =根据美国人口普查，这个县的土地面积为。= =地理= =根据美国人口普查，这个县的总面积为，其中土地和(1.5%)水。Our成果suggest that of large动物可put the establishment of species with large acorns(如:q . affinis) at risk。

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.
