Abstract

Abstract I investigated behavioral niche partitioning in two morphologically similar and sympatric Emblyna spiders by collecting webs of Emblyna francisca and Emblyna reticulata from Sambucus and Atriplex plants at the Panorama Vista Preserve in Kern County, California. I measured web heights and identified prey found in webs to compare web placement and prey distributions in each habitat. Emblyna francisca webs contained more prey than did E. reticulata webs in both habitats. The two spiders had similar abundance in Atriplex, but in Sambucus, E. reticulata was more abundant than E. francisca. Emblyna reticulata placed its webs higher than E. francisca in Atriplex but not in Sambucus, and the distribution of prey in webs differed between the two spiders in Sambucus, but not in Atriplex.

方济各和网纹EMBLYNA的行为生态位划分

摘要我通过在加利福尼亚州科恩县全景维斯塔保护区收集Sambucus和Atriplex植物中的Emblyna francisca和Emblyna reticulata的网，研究了两种形态相似且同域的Emblynna蜘蛛的行为生态位划分。我测量了网的高度，并确定了在网中发现的猎物，以比较每个栖息地的网的位置和猎物的分布。在这两个栖息地，方济各Emblyna网中的猎物都比网状网中的E.reticulata网多。这两种蜘蛛在Atriplex中的数量相似，但在Sambucus中，网状网蛛的数量比方济各蛛的数量更多。网状Emblyna reticulata在Atriplex的蜘蛛网比E.francisca高，但在Sambucus没有。Sambucus的两种蜘蛛网中猎物的分布不同，但在Atriplex没有。

期刊介绍： The Southwestern Naturalist (a publication of the Southwestern Association of Naturalists since 1953) is an international journal (published quarterly) that reports original and significant research in any field of natural history. This journal promotes the study of plants and animals (living and fossil) in the multinational region that includes the southwestern United States, Mexico, and Central America. Appropriate submission of manuscripts may come from studies conducted in the countries of focus or in regions outside this area that report significant findings relating to biota occurring in the southwestern United States, Mexico, and Central America. Publication is in English, and manuscripts may be feature articles or notes. Feature articles communicate results of completed scientific investigations, while notes are reserved for short communications (e.g., behavioral observations, range extensions, and other important findings that do not in themselves constitute a comprehensive study). All manuscripts (feature articles and notes) require an abstract in both English and Spanish.
