摘要

摘要:Woodhouse’s scrub-jay (Aphelocoma woodhouseii texana)是栖息于美国德克萨斯州中部杉木灌丛和林地的一种研究相对较少的亚种。我们估计了密度，并检查了它们繁殖范围东部边缘的栖息地关联。在100 m尺度上，灌丛鸦与中等比例的松柏土地覆被密切相关，在1 km尺度上，混交林和城市土地覆被较多的地区，灌丛鸦的密度较低。

DENSITY AND HABITAT ASSOCIATIONS OF THE WOODHOUSE'S SCRUB-JAY IN CENTRAL TEXAS

Abstract Woodhouse's scrub-jay (Aphelocoma woodhouseii texana) is a relatively understudied subspecies inhabiting juniper scrub and woodland in central Texas. We estimated density and examined habitat associations at the eastern edge of their breeding range. Scrub-jays were strongly associated with intermediate proportions of juniper land cover at a 100-m scale and showed lower density in areas of greater mixed oak-juniper woodland and greater urban land cover at a 1-km scale.

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.
