蜣螂是大多数陆地生态系统的重要组成部分。在热带雨林中，粪甲虫群落的物种和个体数量非常丰富，并且它们被认为是栖息地干扰的有用生物指示器。相比之下，对热带干旱森林中蜣螂群落的组织知之甚少。本研究的目的是详细描述的粪甲虫社区的墨西哥热带干旱森林，并评估降雨的季节性和森林结构的相对重要性，在影响这个社会的时间和空间动态。在雨季开始时，雨季中期，旱季中期，在两种不同的森林类型：落叶林（DF）和半落叶林（SDF）在Estación de Biología Chamela的陷阱捕捉甲虫。降雨季节性和林分结构对金龟子群落结构均有影响。在两个雨季，14种被捕获，但只有3个在旱季。在旱季捕获的粪甲虫只在自卫队发现。当比较开始和中期的雨季，丰富和行会结构的差异也观察到这两个时期之间和森林类型之间，但这些差异是不太明显。
Dung beetles are important components of most terrestrial ecosystems. In tropical rain forests, dung beetle communities can be very rich in number of species and individuals, and they are known to be useful bioindicators of habitat disturbance. In contrast, very little is known about the organization of dung beetle communities in tropical dry forests. The aim of this study was to describe in detail the dung beetle community of a Mexican tropical dry forest and to assess the relative importance of rainfall seasonality and forest structure in affecting the temporal and spatial dynamics of this community. Dung beetles were captured with pitfall traps at the beginning of the rainy season, the middle of the rainy season, and the middle of the dry season, in two distinct forest types: deciduous forest (DF) and semideciduous forest (SDF) at the Estación de Biología Chamela. Both rainfall seasonality and forest structure affected the community organization of dung beetles. During both rainy periods, 14 species were captured, but only three during the dry season. Dung beetles captured during the dry season were only found in the SDF. When comparing the beginning and the middle of the rainy season, differences in abundance and guild structure were also observed between both periods and between forest types, but these differences were much less pronounced.
