| Popis: | Faunistical and ecological studies are lacking on dung beetles in the xerophytic scrublands at Villa de Cos, Zacatecas, of the Mexican Plateau Province. This study analyzed the effect of season and vegetation type on community structure. Pitfall traps baited with human dung were sampled at six sites on three dates (early rainy season, dog days, and late rainy season). In total, 4,040 beetles in 17 species were trapped. Vegetation type and sampling season affected average dung beetle abundance, species richness, and Simpson diversity index. Scrublands had more abundance and richness but least diversity than grasslands. Abundance diminished during dog days but richness increased during this season and the rains after it. Diversity had an inverse pattern with more during early rains than during the dog days or late rains. The community structure was determined by microhabitats for nesting provided by the combination of vegetation type and soil compaction. Telecoprids like Canthon humectus (Say) wer... |
