Abstract
The Araguaia Pantanal is characterized by a mosaic of vegetation with high biodiversity. However, our understanding of this biodiversity remains limited and understudied. Therefore, the objective of this study was to evaluate the distribution patterns of dung beetles in different vegetation types (Deciduous Forest, Savanna, Riparian Forest, Murundu Fields, and Exotic Pastures). In addition, we analyzed how forest cover influence the species richness, abundance, and species composition of dung beetles. A total of 12,746 dung beetles representing 67 different species were captured and examined. Our findings revealed that the Murundu Fields exhibited lower species richness and abundance of dung beetles, indicating the influence of distinct vegetation types directly associated with flood pulses in the region. Furthermore, the species composition of the Murundu Fields was found to be a subset of the adjacent vegetation, primarily composed of Savanna and Deciduous Forest species. Additionally, our results demonstrated that tree cover played a significant role in driving dung beetle species turnover among the studied sites, highlighting the species’ response to the existing gradient of vegetational changes within the region. We believe that our study contributes valuable insights into the distribution and ecological dynamics of dung beetles in the Araguaia Pantanal. [ABSTRACT FROM AUTHOR]
