Vegetation Structure and Soil Composition Influence Opiliones Diversity Across Spatial Scales in Amazonia

A study in the Central Amazon Conservation Complex reveals that Opiliones (harvestmen) diversity is influenced by vegetation structure and soil composition, but these effects vary significantly across spatial scales. While local-scale diversity is higher in tree trunks, branches, and leaves due to microhabitat variety, regional-scale diversity is linked to soil and sand content rather than tree density. This scale-dependent relationship underscores the importance of protecting diverse microhabitats, such as mature forests and large trees, for arthropod conservation, while also considering broader geographic factors that may affect species diversity.
