Article Synopsis
- The study focuses on the relationship between local species abundance and environmental factors, addressing the knowledge gap known as the Prestonian Shortfall, particularly for small mammals in the Atlantic Forest.
- Researchers compiled a comprehensive dataset from 114 sources, capturing 1,902 records of at least 111 small mammal species across 155 sites, with detailed information on various ecological parameters and study specifics.
- The dataset provides a valuable resource for exploring community and geographical ecology patterns, including how local abundance relates to environmental conditions, species diversity, and community dynamics within the Atlantic Forest biome.
Our objective was to estimate and analyze the body-size distribution parameters of terrestrial mammal assemblages at different spatial scales, and to determine whether these parameters are controlled by local ecological processes or by larger-scale ones. Based on 93 local assemblages, plus the complete mammal assemblage from three continents (Africa, North, and South America), we estimated three key distribution parameters (diversity/size slope, skewness, and modal size) and compared the values to those expected if size distributions are mainly controlled by local interactions. Mammal diversity decreased much faster as body size increased than predicted by fractal niche theory, both at continental and at local scales, with continental distributions showing steeper slopes than the localities within them.
