Multimodality in the Individual Size Distributions of Bird Communities
Global Ecology and Biogeography
Body size often plays a significant role in community assembly through its impacts on the life history and ecological attributes of species. Insight into the importance of size in structuring communities can be gained by examining the distribution of sizes of individuals(i.e., the individual size distribution (ISD) or size spectrum) in a community. ISDs have been studied extensively in aquatic and tree communities, but have received little attention in terrestrial animal communities. Here, we conduct the first macroecological analysis of ISDs in terrestrial animal communities to determine whether they show broad-scale consistency in shape.
