Resources and global avian assemblage structure in forests

摘要: Explaining spatial variation in a number of bird species, particularly from temperate to tropical regions, has been longstanding challenge. We test at global scale whether species-rich forest assemblages are associated with division larger resource pool, finer that or some combination the two. Species richness increases increasing assemblage abundance, biomass and energy use. As use increase availability, as per species numbers individuals, do not decrease we provide direct evidence avian species–energy relationship forests is foremost an size pool level its subdivision.
