摘要: Aim To integrate dietary knowledge and species distributions in order to examine the latitudinal, environmental, biogeographical variation richness of avian guilds (herbivores, granivores, frugivores, nectarivores, aerial insectivores, terrestrial/arboreal carnivores, scavengers, omnivores). Location Global. Methods We used global breeding range maps a comprehensive database all terrestrial bird tocalculate guild for grid cells at 110 ¥ km resolution. assessed congruence richness, quantified steepness latitudinal gradients examined covariation between climate, topography, habitat diversity biogeographic history. evaluated potential current environment history explain distribution compare observed richness‐environment relationships with those derived from random subsets pool.
