Última Variation in Native Bee Faunas and its Implications for Detecting Community Changes Ecology and Society Williams, Neal M; University of Calgary; nwilliam@ucalgary.ca; Minckley, Robert L; University of Utah; minckley@biology.utah.edu; Silveira, Fernando A; Universidade Federal de Minas Gerais; fernando@mono.icb.ufmg.br. Changes in flower-visiting insect populations or communities that result from human impacts can be documented by measuring spatial or temporal trends, or by comparing abundance or species composition before and after disturbance. The level of naturally occurring variation in populations and communities over space and time will dictate the sampling effort required to detect human-induced changes. We compiled a set of existing surveys of the bee faunas of natural communities from around the world to examine patterns of abundance and richness. We focused on a subset of these studies to illustrate variation in bee communities among different sites and within sites over different spatial and temporal scales. We used examples from our compilation and other...
