Understanding global biodiversity patterns requires analyses at multiple spatial and temporal scales, across a variety of different habitat types. We used a highly replicated study in coastal Ecuador to examine simultaneously for the first time spatial and temporal species turnover and the contribution of five different habitat types (rice, pasture, coffee agroforests, abandoned coffee agroforests, and native forest fragments) to regional diversity in the tropics, using the experimental placement of standardized nesting structures for bees and wasps. There was notable overlap in the communities of different habitat types, indicating that even intensively managed land can provide a valuable contribution to the overall biodiversity of the landscape mosaic. Importantly, there was a significant effect of habitat type on temporal variation in diversity. While intensive cropping systems such as rice and pasture exhibited higher diversity in certain months, greater species turnover through time in the abandoned coffee and forest plots accounted for the higher overall diversity in these habitats. Overall, spatial and temporal turnover explained 38.6% and 23.1%, respectively, of partitioned regional species richness. A quantitative analysis revealed that the relative habitat specificity of Hymenoptera decreased with increasing habitat disturbance.

Contrasting responses of bee communities to coffee flowering at different spatial scales (2006, background): “Factors driving biodiversity are known to be scale-delimited such that variables accounting for species richness on a smaller scale may operate differently on broader scales (Crawley and Harral 2001, Steffan-Dewenter et al. 2001, Willis and Whittaker 2002, Tylianakis et al. 2005 ).”
Shade tree management affects fruit abortion, insect pests and pathogens of cacao (2007, background): “Such losses are regulated by the plant, primarily as a response to pollen incompatibility (Hasenstein and Zavada, 2001) and nutrient limitations that result from low photosynthetic rates or poor soils (Nichols and Walmsley, 1965; Valle et al., 1990).”

Resource Heterogeneity Moderates the Biodiversity-Function Relationship in Real World Ecosystems (2008, background): “Of all the potential host species found in our traps [60], the one with the greatest diversity of parasitoids attacking it (six species) was Pseudodynerus sp.”
Weed-insect pollinator networks as bio-indicators of ecological sustainability in agriculture. A review (2016, background): “The foraging activity and the specialization are strongly linked to the relationship between the flowering phenology and the biological traits of visiting insects (Westrich 1989; Fenner 1998; Tylianakis et al. 2005; Michener 2007; Mader et al. 2011).”
Functional group diversity of bee pollinators increases crop yield (2008, background): “Spatial niche partitioning of pollinator communities (e.g. Willmer & Corbet 1981; Tylianakis et al. 2005) results in certain bee species being observed foraging at certain heights, which may have been selected to minimize energy expenditure (Hambäck 2001; Dafni & Potts 2004).”
