“…Both increased local populations and spill-over from undisturbed forest to disturbed forest gaps can be associated with several abiotic and biotic characteristics common to disturbed habitats such as higher light availability, increased temperature and more abundant flower resources (e.g. Feinsinger et al 1988).…”

Effects of anthropogenic habitat disturbance on local pollinator diversity and species turnover across a precipitation gradient

Anthropogenic habitat disturbance can have profound effects on multiple components of forest biotas including pollinator assemblages. We assessed the effect of small-scale disturbance on local richness, abundance, diversity and evenness of insect pollinator fauna; and how habitat disturbance affected species turnover across the landscape and overall diversity along a precipitation gradient in NW Patagonia (Argentina). We evaluated the effect of disturbance on overall pollinator fauna and then separately for bees (i.e. Apoidea) and non-bee pollinators. Locally, disturbed habitats had significantly higher pollinator species richness and abundances than undisturbed habitats for the whole pollinator assemblage, but not for bees or non-bees separately. However, significant differences in species richness between habitats vanished after accounting for differences in abundance between habitat types. At a local scale Shannon-Weaver diversity and evenness did not vary with disturbance. A b diversity index indicated that, across forest types, species turnover was lower between disturbed habitats than between undisturbed habitats. In addition, rarefaction curves showed that disturbed habitats as a whole accumulated fewer species than undisturbed habitats at equivalent sample sizes. We concluded that small patches of disturbed habitat have a negligible effect on local pollinator diversity; however, habitat disturbance reduced b diversity through a homogenization of the pollinator fauna (in particular of bees) across the landscape.Electronic supplementary material The online version of this article (

“…Vegetation structures may provide escape cover against predators, suitable nesting sites and/or food sources for birds (Feinsinger et al 1988;Lima 1993). Bamboo would appear to be the key nesting plant for the Emei Shan Liocichla at Laojunshan, given that most nests (~70 %) were found in bamboo (C. szechuanensis).…”

“…The composition of hummingbird assemblages is known to vary both through time and space (Feinsinger et al 1988, Hilty 1997, and there was some variation in how a given location was sampled. The average area covered by sites was 1.95 km 2 (median ¼ 1, range ¼ 0.07-12) and the average recorded elevational range covered was ;290 m (median ¼ 160, range ¼ 0-1900).…”

Abstract. Phylogenetic community ecology combines phylogenetic hypotheses with local species composition and functional-trait information to evaluate historical and contemporary mechanisms influencing local assemblage structure. Most studies assume that, if functional traits are conserved, then patterns of trait variation should match patterns of phylogenetic structure within local assemblages. Here we evaluated if we could predict trait structure by assuming that environmental filtering or biotic interactions work primarily on phylogenetically conserved functional traits. We investigated patterns of phylogenetic assemblage structure and functional-trait variation in bill length, wing length, and body mass in 236 hummingbird assemblages (126 species) across two major gradients in northern South America: elevation and precipitation. While mean trait values for assemblages vary predictably based on empirical knowledge of hummingbird biology, the distribution of trait values within assemblages do not correspond to those predicted based on phylogenetic signal and phylogenetic structure. Instead, we were able to identify instances where assemblages have high levels of morphological variation despite their close evolutionary relatedness and vice versa. Our results provide support for both filtering and biotic interactions across gradients, as has been documented in other studies.
