“…Locally, the higher pollinator richness in disturbed habitats seems to be explained by higher pollinator abundance in these habitat types, which increases the chances of sampling more species. Similar responses to small-sized disturbance have also been documented for fruit feeding butterflies (Lewis 2001), and bees (Romey et al 2007). A meta-analysis conducted by Winfree et al (2009) also found positive effects (despite non significance and very large variation in effect size) of disturbance by fire and grazing on bee richness and abundance, suggesting that bee abundance might be especially favoured by small disturbed patches.…”

“…However, since species richness is not only dependent on the scale of observation (Lennon et al 2001;Rahbeck 2005), but also on the spatial scale of the disturbance, our results should not be extrapolated to large-scale disturbances, like extensive and/or long-term forest clearances and widespread forest fires where more negative effects have been observed (Spagarino et al 2001;Diaz et al 2005;Moretti et al 2006;Echeverria et al 2007). In fact, the apparent contradictory evidence of the effect of habitat disturbance on insect diversity might be partly explained not only by differences in the sampled spatial scale among studies, as exemplified by Hamer and Hill (2000), but also by the contrasting sizes of disturbed areas examined among empirical studies (e.g., Lewis 2001;Beck et al 2002;Gray et al 2007;Romey et al 2007;Winfree et al 2007;Noske et al 2008).…”

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 (

“…The disturbed areas in general support more diverse bee communities, but several bee species were shown to be forest habitat specialists (Winfree et al 2007). The effect of forest fire can be mimicked in part by logging (Romey et al 2007) or by even more controversial management efforts such as the use of herbicides such as fosamine and imazapyr (Bried and Dillon 2012).…”

Forest fire remains among the most controversial topics in nature conservation. Here, we address changes in abundance and species composition of the bee and wasp community following a temperate forest crown fire that led to nearly complete defoliation and dieback of trees within 2 years. We found a highly dynamic community of 252 bee and wasp species (representing 18.8 % of total bee and wasp species known from the Czech Republic) that utilized 1-7-year-old burned forest stands. Species richness in the burned forest stands was significantly higher than that recorded in nearby forest that had been unaffected by any recent fire. The unburned forest hosted only 88 species. We found 42 red-listed species, of which 40 were present in the burned forest, while only 12 were present in the control forest. Numerous early-and late-responding species were detected, but maximum species diversity was reached 3 years after the fire. Only 7 of the total of 261 species were limited to the forest that was unaffected by any recent fire. A management regime that supported the presence of bare sand and heather patches, and removal of all but solitary pine trees, was found to be insufficient to support the full spectrum of forest fire-dependent species. This was mainly due to the absence of charred or decaying dead wood, which is otherwise utilized by numerous redlisted cavity adopters that are absent in the surrounding cultural landscape. Retaining part of the charred trunks is suggested as a novel post-fire conservation measure.

“…This light is associated with higher understory plant species richness and abundance, especially of shade-intolerant, early-successional species (Fye 1972;Bouget and Duelli 2004;Shields and Webster 2007;Falk et al 2010). As herbaceous cover increases, so does the amount of floral resources (Romey et al 2007;Quintero et al 2010) and, despite evidence that forest loss in fragmented landscapes can be deleterious to plantpollinator interactions (Didham et al 1996;Kearns et al 1998;Steffan-Dewenter et al 2002;Taki et al , 2008, many studies in continuously forested ecosystems have shown that disturbance increases abundance and richness of insect pollinators (e.g., Bouget and Duelli 2004;Nol et al 2006;Campbell et al 2007;Romey et al 2007;Deans et al 2007). …”
