Effects of habitat transitions on rainforest bird communities across an anthropogenic landscape mosaic
<p>We compared bird community responses to the habitat transitions of: rainforest-to-pasture conversion, consequent habitat fragmentation, and post-agricultural regeneration, across a landscape mosaic of <span>about </span><span><span>600 km<sup><span>2</span></sup></span></span><span> in the eastern Australian subtropics. Birds were surveyed in seven habitats: continuous mature rainforest; two size-classes of mature rainforest fragment (4-21 ha, 1-3 ha); regrowth forest patches dominated by a non-native tree (2-20 ha, 30-50 years old); two types of isolated mature trees in pasture; and treeless pasture; with six sites per habitat. We compared the avifauna among habitats, and among sites, at the levels of species, functional guilds, and community-wide. Community-wide species richness and abundance of birds in pasture sites were about one-fifth and one-third, respectively, of their values in mature rainforest (irrespective of patch size). Many measured attributes changed progressively across a gradient of increased habitat simplification. Rainforest </span><span><span>specialists</span></span><span> became less common and less diverse with decreased habitat patch size and vegetation maturity. However, even rainforest fragments of 1-3 ha supported about half of these species. Forest generalist species were largely insensitive to patch size and successional stage. </span><span><span>Few</span></span><span> species reach</span>ed their greatest abundance in either small rainforest fragments or regrowth. All pastures were dominated by bird species whose typical native habitats were grassland, wetland and open eucalypt forest, while pasture trees modestly enhanced local bird communities. Overall, even small scattered patches of mature and regrowth forest contributed substantial bird diversity to local landscapes. Therefore, maximising the aggregate rainforest area is a useful regional conservation strategy.</p>

Anthropogenic habitat modification causes nonlinear multiscale bird diversity declines
<p>Anthropogenic habitat modification is a leading contributor to biodiversity change, but it is unclear what factors, including scale, influence the magnitude of change. Changes in species richness and its scaling relationship across an anthropogenic gradient can be influenced by changes in the total number of individuals in each sample, the species abundance distribution, and/or the spatial arrangement of conspecific individuals. Here, we integrated continental-scale citizen science data on bird occurrences across the contiguous United States — from eBird — with an analytical framework capable of dissecting<em> </em>the aforementioned biodiversity components to quantify bird diversity changes along an anthropogenic landscape habitat modification gradient. We found an overall decline in bird diversity along an anthropogenic modification gradient, with peak levels of bird diversity at low to moderate levels of modification. The magnitude of biodiversity change was greater at gamma than at alpha scales and was most strongly associated with a declining number of individuals along the anthropogenic gradient. Spatial species turnover was lower at higher impacted sites, but this was also due to the sampling of fewer individuals rather than changes in spatial species patchiness. Our results suggest that local-scale management can promote bird diversity, especially at the natural-rural-suburban interface. Management efforts (e.g., managing natural habitat or preserving urban greenspaces against development) should be focused on creating, restoring, and preserving resources (e.g., nesting habitat, foraging resources) necessary for a large number of individuals, as this is the primary influence of diversity change along an anthropogenic gradient.</p>
