Response of each species to proportion of forest cover at a landscape scale.

<p>(a, c) Relationships between abundance of each species and proportion of forest cover at a landscape scale and (b, d) pie charts showing the proportions of species with the four categories of response type (open-habitat species, mosaic-habitat species, forest species, and no response) among (a, b) 38 wide-ranging species, and (c, d) 19 narrow-ranging species. Regression lines for each species were calculated in the same way as those for species richness (see explanation in the caption to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0093359#pone-0093359-g002" target="_blank">Figure 2</a>). Criteria for categorization of each species according to the proportion of forest cover are given in the text.
