Predicting Long-Term Changes in Riparian Bird Communities in Floodplain Landscapes

摘要: As anthropogenic impacts on riverine ecosystems expand, both aquatic and terrestrial are influenced over large spatiotemporal scales. We predicted how riparian bird communities changed in response to long-term changes floodplain landscapes such as woodland expansion (i.e. rapid increases vegetation cover gravel bars the progress of succession due a decrease frequency magnitude flood disturbance). To test hypothesis that after dam construction reduces abundance bar-nesting birds forest-nesting birds, we estimated historical between past present abundances using species distribution models across multiple rivers were either unregulated or regulated by dams. created maps from remote sensing images used habitat quantities explanatory variables models. hypothesized, decreased increased because some rivers. This suggests alterations conditions (e.g. construction) can affect communities) through floodplains expansion). In addition, our findings highlight efficacy combining spatial temporal analyses when examining ecological dynamics. Copyright © 2013 John Wiley & Sons, Ltd.
