Birds in agricultural mosaics: the influence of landscape pattern and countryside heterogeneity.

摘要: Agricultural environments are critical to the conservation of biota throughout world. Efforts identify key influences on status fauna in such have taken complementary approaches. Many studies focused role remnant or seminatural vegetation and emphasized influence spatial patterns landscape. Others recognized that many species use diverse “countryside” elements within farmland, emphasize benefits landscape heterogeneity for conservation. Here, we investigated effect independent measures both pattern (extent configuration) (i.e., land uses/vegetation types) bird occurrence farm-scale agricultural mosaics southeastern Australia. Birds were sampled all types 27 (each 1 × km) selected incorporate variation cover native number different element mosaic. We used an information-theoretic...
