We reviewed published literature to examine the effect of habitat fragmentation on avian
nesting success at three spatial scales (ie, edge, patch, and landscape scales). We …

Numerous studies have analyzed predation risk on bird nests along forest edges, but results
are inconsistent and contributing factors not well understood. Few of these studies have …

A majority of empirical tests have failed to support the hypothesis that avian nest predation
increases near habitat edges. Of 54 study sites, 13 exhibited an edge effect in any test …

Avian insectivores of the tropical rainforest understory (“understory insectivores”) are
common, diverse, and often sensitive to disturbance of tropical forest, making them useful as …

We compared the composition and structure of primary forest avifauna among primary
forests, selectively logged forests and mixed-rural areas (eg villages and agricultural areas) …

Primary tropical lowland rainforest in Sabah, Malaysia, has been largely reduced to small to
medium-sized, often isolated, forest islands surrounded by a highly altered agricultural …

One possible mechanism underlying species losses in the tropics is an increase in
predation due to habitat degradation. Relative levels of predation at three heights (ground, 1 …

In the wet tropics of north-eastern Queensland, the composition of the small-mammal
community close to the edge of an unsealed rainforest road differed from that of the forest …

Tropical forest understory birds are declining globally for unknown reasons, indicating an
urgent need to understand the causes. We review and synthesize studies investigating …
