Conversion of land for agriculture has led to the channelisation of headwater streams and reduced water quality. Resident fish populations are expected to be challenged under such conditions and may experience declines that lead to a loss of neutral genetic variation.
Insular Southeast Asia experienced the highest level of deforestation among all humid tropical regions of the world during the 1990s.

AIM: Deforestation and climate change are two of the most serious threats to tropical birds. Here, we combine fine‐scale climatic and dynamic land cover models to forecast species vulnerability in rain forest habitats. LOCATION: Sulawesi, Indonesia.
In spatial ecology, detailed covariance analyses are useful for investigating the influences of landscape properties on fauna and/or flora species.
Aim This paper describes the development of novel indices of bird‐habitat preference to examine bird species’ use of habitats and their distributions relative to habitats. It assesses the implications for bird conservation regionally and the scope for biodiversity assessments generally.
1. The restoration of native, forested riparian habitats is a widely accepted method for improving degraded streams. Little is known, however, about how the width, extent and continuity of forested vegetation along stream networks affect stream ecosystems. 2.
Recent progress in very high spatial resolution imagery (VHSRI) has increased the availability of fine‐scale land cover data over extensive areas. This new spatial information might improve our understanding of how land cover affects stream ecosystems.
AIM: Efforts to adapt conservation to climate change are hampered by a scarcity of studies of community‐level ecological responses.
