The following research and reviews will appear in the December issue of Frontiers in Ecology and the Environment.

Coho salmon dependence on intermittent streams

Early this year, the US Supreme Court remanded to a lower court cases relating to whether intermittent streams are under the jurisdiction of the Clean Water Act. Intermittent streams are currently threatened by the possible outcomes of the court cases. In this study, P.J. Wigington Jr. (US Environmental Protection Agency) and colleagues found that intermittent streams are an important source of coho salmon (Oncorhynchus kisutch) smolts. Residual pools in these streams provide a place for the juvenile salmon to survive during dry periods. Their research suggests the loss of these habitats would have a negative effect on coho salmon populations.

Sacred groves: potential for biodiversity management

While global protected areas, including nature reserves, parks, and areas protected by treaties, protect some aspects of biodiversity, shortcomings remain: the areas only cover certain habitats and local people often resent their formal management. Natural sacred sites exist in many countries around the world, with communities often sharing and managing sites that are not under formal protection. Such sites cover a wide variety of habitats and are often located in biodiversity hotspots. Shonil Bhagwat (Natural History Museum, London and University of Oxford) and Claudia Rutte (University of Bern, Switzerland) propose that such habitats should be included in biodiversity management.

Although 23 percent of Earth's tropical forests are formally protected, only 8 percent of cropland and natural vegetation mosaic habitats receive the same protection. Natural sacred sites, protected by local traditions, are often situated within agricultural landscapes, providing corridors for wildlife. These sites come in many forms, including burial grounds and sites of
