  • Focusing on the rich biodiversity of Costa Rica, the contributors demonstrate the use of geographic information systems (GIS) to enhance conservation efforts. They give an overview of the spatial nature of conservation and management and the current status of digital mapping in Costa Rica; a review of the basic principles behind digital mapping technologies; a series of case studies using these technologies at a variety of scales and for a range of conservation and management activities; and the results of the Costa Rican gap analysis project....

  • The world ocean has somewhere between 10 000 and 100 000 seamounts more than 1 km tall and as many as 1 000 000 features over 100 m tall. These are some of the least understood habitats on the planet. Large seamounts, particularly those close to or within the photic zone, support and attract rich biotic communities and are important for the status of marine food webs and biodiversity. Intensive boom-and-bust fi sheries have depleted fi sh populations and damaged or destroyed associated benthic communities.

  • Widespread thermal anomalies in 1997–1998, due primarily to regional effects of the El Nin˜ o–Southern Oscillation and possibly augmented by global warming, caused severe coral bleaching worldwide. Corals in all habitats alongthe Belizean barrier reef bleached as a result of elevated sea temperatures in the summer and fall of 1998, and in fore-reef habitats of the outer barrier reef and offshore platforms they showed signs of recovery in 1999. In contrast, coral populations on reefs in the central shelf lagoon died off catastrophically.
