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....
Natural disasters destroy more property and kill more people with each
passing year. Volcanic eruptions, earthquakes, hurricanes, tsunamis,
floods, landslides, fires and other natural events are becoming more
frequent and their consequences more devastating. Del Moral and
Walker provide a comprehensive summary of the diverse ways in which
natural disasters disrupt humanity and how humans cope. Burgeoning
human numbers, shrinking resources and intensification of the
consequences of natural disasters have produced a crisis of unparalleled
This book is about the conservation of genetic diversity of wild plants in situ in
their natural surroundings, primarily in existing protected areas but also outside
conventional protected areas. A lot of effort has been dedicated to conserving plant
biodiversity, but most of this has focused on rare plant communities or individual
species threatened with extinction.
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.
