The 22 species of Megapodes or "thermometer-birds" are found in Australia, New Guinea, eastern Indonesia, the Philippines and some Pacific islands. With changing traditions and demographic patterns, and habitat loss, uncontrolled harvesting has reduced some populations to a point where sustainable use has become untenable.
More than 1,000 species of molluscs are threatened by habitat destruction, over-collection, or predation by alien species. The nine papers and five abstracts in this volume summarise the current status of molluscan diversity.
The rationale for this three-volume work covering nearly 250 major sites for conservation of plant diversity worldwide is concern about rapid global loss and degradation of natural ecosystems. By highlighting areas of prime botanical importance, it is hoped that their conservation will be ensured by an adequate commitment of resources. Selection of the sites is based both on floristic statistics and on detailed first-hand knowledge of numerous botanists.
This work draws attention to the conservation problems confronting these species. The general lack of knowledge about this group has meant that they are afforded little protection.
This book deals with the different types of soil and the soil characteristics of mangrove swamps, the flora and invertebrate fauna as well as with the vertebrate fauna. Furthermore the book informs about the settlement and development of mangroves as well as with the management and utilization of forest resources. Also topics like fishery and agriculture and conservation of biological resources are shown in detail.
