The contributors consider how social science perspectives can contribute to our understanding of communities and their conflicting choices regarding the allocation and use of forest, agriculture and other natural resources. The topics discussed include community stability, community adjustment to economic and technological change and the public's r
Meiobenthology is the science of the tiny animals that live in huge numbers in all aquatic sediments. This fully revised and enlarged second edition emphasizes new discoveries and developments in this field. Major progress has been made in three general areas: - Systematics, diversity and distribution, - Ecology, food webs, and energy flow, - Environmental aspects, including studies of anthropogenic impacts. The meiobenthos of polar and tropical regions, deep-sea bottoms and hydrothermal vents are now studied in more detail. The high number of species found to survive under such extreme conditions puts them at the forefront of biodiversity studies. Molecular screening methods enable large numbers to be analyzed upon applying reasonable effort. The aim of this book is to synthesize these modern scientific achievements such that meiobenthology can play a key role in aquatic research and in assessing the health of our environment.
National parks are a global phenomenon found in more than 120 countries. These parks are as diverse as the physical settings and cultural patterns of the many nations that have established them, yet within each country they serve as part of the cohesiveness that binds people together. Parks reflect-and help create-people's pride and love for their national heritage.
