“…The latter cannot be measured directly, for the same reason that the global diversity has yet to be quantified; it's simply too large for the methodology available. [There are several measures or indices of diversity in a population (2), but here we focus on the number of species or species richness.] The best tool for microbial detection is the rRNA approach (3), but even large 16S rRNA clone libraries seem to capture only a small fraction of the original richness.…”

Microorganisms are spectacularly diverse phylogenetically, but available estimates of their species richness are vague and problematic. For example, for comparable environments, the estimated numbers of species range from a few dozen or hundreds to tens of thousands and even half a million. Such estimates provide no baseline information on either local or global microbial species richness. We argue that this uncertainty is due in large part to the way statistical tools are used, if not indeed misused, in biodiversity research. Here we develop a powerful synthetic statistical approach to quantify biodiversity. It provides statistically sound estimates of microbial richness at any level of taxonomic hierarchy. We apply this approach to a large original 16S rRNA dataset on marine bacterial diversity and show that the number of bacterial species in a sample from marine sediments is (2.4 ؎ 0.5 SE) ؋ 10 3 . We argue that our methodology provides estimates of microbial richness that are reliable and general, have biologically meaningful SEs, and meet other fundamental statistical standards. This approach can be an essential tool in biodiversity research, and the estimates of microbial richness presented here can serve as a baseline in microbial diversity studies.global biodiversity ͉ microorganisms ͉ number of species

“…Biological diversity or "biodiversity" has been defined by the Convention on Biological Diversity (CBD) as "the variability among living organisms from all sources including Inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and of Ecosystems. This variety provides the building blocks to adapt to changing environmental conditions in the future [10]. The wildlife species is only a small component of biological diversity (biodiversity), which refers to the variety of all living organisms at the genetic, species and ecosystem levels [11].…”

Ethiopia contains one-fourth of Africa's wildlife and is comprised of 277 terrestrial mammals, 861 birds, 201 reptiles, 65 species of amphibians, 150 freshwater fish, and over 1,225 arthropods with a high rate of endemism, but It's Wildlife populations and their management are constrained by different factors. Habitat destruction, fragmentation, poaching, and lack of clear national and international policies, lack of commitment from government officials, scarcity of funds, expansion of large scale agriculture, illegal exploitation of natural resources, and lack of skilled staff are the main ones. In addition to these, Ethiopia's Ecotourism potential is huge and unmatched but the sector is in its infancy stage due to lacks of effective and sound institutional framework and legal bases for ecotourism development in related to the less emphasis and recognition given to ecotourism and also lack of cohesiveness, integrity and cooperation among the stakeholder. Most of the national parks and protected areas of the country are under pressure from the surrounding communities in search of cultivable land, grazing land, or wood for different purposes. These seminar papers give a highlight, not only on the problems of wildlife management and ecotourism in Ethiopia, but also the economic contribution and prospects of wildlife management and ecotourism in Ethiopia. It also give an over view on ecology, ecosystem and biodiversity in the area.

“…Temporal gap dynamics of forested landscapes are well-documented, but not explicitly recognized as a scale consideration in diversity assessments. Recognition of need for regional diversity investigations, as evidenced by actual funding of operations, is relatively recent.The classical view of diversity remains important for intensive studies of particular ecological communities and forest stands (Gove et al 1994, Hunter 1990, Swindel et al 1984, Swindel et al 1987, Swindel et al 1991. However, the emerging sciences of landscape ecology and conservation biology have made evident the logistical and economical impracticality of such intensive observational coverage for regions on the order of square kilometers and larger (Scott et al 1989).…”

PrefaceThis book contains 24 papers selected from among those presented at an international symposium on Measuring and Monitoring Biodivcrsity in Tropical and Temperate Forests , held in Chiang Mai, Thailand, between the 27th of August and 2nd of September, 1994. The symposium was attended by over 240 scientists from more than 40 countries from around the world. In addition to four days of paper presentations, there was also a one-day field trip, and a continuous poster session, with more than 35 posters, as well as computer demonstrations of software packages for identifying and measuring biodiversity.Biodiversity is an immense subject, and as tropical and temperate forests are home to a large proportion of the earth s terrestrial biodiversity, it is obviously very difficult to cover the topic comprehensively in a single volume. The papers included in this book were selected to give as broad a coverage as possible of key topics under the general title, including Principles of Measuring and Monitoring Biodiversity (8 papers), Genetic Diversity (6 papers), Species and Ecosystem Diversity (5 papers), and Methodology (5 papers). Inevitably, forest trees are the theme of many papers, but also included are papers dealing with diversity of arthropods, microfungi, birds and butterflies, and gibbons, as well as many papers dealing with the entire range of biodiversity.We would like to thank many people who helped to make the symposium and this book possible. Among these are the sponsors of the symposium, the Royal Forest Department of Thailand, the Commission of the European Communities, the Canadian International Development Agency (including the ASEAN Forest Tree Seed Centre and SADCC Tree Seed Centre Network), the Canadian Forest Service, the U.S. Forest Service, the Center for International Forestry Research, and the International Plant Genetic Resources Institute.We would also like to acknowledge the contribution of the entire Organizing Committee in Thailand, and particularly the assistance of Ms. Rosita Go of CIFOR, for her work before, during, and after the symposium, especially in arranging financial support for developing country scientists, and preparing the manuscripts for publication. Professor Tern had been working on wild flowers and wild plants from the very beginning of his career until the end of his life. He acquired an enormous depth of experience in botany, on his own, by trekking through all the forests and regions of Thailand. His worldwide reputation meant that any visiting botanist or forest scientist were always recommended to see him when they visited Thailand.At the end of his life, he contributed actively to the debate on forest biodiversity. He was a member of the organizing committee for the IUFRO Symposium on Measuring and Monitoring Biodiversity in Tropical and Temperate Forests , held in Chiang Mai, August 27 -September 2, 1994. He presented the keynote speech at the Symposium, which is included in these Proceedings, and led participants on a field trip to examine forest biodiversity at...
