Available in PDF, EPUB and Kindle. Book excerpt: Extending from west Africa to Madagascar, from the vast lowland Congo Basin to the archipelago of forest islands on its eastern rim, the African rain forest is surpassed in size only by the Amazon. This book sheds light on the current efforts to understand and conserve the African rain forest, an area in need of urgent action to save its biological wealth, cultural heritage, and economic potential. Written by conservation scientists and practitioners based in the African rain forest, the book offers a multidisciplinary perspective that integrates many biological and social sciences. Early chapters trace the forces--from paleoecological factors to recent human actions--that have shaped the African forest environment. The next chapters discuss the dominant biological patterns of species ranging from the distinctive elephants, gorillas, and okapi to the less well known birds, butterflies, and amphibians. Other chapters focus on how such different groups as hunter-gatherers, forest farmers, bushmeat hunters, recent immigrants, and commercial foresters have used the forests. Several authors stress the need for tighter links between research and conservation action. The final section draws lessons from the collective experience of those working in an Africa wracked by political strife and economic hardship.

This book was released on 2006-04-11 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been twelve years since a work relating to the long-tailed African monkeys known as the guenons has been published and fifteen years have passed since the last major scientific symposium was held that was solely dedicated to current research on members of this monkey group living in the wild. Since that time, new guenon species and subspecies have been discovered, previously unstudied guenon species have become the subject of long-term research projects, and knowledge of the more well-known guenon species has greatly increased. This volume presents novel information and keen insight on research previously studied and newly discovered. A wide range of topics related to guenon biology is presented, including evolution, taxonomy, biogeography, reproductive physiology, social and positional behavior, ecology, and conservation. Composed of 26 chapters compiled by 47 authors, many of whom are young investigators in their field, The Guenons: Diversity and Adaptation in African Monkeys provides a valuable resource for researchers and scientists in the fields of anthropology, primatology, zoology, and conservation biology.

This book was released on 2006-10-30 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: The montane rainforests of Ethiopia are the center of origin and genetic diversity of Coffea arabica L. (Rubiaceae). They form part of the Eastern Afromontane biodiversity hotspot due to the high threat of deforestation. Concepts for conservation of these forests and their wild coffee populations are urgently needed. For the present study, vegetation surveys were carried out in four forest fragments in the Bonga region (southwestern Ethiopia) situated between 1,560 and 2,280 m asl. A total of 309 vascular plant species including 16 endemics were recorded; 36 % of the species occur in all forest fragments, while 43 % are present in one fragment only. Ordination methods reveal that plant species composition is strongly influenced by the altitudinal gradient. The forest fragment Koma, which is located above 1,800 m asl, is characterized by high pterophyte diversity and high abundance of Afromontane endemics or near endemics. Forest below 1,800 m asl has a greater diversity of tree species and pytogeographical elements, and is further divided in a moister type (Mankira forest fragment) and a drier type (Kayakela forest fragment). Many species of the understory are frequent and abundant, so that the representative species number for a forest fragment can be captured with 10 study plots. In contrast, many tree species and epiphytes have low frequency, and the recording of their representative species number in a forest fragment requires 29 study plots. Wild coffee grows throughout the forest until 2,050 m asl except for extremely shaded and humid sites. Growth rates are very low, in particular during the main rainy season from July until October. Most wild coffee populations are utilized by local farmers. Three use types can be differentiated: (1) Unmanaged wild coffee has very low density in the shaded understory of undisturbed forest. Yields (clean coffee) are below 5 kg ha-1 a-1. (2) Forest coffee systems with low management intensity have an undisturbed forest structure, but some undergrowth vegetation is removed systematically. Abundance and size of coffee trees increase, and yields can reach 15 kg ha-1 a-1. (3) In semi-forest coffee systems, management intensity is high and forest structure is disturbed. Most undergrowth vegetation besides coffee is cleared at least once a year and some canopy trees are cut. Removal of competing plants and increased light penetration stimulate wild coffee growth. Yields average 35 kg ha-1 a-1. Low management intensity in forest coffee systems does not modify natural species composition. Abundance and distribution of tree species in unmanaged forest and forest coffee systems are currently governed by natural dynamics, but increasing demand for wood is likely to cause over-exploitation of some highly valued secondary forest and climax tree species. In semi-forest coffee systems, slashing of vegetation and related modification of forest microclimate have a strong impact on species composition and species population structures. Most mature individuals of woody species are coppiced, which favors species that regenerate well vegetatively. Species richness increases due to high numbers of ruderal herbs, climbers and pioneer species adapted to regeneration in disturbed sites. In contrast, the number and abundance of typical forest species that require shade and humidity decline. This is most pronounced regarding tree species. This study makes suggestions for a conservation concept that combines both protection of the original plant diversity of Afromontane forest and profitable use of wild coffee.

This book was released on 2023-04-10 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rain forests represent the world's richest repository of terrestrial biodiversity, and play a major role in regulating the global climate. They support the livelihoods of a substantial proportion of the world's population and are the source of many internationally traded commodities. They remain (despite decades of conservation attention) increasingly vulnerable to degradation and clearance, with profound though often uncertain future costs to global society. Understanding the ecology of these diverse biomes, and peoples' dependencies on them, is fundamental to their future management and conservation. Tropical Rain Forest Ecology, Diversity, and Conservation introduces and explores what rain forests are, how they arose, what they contain, how they function, and how humans use and impact them. The book starts by introducing the variety of rain forest plants, fungi, microorganisms, and animals, emphasising the spectacular diversity that is the motivation for their conservation. The central chapters describe the origins of rain forest communities, the variety of rain forest formations, and their ecology and dynamics. The challenge of explaining the species richness of rain forest communities lies at the heart of ecological theory, and forms a common theme throughout. The book's final section considers historical and current interactions of humans and rain forests. It explores biodiversity conservation as well as livelihood security for the many communities that are dependent on rain forests - inextricable issues that represent urgent priorities for scientists, conservationists, and policy makers.
