Download or read book Effects of Anthropogenic Disturbance on the Diversity of Foliicolous Lichens in Tropical Rainforests of East Africa: Godere (Ethiopia), Budongo (Uganda) and Kakamega (Kenya) written by Kumelachew Yeshitela and published by Cuvillier Verlag. This book was released on 2008 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foliicolous lichens are one of the most abundant epiphytes in tropical rainforests and one of the few groups of organisms that characterize these forests. Tropical rainforests are increasingly affected by anthropogenic disturbance resulting in forest destruction and degradation. However, not much is known on the effects of anthropogenic disturbance on the diversity of foliicolous lichens. Understanding such effects is crucial for the development of appropriate measures for the conservation of such organisms. In this study, foliicolous lichens diversity was investigated in three tropical rainforests in East Africa. Godere Forest in Southwest Ethiopia is a transitional rainforest with a mixture of Afromontane and Guineo-Congolian species. The forest is secondary and has been affected by shifting cultivation, semi-forest coffee management and commercial coffee plantation. Budongo Forest in West Uganda is a Guineo-Congolian rainforest consisting of primary and secondary forests. Kakamega Forest in western Kenya is a transitional rainforest with a mixture of Guineo-Congolian and Afromontane species. The forest is a mosaic of near-primary forest, secondary forests of different seral stages, grasslands, plantations, and natural glades.

The forest is a mosaic of near-primary forest, secondary forests of different seral stages, grasslands, plantations, and natural glades. Leaves carrying foliicolous lichens were collected from the forest understorey in the shady understorey and light gap microsite regimes. Morphological and anatomical characters were used for the identification of foliicolous lichens. Different indices were used for the computation of α- and β-diversity. The biogeographical distribution patterns of the foliicolous lichens of the study area and the possible use of foliicolous lichens as indicator of forest disturbance were analysed. A total of 70 species of foliicolous lichens and lichenicolous fungi belonging to 27 genera and 15 families were recorded from Godere Forest. From Budongo Forest 125 species of foliicolous lichens & lichenicolous lichens belonging to 32 genera and 16 families were recorded. From Kakamega Forest 137 species belonging to 41 genera and 17 families were recorded. In addition, 7 foliicolous lichens new to science have been recorded in this study. The most species-rich families in both forests were Pilocarpaceae, Porinaceae, Gomphillaceae, and Strigulaceae. In Godere higher foliicolous lichen diversity was recorded in Dushi than in Bishan Waka forest site. In Budongo high foliicolous lichen diversity was recorded in the young secondary and the primary swamp forests. In Kakamega Forest high foliicolous lichen diversity was recorded in the sites of Yala, Buyangu, Isiukhu, and Kisere. Low diversity was recorded in Malava, Kaimosi and Camp site. Among the 3 forests investigated, α- diversity was significantly higher in Kakamega and Budongo than in Godere forest. β- diversity was high in Kakamega and Budongo and low in Godere. Several studies have shown higher foliicolous lichen diversity in undisturbed primary forests than in disturbed secondary forests. Our study showed high foliicolous lichen diversity in both primary.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical forest mutualisms are under threat from increased rates of forest conversion and degradation. Seed dispersal and regeneration is important for maintenance of both trees and frugivores. To elucidate the effect of small-scale anthropogenic disturbance on frugivore community and the vital ecosystem process of seed dispersal and regeneration I investigated (1) the frugivore community and fruit removal rates of Celtis durandii (Ulmaceae) and (2), the relationship between fleshy-fruited tree species, frugivores and fleshy-fruited tree seedling establishment in three East African tropical rainforests. During frugivore community census I recorded 40 frugivorous birds and primates in the three forests. Moreover, I recorded more frugivores in little disturbed sites as compared to heavily disturbed sites. From observations on C. durandii trees I recorded more frugivore visitors on trees located in little disturbed than in heavily disturbed sites. This lead to marginally more seeds removed by frugivores in little disturbed than in heavily disturbed sites. The results did not differ among the three rainforests, suggesting that they were consistent at a regional scale. Therefore, it appears that small-scale forest disturbance has a more general negative impact on frugivores and their seed dispersal services than previously anticipated. During the vegetation survey I recorded 131 fleshy-fruited tree species in the three rainforests. Small-scale human disturbance marginally significantly enhanced fleshy-fruited tree species richness with no direct effect on frugivore density and species richness of fleshy-fruited tree seedlings. Richness of fleshy-fruited trees had a marginally significant positive influence on frugivore density but not on seedlings. Correspondingly, the density of frugivores significantly increased the species richness of fleshy-fruited tree seedlings. Thus, small-scale disturbance appear to have increased seedling establishment indirectly through increas.

Book Synopsis Urban Vulnerability and Climate Change in Africa by : Stephan Pauleit
Download or read book Urban Vulnerability and Climate Change in Africa written by Stephan Pauleit and published by Springer. This book was released on 2015-04-13 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urbanisation and climate change are among the major challenges for sustainable development in Africa. The overall aim of this book is to present innovative approaches to vulnerability analysis and for enhancing the resilience of African cities against climate change-induced risks. Locally adapted IPCC climate change scenarios, which also consider possible changes in urban population, have been developed. Innovative strategies to land use and spatial planning are proposed that seek synergies between the adaptation to climate change and the need to solve social problems. Furthermore, the book explores the role of governance in successfully coping with climate-induced risks in urban areas. The book is unique in that it combines: a top-down perspective of climate change modeling with a bottom-up perspective of vulnerability assessment; quantitative approaches from engineering sciences and qualitative approaches of the social sciences; a novel multi-risk modeling methodology; and strategic approaches to urban and green infrastructure planning with neighborhood perspectives of adaptation.

Book Synopsis The Lichen-Forming Fungi by : D. L. Hawksworth
Download or read book The Lichen-Forming Fungi written by D. L. Hawksworth and published by Springer. This book was released on 1984-09-01 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lichen assocIations include some of the oldest living organisms and represent a major nutritional method adopted by one in five fungi. Major advances in our knowledge of these biologically fascinating organisms have been made in recent years and they now have a great deal to offer to teaching in colleges and universities. In addition to being examples of biotrophic systems, they merit discussion in courses on fungal phylogeny, fungal nutrition, ecology, ecophysiology, biogeography, evolution, chemo taxonomy, environmental monitoring, and algology. As all aspects of lichenology cannot be treated adequately in a book of this length, we have emphasized topics which we have found to be of particular interest to a advanced undergraduate and postgraduate biologists (or biogeographers) or those contemplating more detailed studies in particular areas. Consequently we have endeavoured to place lichen associations in the broader context of biological and biogeographical teaching. Examples are drawn from many areas of the world, including North America, but it is inevitable that European ones predominate, as lichens there are better known than in other regions. Technical terms are defined when first used, and definitions can therefore be located with the aid of the index. Lichens are not a systematic group and so are not appropriately treated in a groups-orientated programme, but are a major biological phenomenon all too commonly accorded scant attention in university courses.
