This book was released on 2008-04-08 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diploma Thesis from the year 2006 in the subject Biology - Ecology, grade: 1,0, University of Applied Sciences Bremen, language: English, abstract: A key question of plant ecology is which factors control the local distribution of plant species and plant communities. Thus the appearance of scattered tree dominated fertile patches in generally nutrient-poor savanna grassland is an interesting phenomenon. As trees alter structural and spatial variability of the environment they increase floral and faunal diversity. Under favourable conditions such patches may increase in size until they merge with each other and a closed canopy forest builds up. However, in dry areas successive invasion into grassland is blocked and there is little spread outwards. Research was conducted from September 2005 to January 2006 in the Western Soutpansberg, South Africa. For Mimusops zeyheri and Syzygium legatii effects of shade and seed size on germination and seedling recruitment have been investigated in plant pot experiments. Two field experiments were conducted investigating seed predation and the effect of competition. Additionally, recruitment was studied at eight tree islands and soil samples from 96 plots varying in exposition, habitat type and location of sampling site were analysed. Results revealed that tree recruitment was influenced by complex interactions between facilitation and competition, herbivory and abiotic environmental stress. Soil moisture availability, browsing and competition with grasses seem to be the primary factors limiting a rapid expansion of the tree islands into the surrounding grassland. Seed predation slightly reduces seed availability but is not limiting recruitment. Large-seeded seedlings had a higher chance of establishment. Key words: tree recruitment, islands of fertility, savanna, gradients, competition, Soutpansberg

Download or read book Livelihood and Landscape Change in Africa Future Trajectories for Improved Well Being under a Changing Climate written by Sheona Shackleton and published by MDPI. This book was released on 2019-10-08 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on a Special Issue of the journal LAND that draws together a collection of 11 diverse articles at the nexus of climate change, landscapes, and livelihoods in rural Africa; all explore the links between livelihood and landscape change, including shifts in farming practices and natural resource use and management. The articles, which are all place-based case studies across nine African countries, cover three not necessarily mutually exclusive thematic areas, namely: smallholder farming livelihoods under new climate risk (five articles); long-term dynamics of livelihoods and landscape change and future trajectories (two articles); and natural resource management and governance under a changing climate, spanning forests, woodlands, and rangelands (four articles). The commonalities, key messages, and research gaps across the 11 articles are presented in a synthesis article. All the case studies pointed to the need for an integrated and in-depth understanding of the multiple drivers of landscape and livelihood change and how these interact with local histories, knowledge systems, cultures, complexities, and lived realities. Moreover, where there are interventions (such as new governance systems, REDD+ or climate smart agriculture), it is critical to interrogate what is required to ensure a fair and equitable distribution of emerging benefits.

Download or read book African Predators written by M. G. L. Mills and published by . This book was released on 2001 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large carnivores reign supreme in the African wild - superior, powerful, skillful and feared. From the big cats to the endangered wild dog and Ethiopian wolf, the often-maligned hyenas and the opportunistic jackel, these hunters captivate, fascinate and excite, and provide the raw drama of Africa, sought after by many wildlife lovers. This text brings many years of study and practical research in revealing the origins, the present struggle for survival and the uncertain future of Africa's predatory mammals. The examination of their behaviour, social make-up, relations and interactions is supported by dramatic photography.

Available in PDF, EPUB and Kindle. Book excerpt: This edited collection examines contemporary directions in geographical research on South Africa. It encompasses a cross section of selected themes of critical importance not only to the discipline of Geography in South Africa, but also of relevance to other areas of the Global South. All chapters are original contributions, providing a state of the art research baseline on key themes in physical, human and environmental geography, and in understanding the changing geographical landscapes of modern South Africa. These contributions set the scene for an understanding of the relationships between modern South Africa and the wider contemporary world, including issues of sustainable development and growth in the Global South.
