Book Description
African ecosystems comprise a wealthy repository of biodiversity, with a high proportion of native and endemic plant species, which makes them biologically unique and providers of a wide range of ecosystem services. A large part of African populations, in both rural and urban areas, depend on plants for their survival and welfare, but many ecosystems are being degraded, mostly due to the growing impacts of climate change and other anthropogenic actions and environmental problems. Loss of habitat and biodiversity affects livelihoods, water supply and food security and reduces the resilience of ecosystems in the African continent. The knowledge about the great African plant and ecosystem diversity, and the structure, composition and processes involved in vegetation dynamics, is crucial to promote their sustainable use and to preserve one of the most understudied regions in the world. This Special Issue aimed to gather contributions that update and improve such knowledge.

Book Description
Human Biological Diversity is an introductory textbook designed to cover the key contemporary topics in the study of human variation and human biology within the field of physical anthropology. Easily accessible for students with no background in anthropology or biology, this second edition includes two new chapters, one on human variation in the skeleton and dentition and the other on tracing human population affinities. All other chapters have been fully updated to reflect advances in the field and now include pedagogical features to aid readers in their understanding. Written for an introductory level but still containing valuable information that will be of interest to students on upper-level courses, Brown’s textbook should be essential reading for all students taking courses on human variation, human biology, human evolution, race, anthropology of race, and general introductions to biological/physical anthropology.

Book Description
This volume, the second in the Lectures in Climate Change series, covers the full array of climate impacts and adaptation measures. It has been brought together by friends and colleagues of Dr Martin Parry, Co-Chair of the Intergovernmental Panel on Climate Change (IPCC) 2007 assessment on impacts and adaptation. The writers are experts in this field and have been lead authors in many of the IPCC assessments and other major publications.Lectures in Climate Change is a unique combination of written text plus electronic slides that together comprise an informative and up-to-date set of presentations. This second volume, entitled Our Warming Planet: Climate Change Impacts and Adaptation, covers areas of climate impacts related to climate science, methods and approaches, sectors, regional and national studies, and policy and practice.The volume comprises topics such as current and future challenges of climate change, global assessments, downscaling, community-based adaptation, impacts on biodiversity, food systems, water resources, and cities. Research from across the world is presented on making science actionable through assessments, early warning and early action, communicating climate risk, documenting the uptake of adaptation on the global front, and transformation towards systemic resilience.Included with this publication are downloadable electronic slides and accompanying notes of each lecture for students, teachers, and public speakers around the world to be better able to understand and present climate change impacts and adaptation.

Book Description
This edited book highlights the potential and actual contributions of the sustainable management and utilization of indigenous biological resources and environment for the development of Africa. The book centers on documenting current trends and issues in the field of resource use and conservation with the view of emphasizing their benefits to the pursuit of development within the region. By documenting the array of natural resources and environment in Africa, this book addresses the topical knowledge and understanding gaps that characterize conservation (rationale for sustainable resource exploration), utilization patterns, and conservation challenges including policy status, environmental threats, impacts of tourism, reduction in food resources, etc., and their effects on the sustainable development of Africa. Through an integrated approach, the book focuses on below and above-ground biological resources and the diverse scales of environment that characterize Africa. This collection of works is very helpful for natural and social scientists, policymakers, strategists, researchers, government and non-government organizations, biodiversity and environmental managers, climate change scientists, practitioners, activists, conservationists, academics, ecologists, undergraduate and postgraduate students, and others who want to learn about and understand the best way to use and protect Africa's resources and heritage sustainably.

Book Description
not only for land use systems that depend on the regular supply of rain or irrigation water but also for the future development of natural rainforests as drought stress has been shown to a?ect tree growth and species composition in old-growth forests (Wright 1991, Walsh and Newbery 1999, Engelbrecht et al. 2007). A drought experiment conducted in a cacao agroforestry plantation showed that this plantation was surprisingly resilient to an induced drought of more than a year (Schwendenmann et al. 2009). However, droughts can have a strong impact on household incomes from agriculture, they strongly a?ect the vulnerability to poverty and thus have to be analyzed as important exogenous shocks to households, forcing them to adjust their behaviour and develop strategies to cope with these problems. The stability of rainforest margins is a critical factor in the protection of tropical rainforests (Tscharntke et al. 2007). At present, however, rainf- est margins in many parts of the tropics are far from stable, both in soc- economic and in ecological terms. For example, protected areas may attract, rather than repel, human settlement, which may be due to international donor investment in national conservation programs (Wittemeyer et al. 2008). An alternative hypothesis is that protected areas might be compromised if leakage takes place, that is, if impacts that would take place inside the restricted area are displaced to a nearby, undisturbed area (Ewers and Rodrigues 2008).
