Book Description
This book is open access under a CC BY 4.0 license. This volume focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date. Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.

Book Description
The most feared attribute of the human pathogen Vibrio cholerae is its ability to cause outbreaks that spread like wildfire, completely overwhelming public health systems and causing widespread suffering and death. This volume starts with a description of the contrasting patterns of outbreaks caused by the classical and El Tor biotypes of V. cholerae. Subsequent chapters examine cholera outbreaks in detail, including possible sources of infection and molecular epidemiology on three different continents, the emergence of new clones through the bactericidal selection process of lytic cholera phages, the circulation and transmission of clones of the pathogen during outbreaks and novel approaches to modeling cholera outbreaks. A further contribution deals with the application of the genomic sciences to trace the spread of cholera epidemics and how this information can be used to control cholera outbreaks. The book closes with an analysis of the potential use of killed oral cholera vaccines to stop the spread of cholera outbreaks.

Book Description
"This volume applies insights drawn from the theories and methods of landscape archaeology to contribute to our understanding of the nature if West African societies in the Atlantic Era (17th-19th Centuries AD). The authors adopt a briad set of methods and approaches to tackle how the nature and structures of African political and social relations changed across regions in this period. This is only the second volume in a decade to focus on the archeology of this period in West Africa, and the first volume in sub-Saharan Africanist archeology to be focused in the recent past in oue sub-region of the continent from a coherent methodological and theoretical standpoint"--Provided by publisher.

Book Description
Drawing on many years of African experience, John Reader has written a book of startling grandeur and scope that recreates the great panorama of African history, from the primeval cataclysms that formed the continent to the political upheavals facing much of the continent today. Reader tells the extraordinary story of humankind's adaptation to the ferocious obstacles of forest, river and desert, and to the threat of debilitating parasites, bacteria and viruses unmatched elsewhere in the world. He also shows how the world's richest assortment of animals and plants has helped - or hindered - human progress in Africa.

Book Description
Invasive species have come to dominate 3% of the Earth’s ice-free surface, constituting one of the most serious ecological and economic threats of the new millennium, and freshwater systems are particularly vulnerable. This book examines the identity, distribution, and impact of freshwater non-indigenous species and the dynamics of their invasion. It focuses on old and new invaders and provides a starting point for further research.
