Book Description
A marvelously illustrated reference to the natural wonders of one of the most spectacular places on earth Separated from Africa’s mainland for tens of millions of years, Madagascar has evolved a breathtaking wealth of biodiversity, becoming home to thousands of species found nowhere else on the planet. The New Natural History of Madagascar provides the most comprehensive, up-to-date synthesis available of this island nation’s priceless biological treasures. Now fully revised and expanded, this beautifully illustrated compendium features contributions by more than 600 globally renowned experts who cover the history of scientific exploration in Madagascar, as well as the island’s geology and soils, climate, forest ecology, human ecology, marine and coastal ecosystems, plants, invertebrates, fishes, amphibians, reptiles, birds, and mammals. This invaluable two-volume reference also includes detailed discussions of conservation efforts in Madagascar that showcase several successful protected area programs that can serve as models for threatened ecosystems throughout the world. Provides the most comprehensive overview of Madagascar’s rich natural historyCoedited by 18 different specialistsFeatures hundreds of new contributions by world-class expertsIncludes hundreds of new illustrationsCovers a broad array of topics, from geology and climate to animals, plants, and marine lifeSheds light on newly discovered species and draws on the latest scienceAn essential resource for anyone interested in Madagascar or tropical ecosystems in general, from biologists and conservationists to ecotourists and armchair naturalists

Book Description
The Madagascar and Indian Ocean Islands biodiversity hotspot is renowned for its high levels of species diversity and endemism. Yet despite many hypotheses and a considerable literature, we still know relatively little about the mechanisms of species diversification within the region. Until recently, the major role for high levels of species diversity was attributed solely to breakup of East Gondwana and the isolation of Madagascar and India (120-160Mya). However, an increasing number of studies, employing recent advances in analytical methods, have shown that the origin for many groups post-dates the isolation of Madagascar. Furthermore, Madagascar is embedded in a wider geographical setting of oceanic and microcontinental islands that vary distinctly in origin, age and structure, and that are also home to highly diverse flora and fauna assemblages. Most of these islands are young (2-10My) and the high levels of endemism on these islands therefore can't be explained by Gondwanan vicariance, but only by recent long distance dispersal followed by extensive in-situ diversification processes. In addition, some groups of organisms show higher levels of diversity on young volcanic islands than on Madagascar, which runs counter to expectations given the greater surface area and habitat diversity of Madagascar. Taking into account the disparity in geological ages among the land fragments in the Indian Ocean, theory suggests that diversification on geologically young islands would have proceeded via high levels of diversification rates and rapid shifts over time after new ranges and habitat became available upon colonization. In this thesis we compare major plant lineages (Asteraceae, Myrsinaceae, Monimiaceae) that have undergone extensive diversification in the region. In each of these families we selected highly speciose genera that are characterized by single island endemism, phenotypic diversity and presence on Madagascar and a range of Indian Ocean islands. We found evidence of significant shifts in diversification rates and repeated long distance dispersals to Indian Ocean islands where Madagascar played a central role as a disperser source...

Book Description
Oceanography and Marine Biology: An Annual Review remains one of the most cited sources in marine science and oceanography. The ever-increasing interest in work in oceanography and marine biology and its relevance to global environmental issues, especially global climate change and its impacts, creates a demand for authoritative refereed reviews summarizing and synthesizing the results of both historical and recent research. This Volume celebrates 60 years of OMBAR, over which time it has been an essential reference for research workers and students in all fields of marine science. The peer-reviewed contributions in Volume 60 are available to read Open Access via this webpage and on OAPEN. If you are interested in submitting a review for consideration for publication in OMBAR, please email the Editor-in-Chief, Stephen Hawkins ([email protected]) for Volume 61. For Volume 62 onwards, please email the new co-Editors in Chief, Dr Peter Todd ([email protected]) and Dr Bayden Russell ([email protected]). Volume 60 features an editorial on the UN Decade of Ocean Science and goes on to consider such diverse topics as Cenozoic tropical marine biodiversity, blue carbon ecosystems in Sri Lanka, marine litter and microplastics in the Western Indian Ocean, and the ecology and conservation status of the family Syngnathidae in southern and western Africa. This volume also contains a retrospective Prologue on the evolution of OMBAR and pays tribute to one of its early Editors in Chief, Margaret Barnes, by providing an update on her review in OMBAR of the stalked barnacle Pollicipes. Supplementary online videos as well as additional Tables and Appendices are available on the Support Tab of the book's Routledge webpage. An international Editorial Board ensures global relevance and expert peer review, with editors from Australia, Canada, Hong Kong, Ireland, Singapore and the UK. The series volumes find a place in the libraries of not only marine laboratories and oceanographic institutes, but also universities worldwide.

Book Description
One of the main reasons cited for inadequate representation of biodiversity in the development processes is a lack of readily available information on inland water taxa. In response to this need for basic for information on species, the IUCN Species Programme conducted a regional assessment of the status and distribution of 2,261 taxa of freshwater fishes, molluscs, odonates, crabs and selected families of aquatic plants from throughout central Africa. This study is based on the collation and analysis of existing information, and the knowledge of regional experts.

Book Description
This book is about phylogenetic diversity as an approach to reduce biodiversity losses in this period of mass extinction. Chapters in the first section deal with questions such as the way we value phylogenetic diversity among other criteria for biodiversity conservation; the choice of measures; the loss of phylogenetic diversity with extinction; the importance of organisms that are deeply branched in the tree of life, and the role of relict species. The second section is composed by contributions exploring methodological aspects, such as how to deal with abundance, sampling effort, or conflicting trees in analysis of phylogenetic diversity. The last section is devoted to applications, showing how phylogenetic diversity can be integrated in systematic conservation planning, in EDGE and HEDGE evaluations. This wide coverage makes the book a reference for academics, policy makers and stakeholders dealing with biodiversity conservation.

Book Description
This assessment is the first overview of the conservation status of 877 northern African freshwater species belonging to five taxonomic groupsfish, molluscs, dragonflies and damselflies, freshwater crabs and aquatic plantsin accordance with the IUCN regional Red List guidelines. Species at risk of regional extinction are mapped and conservation measures are proposed to reduce the probability of future declines.
