Habitat loss and degradation are perceived to be one of the main factors threatening biodiversity through detrimental effects on species and populations. These processes reduce habitat availability, increase isolation and generate patchy environments, which reduces species richness, population genetic diversity, and modifies community structure. The loss of biodiversity associated with habitat alteration is particularly problematic in forest habitats, because forests are one of the most species-rich habitat types. The conservation implications have become greater with evidence that climate change may exacerbate and speed up ongoing processes. This book focuses on topics that include niche restriction and conservatism in a neotropical psittacine; consequences for distribution patterns of specialist fauna; and paths to habitat loss in European Atlantic heathlands.
This book is the seventh in a series of titles from the National Research Council that addresses the effects of exposure to low dose LET (Linear Energy Transfer) ionizing radiation and human health. Updating information previously presented in the 1990 publication, Health Effects of Exposure to Low Levels of Ionizing Radiation: BEIR V, this book draws upon new data in both epidemiologic and experimental research. Ionizing radiation arises from both natural and man-made sources and at very high doses can produce damaging effects in human tissue that can be evident within days after exposure. However, it is the low-dose exposures that are the focus of this book. So-called “late” effects, such as cancer, are produced many years after the initial exposure. This book is among the first of its kind to include detailed risk estimates for cancer incidence in addition to cancer mortality. BEIR VII offers a full review of the available biological, biophysical, and epidemiological literature since the last BEIR report on the subject and develops the most up-to-date and comprehensive risk estimates for cancer and other health effects from exposure to low-level ionizing radiation.

This book seeks to answer to a central international politics: why do great powers rise and fall? It provides an innovative argument about how domestic political institutions are the key to a state's ability to amass power and influence in the international system. This text also offers a sweeping historical analysis of democratic and autocratic competitors from ancient Greece through the Cold War. This book employs a unique framework to understand and analyze the state of today's competition between the democratic United States and its autocratic competitors, Russia and China.
Emotion (or affect) is a cross-disciplinary subject in psychology. Psychology Library Editions: Emotion makes available again twelve previously out-of-print titles that were originally published between 1976 and 1999, either as a set or as individual volumes, in your choice of print or ebook. Written by a range of authors from diverse backgrounds and spanning different areas of psychology, such as clinical, cognitive, developmental and social, the volumes feature a variety of approaches and topics. This is a great opportunity to trace the development of research in emotion from a number of different perspectives.
