Tripping from the Fall Line


Book Description

"Emanating from the Fall Line city of Baltimore, site of the 2015 GSA Annual Meeting, these trips reflect the diversity of geological features in the mid-Atlantic region including the Piedmont, Appalachian Mountains, and Coastal Plain, and the importance of geology on the development and construction of the Baltimore-Washington, D.C., metropolitan area"--

Costa Rican Ecosystems


Book Description

In the more than thirty years since the publication of Daniel H. Janzen’s classic Costa Rican Natural History, research in this small but astonishingly biodiverse, well-preserved, and well-studied Latin American nation has evolved from a species-level approach to the study of entire ecosystems. And from the lowland dry forests of Guanacaste to the montane cloud forests of Monteverde, from the seasonal forests of the Central Valley to the coastal species assemblages of Tortuguero, Costa Rica has proven to be as richly diverse in ecosystems as it is in species. In Costa Rican Ecosystems, Maarten Kappelle brings together a collection of the world’s foremost experts on Costa Rican ecology—outstanding scientists such as Daniel H. Janzen, Jorge Cortés, Jorge A. Jiménez, Sally P. Horn, Robert O. Lawton, Quírico Jiménez M., Carlos Manuel Rodríguez, Catherine M. Pringle, and Eduardo Carrillo J., among others—to offer the first comprehensive account of the diversity, structure, function, uses, and conservation of Costa Rica’s ecosystems. Featuring a foreword and introductory remarks by two renowned leaders in biodiversity science and ecological conservation, Thomas E. Lovejoy and Rodrigo Gámez Lobo, in addition to chapters highlighting the geology, soils, and climate of Costa Rica, as well as the ecosystems of its terrestrial, freshwater, and marine habitats, and including previously unpublished information on Isla del Coco, this beautiful color-illustrated book will be an essential reference for academic scientists, students, natural history guides, conservationists, educators, park guards, and visitors alike.




The Routledge Companion to Sexuality and Colonialism


Book Description

Unique in its global and interdisciplinary scope, this collection will bring together comparative insights across European, Ottoman, Japanese, and US imperial contexts while spanning colonized spaces in Latin America, the Caribbean, Africa, the Indian Ocean, the Middle East, and East and Southeast Asia. Drawing on interdisciplinary perspectives from cultural, intellectual and political history, anthropology, law, gender and sexuality studies, and literary criticism, The Routledge Companion to Sexuality and Colonialism combines regional and historiographic overviews with detailed case studies, making it the key reference for up-to-date scholarship on the intimate dimensions of colonial rule. Comprising more than 30 chapters by a team of international contributors, the Companion is divided into five parts: Directions in the study of sexuality and colonialism Constructing race, controlling reproduction Sexuality in law Subjects, souls, and selfhood Pleasure and violence. The Routledge Companion to Sexuality and Colonialism is essential reading for students and researchers in gender, sexuality, race, global studies, world history, Indigeneity, and settler colonialism.




Voltage-Gated Calcium Channels


Book Description

This book covers the tremendous progress in the current understanding of the molecular physiology of voltage-gated calcium channels. This book includes unparalleled insights into structural features of calcium channels due to X-ray crystallography and cryo-EM, which in turn yielded critical information into how these channels function under normal and pathophysiological conditions, and how they interact with calcium channel therapeutics. The chapters investigate how, with the advent of high throughput genome sequencing, numerous mutations in various calcium channel genes have been identified in patients with neurological, cardiovascular, neuropsychiatric and other disorders. This is further complemented through a much larger in vivo toolkit such as knock-out and knock-in mice. The chapters further discuss the increased complexity of calcium channel physiology that arises from mRNA editing and splicing. Finally, the book also provides an overview of the updated research on calcium channel inhibitors that can be used both in vivo and in vitro, and which may serve as a spring board for new calcium channel therapeutics for human disease. Voltage-Gated Calcium Channels is useful for academic researchers at all levels in neuroscience, biophysics, cell biology and drug discovery.
