Half‐hourly measurements of the net exchanges of carbon dioxide and water vapor between terrestrial ecosystems and the atmosphere provide estimates of gross primary production (GPP) and evapotranspiration (ET) at the ecosystem level and on daily to annual timescales. The ratio of these quantities represents ecosystem water use efficiency. Its multiplication with mean daylight vapor pressure deficit (VPD) leads to a quantity which we call “inherent water use efficiency” (IWUE*). The dependence of IWUE* on environmental conditions indicates possible adaptive adjustment of ecosystem physiology in response to a changing environment. IWUE* is analyzed for 43 sites across a range of plant functional types and climatic conditions. IWUE* increases during short‐term moderate drought conditions. Mean annual IWUE* varied by a factor of 3 among all sites. This is partly explained by soil moisture at field capacity, particularly in deciduous broad‐leaved forests. Canopy light interception sets the upper limits to canopy photosynthesis, and explains half the variance in annual IWUE* among herbaceous ecosystems and evergreen needle‐leaved forests. Knowledge of IWUE* offers valuable improvement to the representation of carbon and water coupling in ecosystem process models.

Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world's leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world's major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.

A concise but comprehensive introduction to the biology of coastal sand dunes. The emphasis in this book is on the organisms that dominate this predominantly marine environment, although pollution, conservation, management and experimental aspects are considered.

Advances in Geosciences is the result of a concerted effort in bringing the latest results and planning activities related to earth and space science in Asia and the international arena. The volume editors are all leading scientists in their research fields covering five sections: Solid Earth (SE), Solar Terrestrial (ST), Planetary Science (PS), Hydrological Science (HS), and Oceans and Atmospheres (OA). The main purpose is to highlight the scientific issues essential to the study of earthquakes, tsunamis, climate change, drought, flood, typhoons, space weathers, and planetary exploration.This volume is abstracted in NASA's Astrophysics Data System: http://ads.harvard.eduContents:Sabah Shoreline Management Plan (F Jakobsen et al.)Potential for Sulfide Mineral Deposits in Australian Waters (T F McConachy)Local to Long-Range Dust Transport over Central Eastern Australia (M S Speer L M Leslie)Interannual Variations in Pacific SST Deviations through AVHRR (J Yu P Gloersen)An Investigation of Winter Rainfall and Snowfall in the Mountain and Coast (H Choi)Impact of Regional Circulation and Heat Budget to Tropical Night (H Choi D S Choi)and other papersReadership: Academics, researchers and postgraduate students in geosciences.

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.

Interactions between plants and animals are incredibly diverse and complex and span terrestrial, atmospheric and aquatic environments. The last decade has seen the emergence of a vast quantity of data on the subject and there is now a perceived need among both teachers and undergraduate students for a new textbook that incorporates the numerous recent advances made in the field. The book is intended for use by advanced level undergraduate and beginning graduate students, taking related courses in wider ecology degree programmes. Very few books cover this subject and those that do are out of date.
