Book Description
This unique, multilingual, encyclopedic dictionary in two volumes covers terms regularly used in landscape and urban planning, as well as environmental protection. The languages are American and British English, Spanish (with many Latin-American equivalents), French, and German. The encyclopedia also provides various interpretations of the terms at the planning, legal or technical level, which make its meaning more precise and its usage clearer.

Book Description
Mexico is among the richest countries in the world in terms of the number of native animal and plant species. Found in a wide variety of habitats--from alpine meadows and tropical forests to vast stretches of desert and isolated pockets of biogeographical uniqueness--these species comprise a fascinating, important, and vastly underutilized biological laboratory. This volume presents a collection of selected papers that explore this marvelous biological abundance. The book is divided into six parts. The first section sets the stage with geological and paleobotanical overviews; the succeeding five sections employ a strong taxonomic base to document species richness, endemism and distribution for animals and plants, followed by reviews of contrasting ecosystems and plants that are closely associated with humans. The last section summarizes the disheartening rate of habitat destruction which threatens to diminish this diversity. In addition to the purely scientific value of this important work, it provides the much-needed basic data that will help conservation policymakers assess and respond to Mexico's ecological evolution.

Book Description
The objectives of this volume are to present an up-to-date (literature survey up to 2001) account of the biology of Artemia focusing particularly upon the major advances in knowledge and understanding achieved in the last fifteen or so years and emphasising the operational and functional linkage between the biological phenomena described and the ability of this unusual animal to thrive in extreme environments. Artemia is a genus of anostracan crustaceans, popularly known as brine shrimps. These animals are inhabitants of saline environments which are too extreme for the many species which readily predate them if opportunity offers. They are, thus, effectively inhabitants of extreme (hypersaline) habitats, but at the same time are able to tolerate physiologically large changes in salinity, ionic composition, temperature and oxygen tension. Brine shrimp are gener ally thought of as tropical and subtropical, but are also found in regions where temperatures are very low for substantial periods such as Tibet, Siberia and the Atacama desert. They have, thus, great powers of adaptation and are of interest for this capacity alone. The earliest scientific reference to brine shrimp is in 1756, when Schlosser reported their existence in the saltpans of Lymington, England. These saltpans no longer exist and brine shrimp are not found in Britain today. Later, Linnaeus named the brine shrimp Cancer salinus and later still, Leach used the name Artemia salina. The strong effect which the salinity of the medium exerts on the morphological development of Artemia is now widely recognised.

Book Description
Though seasonally dry tropical forests are equally as important to global biodiversity as tropical rainforests, and are one of the most representative and highly endangered ecosystems in Latin America, knowledge about them remains limited because of the relative paucity of attention paid to them by scientists and researchers and a lack of published information on the subject. Seasonally Dry Tropical Forests seeks to address this shortcoming by bringing together a range of experts in diverse fields including biology, ecology, biogeography, and biogeochemistry, to review, synthesize, and explain the current state of our collective knowledge on the ecology and conservation of seasonally dry tropical forests. The book offers a synthetic and cross-disciplinary review of recent work with an expansive scope, including sections on distribution, diversity, ecosystem function, and human impacts. Throughout, contributors emphasize conservation issues, particularly emerging threats and promising solutions, with key chapters on climate change, fragmentation, restoration, ecosystem services, and sustainable use. Seasonally dry tropical forests are extremely rich in biodiversity, and are seriously threatened. They represent scientific terrain that is poorly explored, and there is an urgent need for increased understanding of the system's basic ecology. Seasonally Dry Tropical Forests represents an important step in bringing together the most current scientific information about this vital ecosystem and disseminating it to the scientific and conservation communities.

Book Description
Predictions about where different species are, where they are not, and how they move across a landscape or respond to human activities -- if timber is harvested, for instance, or stream flow altered -- are important aspects of the work of wildlife biologists, land managers, and the agencies and policymakers that govern natural resources. Despite the increased use and importance of model predictions, these predictions are seldom tested and have unknown levels of accuracy.Predicting Species Occurrences addresses those concerns, highlighting for managers and researchers the strengths and weaknesses of current approaches, as well as the magnitude of the research required to improve or test predictions of currently used models. The book is an outgrowth of an international symposium held in October 1999 that brought together scientists and researchers at the forefront of efforts to process information about species at different spatial and temporal scales. It is a comprehensive reference that offers an exhaustive treatment of the subject, with 65 chapters by leading experts from around the world that: review the history of the theory and practice of modeling and present a standard terminology examine temporal and spatial scales in terms of their influence on patterns and processes of species distribution offer detailed discussions of state-of-the-art modeling tools and descriptions of methods for assessing model accuracy discuss how to predict species presence and abundance present examples of how spatially explicit data on demographics can provide important information for managers An introductory chapter by Michael A. Huston examines the ecological context in which predictions of species occurrences are made, and a concluding chapter by John A. Wiens offers an insightful review and synthesis of the topics examined along with guidance for future directions and cautions regarding misuse of models. Other contributors include Michael P. Austin, Barry R. Noon, Alan H. Fielding, Michael Goodchild, Brian A. Maurer, John T. Rotenberry, Paul Angermeier, Pierre R. Vernier, and more than a hundred others.Predicting Species Occurrences offers important new information about many of the topics raised in the seminal volume Wildlife 2000 (University of Wisconsin Press, 1986) and will be the standard reference on this subject for years to come. Its state-of-the-art assessment will play a key role in guiding the continued development and application of tools for making accurate predictions and is an indispensable volume for anyone engaged in species management or conservation.

Book Description
The essential reference book for anyone working with trees in Guatemala, including foresters, ecologists, botanists, wildlife biolgists, students, tree enthusiasts, and backyard gardeners. This work describes over 2,300 species and varieties of trees found in Guatemala, both native and introduced, aided by more than 930 detailed drawings. A glossary of botanical terms, with illustrations, are included to clarify the terms used.Trees of Guatemala is the most useful book any plant scientist or ecologist in Guatemala can own, covering both native and introduced species. The volume includes comprehensive botanical information for the expert, and a wealth of information on the ecology, distribution and uses of Guatemalan trees for the non-botanist. A unified summary for each species is designed to help the plant enthusiast, whether identifying trees in gardens, parks, along roadsides or in native forests.Tracey Parker, PhD, forest ecologist, environmental consultant, professor and photographer, holds a bachelor's degree in forestry from Colorado State University, and masters and doctorate from the University of Idaho.
