This guide covers the main timber species regulated by the Convention on International Trade in Endangered Species (CITES). It provides information on the key issues regarding the implementation of the Convention for this important group of plants. Written for the non-expert, individual sections cover the species found in significant trade, with details on their distribution, uses, traded parts and derivatives, and scientific and common names.

Additional sections cover timber identification and measurement, guidance on CITES documentation and key resources.

Colorado Flora: Eastern Slope describes the remarkable flora of the state—distinctive in its altitudinal range, numerous microhabitats, and ancient and rare plants— and educates local amateurs and professionals in the recognition of vascular plant species and encourage informed stewardship of our biological heritage. When used alongside Colorado Flora: Western Slope, the full scope of the flora of the front range is at your fingertips.

The revised and updated editions reflect current taxonomic knowledge. The authors describe botanical features of this unparalleled biohistorical region and its mountain ranges, basins, and plains and discuss plant geography, giving detailed notes on habitat, ecology, and range. The keys recount interesting anecdotes and introductions for each plant family. The book is rounded out with historical background of botanical work in the state, suggested readings, glossary, index to scientific and common names, references, and hundreds of illustrations. The books also contain a new contribution from Donald R. Farrar and Steve J. Popovich on moonworts. The fourth editions of both Colorado Flora: Eastern Slope and Colorado Flora: Western Slope are ideal for both student and scientist and essential for readers interested in Colorado's plant life.

Although cacti such as the saguaro and organ pipe have come to define the Sonoran Desert for many people, they represent some 170 species of columnar cacti found in many parts of the Americas. These giant plants are so dominant in some ecosystems that many species of animals rely on them for food and shelter. They are pollinated by bats in central Mexico and Venezuela, by birds and bees in northern Mexico and Peru.

This book summarizes our current knowledge about the ecology, evolution, and conservation of columnar cacti and their vertebrate mutualists to show that the very survival of these cacti depends on animals who pollinate them and disperse their seeds. Contributors from the United States, Mexico, Venezuela, and Colombia explore aspects of geology and evolution that have forged this relationship, review findings in anatomy and physiology, and discuss recent research in population and community ecology as well as conservation issues. Ranging from the Sonoran Desert to the northern Andes, these studies reflect recent progress in understanding how abiotic and biotic factors interact to influence the evolution, distribution, and abundance of cacti and mutualists alike.

In addition, this book examines the ways in which humans, through the process of domestication, have modified these plants for economic benefit. The contributors also review phylogenetic relationships between cacti and nectar-feeding bats in an effort to understand how bat-plant interactions have influenced the evolution of diversity and ecological specialization of both. Because of the number of migratory pollinators feeding on columnar cacti, the authors make conservation recommendations aimed at preserving fully functional ecosystems in arid portions of the New World tropics and subtropics.

No other book treats the pollination ecology of cacti in such depth or offers such a wealth of up-to-date material on the nectar-feeding bats of the New World. As scientists become increasingly concerned with the need to protect biotic interactions, Columnar Cacti and Their Mutualists provides a benchmark for both conservation efforts and future research.

This engaging illustrated guidebook reveals the fascinating mosses and lichens that homeowners, outdoorspeople, and nature lovers encounter every day in Ohio and the Midwest.

In this guide to the most common and distinctive moss, liverwort, and lichen species in Ohio, readers will find concise physical descriptions, facts about natural history and ecology, and tips to distinguish look-alike species, all presented in a friendly, conversational tone.

Featuring detailed photographs of the plant and plantlike species in their natural settings, the book covers 106 mosses, thirty liverworts, and one hundred lichens and offers several avenues to match a specimen to its description page. “Where They Grow” chapters spotlight species commonly encountered on field outings, and field keys to help readers quickly identify unfamiliar samples.

While designed primarily as an identification tool, this guide also frames moss and lichen spotting in a scientific context. The two main sections—bryophytes and lichens—detail their respective taxonomic kingdoms, explain their life cycles and means of reproduction, and illustrate variation in the traits used for identification. The book is an introduction to the biology of these intriguing but too-often-overlooked organisms and a means to enjoy, identify, and catalog the biodiversity all around us.

As our world becomes increasingly urbanized, an understanding of the context, mechanisms, and consequences of city and suburban environments becomes more critical. Without a sense of what open spaces such as parks and gardens contribute, it’s difficult to argue for their creation and maintenance: in the face of schools needing resources, roads and sewers needing maintenance, and people suffering at the hands of others, why should cities and counties spend scarce dollars planting trees and preserving parks?

           

In Constructed Climates, ecologist William G. Wilson demonstrates the value of urban green. Focusing specifically on the role of vegetation and trees, Wilson shows the costs and benefits reaped from urban open spaces, from cooler temperatures to better quality ground water—and why it all matters. While Constructed Climates is a work of science, it does not ignore the social component. Wilson looks at low-income areas that have poor vegetation, and shows how enhancing these areas through the planting of community gardens and trees can alleviate social ills. This book will be essential reading for environmentalists and anyone making decisions for the nature and well-being of our cities and citizens.
