Guide To The Vascular Flora Of Howell Woods Johnston County Nc

Comprehensive manual for understanding and carrying out marine mammal rescue activities for stranded seals, manatees, dolphins, whales, or sea otters.

Climbers, such as lianas and vines, are important constituents of tropical forests and perhaps the single most important physiognomic characteristic differentiating tropical from temperate forests, occurring on nearly 50% of forest trees in Central and South America. Despite their widespread nutritional and medicinal use, lianas remain poorly understood ecologically. Tendrillate Climbers offers comprehensive coverage of all of the tendrillate lianas of Costa Rica and most of the tendrillate lianas of Central America. This unique reference provides Excellent keys to families and separate keys to genera and species State-of-the-art nomenclature and lists of synonymy when other scientific names have been published or used informally Each species illustrated by the author’s hand-drawn line art An invaluable addition to our understanding of tropical forests, the book offers new information as well as information brought together from dispersed publications and unpublished lists and reports. In these times of habitat fragmentation and species loss, this data is a significant contribution to the biological research that is thriving in Central America, especially Costa Rica. Tendrillate Climbers fills a major gap in the botanical literature. Its high level of scholarship and comprehensive coverage will astonish the tropical botanists, forestry scientists, ecologists, biologists, and horticulturalists who will want it as a reference for their continued work on this neglected group of plants.

This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

Seagrasses are a vital and widespread but often overlooked coastal marine habitat. This volume provides a global survey of their distribution and conservation status.
