Book Description
Covering 172 species of the most significant common grasses growing in Texas, this complete update of the now-classic Common Texas Grasses: An Illustrated Guide contains range maps and color images of the inflorescences and spikelets of each species along with the detailed, black-and-white illustrations found in the original volume. Identifying descriptive text, keys to genera and species, a checklist, and a glossary round out this standard field reference for botanists, students, and naturalists.

Book Description
This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.

Book Description
The coastal prairies and marshes of the Texas Gulf Coast are among the richest grazing lands in the state. Traditionally they have been the site of some of the largest ranches in Texas; today the ranches are primarily cow-calf operations that use forage grasses as well as "tame" grasses such as Bermuda and some bluestems. This region is also an excellent natural habitat for upland game and waterfowl and is an important recreational hunting and fishing area. Urban and industrial development has increased in the region as well; since World War II the prairies and marshes have seen the greatest industrial development of any part of the state, and the effects of that development on the environment are of great concern. Grasses of the Texas Gulf Prairies and Marshes serves as a useful manual for the identification and study of grasses of the prairies and marshes adjacent to the Gulf of Mexico from northern Mexico to western Louisiana. This field guide is a systematic and descriptive treatment of the grasses found on that coastal zone and includes keys to the 98 genera and 303 species. For convenience in locating specific taxa, the grasses are listed alphabetically by genus and then by species within genus; common names are provided when they are known. Species descriptions include information on longevity, dimensions of the entire plant and of the spikelets, and descriptions of the grass's habitat and distribution and rating of its value for stock or wildlife. The notes on abundance, habitat, and distribution provide information on the ecological niche of each species. Where known, the requirements of the species, such as moisture, soil, and other environmental conditions are given. Heavily illustrated with line drawings of grass plants and plan parts, this field guide will be useful for stock raisers, wildlife managers, and environmentalists as well as grass taxonomists and range scientists.

Book Description
Invasion ecology is the study of the causes and consequences of the introduction of organisms to areas outside their native range. Interest in this field has exploded in the past few decades. Explaining why and how organisms are moved around the world, how and why some become established and invade, and how best to manage invasive species in the face of global change are all crucial issues that interest biogeographers, ecologists and environmental managers in all parts of the world. This book brings together the insights of more than 50 authors to examine the origins, foundations, current dimensions and potential trajectories of invasion ecology. It revisits key tenets of the foundations of invasion ecology, including contributions of pioneering naturalists of the 19th century, including Charles Darwin and British ecologist Charles Elton, whose 1958 monograph on invasive species is widely acknowledged as having focussed scientific attention on biological invasions.
