This convenient reference guide to the 150 most familiar and important grass species in Texas includes a line drawing and botanical description for each. "A careful morphological description is provided for each species, together with a brief account of its distribution in Texas, its habitat, and its uses. Each description is accompanied by a beautifully drawn illustration of the habit of the plant and a detail of the flower structure. . . . drawings and specific descriptions are...

For many years, brief encounters between sharks and humans could leave the latter with a vivid memory of the much-maligned fish but no convenient means of identifying it more specifically. With the publication of "The Sharks of North American Waters" in 1983, everyone from the experienced ichthyologist to the weekend angler had access to concise descriptions and accurate, detailed drawings in this handy field guide to more than one hundred species.
All species that have been reported within five hundred nautical miles of U.S. and Canadian shores (plus a few deep-water species from...

"The Birds of North Central Texas" is the culmination of a seven-year study by Warren M. Pulich, who set out to assess and evaluate the avifauna within the 25,000-square-mile area rather than to produce a field guide. With the aid of trusted observers, the author has compiled information on arrival and departure dates and peak numbers during migration for approximately 400 species.
Texas' large variety of bird species is due to the convergence of four vegetation zones in the north central region of the state. In effect, species predominating in the moister eastern portions of the region...

Texas Range Plants offers a handy and attractive identification guide for the soil conservationist, range ecologist, amateur botanist, land appraiser, college or high school student, 4-H member or leader, and rangeland manager. The book describes and illustrates the 140 grasses, forbs, shrubs, and trees that are economically important on Texas rangelands because of their important forage characteristics, poisonous attributes, or "weedy" or aggressive nature.

Bobwhite quail are one of America's favorite game birds. Healthy coveys of bobwhites indicate healthy land, and because quail hunting can bring in valuable income, landowners and game managers value these birds and encourage them wherever the habitat is suitable. Although biologists have studied bobwhites since the 1920s and have amassed an awesome base of information about this species, their knowledge has not been made widely available to landowners, hunters, and other lay readers. The questions that arise during periods of reflection after a hunt or in discussions around a campfire already...

Geo-Texas succeeds in bringing together astronomy, geology, meteorology, oceanography, and environmental studies in a highly informative, one-of-a-kind guide to Earth sciences in the Lone Star State. Eric R. Swanson draws on the latest scientific findings in treating the natural history of Texas from the oldest known rock, through the age of the dinosaurs, to the geologic present, from the early development of Texas' water and land resources to the current crisis of environmental pollution. In examining Texas natural sciences-and the abiding connection between Texans and their physical...
