Texas Waterfowl
Author: William P. Johnson
Publisher: Texas A&M University Press
ISBN: 1603448071
Category : Nature
Languages : en
Pages : 194
Book Description
In this beautifully illustrated guide, two practicing wildlife biologists describe the life histories of forty-five species of ducks, geese, and swans that occur in Texas. For common species and those that breed in the state, each account begins with an interesting fact (such as, “Red-breasted Mergansers have been clocked at over 80 mph, the fastest recorded flight speed for a duck . . .”) and provides information on Texas distribution and harvest, population status, diet, range and habitats, reproduction, and appearance. Exquisite photographs, informative distribution maps, and a helpful source list accompany the species descriptions, and the book offers a glossary and full bibliography for those who want to explore the literature further. With the degradation and disappearance of the inland and coastal habitats that these birds depend upon, the natural history of these waterfowl species provides a vital reminder of the interconnectedness and crucial importance of all wetlands. Birders, biologists, landowners, hunters, outdoor enthusiasts, and all those interested in the health and preservation of our coastal and inland wetland resources will enjoy and learn from this book.

Biodiversity in Agroecosystems
Author: Wanda W. Collins
Publisher: CRC Press
ISBN: 9781420049244
Category : Technology & Engineering
Languages : en
Pages : 352
Book Description
between the diversity of plant and animal species and host/dependent agricultural systems. Biodiversity in Agroecosystems shows how biodiversity can be thought of not only as the rich make-up of a great number of related and competing species within an ecologically defined community, but also as the robust behavior and resilience of those species over time and as the endurance of their eco-community. This book brings to the fore new research on biodiversity in agricultural ecosystems at both micro and macro levels, heretofore available only in journals and proceedings papers.
