Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Fish and Wildlife Service (USFWS) recognizes Tamaulipan brushland as a unique ecosystem that is found only in the Lower Rio Grande Valley (LRGV) of south Texas in the United States and northeastern Mexico. The LRGV is not really a valley but a delta, or a fertile plain, that slopes away from the Rio Grande (Johnston 1963; Rio Grande Valley Chamber of Commerce 1983; Lonard et al. 1988). The combination of climate, vegetation, and associated wildlife is unlike that in any other region of the United States. The vegetation is influenced by edaphic factors, and plant distribution can be correlated with geologic formations (Clover 1937). Characteristic vegetation of Tamaulipan brushland is dense and thorny. The most luxuriant brush is found on alluvial soil of the Rio Grande floodplain (Blair 1950), and large cedar elms (Ulmus crassifolla) dominate in some mesic areas. Vegetation in the xeric upland areas is mostly spiny shrubs and stunted trees (Clover 1937). A few characteristic plant species comprise the bulk of the brush vegetation. At present, some of the ubiquitous woody plant species are (Blair 1950): Texas ebony (Pithecello)- bium flexicaule); retama (Parkinsonia aculeata); granj eno (Celtis pallida); huisache (Acacia srnallii); prickly pear (Opuntia lindheimeri); and mesquite (Prosopis glaiidulosa) - although prevalence of one mesquite may be due to human land abuse (Archer et al. 1988).

This book was released on 2017-02-09 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Authored by some of the state’s top wildlife scientists, The Upland and Webless Migratory Game Birds of Texas presents the most up-to-date and comprehensive information covering twenty-one species of game birds. Ranging from the most well-known, like the Wild Turkey and Mourning Dove, to the marsh-loving rails and other more elusive species, these birds have widespread appeal among both hunters and birders and underscore the diverse challenges facing wildlife scientists, land managers, and conservationists in Texas today. From cultural significance to taxonomy and evolutionary history, this volume provides a wealth of background information on these species. Additionally, the book offers illustrated species accounts, detailed range maps, and information about habitat and management requirements, hunting regulations, and research priorities. Readers will gain a deeper understanding of these game birds and the array of terrestrial and wetland landscapes key to their survival. This will serve as a convenient and thorough reference volume for wildlife biologists and enthusiasts, as well as landowners and hunters.

Available in PDF, EPUB and Kindle. Book excerpt: The story behind the birds everyone wants to see Halfway between Dallas and Mexico City, along the last few hundred miles of the Rio Grande, lies a subtropical outpost where people come from all over the world to see birds. Located between the temperate north and the tropic south, with desert to the west and ocean to the east, the Lower Rio Grande Valley of Texas provides habitat for a variety of birds seen nowhere else in the United States. If you want to see a Hooked-billed Kite, Muscovy Duck, or Altamira Oriole, this is the place. Drawing on years of personal observation and study, Timothy Brush has written a classic work of natural history about the little-known breeding bird communities of the Valley and the diversity of nesting strategies and behaviors that can be seen. Brush estimates that there are more than 150 current breeding species in the Lower Rio Grande Valley. In Nesting Birds of a Tropical Frontier, he describes the habits, distribution, changes in occurrence, and general outlook of these as well as former breeders, concentrating on Valley specialties and other birds of particular interest in the Valley. The species are all dependent upon appropriate habitat, from riparian forest to mesquite savannah, and Brush describes the history of these habitats and the special features that keep the birds coming. He also discusses conservation and the need for both large-scale land acquisitions by public and private groups and small-scale restoration through urban parks and individual landscaping. Art by Gerald Sneed and color photographs by several of Texas’ top nature photographers show off some of the Valley’s famous birds. Historical maps of vegetation and geology help us gain a better perspective on the changes that have taken place along the Rio Grande and on the breeding bird communities of the U.S.–Mexico frontier.
Download or read book Ecology of North America written by Brian R. Chapman and published by John Wiley & Sons. This book was released on 2015-04-09 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: North America contains an incredibly diverse array of naturalenvironments, each supporting unique systems of plant and animallife. These systems, the largest of which are biomes, formintricate webs of life that have taken millennia to evolve. Thisrichly illustrated book introduces readers to this extraordinaryarray of natural communities and their subtle biological andgeological interactions. Completely revised and updated throughout, the second edition ofthis successful text takes a qualitative, intuitive approach to thesubject, beginning with an overview of essential ecological termsand concepts, such as competitive exclusion, taxa, niches, andsuccession. It then goes on to describe the major biomes andcommunities that characterize the rich biota of the continent,starting with the Tundra and continuing with Boreal Forest,Deciduous Forest, Grasslands, Deserts, Montane Forests, andTemperature Rain Forest, among others. Coastal environments,including the Laguna Madre, seagrasses, Chesapeake Bay, and barrierislands appear in a new chapter. Additionally, the book covers manyunique features such as pitcher plant bogs, muskeg, the polar icecap, the cloud forests of Mexico, and the LaBrea tar pits.“Infoboxes” have been added; these include biographiesof historical figures who provided significant contributions to thedevelopment of ecology, unique circumstances such as frogs andinsects that survive freezing, and conservation issues such asthose concerning puffins and island foxes. Throughout the text,ecological concepts are worked into the text; these includebiogeography, competitive exclusion, succession, soil formation,and the mechanics of natural selection. Ecology of North America 2e is an ideal first text forstudents interested in natural resources, environmental science,and biology, and it is a useful and attractive addition to thelibrary of anyone interested in understanding and protecting thenatural environment.

Available in PDF, EPUB and Kindle. Book excerpt: The Santa Ana National Wildlife Refuge lies on the northern bank of the Rio Grande in South Texas, about seventy miles upriver from the Gulf of Mexico. In Border Sanctuary, M.J. Morgan uncovers how 2,000 acres of rare subtropical riparian forest came to be preserved in a region otherwise dramatically altered by human habitation. The story she tells begins and ends with the efforts of the Rio Grande Valley Nature Club to protect one of the last remaining stopovers for birds migrating north from Central and South America. In between, she reconstructs a two hundred-year human and environmental history of the original “two square leagues” of the Santa Ana land grant and of the Mexican and Tejano families who lived on, worked, and ultimately helped preserve this forest on the river’s edge. As border issues continue to present serious challenges for Texas and the nation, it is especially important to be reminded of the deep connection between the region’s human and natural history from the long perspective Morgan provides here.
