Mexico is the fourteenth largest country in the world and ranks fifth in biodiversity. Located in the transition zone between the temperate and tropical regions of North and South America, Mexico is an important migratory corridor for wildlife and also provides wintering habitat for several species of bats, monarch butterflies, and temperate North American nesting birds.Mexico faces several challenges to wildlife management and conservation efforts. While there is increased public education and acknowledgment of the valuable benefits wildlife provides, there is still much work to do to incentivize conservation efforts. Fortunately, there is growing recognition that Mexico's wildlife resources can be a critical component in the rural economic development of the country.Bringing together an international team of wildlife experts across North America, Wildlife Ecology and Management in Mexico provides information on the status, distribution, ecological relationships, and habitat requirements and management of the most important game birds and mammals in Mexico. It also reviews current threats and challenges facing wildlife conservation as well as strategies for resolving these issues. This reference is a valuable tool for wildlife biologists, wildlife management professionals, and anyone interested in conserving Mexico's wealth of natural resources. By laying out the challenges to conservation research, editors Raul Valdez and J. Alfonso Ortega-S. hope to encourage interdisciplinary communication and collaboration across borders.

Building on the successful first edition, published in 2007, this comprehensive update to Texas Quails: Ecology and Management provides an encyclopedic overview of the research and best practices that support quail management and conservation, an accessible as well as useful guide for wildlife and natural resource professionals.Four species of quails are native to Texas—the Northern Bobwhite, Scaled Quail, Montezuma Quail, and Gambel's Quail—and hold the fascination of naturalists, hunters, and the general public. The Northern Bobwhite and Scaled Quail are of major economic significance to the state: hunters pay millions of dollars annually to lease land and construct hunting camps to support their pursuit of these birds. Gambel's Quail and Montezuma Quail are found in limited areas of southwestern Texas and represent an important barometer of rangelands and habitat conditions. In some regions, such as the brush country of South Texas or the grasslands of the Rolling Plains, quail are now an economic commodity on par with livestock and agricultural crops.Written collaboratively by leading experts, this updated edition brings the results of cutting-edge research to those who manage, enhance, and restore quail populations. This new edition will inform and serve quail management, conservation, and research priorities in Texas for decades.

The lowest stretch of the Rio Grande hosts a unique subtropical avian community, including many species not present in the United States outside of South Texas. Originally a mosaic of forest, woodland, thorn scrub, savannah, and wetlands, this land that often saw floods, droughts, heat, and occasional freezes, supported a versatile bird community. But conditions today are very different—the Rio Grande is an endangered river, and the habitats it supports are highly vulnerable. Ranch and farmlands that spread widely in the early to mid-twentieth century are suffering; forests and wetlands have declined substantially; and thorn forest habitats are experiencing significant, though less extreme, declines.Learning more about the habitats birds need necessitates knowledge of foraging requirements, patterns of habitat use, and nesting ecology to help us understand how birds are responding to these changes and to take steps to help declining species. In Changing Habitats and Birdlife of the Lower Rio Grande Valley of Texas, Timothy Brush evaluates bird species' responses to a warmer and drier climate, continued lack of riverine flooding, and rapid urban development that drives habitat destruction. He highlights sensitive riparian habitats and the avian communities most impacted by humanity and analyzes why some species are doing well while others are not.Building upon his earlier book, Nesting Birds of a Tropical Frontier: The Lower Rio Grande Valley of Texas, Brush updates the status of the Valley's breeding bird species, concluding with ongoing research and conservation needs, as well as suggestions to improve local and regional habitats and their avian communities. Conservationists and bird aficionados alike will find an informative resource in Changing Habitats and Birdlife of the Lower Rio Grande Valley of Texas.
