The Laguna Madre is the only hypersaline coastal lagoon on the North American continent and only one of five worldwide. The lagoon is renowned for its vast seagrass meadows, huge wintering redhead population, and bountiful fishing grounds. In 2000, the Nature Conservancy, whose mission is the conservation of biodiversity through protection of habitat, recognized the need to amass all known information about the Laguna Madre and implement a science-based conservation agenda. From those efforts came the first edition of this book. Now completely revised and updated, this second edition of The Laguna Madre of Texas and Tamaulipas is the culmination of two decades of additional research and continued conservation efforts in the region. Nearly 100 years of literature on the Laguna Madre and surrounding environments has been synthesized here. With 150 figures and illustrations, the book takes a broad and comprehensive look at both the Texan and Tamaulipan Laguna Madre. The value of this book for scientists, conservationists, resource managers, and policy makers involved in the future of the Texas and Mexico coasts is clear. Coastal residents, birders, anglers, and nature lovers who want to learn about and take care of the Laguna Madre will find this to be an indispensable guide.

Virtually every area of research associated with sharks and their relatives has been strongly impacted by the revolutionary growth in technology. The questions we can now ask are very different than those reported even two decades ago. Modern immunological and genetic techniques, satellite telemetry and archival tagging, modern phylogenetic analysis, GIS, and bomb dating, are just a few of the techniques and procedures that have become a part of our investigative lexicon. A modern synthesis of the biology of Chondrichthyans, Biology of Sharks and Their Relatives, Second Edition discusses significant advances in the development and application of new molecular techniques to the understanding of the phylogenetic relationships among and between these groups. The book considers the effect of global changes on the status of sharks and their relatives, and how advances in technology and analytical techniques have changed not only how we approach problem solving and scientific investigations, but how we formulate questions. The book also introduces applications of new and novel laboratory devices, techniques, and field instruments. This second edition of the award winning and groundbreaking original exploration of the fundamental elements of the taxonomy, systematics, physiology, and ecology of sharks, skates, rays, and chimera, presents cohesive and integrated coverage of key topics and discusses technological advances used in modern shark research. Offering a well-rounded picture for students and researchers, and far above competitors in scope and research, this new volume holds a wealth of data on the current status of Chondrichthyan research and provides the basis and springboard for original research.

The Gulf of Mexico is an open and dynamic marine ecosystem rich in natural resources but heavily impacted by human activities, including agricultural, industrial, commercial and coastal development. The Gulf of Mexico has been continuously exposed to petroleum hydrocarbons for millions of years from natural oil and gas seeps on the sea floor, and more recently from oil drilling and production activities located in the water near and far from shore. Major accidental oil spills in the Gulf are infrequent; two of the most significant include the Ixtoc I blowout in the Bay of Campeche in 1979 and the Deepwater Horizon Oil Spill in 2010. Unfortunately, baseline assessments of the status of habitats and biota in the Gulf of Mexico before these spills either were not available, or the data had not been systematically compiled in a way that would help scientists assess the potential short-term and long-term effects of such events. This 2-volume series compiles and summarizes thousands of data sets showing the status of habitats and biota in the Gulf of Mexico before the Deepwater Horizon Oil Spill. Volume 2 covers historical data on commercial and recreational fisheries, with an analysis of marketing trends and drivers; ecology, populations and risks to birds, sea turtles and marine mammals in the Gulf; and diseases and mortalities of fish and other animals that inhabit the Gulf of Mexico.
