"Wetland use and selection by species of waterbirds (shorebirds, wading birds, gulls, terns, grebes, cormorants, and pelicans) between the Rio Grande and Galveston Bay in coastal Texas were studied during September and November of 1991-92 and during January and March of 1992-93. Based on a stratified (by dominant land use) random sample of 64.75-ha plots, 88 species of waterbirds using wetlands were observed. Ranks of density and proportion of feeding bird indicated that cormorants and pelicans preferred wetlands with less than 30% vegetation. Gulls, terns, and skimmers preferred certain types of estuarine and lacustrine wetlands with less than 30% vegetation, especially estuarine subtidal rock bottom rubble types. Grebes and rails selectively used palustrine aquatic-bed rooted vascular and unconsolidated bottom mud wetland types. Herons, egrets, and bitterns preferred certain types of lacustrine and estuarine wetlands. Shorebirds used estuarine intertidal wetlands. Waterbird management should focus on 26 of the 82 wetland types that we prioritized in the coastal plains of Texas. Management should focus on protecting, enhancing, or restoring complexes of various wetland types, especially estuarine aquatic-bed and intertidal unconsolidated substrate types"--Page 1

Consciously or not, wildlife managers generally act from a theoretical basis, although they may not be fully versed in the details or ramifications of that theory. In practice, the predictions of the practitioners sometimes prove more accurate than those of the theoreticians. Practitioners and theoreticians need to work together, but this proves difficult when new management ideas and cutting-edge ecological theory are often published in separate scientific outlets with distinctly different readerships. A compilation of the scientific papers presented at the Caesar Kleberg Wildlife Research Institute's 25th Anniversary Conference of April 2006, Wildlife Science: Linking Ecological Theory and Management Applications brings together these two often separate approaches to elucidate the theoretical underpinnings of wildlife management and to apply evolving ecological concepts to changes and adaptations in management practices. Gathering many of the best and greatest minds in wildlife science, this volume addresses the critically important theme of linking ecological theory and management applications. Divided into five parts, the first two parts deal with the landscape ecology of birds and mammals respectively, demonstrating the need for applied theory in gamebird management and the preservation of the cougar. Part three highlights the role of climate when applying ecological theory to habitat management and discusses the emergence of ecosystem management in managing wildlife at the ecosystem scale. Part four considers the management of wildlife disease and reveals the increasing importance of genetics in conservation and ecology. Finally, the economic and social issues affecting wildlife science round out the coverage in part five. Applying emerging ecological theory for the advancement of wildlife management, Wildlife Science: Linking Ecological Theory and Management Applications provides a long awaited cooperative look at the future of ecosystem management.

This book is open access under a CC BY-NC 2.5 license. 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.
