Archie Carr, one of the greatest biologists of the twentieth century, played a leading part in finding a new and critical role for natural history and systematics in a post-1950s world dominated by the glamorous science of molecular biology. With the rise of molecular biology came a growing popular awareness of species extinction. Carr championed endangered sea turtles, and his work reflects major shifts in the study of ecology and evolution. A gifted nature writer, his books on the natural history of sea turtles and their habitats in Florida, the Caribbean, and Africa entertained and educated a wide audience. Carr's conservation ethic grew from his field work as well as his friendships with the fishermen who supplied him with many of the stories he retold so engagingly. With Archie Carr as the focus, The Man Who Saved Sea Turtles explores the evolution of the naturalist tradition, biology, and conservation during the twentieth century.
Here Plotkin and her colleagues reveal the nature of these species and the steps needed to make sure they remain a permanent part of the marine environment.
Agriculture in the 21st century will need considerable modification to remain both productive and sustainable. Greater production is needed to meet the needs of our still-growing populations and to combat hunger and poverty. Declines in soil health and the pollution of water sources are making many of our production systems less tenable. These adverse trends are exacerbated more and more by the impacts of climate change. There are, fortunately, alternative methods available for agricultural practice that can countervail these constraints. Biological Approaches to Regenerative Soil Systems brings together the work of both researchers and practitioners to map out better approaches to contempor...
"The commercial landings of threatened and endangered species of marine turtles throughout U.S. waters have never been reported in detail. The early commercial sea turtle landings were sporadically collected and were published in a series of U.S. Government fisheries documents. Unfortunately, they have never been collated and summarized into a single data base or document. These are important base-line fisheries data on U.S. threatened and endangered species of sea turtles and provide considerable insight into the sociology and economics of the turtle fishery. Additionally, these data also provide basic biological information, such as species composition, seasonality, and sizes. These factors are necessary for understanding the ecology of these unique reptiles and enable resource managers to formulate sound management and conservation strategies, as mandated by the Endangered Species Act of 1973, and subsequent amendments. In this report, I summarize the commercial U.S. sea turtle landings as reported by the U.S. Fisheries Commission, Bureau of Commercial Fisheries and National Marine Fisheries Service for the continental U.S., Puerto Rico, and Hawaii"--Introduction
