Book Description
Gray snappers were collected from four different habitats and examined for trematodes. The incidence of each trematode was calculated for each habitat during each season. Intermediate hosts of the trematodes were also collected. It was found that the habitat in which gray snappers reside is more important than their size, sex, or the season of the year in determining the nature of their trematode populations. This may be the result of the intermediate host distribution being regulated by the habitat. Seasonal changes in trematode populations result from fish movements, such as spawning migrations or movements in response to cold water. The differences between the trematode populations of large and small snappers probably are a function of their residing in different habitats and eating different organisms. The sex of gray snappers has no discernable [i.e. discernible] effect on their trematode populations. Metadena obscura sp. n. (Cryptogonimidae) was found in the pyloric caeca and intestine of Lutjanus griseus (Linnaeus). Nine species of trematodes were found in the intestine and pyloric caeca of Lutjanus griseus near Lower Matecumbe Key: Metadena globosa, M. adglobosa, M. obscura, Paracryptogonimus neoamericanus, Hamacreadium mutabile, H. gulella, Helicometrina nimia, Helicometra execta, and Stephanostomum casum.

Book Description
This book describes the development of ocean sciences over the past 50 years, highlighting the contributions of the National Science Foundation (NSF) to the field's progress. Many of the individuals who participated in the exciting discoveries in biological oceanography, chemical oceanography, physical oceanography, and marine geology and geophysics describe in the book how the discoveries were made possible by combinations of insightful individuals, new technology, and in some cases, serendipity. In addition to describing the advance of ocean science, the book examines the institutional structures and technology that made the advances possible and presents visions of the field's future. This book is the first-ever documentation of the history of NSF's Division of Ocean Sciences, how the structure of the division evolved to its present form, and the individuals who have been responsible for ocean sciences at NSF as "rotators" and career staff over the past 50 years.

Book Description
Ocean science connects a global community of scientists in many disciplines - physics, chemistry, biology, geology and geophysics. New observational and computational technologies are transforming the ability of scientists to study the global ocean with a more integrated and dynamic approach. This enhanced understanding of the ocean is becoming ever more important in an economically and geopolitically connected world, and contributes vital information to policy and decision makers charged with addressing societal interests in the ocean. Science provides the knowledge necessary to realize the benefits and manage the risks of the ocean. Comprehensive understanding of the global ocean is fundamental to forecasting and managing risks from severe storms, adapting to the impacts of climate change, and managing ocean resources. In the United States, the National Science Foundation (NSF) is the primary funder of the basic research which underlies advances in our understanding of the ocean. Sea Change addresses the strategic investments necessary at NSF to ensure a robust ocean scientific enterprise over the next decade. This survey provides guidance from the ocean sciences community on research and facilities priorities for the coming decade and makes recommendations for funding priorities.
