- -p error cree eee different prey resources by the different Conus species present. Between-species dissimilarity in resource use thus agrees with previous observations on more diverse Conus assemblages of subtidal coral reef platforms. Prey species diversity is inversely related to body size, confirming and extending a previously identified pattern among Conus species that prey on sedentary polychaetes.; Major Descriptors: *MOLLUSCS -- BEHAVIOR; *MOLLUSCS -- POPULATION DYNAMICS Descriptors: AQUATIC ECOSYSTEMS; ENIWETOK; FOOD CHAINS; HABITAT; POPULATION DENSITY; PREDATOR-~PREY INTERACTIONS; SPECIES DIVERSITY Broader Terms: ANIMALS; AQUATIC ORGANISMS; ECOSYSTEMS; INVERTEBRATES; ISLANDS; MARSHALL ISLANDS; MICRONESIA; OCEANIA Subject Categories: 10/5/781 550100* (Item 481 -- Behavioral Biology from file: 103) 00797870 ERA-06-031224; INS-81-015380; EDB-81-106136 Author(s): Colin, P.L.; Harrison, J.T.

Biological and physical-chemical processes of the lagoon floor are relevant to radionuclide mobilization and redistribution. Because of the paucity of general information about the deep lagoon, initial studies were designed to assess benthic community distribution and structure. Two-hundred stations throughout the lagoon are being surveyed using a camera system designed and built at MPRL. These studies of benthic community distribution are augmented by a concurrent research effort to quantify benthic primary production, community metabolism, and cycling of nutrients between the sediments and the overlying water column. Net daily oxygen and nutrient flow data are tabulated. Facilities are described, community relations are discussed, and a plan for future research is given.; Major Descriptors: *BENTHOS -- DISTRIBUTION; *ENIWETOK -- AQUATIC ECOSYSTEMS Descriptors: IMAGES; METABOLISM; NUTRIENTS; OXYGEN; RADIONUCLIDE MIGRATION; RESEARCH PROGRAMS; SURFACE WATERS Broader Terms: AQUATIC ORGANISMS; ECOSYSTEMS; ELEMENTS; ENVIRONMENTAL TRANSPORT; ISLANDS; MARSHALL ISLANDS; MASS TRANSFER; MICRONESIA; NONMETALS; OCEANIA Subject Categories: Studies 520301 -- -- Environment, Aquatic -- Site Resource & Use -- Water -- (1987) -- Environment, Aquatic -- Radioactive Materials Monitoring & Transport -- Aquatic Ecosystems & Food Chains -- INIS Subject Categories: Nuclear Installations 10/5/782 00797714 Title: : -- Environment, Aquatic ~- Radioactive Materials Monitoring & Transport 520302 520500* (-1989) C52* mm Lo -- Radiation Hazards & Safety Evaluations of- (Item 482 from file: 103) INS-81-015361; EDB-81-105980 Paradise lost (-1987) cn cD —) wr
