pattern occur across benches at a given time and place. ebraeus abundance typically occurs closest to shore; C. C. sponsalis are usually most distant from shore. The peak of C. chaldaeus and However, we found about as many significant within-species differences between censuses made at different times on the same bench as between-species differences within censuses. Co-occurring species thus tend not to use microhabitat resources differentially. Physical environmental variables including tide level, strength of water flow and time of day determine refuging and foraging activity patterns, and all species apear to respond similarly to these factors. The data thus do not support the hypothesis of temporal resource partitioning. We found evidence neither for homing, as mark-recapture results suggested that individuals occupy any convenient refuge after foraging, nor for interference competition for protected sites among Conus. Conus species diversity is Significantly correlated with (1) substrate topographic diversity measured either independently or as the diversity of microhabitats utilized by all species together, and (2) the proportion of individuals occupying protected sites.; Major Descriptors: *MOLLUSCS -- POPULATION DYNAMICS Descriptors: ALGAE; AQUATIC ECOSYSTEMS; BIOLOGICAL FUNCTIONS; BIOLOGICAL STRESS; BIOLOGICAL VARIABILITY; HABITAT; HOME RANGE; PARTITION FUNCTIONS; POPULATION DENSITY; REGIONAL ANALYSIS; SEAWATER; SPECIES DIVERSITY; TIDE; TIME DEPENDENCE; TOLERANCE; WATER CURRENTS Broader Terms: ANIMALS; AQUATIC ORGANISMS; CURRENTS; ECOSYSTEMS; FUNCTIONS; HYDROGEN COMPOUNDS; INVERTEBRATES; OXYGEN COMPOUNDS; PLANTS; WATER Subject Categories: 520100* -- Environment, (-1989) 550100 -- Behavioral Biology 10/5/862 00673283 Aquatic -- Basic Studies -- (Item 562 from file: 103) AIX-11-551901; EDB-80-112810 Title: Effect of plowing on /sup 241/Am contamination in sandy soil Author(s): Crites, T.R.; Denham, D.H.
