Effects of Grazing by the Sea Urchin, Centrostephanus Coronatus, on Prey Community Composition

Ecology, 1979
Individuals of Centrostephanus coronatus, a diadematid sea urchin, restrict their grazing to relatively confined areas on subtidal rock surfaces. To determine the effects of Centrostephanus grazing on the composition and diversity of the attached biota within these areas, I removed sea urchins from an experimental site and photographically monitored ...

The effect of the predator-avoidance behavior of the sea urchin, Centrostephanus coronatus, on the breadth of its diet

Oecologia, 1979
The sea urchin, Centrostephanus coronatus, exhibits a relatively broad diet. Evidence presented in this paper suggests that evolution of dietary breadth is favored by two mechanisms. First, individual urchins occur in habitat types that support somewhat different foods.

Lunar synchronization of the monthly reproductive rhythm in the sea urchin Centrostephanus coronatus Verrill

Journal of Experimental Marine Biology and Ecology, 1975
Abstract The monthly reproductive rhythm in the diadematid sea urchin Centrostephanus coronatus Verrill at Santa Catalina Island, California, was studied in the summer of 1973 and the results are compared with data for the summer of 1969. In the summer of 1973 the more extreme spring tides coincided with the new moon, while in the summer of 1969 the ...

Diel foraging patterns of the sea urchin Centrostephanus coronatus as a predator avoidance strategy

Marine Biology, 1979
During the day, the diadematid sea urchin Centrostephanus coronatus occupies holes and crevices in shallow subtidal rocky substrata. Individuals emerge from these after sunset and forage on organisms attached to the surrounding rock surface. Each urchin travels

Some effects of turbulence on the activity of the sea urchin Centrostephanus coronatus Verrill

Journal of Experimental Marine Biology and Ecology, 1980
Abstract Effects of turbulence on activity of the sea urchin Centrostephanus coronatus Verrill were studied using a new method referred to as the trip-thread method which recorded incidences of emergence from burrows during activity periods. During calm conditions, the number of C.

A monthly reproductive rhythm in the diadematid sea urchin Centrostephanus coronatus Verill

Journal of Experimental Marine Biology and Ecology, 1972
Abstract A monthly reproductive rhythm, similar to that reported for the sea urchin Diadema setosum (Leske) is described for the diadematid sea urchin Centrosphanus coronatus Verill in southern California. Gametogenesis and spawning in C. coronatus occur with a monthly cycle from about February–March through September.
