the western U.S. The model predicted (1) total patch area to within 5% of that observed and (2) patch distribution with excellent resolution with respect to time since the last disturbance. The important "connection between disturbance, which generates spatial pattern, and species richness in communities open to invasion is d~ussed.

Both s ~ o w communities (sand and s ~ a s s ) were affected by winter wave stress, although the greater the propo~on of seagrass, the lesser the flux exhibited. Both deep and shailow seagras s commu- nities had greater abundances, species richness and diversity than either of the sand communities. Both sand communities had high community flux rates.

The abundance of detritus at the sediment-water interface (Barnstable Harbor, Massachusetts) yaried seasonally. Diversity of deposit feeders was related to particulate and bulk sedimentary characteristics and to total particulate and food particulate diver' sity. Mar. Res. Lab., P.O.

Species richness, composition, and abundance were considered; the latter two showed significant be- tween-meadow differences, stemming from external events culminating in variable recruitment Success.

Ancestors of the coralline sponge, Ceratoporella nicholsoni, which has a skeleton stronger than that of today's corals, may have built mechanically very resistant Paleozoic/Mesozoic reefs. The evolutionary success of comparatively fragile modern reefbuilders may be due to environmental flexibility resulting from zooxanthellae-enhanced growth and calcifi- cation.
