E l l 0 . Bottom communities 88:3529 Atkinson, M.J., 1987. Alkaline phosphatase activity of coral reef benthos. Coral Reefs, 6(2):59-62. Benthic reef algae with epiphytic bacteria had greater alkaline phosphatase (AP-ase) activity than those without epiphytes. Benthic AP-ase activity in an aquarium reef community was >_1000-fold greater than reported water column activity. The AP-ase activity of reef benthos at organic P saturation was high enough that P uptake from organic compounds could equal inorganic P uptake, suggesting the importance of organic P compounds in P recycling.

The spatial scales of pattern explained by active habitat selection and the emerging role of hydrodynamical processes. Oceanogr. mar. Biol. a. Rev., 25:113-165. The process-oriented larval settlement literature and recent data on bottom boundary-layer flows are reviewed with special attention to the spatial and temporal scales of the processes involved. From this review emerges new hypotheses which are based not on an assumption of either passive deposition or active habitat selection, but on a combination of these two processes, each operating on a different temporal and spatial scale. Passive deposition may occur over large spatial scales (meters to km), with active selection occurring over much smaller scales (cm to m), and active selection may be limited to certain times during development.

Ecology, 68(6): 1592-1605. At Tanguisson Reef, Guam, in 1968~9 a population explosion of A. planci devastated the coral community. Using data from previous studies (1970, 1971, 1974) and my data from 1980-81, I present a long-term analysis of coral community development, focusing on recruitment, survivorship, and settlement patterns in relation to the remnant surviving populations. In 12 years, species richness, cover, and composition reached or exceeded measurements of comparable reefs before the disturbance. The recovery occurred faster than predicted because long-term successional changes were not required, and was accelerated because the structural integrity

of the reef framework was not destroyed. Earth Sci. Board, Univ. of Calif., Santa Cruz, CA 94064, USA. 88:3532 Commito, J.A., 1987. Adult-larval interaction: predictions, mussels and cocoons. Estuar. coast. Shelf Sci., 25(5):599-606. Benthic communities outside and inside a dense population of the mussel Mytilus edulis were sampled at a New England soft-bottom intertidal flat. The hypotheses that recruitment of M. edulis is inhibited by densely packed adults, and that M. edulis has a negative effect on recruitment of other infaunal species, were not supported. Dept. of Biol., Hood Coll., Frederick, MD 21701, USA. 88:3533 Done, T.J., 1987.

This report, the first on eastern Pacific meiofauna, describes the meiofaunal community at Isla del Ca~o, Costa Pica in terms of diversity (highest in the coarse, heterogeneous carbonate-rich sands), relative abundance (Foraminifera ~ Copepoda Nematoda ~ Gastropoda ~ Polychaeta ~ Bivalvia), and vertical and horizontal distribution (highly horizontally aggregated, no vertical variation).
