Community Production

The mathematical theory of Volterra-Hamilton systems developed for modelling allelopathic interactions in sessile communities, is utilized here to model cost of terpene production of colonizing soft corals and their highly toxic effects on scleractinian corals of the Great Barrier Reef. The central question asked is what strategies of hard corals, if any, would enable them to survive colonization. Several detailed results are obtained relating quantitative measures of terpene production (v), soft coral encroachment (µ), allelopathic vigour (–K) and community production stability. The model predicts that any factor which reduces soft coral encroachment (which includes direct toxic effects) has survival value. Thus, spatial shapes and distributions of scleractinians or refuge in space, in themselves, may constitute viable “cost-effective” competitive defenses. It is unlikely, however, that scleractinian corals could evolve in such a way as to specifically neutralize terpenes directly, according to this model, although their species-specifically variable resistance to their effects can be accounted for.

Disparate Data

AbstractThe discovery of multi-species synchronous spawning of scleractinian corals on the Great Barrier Reef in the 1980s stimulated an extraordinary effort to document spawning times in other parts of the globe. Unfortunately, most of these data remain unpublished which limits our understanding of regional and global reproductive patterns. The Coral Spawning Database (CSD) collates much of these disparate data into a single place. The CSD includes 6178 observations (3085 of which were unpublished) of the time or day of spawning for over 300 scleractinian species in 61 genera from 101 sites in the Indo-Pacific. The goal of the CSD is to provide open access to coral spawning data to accelerate our understanding of coral reproductive biology and to provide a baseline against which to evaluate any future changes in reproductive phenology.

Growth And Reproduction

The distribution, abundance, growth and reproduction of a population of tropical intertidal gastropods, Cerithium moniliferum, at Heron Island, Great Barrier Reef, were examined and related to the incidence of parasitism by 11 digenean trematodes. The snails were patchily distributed on exposed beachrock, and showed little seasonally related change in abundance, but numbers and shell morphs were correlated with sand movements. Snails bred mainly in spring, had a thickened lip to the body whorl at this time and grew mainly from summer through winter, migrating to higher more exposed levels as they grew. There were no seasonal patterns of incidence with any or all trematodes, five of which were moderately common, though rarely did incidence exceed 20% of the population. Parasitism was more common in larger snails with thick lips and eroded shells found at the higher levels of the beachrock. Parasitism presumably steadily increases with age and size, but once infected, snails stop growing. Parasitized snails are castrated and presumably live for about 2-3 years by which time infection rates exceed 50%.
