Giant clams (Hippopus and Tridacna species) are thought to play various ecological roles in coral reef ecosystems, but most of these have not previously been quantified. Using data from the literature our own studies we elucidate functions giant clams. We show how their tissues food for a wide array predators scavengers, while discharges live zooxanthellae, faeces, gametes eaten by opportunistic feeders. The shells provide substrate colonization epibionts, commensal ectoparasitic organisms...
Abstract The discovery of multi-species synchronous spawning scleractinian corals on the Great Barrier Reef in 1980s stimulated an extraordinary effort to document times other parts globe. Unfortunately, most these data remain unpublished which limits our understanding regional and global reproductive patterns. Coral Spawning Database (CSD) collates much disparate into a single place. CSD includes 6178 observations (3085 were unpublished) time or day for over 300 species 61 genera from 101...
Abstract Efforts to restore coral reefs usually involve transplanting asexually propagated fast-growing corals. However, this approach can lead outplanted populations with low genotypic diversity, composed of taxa susceptible stressors such as marine heatwaves. Sexual propagation leads greater and using slow-growing, stress-tolerant may provide a longer-term return on restoration efforts due higher outplant survival. there have been no reports date detailing the full cycle rearing...
Most studies of coral reproductive biology to date have focused on oocyte numbers and sizes. Only one (ex situ) study has enumerated sperm numbers, even though these data multiple potential applications. We quantified total eggs per gamete bundle collected from six species in situ during a synchronous spawning event Singapore. Egg-sperm bundles were captured midwater as they floated towards the surface after being released by colony. For each sample, semi-transparent soft plastic bottle was...
This paper examines the responses of fluted giant clam Tridacna squamosa pediveligers to elevated temperature and reduced light levels. In a reduction experiment, total 104,000 T. were exposed four different levels shading for approximately one month. The most heavily shaded treatment, at 0.4% ambient light, had significantly lower survival than other groups, which all received 1% or more light. second two weeks 13,000 divided among three treatments: averaging 29.5 °C, with temperatures 32.2...
