These data include information on the reproductive biology and ecology of Ceraesignum (formerly Dendropoma) maximum.
Related Datasets:
Individual Dendropoma (now Ceraesignum) maximum were collected haphazardly from seven sites in April and September 2008. Snails were removed with their shells intact using a chisel and hammer. In the lab the diameter of the opening of the shell was measured in samples from April. Snails were removed from the shell, and sex, length and wet mass were determined. Sex was determined by the presence of a mantle slit and appearance of gonads in females. Incidence of brooding was recorded for females based on presence of egg capsules.

Description from NSF abstract:
Ecological surprises are most likely to be manifest in diverse communities where many interactions remain uninvestigated. Coral reefs harbor much of the world's biodiversity, and recent studies by the investigators suggest that one overlooked, but potentially important, biological interaction involves vermetid gastropods. Vermetid gastropods are nonmobile, tube-building snails that feed via an extensive mucus net. Vermetids reduce coral growth by up to 80%, and coral survival by as much as 60%. Because effects vary among coral taxa, vermetids may substantially alter the structure of coral communities as well as the community of fishes and invertebrates that inhabit the coral reef.
The investigators will conduct a suite of experimental and observational studies that: 1) quantify the effects of four species of vermetids across coral species to assess if species effects and responses are concordant or idiosyncratic; 2) use meta-analysis to compare effects of vermetids relative to other coral stressors and determine the factors that influence variation in coral responses; 3) determine the role of coral commensals that inhabit the branching coral, Pocillopora, and evaluate how the development of the commensal assemblage modifies the deleterious effects of vermetids; 4) determine how vermetid mucus nets affect the local environment of corals and evaluate several hypotheses about proposed mechanisms; and 5) assess the long-term implications of vermetids on coral communities and the fishes and invertebrates that depend on the coral.
