Stable carbon isotopic composition of Mytilus edulis shells: relation to metabolism, salinity, δ13CDIC and phytoplankton
Bivalve shells can potentially record the carbon isotopic signature of dissolved inorganic carbon (d 13 CDIC) in estuarine waters, thereby providing information about past estuarine biogeochemicalExpand
Phenotypic study of bacteria associated with the caribbean sclerosponge, Ceratoporella nicholsoni.
Heterotrophic bacteria associated with the Caribbean sclerosponge, Ceratoporella nicholsoni (Hickson), were found to occur extracellularly and were confined to the mesohyl regions of the spongeExpand
Micromorphology and ultrastructure of Caribbean sclerosponges
Fine structural analysis of living tissue of the sclerosponges Ceratoporella nicholsoni (Hickson) and Stromatospongia norae Hartman, collected near Discovery Bay, Jamaica, between 1984 and 1986, wasExpand
Temperature, salinity and growth rate dependences of Mg/Ca and Sr/Ca ratios of the skeleton of the sea urchin Paracentrotus lividus (Lamarck): an experimental approach
The skeletal Mg/Ca ratio of echinoderms is known to increase with temperature but the relation has never been established in controlled experimental conditions. The present study investigated theExpand
Five new species of Homoscleromorpha (Porifera) from the Caribbean Sea and re-description of Plakina jamaicensis
Five new species of Homoscleromorpha (Porifera) of four genera, Oscarella, Plakortis, Plakina and Corticium, are described from vertical walls of reef caves at depths ranging from 23 to 28 m in theExpand
Salinity change in the subtropical Atlantic: Secular increase and teleconnections to the North Atlantic Oscillation
[1] Recent studies comparing shipboard data between the 1950's and the 1990's have shown significant, heterogeneous adjustments of the temperature-salinity structure of the N. Atlantic Ocean. Here,Expand
Sclerosponges as a new potential recorder of environmental changes: Lead in Ceratoporella nicholsoni
Lead concentrations have been analyzed on a 223 yr profile through the aragonitic skeleton of the reef-building Caribbean sclerosponge Ceratoporella nicholsoni by using laser-ablation inductivelyExpand
High-resolution Sr/Ca records in sclerosponges calibrated to temperature in situ
Ratios of strontium to calcium have been analyzed by laser- ablation inductively coupled plasma-mass spectrometry (LA-ICP- MS) in a skeletal section of the sclerosponge Ceratoporella nichol- soni.Expand
Integrative taxonomy of calcareous sponges (subclass Calcinea) from the Peruvian coast: Morphology, molecules, and biogeography
Understanding of evolution and systematics of Calcarea (Porifera) have not yet met a corresponding increase in the knowledge of diversity and distribution of these sponges in several parts of theExpand
Identification of the bacterial symbiont Entotheonella sp. in the mesohyl of the marine sponge Discodermia sp.
The lithistid sponge Discodermia dissoluta (family Theonellidae), is found in deep-waters throughout the Caribbean sea and is the source of discodermolide, a natural product with potential anticancerExpand
