Biometry and dissolution features of the benthic foraminifer Ammonia aomoriensis at high pCO2
Culturing experiments were performed with the benthic foraminifer Ammonia aomo riensis from Flensburg Fjord, western Baltic Sea. The experiments simulated a projected rise in atmospheric CO2 concentrations. We exposed specimens to 5 seawater pCO2 levels ranging from 618 μatm (pH 7.9) to 3130 μatm (pH 7.2) for 6 wk. Growth rates and mortality differed significantly among pCO2 treatments. The hig...
متن کاملA new late Eocene Bicornucythere species (Ostracoda, Crustacea) from Myanmar, and its significance for the evolutionary history of the genus.
The ostracode genus Bicornucythere (Ostracoda, Crustacea) is abundant in modern-day eutrophic marine bays, and is widely distributed in estuaries and inner bays throughout East Asia, including in China, Korea, Japan, and the Russian Far East. The evolutionary history of Bicornucythere is poorly understood. Here, we report on a new species of Bicornucythere (Bicornucythere concentrica sp. nov.) ...
متن کاملSpatial distribution and assemblage structure of foraminifera in Nayband Bay and Haleh Estuary, North-West of the Persian Gulf
The spatial distribution of benthic foraminiferal assemblage of Nayband Bay and Haleh Estuary in the North-West of the Persian Gulf, was explored during 2011-2012 . The relationship between spatial pattern of foraminifera assemblages and the ambient factors (i.e. water temperature, salinity, pH, dissolved oxygen, sediment grain size distribution, sediment organic content, and CaCO3 concentrati...
متن کاملA diffusion-reaction model of carbon isotope fractionation in foraminifera
Fossil foraminiferal shells are utilized in paleoceanography to extract information about environmental conditions of the past ocean. Based on several assumptions, the ratio of C and C preserved in their shells is used to reconstruct, for example, the paleoproductivity or the oceanic pCO . Metabolism of the living organism and the sea water chemistry, 2 however, can influence the incorporation ...
متن کاملDistribution, Diversity and Abundance of Benthic Foraminifera of the Northwstern Persian Gulf
During ROPME Winter Cruise 2006, twenty six surface sediment samples taken from the Northwestern part of the Persian Gulf at depths of 13-77m were analyzed for their foraminifera content. A total of 93 species of benthic foraminifera were found in the study area. The foraminifera assemblages were dominated by Ammonia beccarii, Spiroloculina excavata, S. depressa, Quinqueloculina dimidiata,...
