Here we show the use of the 210Pb-226Ra excess method to determine the growth rate of two corals from the world’s largest known cold-water coral reef, Røst Reef, north of the Arctic circle off Norway. Colonies of each of the two species that build the reef, Lophelia pertusa and Madrepora oculata, were collected alive at 350 m depth using a submersible. Pb and Ra isotopes were measured along the...

The marine sponge Haliclona fulva (previously described as Reniera fulva) is widespread in the Mediterranean Sea. The chemical study of the sponge led to the isolation and identification of a new compound: 3-epi-cladocroic acid (1) alongside the previously reported cladocroic acid (2) and some other known compounds previously isolated. The structure was fully determined on the basis of extensiv...

Species of Tethionea Pascoe, 1869, Callidiopini, in the collection Museum Zoologicum Bogoriense are reviewed. Two new species genus described, T. peggieae sp. nov. and oculata nov., both from Papua Province, Indonesia. In addition, unicolor strumosa Pascoe tridentata redescribed. Their male genitalia documented illustrated detail. particular, ejaculatory duct complexes endophalli carefully obse...

In order to characterize the zooplankton community at the Vitória Bay estuarine system (Southeastern Brazil), samples were collected in 10 sampling stations during a three-year study (1998-2000), every three months. A total of 64 taxa were identified. Copepoda contributed with the highest species number (49) in the community, especially with Acartia lilljeborgi, Acartia tonsa, Paracalanus parvu...

Nannochloropsis oculata is a unicellular microalgae which vastly found throughout the environment and have been widely studied due to its high productivity of secondary metabolites oil content. It majorly cultured in aquaculture sector as fish feed for industries polyunsaturated fatty acids. This work aims study impact salinity oxidative stress on expression carotenoid biosynthesis genes accumu...
