Sea Grant Report Synthesizes Recent Research on LI’s Clams

24.04.2009
Overfishing, brown tide, reduced reproductive success have contributed to the decline of the economically important species, Mercenaria mercenaria

New York Sea Grant (NYSG) announces the release of The Hard Clam Research Initiative: Factors Controlling Mercenaria mercenaria Populations in South Shore Bays of Long Island, NY, a 43-page technical report that summarizes the key results of five research projects funded through NYSG’s Hard Clam Research Initiative which began in 1999.

Funding partners included NOAA National Marine Fisheries Service, South Shore Estuary Reserve, Port Authority of New York and New Jersey, and New York Sea Grant. These five projects and several related studies (all listed below) addressed the downward trend in hard clam populations in Long Island’s south shore bays, an issue of both environmental and economic interest to the region.

Says Ms. Cornelia Schlenk, Assistant Director of New York Sea Grant who spearheaded the Hard Clam Research Initiative, “The main goal in the preparation of this report was to achieve improved, science-based understanding of the factors controlling hard clam populations in Long Island’s south shore estuaries, and thereby contribute towards better management and potential enhancement of a once highly productive regional resource.” Research topics included in the report include: the hard clam’s reduced reproductive success, changes in the clam’s food supply and predators, the effects of brown tide, ecosystem changes in Great South Bay and other LI bays, and the effects of harvesting practices as predicted by clam population models. Continues Ms. Schlenk, “Particular emphasis is given in this synthesis report to findings that have direct implications for the management of hard clam populations.”

Compiled from publications provided by the project investigators, reports submitted to NYSG, and material presented at an August 2008 workshop sponsored by NYSG at the School of Marine and Atmospheric Sciences, Stony Brook University, the report was prepared by V. Monica Bricelj, Ph.D., of the Institute of Marine and Coastal Sciences at Rutgers University.

The entire 43-page report and a separate 7-page excerpt that includes the Executive Summary and the Final Conclusions and Recommendations are available for download (see "Related Info" column in upper right-hand corner of this page). Hard copies are available for free by calling 631-632-9124.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
