    Ancient DNA reveals key stages in the formation of central European mitochondrial genetic diversity (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-10-12
    Description: The processes that shaped modern European mitochondrial DNA (mtDNA) variation remain unclear. The initial peopling by Palaeolithic hunter-gatherers ~42,000 years ago and the immigration of Neolithic farmers into Europe ~8000 years ago appear to have played important roles but do not explain present-day mtDNA diversity. We generated mtDNA profiles of 364 individuals from prehistoric cultures in Central Europe to perform a chronological study, spanning the Early Neolithic to the Early Bronze Age (5500 to 1550 calibrated years before the common era). We used this transect through time to identify four marked shifts in genetic composition during the Neolithic period, revealing a key role for Late Neolithic cultures in shaping modern Central European genetic diversity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4039305/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4039305/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brandt, Guido -- Haak, Wolfgang -- Adler, Christina J -- Roth, Christina -- Szecsenyi-Nagy, Anna -- Karimnia, Sarah -- Moller-Rieker, Sabine -- Meller, Harald -- Ganslmeier, Robert -- Friederich, Susanne -- Dresely, Veit -- Nicklisch, Nicole -- Pickrell, Joseph K -- Sirocko, Frank -- Reich, David -- Cooper, Alan -- Alt, Kurt W -- Genographic Consortium -- R01 GM100233/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Oct 11;342(6155):257-61. doi: 10.1126/science.1241844.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Anthropology, Johannes Gutenberg University of Mainz, Mainz, Germany. brandtg@uni-mainz.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24115443" target="_blank"〉PubMed〈/a〉

    Southern Ocean iron enrichment experiment: carbon cycling in high- and low-Si waters (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-04-17
    Description: The availability of iron is known to exert a controlling influence on biological productivity in surface waters over large areas of the ocean and may have been an important factor in the variation of the concentration of atmospheric carbon dioxide over glacial cycles. The effect of iron in the Southern Ocean is particularly important because of its large area and abundant nitrate, yet iron-enhanced growth of phytoplankton may be differentially expressed between waters with high silicic acid in the south and low silicic acid in the north, where diatom growth may be limited by both silicic acid and iron. Two mesoscale experiments, designed to investigate the effects of iron enrichment in regions with high and low concentrations of silicic acid, were performed in the Southern Ocean. These experiments demonstrate iron's pivotal role in controlling carbon uptake and regulating atmospheric partial pressure of carbon dioxide.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coale, Kenneth H -- Johnson, Kenneth S -- Chavez, Francisco P -- Buesseler, Ken O -- Barber, Richard T -- Brzezinski, Mark A -- Cochlan, William P -- Millero, Frank J -- Falkowski, Paul G -- Bauer, James E -- Wanninkhof, Rik H -- Kudela, Raphael M -- Altabet, Mark A -- Hales, Burke E -- Takahashi, Taro -- Landry, Michael R -- Bidigare, Robert R -- Wang, Xiujun -- Chase, Zanna -- Strutton, Pete G -- Friederich, Gernot E -- Gorbunov, Maxim Y -- Lance, Veronica P -- Hilting, Anna K -- Hiscock, Michael R -- Demarest, Mark -- Hiscock, William T -- Sullivan, Kevin F -- Tanner, Sara J -- Gordon, R Mike -- Hunter, Craig N -- Elrod, Virginia A -- Fitzwater, Steve E -- Jones, Janice L -- Tozzi, Sasha -- Koblizek, Michal -- Roberts, Alice E -- Herndon, Julian -- Brewster, Jodi -- Ladizinsky, Nicolas -- Smith, Geoffrey -- Cooper, David -- Timothy, David -- Brown, Susan L -- Selph, Karen E -- Sheridan, Cecelia C -- Twining, Benjamin S -- Johnson, Zackary I -- New York, N.Y. -- Science. 2004 Apr 16;304(5669):408-14.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Moss Landing Marine Laboratories, 8272 Moss Landing Road, Moss Landing, CA 95039-9647, USA. coale@mlml.calstate.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15087542" target="_blank"〉PubMed〈/a〉
