    A serpentinite-hosted ecosystem: the Lost City hydrothermal field (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-03-05
    Description: The serpentinite-hosted Lost City hydrothermal field is a remarkable submarine ecosystem in which geological, chemical, and biological processes are intimately interlinked. Reactions between seawater and upper mantle peridotite produce methane- and hydrogen-rich fluids, with temperatures ranging from 〈40 degrees to 90 degrees C at pH 9 to 11, and carbonate chimneys 30 to 60 meters tall. A low diversity of microorganisms related to methane-cycling Archaea thrive in the warm porous interiors of the edifices. Macrofaunal communities show a degree of species diversity at least as high as that of black smoker vent sites along the Mid-Atlantic Ridge, but they lack the high biomasses of chemosynthetic organisms that are typical of volcanically driven systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelley, Deborah S -- Karson, Jeffrey A -- Fruh-Green, Gretchen L -- Yoerger, Dana R -- Shank, Timothy M -- Butterfield, David A -- Hayes, John M -- Schrenk, Matthew O -- Olson, Eric J -- Proskurowski, Giora -- Jakuba, Mike -- Bradley, Al -- Larson, Ben -- Ludwig, Kristin -- Glickson, Deborah -- Buckman, Kate -- Bradley, Alexander S -- Brazelton, William J -- Roe, Kevin -- Elend, Mitch J -- Delacour, Adelie -- Bernasconi, Stefano M -- Lilley, Marvin D -- Baross, John A -- Summons, Roger E -- Sylva, Sean P -- New York, N.Y. -- Science. 2005 Mar 4;307(5714):1428-34.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Oceanography, University of Washington, Seattle, WA 98195, USA. kelley@ocean.washington.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15746419" target="_blank"〉PubMed〈/a〉

    Ecological dynamics across the Arctic associated with recent climate change (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-09-12
    Description: At the close of the Fourth International Polar Year, we take stock of the ecological consequences of recent climate change in the Arctic, focusing on effects at population, community, and ecosystem scales. Despite the buffering effect of landscape heterogeneity, Arctic ecosystems and the trophic relationships that structure them have been severely perturbed. These rapid changes may be a bellwether of changes to come at lower latitudes and have the potential to affect ecosystem services related to natural resources, food production, climate regulation, and cultural integrity. We highlight areas of ecological research that deserve priority as the Arctic continues to warm.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Post, Eric -- Forchhammer, Mads C -- Bret-Harte, M Syndonia -- Callaghan, Terry V -- Christensen, Torben R -- Elberling, Bo -- Fox, Anthony D -- Gilg, Olivier -- Hik, David S -- Hoye, Toke T -- Ims, Rolf A -- Jeppesen, Erik -- Klein, David R -- Madsen, Jesper -- McGuire, A David -- Rysgaard, Soren -- Schindler, Daniel E -- Stirling, Ian -- Tamstorf, Mikkel P -- Tyler, Nicholas J C -- van der Wal, Rene -- Welker, Jeffrey -- Wookey, Philip A -- Schmidt, Niels Martin -- Aastrup, Peter -- New York, N.Y. -- Science. 2009 Sep 11;325(5946):1355-8. doi: 10.1126/science.1173113.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Penn State University, 208 Mueller Lab, University Park, PA 16802, USA. esp10@psu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19745143" target="_blank"〉PubMed〈/a〉

    Coastal ecosystem-based management with nonlinear ecological functions and values (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-01-19
    Description: A common assumption is that ecosystem services respond linearly to changes in habitat size. This assumption leads frequently to an "all or none" choice of either preserving coastal habitats or converting them to human use. However, our survey of wave attenuation data from field studies of mangroves, salt marshes, seagrass beds, nearshore coral reefs, and sand dunes reveals that these relationships are rarely linear. By incorporating nonlinear wave attenuation in estimating coastal protection values of mangroves in Thailand, we show that the optimal land use option may instead be the integration of development and conservation consistent with ecosystem-based management goals. This result suggests that reconciling competing demands on coastal habitats should not always result in stark preservation-versus-conversion choices.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barbier, Edward B -- Koch, Evamaria W -- Silliman, Brian R -- Hacker, Sally D -- Wolanski, Eric -- Primavera, Jurgenne -- Granek, Elise F -- Polasky, Stephen -- Aswani, Shankar -- Cramer, Lori A -- Stoms, David M -- Kennedy, Chris J -- Bael, David -- Kappel, Carrie V -- Perillo, Gerardo M E -- Reed, Denise J -- New York, N.Y. -- Science. 2008 Jan 18;319(5861):321-3. doi: 10.1126/science.1150349.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Economics and Finance, University of Wyoming, Laramie, WY 82071, USA. ebarbier@uwyo.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18202288" target="_blank"〉PubMed〈/a〉

    Drought sensitivity of the Amazon rainforest (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-03-07
    Description: Amazon forests are a key but poorly understood component of the global carbon cycle. If, as anticipated, they dry this century, they might accelerate climate change through carbon losses and changed surface energy balances. We used records from multiple long-term monitoring plots across Amazonia to assess forest responses to the intense 2005 drought, a possible analog of future events. Affected forest lost biomass, reversing a large long-term carbon sink, with the greatest impacts observed where the dry season was unusually intense. Relative to pre-2005 conditions, forest subjected to a 100-millimeter increase in water deficit lost 5.3 megagrams of aboveground biomass of carbon per hectare. The drought had a total biomass carbon impact of 1.2 to 1.6 petagrams (1.2 x 10(15) to 1.6 x 10(15) grams). Amazon forests therefore appear vulnerable to increasing moisture stress, with the potential for large carbon losses to exert feedback on climate change.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Phillips, Oliver L -- Aragao, Luiz E O C -- Lewis, Simon L -- Fisher, Joshua B -- Lloyd, Jon -- Lopez-Gonzalez, Gabriela -- Malhi, Yadvinder -- Monteagudo, Abel -- Peacock, Julie -- Quesada, Carlos A -- van der Heijden, Geertje -- Almeida, Samuel -- Amaral, Ieda -- Arroyo, Luzmila -- Aymard, Gerardo -- Baker, Tim R -- Banki, Olaf -- Blanc, Lilian -- Bonal, Damien -- Brando, Paulo -- Chave, Jerome -- de Oliveira, Atila Cristina Alves -- Cardozo, Nallaret Davila -- Czimczik, Claudia I -- Feldpausch, Ted R -- Freitas, Maria Aparecida -- Gloor, Emanuel -- Higuchi, Niro -- Jimenez, Eliana -- Lloyd, Gareth -- Meir, Patrick -- Mendoza, Casimiro -- Morel, Alexandra -- Neill, David A -- Nepstad, Daniel -- Patino, Sandra -- Penuela, Maria Cristina -- Prieto, Adriana -- Ramirez, Fredy -- Schwarz, Michael -- Silva, Javier -- Silveira, Marcos -- Thomas, Anne Sota -- Steege, Hans Ter -- Stropp, Juliana -- Vasquez, Rodolfo -- Zelazowski, Przemyslaw -- Alvarez Davila, Esteban -- Andelman, Sandy -- Andrade, Ana -- Chao, Kuo-Jung -- Erwin, Terry -- Di Fiore, Anthony -- Honorio C, Euridice -- Keeling, Helen -- Killeen, Tim J -- Laurance, William F -- Pena Cruz, Antonio -- Pitman, Nigel C A -- Nunez Vargas, Percy -- Ramirez-Angulo, Hirma -- Rudas, Agustin -- Salamao, Rafael -- Silva, Natalino -- Terborgh, John -- Torres-Lezama, Armando -- New York, N.Y. -- Science. 2009 Mar 6;323(5919):1344-7. doi: 10.1126/science.1164033.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ecology and Global Change, School of Geography, University of Leeds, Leeds LS2 9JT, UK. o.phillips@leeds.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19265020" target="_blank"〉PubMed〈/a〉

    Eddy/wind interactions stimulate extraordinary mid-ocean plankton blooms (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-05-19
    Description: Episodic eddy-driven upwelling may supply a significant fraction of the nutrients required to sustain primary productivity of the subtropical ocean. New observations in the northwest Atlantic reveal that, although plankton blooms occur in both cyclones and mode-water eddies, the biological responses differ. Mode-water eddies can generate extraordinary diatom biomass and primary production at depth, relative to the time series near Bermuda. These blooms are sustained by eddy/wind interactions, which amplify the eddy-induced upwelling. In contrast, eddy/wind interactions dampen eddy-induced upwelling in cyclones. Carbon export inferred from oxygen anomalies in eddy cores is one to three times as much as annual new production for the region.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGillicuddy, Dennis J Jr -- Anderson, Laurence A -- Bates, Nicholas R -- Bibby, Thomas -- Buesseler, Ken O -- Carlson, Craig A -- Davis, Cabell S -- Ewart, Courtney -- Falkowski, Paul G -- Goldthwait, Sarah A -- Hansell, Dennis A -- Jenkins, William J -- Johnson, Rodney -- Kosnyrev, Valery K -- Ledwell, James R -- Li, Qian P -- Siegel, David A -- Steinberg, Deborah K -- New York, N.Y. -- Science. 2007 May 18;316(5827):1021-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Woods Hole Oceanographic Institution, Woods Hole, MA 02543-1541, USA. dmcgillicuddy@whoi.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17510363" target="_blank"〉PubMed〈/a〉

    One-third of reef-building corals face elevated extinction risk from climate change and local impacts (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-07-26
    Description: The conservation status of 845 zooxanthellate reef-building coral species was assessed by using International Union for Conservation of Nature Red List Criteria. Of the 704 species that could be assigned conservation status, 32.8% are in categories with elevated risk of extinction. Declines in abundance are associated with bleaching and diseases driven by elevated sea surface temperatures, with extinction risk further exacerbated by local-scale anthropogenic disturbances. The proportion of corals threatened with extinction has increased dramatically in recent decades and exceeds that of most terrestrial groups. The Caribbean has the largest proportion of corals in high extinction risk categories, whereas the Coral Triangle (western Pacific) has the highest proportion of species in all categories of elevated extinction risk. Our results emphasize the widespread plight of coral reefs and the urgent need to enact conservation measures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carpenter, Kent E -- Abrar, Muhammad -- Aeby, Greta -- Aronson, Richard B -- Banks, Stuart -- Bruckner, Andrew -- Chiriboga, Angel -- Cortes, Jorge -- Delbeek, J Charles -- Devantier, Lyndon -- Edgar, Graham J -- Edwards, Alasdair J -- Fenner, Douglas -- Guzman, Hector M -- Hoeksema, Bert W -- Hodgson, Gregor -- Johan, Ofri -- Licuanan, Wilfredo Y -- Livingstone, Suzanne R -- Lovell, Edward R -- Moore, Jennifer A -- Obura, David O -- Ochavillo, Domingo -- Polidoro, Beth A -- Precht, William F -- Quibilan, Miledel C -- Reboton, Clarissa -- Richards, Zoe T -- Rogers, Alex D -- Sanciangco, Jonnell -- Sheppard, Anne -- Sheppard, Charles -- Smith, Jennifer -- Stuart, Simon -- Turak, Emre -- Veron, John E N -- Wallace, Carden -- Weil, Ernesto -- Wood, Elizabeth -- New York, N.Y. -- Science. 2008 Jul 25;321(5888):560-3. doi: 10.1126/science.1159196.

    Planktonic foraminifera of the California Current reflect 20th-century warming (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-01-10
    Description: It is currently unclear whether observed pelagic ecosystem responses to ocean warming, such as a mid-1970s change in the eastern North Pacific, depart from typical ocean variability. We report variations in planktonic foraminifera from varved sediments off southern California spanning the past 1400 years. Increasing abundances of tropical/subtropical species throughout the 20th century reflect a warming trend superimposed on decadal-scale fluctuations. Decreasing abundances of temperate/subpolar species in the late 20th century indicate a deep, penetrative warming not observed in previous centuries. These results imply that 20th-century warming, apparently anthropogenic, has already affected lower trophic levels of the California Current.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Field, David B -- Baumgartner, Timothy R -- Charles, Christopher D -- Ferreira-Bartrina, Vicente -- Ohman, Mark D -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):63-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Scripps Institution of Oceanography, University of California, San Diego, La Jolla, CA 92093, USA. dfield@mbari.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16400144" target="_blank"〉PubMed〈/a〉

    Revisiting carbon flux through the ocean's twilight zone (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-04-28
    Description: The oceanic biological pump drives sequestration of carbon dioxide in the deep sea via sinking particles. Rapid biological consumption and remineralization of carbon in the "twilight zone" (depths between the euphotic zone and 1000 meters) reduce the efficiency of sequestration. By using neutrally buoyant sediment traps to sample this chronically understudied realm, we measured a transfer efficiency of sinking particulate organic carbon between 150 and 500 meters of 20 and 50% at two contrasting sites. This large variability in transfer efficiency is poorly represented in biogeochemical models. If applied globally, this is equivalent to a difference in carbon sequestration of more than 3 petagrams of carbon per year.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Buesseler, Ken O -- Lamborg, Carl H -- Boyd, Philip W -- Lam, Phoebe J -- Trull, Thomas W -- Bidigare, Robert R -- Bishop, James K B -- Casciotti, Karen L -- Dehairs, Frank -- Elskens, Marc -- Honda, Makio -- Karl, David M -- Siegel, David A -- Silver, Mary W -- Steinberg, Deborah K -- Valdes, Jim -- Van Mooy, Benjamin -- Wilson, Stephanie -- New York, N.Y. -- Science. 2007 Apr 27;316(5824):567-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Marine Chemistry and Geochemistry, Woods Hole Oceanographic Institution, Woods Hole, MA 02543, USA. kbuesseler@whoi.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17463282" target="_blank"〉PubMed〈/a〉
