    Description: Kessler et al. (Reports, 21 January 2011, p. 312) reported that methane released from the 2010 Deepwater Horizon blowout, approximately 40% of the total hydrocarbon discharge, was consumed quantitatively by methanotrophic bacteria in Gulf of Mexico deep waters over a 4-month period. We find the evidence explicitly linking observed oxygen anomalies to methane consumption ambiguous and extension of these observations to hydrate-derived methane climate forcing premature.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Joye, Samantha B -- Leifer, Ira -- MacDonald, Ian R -- Chanton, Jeffery P -- Meile, Christof D -- Teske, Andreas P -- Kostka, Joel E -- Chistoserdova, Ludmila -- Coffin, Richard -- Hollander, David -- Kastner, Miriam -- Montoya, Joseph P -- Rehder, Gregor -- Solomon, Evan -- Treude, Tina -- Villareal, Tracy A -- New York, N.Y. -- Science. 2011 May 27;332(6033):1033; author reply 1033. doi: 10.1126/science.1203307.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Marine Sciences, University of Georgia, Athens, GA 30602, USA. mjoye@uga.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21617058" target="_blank"〉PubMed〈/a〉

    Description: Climate change is predicted to increase both drought frequency and duration, and when coupled with substantial warming, will establish a new hydroclimatological model for many regions. Large-scale, warm droughts have recently occurred in North America, Africa, Europe, Amazonia and Australia, resulting in major effects on terrestrial ecosystems, carbon balance and food security. Here we compare the functional response of above-ground net primary production to contrasting hydroclimatic periods in the late twentieth century (1975-1998), and drier, warmer conditions in the early twenty-first century (2000-2009) in the Northern and Southern Hemispheres. We find a common ecosystem water-use efficiency (WUE(e): above-ground net primary production/evapotranspiration) across biomes ranging from grassland to forest that indicates an intrinsic system sensitivity to water availability across rainfall regimes, regardless of hydroclimatic conditions. We found higher WUE(e) in drier years that increased significantly with drought to a maximum WUE(e) across all biomes; and a minimum native state in wetter years that was common across hydroclimatic periods. This indicates biome-scale resilience to the interannual variability associated with the early twenty-first century drought--that is, the capacity to tolerate low, annual precipitation and to respond to subsequent periods of favourable water balance. These findings provide a conceptual model of ecosystem properties at the decadal scale applicable to the widespread altered hydroclimatic conditions that are predicted for later this century. Understanding the hydroclimatic threshold that will break down ecosystem resilience and alter maximum WUE(e) may allow us to predict land-surface consequences as large regions become more arid, starting with water-limited, low-productivity grasslands.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ponce Campos, Guillermo E -- Moran, M Susan -- Huete, Alfredo -- Zhang, Yongguang -- Bresloff, Cynthia -- Huxman, Travis E -- Eamus, Derek -- Bosch, David D -- Buda, Anthony R -- Gunter, Stacey A -- Scalley, Tamara Heartsill -- Kitchen, Stanley G -- McClaran, Mitchel P -- McNab, W Henry -- Montoya, Diane S -- Morgan, Jack A -- Peters, Debra P C -- Sadler, E John -- Seyfried, Mark S -- Starks, Patrick J -- England -- Nature. 2013 Feb 21;494(7437):349-52. doi: 10.1038/nature11836.

    Description: Ecosystem respiration is the biotic conversion of organic carbon to carbon dioxide by all of the organisms in an ecosystem, including both consumers and primary producers. Respiration exhibits an exponential temperature dependence at the subcellular and individual levels, but at the ecosystem level respiration can be modified by many variables including community abundance and biomass, which vary substantially among ecosystems. Despite its importance for predicting the responses of the biosphere to climate change, it is as yet unknown whether the temperature dependence of ecosystem respiration varies systematically between aquatic and terrestrial environments. Here we use the largest database of respiratory measurements yet compiled to show that the sensitivity of ecosystem respiration to seasonal changes in temperature is remarkably similar for diverse environments encompassing lakes, rivers, estuaries, the open ocean and forested and non-forested terrestrial ecosystems, with an average activation energy similar to that of the respiratory complex (approximately 0.65 electronvolts (eV)). By contrast, annual ecosystem respiration shows a substantially greater temperature dependence across aquatic (approximately 0.65 eV) versus terrestrial ecosystems (approximately 0.32 eV) that span broad geographic gradients in temperature. Using a model derived from metabolic theory, these findings can be reconciled by similarities in the biochemical kinetics of metabolism at the subcellular level, and fundamental differences in the importance of other variables besides temperature-such as primary productivity and allochthonous carbon inputs-on the structure of aquatic and terrestrial biota at the community level.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yvon-Durocher, Gabriel -- Caffrey, Jane M -- Cescatti, Alessandro -- Dossena, Matteo -- del Giorgio, Paul -- Gasol, Josep M -- Montoya, Jose M -- Pumpanen, Jukka -- Staehr, Peter A -- Trimmer, Mark -- Woodward, Guy -- Allen, Andrew P -- England -- Nature. 2012 Jul 26;487(7408):472-6. doi: 10.1038/nature11205.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biological & Chemical Sciences, Queen Mary University of London, London E1 4NS, UK. g.yvon-durocher@exeter.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22722862" target="_blank"〉PubMed〈/a〉

    Description: Type I interferons (IFN-alpha and IFN-beta) are important for protection against many viral infections, whereas type II interferon (IFN-gamma) is essential for host defense against some bacterial and parasitic pathogens. Study of IFN responses in human leprosy revealed an inverse correlation between IFN-beta and IFN-gamma gene expression programs. IFN-gamma and its downstream vitamin D-dependent antimicrobial genes were preferentially expressed in self-healing tuberculoid lesions and mediated antimicrobial activity against the pathogen Mycobacterium leprae in vitro. In contrast, IFN-beta and its downstream genes, including interleukin-10 (IL-10), were induced in monocytes by M. leprae in vitro and preferentially expressed in disseminated and progressive lepromatous lesions. The IFN-gamma-induced macrophage vitamin D-dependent antimicrobial peptide response was inhibited by IFN-beta and by IL-10, suggesting that the differential production of IFNs contributes to protection versus pathogenesis in some human bacterial infections.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3653587/" 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/PMC3653587/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Teles, Rosane M B -- Graeber, Thomas G -- Krutzik, Stephan R -- Montoya, Dennis -- Schenk, Mirjam -- Lee, Delphine J -- Komisopoulou, Evangelia -- Kelly-Scumpia, Kindra -- Chun, Rene -- Iyer, Shankar S -- Sarno, Euzenir N -- Rea, Thomas H -- Hewison, Martin -- Adams, John S -- Popper, Stephen J -- Relman, David A -- Stenger, Steffen -- Bloom, Barry R -- Cheng, Genhong -- Modlin, Robert L -- P50 AR063020/AR/NIAMS NIH HHS/ -- R01 AI022553/AI/NIAID NIH HHS/ -- R01 AI047868/AI/NIAID NIH HHS/ -- R01 AI056154/AI/NIAID NIH HHS/ -- R01 AI082575/AI/NIAID NIH HHS/ -- R01 AR040312/AR/NIAMS NIH HHS/ -- R01 AR059126/AR/NIAMS NIH HHS/ -- T32 CA009120/CA/NCI NIH HHS/ -- UL1TR000124/TR/NCATS NIH HHS/ -- New York, N.Y. -- Science. 2013 Mar 22;339(6126):1448-53. doi: 10.1126/science.1233665.

    Description: The vast extent of the Amazon Basin has historically restricted the study of its tree communities to the local and regional scales. Here, we provide empirical data on the commonness, rarity, and richness of lowland tree species across the entire Amazon Basin and Guiana Shield (Amazonia), collected in 1170 tree plots in all major forest types. Extrapolations suggest that Amazonia harbors roughly 16,000 tree species, of which just 227 (1.4%) account for half of all trees. Most of these are habitat specialists and only dominant in one or two regions of the basin. We discuss some implications of the finding that a small group of species--less diverse than the North American tree flora--accounts for half of the world's most diverse tree community.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉ter Steege, Hans -- Pitman, Nigel C A -- Sabatier, Daniel -- Baraloto, Christopher -- Salomao, Rafael P -- Guevara, Juan Ernesto -- Phillips, Oliver L -- Castilho, Carolina V -- Magnusson, William E -- Molino, Jean-Francois -- Monteagudo, Abel -- Nunez Vargas, Percy -- Montero, Juan Carlos -- Feldpausch, Ted R -- Coronado, Euridice N Honorio -- Killeen, Tim J -- Mostacedo, Bonifacio -- Vasquez, Rodolfo -- Assis, Rafael L -- Terborgh, John -- Wittmann, Florian -- Andrade, Ana -- Laurance, William F -- Laurance, Susan G W -- Marimon, Beatriz S -- Marimon, Ben-Hur Jr -- Guimaraes Vieira, Ima Celia -- Amaral, Ieda Leao -- Brienen, Roel -- Castellanos, Hernan -- Cardenas Lopez, Dairon -- Duivenvoorden, Joost F -- Mogollon, Hugo F -- Matos, Francisca Dionizia de Almeida -- Davila, Nallarett -- Garcia-Villacorta, Roosevelt -- Stevenson Diaz, Pablo Roberto -- Costa, Flavia -- Emilio, Thaise -- Levis, Carolina -- Schietti, Juliana -- Souza, Priscila -- Alonso, Alfonso -- Dallmeier, Francisco -- Montoya, Alvaro Javier Duque -- Fernandez Piedade, Maria Teresa -- Araujo-Murakami, Alejandro -- Arroyo, Luzmila -- Gribel, Rogerio -- Fine, Paul V A -- Peres, Carlos A -- Toledo, Marisol -- Aymard C, Gerardo A -- Baker, Tim R -- Ceron, Carlos -- Engel, Julien -- Henkel, Terry W -- Maas, Paul -- Petronelli, Pascal -- Stropp, Juliana -- Zartman, Charles Eugene -- Daly, Doug -- Neill, David -- Silveira, Marcos -- Paredes, Marcos Rios -- Chave, Jerome -- Lima Filho, Diogenes de Andrade -- Jorgensen, Peter Moller -- Fuentes, Alfredo -- Schongart, Jochen -- Cornejo Valverde, Fernando -- Di Fiore, Anthony -- Jimenez, Eliana M -- Penuela Mora, Maria Cristina -- Phillips, Juan Fernando -- Rivas, Gonzalo -- van Andel, Tinde R -- von Hildebrand, Patricio -- Hoffman, Bruce -- Zent, Eglee L -- Malhi, Yadvinder -- Prieto, Adriana -- Rudas, Agustin -- Ruschell, Ademir R -- Silva, Natalino -- Vos, Vincent -- Zent, Stanford -- Oliveira, Alexandre A -- Schutz, Angela Cano -- Gonzales, Therany -- Trindade Nascimento, Marcelo -- Ramirez-Angulo, Hirma -- Sierra, Rodrigo -- Tirado, Milton -- Umana Medina, Maria Natalia -- van der Heijden, Geertje -- Vela, Cesar I A -- Vilanova Torre, Emilio -- Vriesendorp, Corine -- Wang, Ophelia -- Young, Kenneth R -- Baider, Claudia -- Balslev, Henrik -- Ferreira, Cid -- Mesones, Italo -- Torres-Lezama, Armando -- Urrego Giraldo, Ligia Estela -- Zagt, Roderick -- Alexiades, Miguel N -- Hernandez, Lionel -- Huamantupa-Chuquimaco, Isau -- Milliken, William -- Palacios Cuenca, Walter -- Pauletto, Daniela -- Valderrama Sandoval, Elvis -- Valenzuela Gamarra, Luis -- Dexter, Kyle G -- Feeley, Ken -- Lopez-Gonzalez, Gabriela -- Silman, Miles R -- New York, N.Y. -- Science. 2013 Oct 18;342(6156):1243092. doi: 10.1126/science.1243092.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Naturalis Biodiversity Center, Leiden, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24136971" target="_blank"〉PubMed〈/a〉
