Using National Lakes Assessment data, we evaluated the influence of total N (TN), total P (TP), and other variables on lake chlorophyll-a concentrations. With simple linear regressions, high TN/TP samples biased predictions based on TN, and...
Spatial and temporal heterogeneity of methane ebullition in lowland headwater streams and the impact on sampling design [0.03%]
低地山溪甲烷气泡排放时空异质性及其对采样设计的影响
Andrew L Robison,Wilfred M Wollheim,Bonnie Turek et al.
Andrew L Robison et al.
Headwater streams are known sources of methane (CH4) to the atmosphere, but their contribution to global scale budgets remains poorly constrained. While efforts have been made to better understand diffusive fluxes of CH4 in streams, much le...
Decreasing pH impairs sexual reproduction in a Mediterranean coral transplanted at a CO2 vent [0.03%]
降低pH值会损害地中海珊瑚在二氧化碳排放口移植后的有性繁殖能力
Chiara Marchini,Francesca Gizzi,Thomas Pondrelli et al.
Chiara Marchini et al.
Ocean acidification, due to the increase of carbon dioxide (CO2) concentration in the atmosphere and its absorption by the oceans, affects many aspects of marine calcifying organisms' biology, including reproduction. Most of the available s...
Coping with darkness: The adaptive response of marine picocyanobacteria to repeated light energy deprivation [0.03%]
应对黑暗：海洋微微蓝绿菌对反复光照能量剥夺的适应性反应
Allison Coe,Steven J Biller,Elaina Thomas et al.
Allison Coe et al.
The picocyanobacteria Prochlorococcus and Synechococcus are found throughout the ocean's euphotic zone, where the daily light:dark cycle drives their physiology. Periodic deep mixing events can, however, move cells below this region, depriv...
Carbonate fluxes by coccolithophore species between NW Africa and the Caribbean: Implications for the biological carbon pump [0.03%]
西北非洲与加勒比海之间的球石藻种的碳酸盐通量：对生物碳泵的影响
Catarina V Guerreiro,Karl-Heinz Baumann,Geert-Jan A Brummer et al.
Catarina V Guerreiro et al.
Coccolithophores are among the most important calcifying pelagic organisms. To assess how coccolithophore species with different coccolith-carbonate mass and distinct ecological resilience to ocean warming will influence the "rain ratio" an...
Plankton respiration in the Atacama Trench region: Implications for particulate organic carbon flux into the hadal realm [0.03%]
阿塔卡马海沟区域的浮游生物呼吸作用：对颗粒有机碳通量进入哈德深淵的启示
Igor Fernández-Urruzola,Osvaldo Ulloa,Ronnie N Glud et al.
Igor Fernández-Urruzola et al.
Respiration is a key process in the cycling of particulate matter and, therefore, an important control mechanism of carbon export to the ocean's interior. Most of the fixed carbon is lost in the upper ocean, and only a minor amount of organ...
Respiration by "marine snow" at high hydrostatic pressure: Insights from continuous oxygen measurements in a rotating pressure tank [0.03%]
高压下“海洋雪”的呼吸作用——来自旋转压力罐连续氧测量的启示
Peter Stief,Marcus Elvert,Ronnie N Glud
Peter Stief
It is generally anticipated that particulate organic carbon (POC) for most part is degraded by attached microorganisms during the descent of "marine snow" aggregates toward the deep sea. There is, however, increasing evidence that fresh agg...
Coupled dynamics of iron, manganese, and phosphorus in brackish coastal sediments populated by cable bacteria [0.03%]
盐沿海沉积物中铁、锰和磷的耦合动态变化及其与电缆细菌的关系
Martijn Hermans,Marina Astudillo Pascual,Thilo Behrends et al.
Martijn Hermans et al.
Coastal waters worldwide suffer from increased eutrophication and seasonal bottom water hypoxia. Here, we assess the dynamics of iron (Fe), manganese (Mn), and phosphorus (P) in sediments of the eutrophic, brackish Gulf of Finland populated...
Moving ecological and biogeochemical transitions across the North Pacific [0.03%]
跨越北太平洋的生态和生物地球化学转换过程
Christopher L Follett,Stephanie Dutkiewicz,Gael Forget et al.
Christopher L Follett et al.
In the North Pacific Ocean, nutrient rich surface waters flow south from the subpolar gyre through a transitional region and into the subtropics. Along the way, nutrients are used, recycled, and exported, leading to lower biomass and a comm...
Amino acid δ13C and δ15N analyses reveal distinct species-specific patterns of trophic plasticity in a marine symbiosis [0.03%]
氨基酸的碳氮同位素组成揭示了海洋共生体系中不同物种营养级可塑性的特征模式
Christopher B Wall,Natalie J Wallsgrove,Ruth D Gates et al.
Christopher B Wall et al.
Compound-specific isotope analyses (CSIA) and multivariate "isotope fingerprinting" track biosynthetic sources and reveal trophic interactions in food webs. However, CSIA have not been widely applied in the study of marine symbioses. Here, ...
