Recovery from multi-millennial natural coastal hypoxia in the Stockholm Archipelago, Baltic Sea, terminated by modern human activity [0.03%]
斯德哥尔摩 archipelago 海域多千年自然海岸带低氧状态的恢复因现代人类活动而终止——来自波罗的海的研究

Niels A G M van Helmond et al.
Enhanced nutrient input and warming have led to the development of low oxygen (hypoxia) in coastal waters globally. For many coastal areas, insight into redox conditions prior to human impact is lacking. Here, we reconstructed bottom water ...
Deep chlorophyll maxima across a trophic state gradient: A case study in the Laurentian Great Lakes [0.03%]
叶绿素深最大值在营养状况梯度上的变化——以五大湖区为例研究

Deep chlorophyll maxima (DCM) are common in stratified lakes and oceans, and phytoplankton growth within DCM often contributes significantly to total system production. Theory suggests that properties of DCM should be predictable by trophic...
Spatial variability of sediment methane production and methanogen communities within a eutrophic reservoir: Importance of organic matter source and quantity [0.03%]
沉积物甲烷产生和产甲烷菌群落的空间变异性的研究：有机物质来源和数量的重要性研究

Megan E Berberich et al.
Freshwater reservoirs are an important source of the greenhouse gas methane (CH4) to the atmosphere, but global emission estimates are poorly constrained (13.3-52.5 Tg C yr-1), partially due to extreme spatial variability in emission rates ...
Effects of 10 yr of nitrogen and phosphorus fertilization on carbon and nutrient cycling in a tidal freshwater marsh [0.03%]

Tidal freshwater marshes can protect downstream ecosystems from eutrophication by intercepting excess nutrient loads, but recent studies in salt marshes suggest nutrient loading compromises their structural and functional integrity. Here, w...
Vertically challenged: How disease suppresses Daphnia vertical migration behavior [0.03%]
竖直方向上的挑战：疾病如何抑制水蚤的垂直迁移行为

Parasitic infections are increasingly recognized as influential forces in the migratory behaviors of hosts ranging from butterflies to whales. In aquatic zooplankton, diel vertical migrations (DVMs) are among the most recurrent behaviors wi...
Molecular and biochemical basis for the loss of bioluminescence in the dinoflagellate Noctiluca scintillans along the west coast of the USA [0.03%]
美国西海岸夜光藻（Noctiluca scintillans）生物荧光丧失的分子和生化基础

Martha Valiadi et al.
The globally distributed heterotrophic dinoflagellate Noctiluca scintillans (Macartney) Kofoid & Swezy is well known for its dense blooms and prominent displays of bioluminescence. Intriguingly, along the west coast of the USA its blooms ar...

Mercury (Hg) is a natural and widespread trace metal, but is considered a priority pollutant, particularly its organic form methylmercury (MMHg), because of human's exposure to MMHg through fish consumption. Pioneering studies showed the me...

The empirical relationship between total phosphorus and chlorophyll has guided lake management decisions for decades, but imprecision in this relationship in individual lakes limits the utility of these models. Many environmental factors th...
