Rondaxe Lake in Herkimer County, New York, represents classic Adirondack Park waters. But over the last quarter-century, Rondaxe – like thousands of lakes in temperate zones around the world – has bee...
Widespread deoxygenation of temperate lakes     lakes  deoxygenation  aquaticsystem       font style='font-size:12px;'> 2021/7/23
The concentration of dissolved oxygen in aquatic systems helps to regulate biodiversity1,2, nutrient biogeochemistry3, greenhouse gas emissions4, and the quality of drinking water5.
Submerged macrophytes are key components of shallow lake biological communities, and their presence has been associated with a predominantly clear-water state.
Cyanobacterial blooms that form in response to climate warming and nutrient enrichment in freshwater lakes have become a global environmental challenge.
Climate changes are predicted to influence gross primary production (GPP) of lakes directly through warming and indirectly through increased loads of allochthonous coloured dissolved organic matter (c...
Phosphorus supply pathways and mechanisms in shallow lakes with different regime     lakes  carbon  nitrogen  (Fe(OOH)~P         font style='font-size:12px;'> 2021/7/27
In order to better understand the pathways and mechanisms of phosphorus (P) supply under different regimes, 12 sampling sites from 4 basins of 2 lakes were studied seasonally from October 2017 to July...
In temperate lakes, it is generally assumed that light rather than temperature constrains phytoplankton growth in winter. Rapid winter warming and increasing observations of winter blooms warrant more...
Winter warming plays a vital role in spring phytoplankton community succession in temperate lakes due to variation of ice cover duration in winter.
Correcting the systematic bias and quantifying uncertainty associated with the operational water quality forecasts are imperative works for risk-based environmental decision making.
