Planktonic indicators of trophic states for a shallow lake (Baiyangdian Lake, China)

Limnologica, 2019
Eutrophication in lake ecosystems poses a serious threat to the water quality and function of aquatic ecosystems. The species composition and community structure of plankton change directly with variations in lake trophic states.

Dynamics of phosphorus composition in suspended particulate matter from a turbid eutrophic shallow lake (Lake Chaohu, China): Implications for phosphorus cycling and management.

Science of the Total Environment, 2020
Particulate phosphorus (P) dominates the total P (TP) content in lacustrine water columns and is a primary source of dissolved P in turbid eutrophic shallow lakes. However, the spatiotemporal variability of P compositions in suspended particulate matter (

Alternative equilibria in shallow lakes

Trends in Ecology & Evolution, 1993
The turbidity of lakes is generally considered to be a smooth function of their nutrient status. However, recent results suggest that over a range of nutrient concentrations, shallow lakes can have two alternative equilibria: a clear state dominated by aquatic vegetation, and a turbid state characterized by high algal biomass.

Spatial variations in diffusive methane fluxes and the role of eutrophication in a subtropical shallow lake.

Science of the Total Environment, 2020
Shallow lakes account for most of the diffusive CH4 emissions from global lakes, and they also suffer from eutrophication worldwide. Determining the effect of eutrophication on diffusive CH4 fluxes is fundamental to understanding CH4 emissions in shallow

The importance of the wind-drag coefficient parameterization for hydrodynamic modeling of a large shallow lake

Ecological Informatics, 2020
Wind strongly impacts the hydrodynamic and biogeochemical process of large shallow lakes, therefore wind stress also plays an important role in modeling the hydrodynamics and water quality of shallow lakes.

Long-term study of ecological restoration in a typical shallow urban lake.

Science of the Total Environment, 2022
We investigated the long-term effects (6 years) of sediment improvement and submerged plant restoration of a subtropical shallow urban lake, Hangzhou West Lake China.

Rapid response of fossil tetraether lipids in lake sediments to seasonal environmental variables in a shallow lake in central China: Implications for the use of tetraether-based proxies

Organic Geochemistry, 2019
Bacterial branched and archaeal isoprenoid glycerol dialkyl glycerol tetraethers (brGDGTs and isoGDGTs, respectively) have become important tools for the paleoclimate reconstruction of lacustrine systems.

Hydrologic and anthropogenic influences on aquatic macrophyte development in a large, shallow lake in China

Freshwater Biology, 2019
Macrophyte composition and abundance affect the overall ecological structure and function of lakes, and information on the nature and timing of changes in macrophyte assemblages is therefore crucial for understanding their impact on the lake ecosystem ...

Wind-induced hydrodynamic changes impact on sediment resuspension for large, shallow Lake Taihu, China

International Journal of Sediment Research, 2019
The internal sediment release is a key factor controlling eutrophication processes in large, shallow lakes. Sediment resuspension is associated with the wave and current induced shear stress in large, shallow lakes.
