Integrated ecosystem services-based calculation of ecological water demand for a macrophyte-dominated shallow lake

open access: yesGlobal Ecology and Conservation, 2020
Macrophyte-dominated shallow lakes are one of the commonest freshwater wetlands in plain area, and composed of lake, marsh, and terrestrial land. They are, however, facing great ecological risks of serious pollution and wetland degradation caused by the ...

Plant Macrofossils Reveal Aquatic Macrophyte Successions of a Typical Shallow Lake (Huanggai Lake, China) in the Past Century [PDF]

open access: yesPlants, 2022
Aquatic macrophytes are one of the important biotic components of shallow lake ecosystems. Understanding the long-term evolution of the macrophyte community is crucial for lake management.

Bimodality and alternative equilibria do not help explain long-term patterns in shallow lake chlorophyll-a. [PDF]

open access: yesNat Commun, 2023
Shallow lakes have long been considered an example of alternative equilibria in ecological systems. Here, the authors combine empirical data and simulations to show that the relationship of shallow lake chlorophyll-a with nutrient enrichment does not fit

Physiological Toxicity and Antioxidant Mechanism of Photoaging Microplastics on Pisum sativum L. Seedlings

open access: yesToxics, 2023
Recent studies have confirmed that changes in the physical properties of microplastics (MPs) trigger toxicological effects and ecological risks. To explore the toxicity of different types of MPs on plants, and the influence of MP photoaging, this study ...

Effects of Escherichia pollution and salinity on nutrient levels in submerged vegetated wetlands: Insights into benthic community stability and metabolisms

open access: yesWater Science and Technology, 2023
Inner coastal wetland ecosystems are generally eutrophic and are often exposed to both salinity stress and Escherichia coli pollution. However, the effects of these stressors on nutrient-cycling and microbial communities are under-researched.

Effects of Physical Properties and Environmental Conditions on the Natural Dispersion of Oil

open access: yesJournal of Marine Science and Engineering, 2023
The natural dispersion of oil depends on the oil types, wave-mixing energy, and the temperature and salinity of water. Laboratory experiments were conducted to investigate the effects of these factors on oil dispersion.

The Economics of Shallow Lakes [PDF]

open access: yesEnvironmental and Resource Economics, 2000
Ecological systems such as shallow lakes are usually non-linear and display discontinuities and hysteresis in their behaviour. These systems often also provide conflicting services as a resource and a waste sink. This implies that the economic analysis of these systems requires to solve a non-standard optimal control problem or, in case of a common ...

Stimulating effects of submerged plants on removing of N from the water in the Daihai lake of inner Mongolia autonomous region, China

open access: yesFrontiers in Environmental Science, 2023
The Daihai Lake, the third largest lake in Inner Mongolia Autonomous Region, is the cornerstone to maintain the ecosystem balance in this region, which is facing some problems including size shrinking, water quality declining and biodiversity decreasing ...

Spin-related symmetry breaking induced by half-disordered hybridization in BixEr2-xRu2O7 pyrochlores for acidic oxygen evolution

open access: yesNature Communications, 2022
While water electrolysis offers a potential path for renewable hydrogen fuel, water oxidation electrocatalysts typically suffer from poor stabilities in acid.
