Trophic status of a shallow lake in Inner Mongolia: long-term, seasonal, and spatial variation

open access: yesEcological Indicators, 2023
The study of lake-trophic status drivers and their variable effects over space and time can assist in the management of lake eutrophication. Winter dynamics in lake trophic status are rarely evaluated, yet they could vary drastically from the more ...

Relationship between phytoplankton structure and environmental variables in tropical reservoirs with different trophic states [PDF]

open access: yesActa Botânica Brasílica
Phytoplankton structure is influenced by environmental factors, seasonal cycles and the trophic state of the system. The objective of the present study was to identify guilds of phytoplankton species that are representative of seasonality and trophic ...

Interannual variability in trophic status of shallow lakes on the boreal Plain: Is there a climate signal? [PDF]

open access: yes, 2008
We explored relations between climate and trophic status of shallow lakes (lake area > 5 ha, mean depth < 3.2 m) located on the subhumid western Boreal Plain of Canada. Correlation and regression analyses were used to assess the association between

Understanding patterns and processes in models of trophic cascades [PDF]

open access: yes, 2013
Climate fluctuations and human exploitation are causing global changes in nutrient enrichment of terrestrial and aquatic ecosystems and declining abundances of apex predators. The resulting trophic cascades have had profound effects on food webs, leading

Modelling of Greek Lakes Water Quality Using Earth Observation in the Framework of the Water Framework Directive (WFD)

open access: yesRemote Sensing, 2022
Given the great importance of lakes in Earth’s environment and human life, continuous water quality (WQ) monitoring within the frame of the Water Framework Directive (WFD) is the most crucial aspect for lake management.

Determining trophic niche width: a novel approach using stable isotope analysis [PDF]

open access: yes, 2004
1. Although conceptually robust, it has proven difficult to find practical measures of niche width that are simple to obtain, yet provide an adequate descriptor of the ecological position of the population examined. 2.
