Ecological Indicators, Год журнала: 2022, Номер 140, С. 109028 - 109028

Cyanobacterial blooms are global threats to freshwater ecosystem functioning, human health, and ecoservices. We assessed impacts of cyanobacterial bloom intensity on plankton functioning using eukaryotic phytoplankton zooplankton indicators associated key physicochemical data collected from four seasons two years at 24 evenly distributed sites in Lake Taihu that has year-around blooms. Our analyses involved comparison site-groups with different intensities analyzing all sampling together comparison, hierarchical partitioning analysis, generalized additive mixed model, structural equation model. found abundance positively TP temperature (negatively TN:TP), while TN. There was an inverse relation trend between relative abundances cyanobacteria, but there no clear absolute cyanobacteria. Rotifers were most dominant when cyanobacteria unabundant, cladocerans presented higher high abundance. Phytoplankton functional richness species negatively intensity. resource use efficiencies (RUEs) rotifers, RUE cladocerans. analytical approach integrating uncovered how shifted altered biological conditions identified the mechanism strength interactive linkages among indicators. Although our results may be oligotrophic lakes or reservoirs, findings provide new insights understanding dynamics communities for polymictic eutrophic lakes, which have broad application enhancing knowledge this subject provides science base managing lake water quality functioning.

Experimental assessment of salinization effects on freshwater zooplankton communities and their trophic interactions under eutrophic conditions

Environmental Pollution, Год журнала: 2022, Номер 313, С. 120127 - 120127

Freshwater ecosystems are becoming saltier due to human activities. The effects of increased salinity can lead cascading trophic interactions, affecting ecosystem functioning and energy transfer, through changes in community size structure. These be modulated by other environmental factors, such as nutrients. For example, communities developed under eutrophic conditions could less sensitive salinization cross-tolerance mechanisms. In this study, we used a mesocosm approach assess the gradient on zooplankton composition structure algal communities. Our results showed that biomass, diversity mean body decreased with chloride concentration induced salt addition. This change did not have phytoplankton. phytoplankton biomass after threshold 500 mg L-1 was reached, most likely direct toxic osmotic regulation nutrient uptake processes certain algae rather than response turnover or top-down control. study help put place mitigation strategies for eutrophication, which often co-occur freshwater ecosystems.

Trait-Based Research on Rotifera: The Holy Grail or Just Messy?

Water, Год журнала: 2023, Номер 15(8), С. 1459 - 1459

Опубликована: Апрель 8, 2023

In recent years, trait-based research on plankton has gained interest because of its potential to uncover general roles in ecology. While trait categories for phytoplankton and crustaceans have been posited, rotifer assessment lagged behind. Here, we reviewed the literature assess traits key their life histories provided a data matrix 138 valid genera phylum Rotifera. We considered seven traits: habitat type, trophi presence lorica foot, predation defense attributes, corona feeding traits. most were morphological attributes supposedly easy assess, faced with several challenges regarding assignment. Feeding especially difficult many relevant information was missing. Our assembled provides foundation that will initiate additional functional diversity, diminish misclassification into categories, facilitate studies across trophic levels.
