Effects of trace elements on benthic macroinvertebrate distribution in the sediments of two rivers in the Olifants River Basin, South Africa

Journal of Freshwater Ecology, 2023
Many freshwater ecosystems are facing ecological challenges such as influx of trace elements from human activities, and sediments behave as a sink for trace elements in these environments.

Perils of life on the edge: Climatic threats to global diversity patterns of wetland macroinvertebrates.

Science of the Total Environment, 2022
Climate change is rapidly driving global biodiversity declines. How wetland macroinvertebrate assemblages are responding is unclear, a concern given their vital function in these ecosystems.

Preliminary indoor evidences of microplastic effects on freshwater benthic macroinvertebrates

Scientific Reports, 2021
Plastics are to date considered one of the main detrimental drivers for the health of aquatic ecosystems, both in marine and inland waters. Regarding the latter habitat, it seems surprising how the plastic effects on benthic invertebrates are neglected ...

Common carp (Cyprinus carpio L.) alters its feeding niche in response to changing food resources: direct observations in simulated ponds [PDF]

, 2010
We used customized fish tanks as model fish ponds to observe grazing, swimming, and conspecific social behavior of common carp (Cyprinus carpio) under variable food-resource conditions to assess alterations in feeding niche.

Evidence on Night Movements of Macroinvertebrates to Macrophytes in a Pampean Stream [PDF]

, 2014
Nocturnal invertebrate abundance peaks in lotic systems are usually associated to drift, however, diel migrations other than drift may be important in slow-flowing systems.

Assessment of aquatic ecological health based on determination of biological community variability of fish and macroinvertebrates in the Weihe River Basin, China.

Journal of Environmental Management, 2020
A healthy aquatic ecosystem plays an important role in the operation of nature and the survival of human beings. Understanding the mechanism of its interaction with the habitat process is conducive to formulating targeted ecological recovery plans.

Diet of benthivorous fish and prey availability in streams of the Pirapó River basin-PR

Acta Limnologica Brasiliensia, 2019
Aim This study aimed to investigate the diet of seven species of fish that consume predominantly benthic macroinvertebrates, and the availability of these organisms in the environment. We analyzed the occurrence of trophic segregation between species and

What explains the variation in dam impacts on riverine macroinvertebrates? A global quantitative synthesis

Environmental Research Letters, 2020
Dams have fragmented rivers and threatened aquatic biodiversity globally. However, the findings regarding dam impacts on riverine macroinvertebrates vary across regions and taxa.
