Responses of Rotifer Community to Microhabitat Changes Caused by Summer-Concentrated Rainfall in a Shallow Reservoir, South Korea

Diversity, 2020
Empirical studies suggest that the structural heterogeneity of aquatic ecosystem microhabitat is determined by the diversity and abundance of macrophytes.

Dragonfly taxonomic and functional responses to urbanized streams in southeastern Europe, with management recommendations

Insect Conservation and Diversity, EarlyView.
Urbanization drives turnover in dragonfly species composition, traits, and habitat conservation value. Natural stream sections have a higher conservation value (higher DBI) due to presence of specialists. Properly managed urban streams can support diverse dragonfly assemblages.

Integrating water depth to predict the threshold of collapse and recovery of submerged macrophytes for lakes with large depth gradients

Frontiers in Plant Science
IntroductionThe nutrient threshold of collapse and recovery of submerged macrophytes have been widely reported for shallow lakes. However, understanding the threshold variation for lakes with water depth (Z) gradients remains limited.MethodsIn this study,

Note - Potentiels d’utilisation des macrophytes pour réduire l’impact des industries sur les milieux aquatiques européens [PDF]

, 2014
Les macrophytes sont de plus en plus exploités pour atteindre les bons états chimique et écologique recommandés des masses d’eau européennes. Mais quelles sont les particularités des macrophytes en tant qu’outil de bio-surveillance ? Et quelles nouvelles

Empirical modelling of submersed macrophytes in Yangtze lakes

, 2005
Submersed macrophytes in Yangtze lakes have experienced large-scale declines due to the increasing human activities during past decades. To seek the key factor that affects their growth, monthly investigations of submersed macrophytes were conducted in ...

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

Journal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Adsorption of different types of microplastic particles by macrophytes of Lake Baikal

Acta Biologica Sibirica
Submerged macrophytes are capable of adsorbing microplastic particles on their surface. This can affect the vital activity of plants and associated aquatic communities.
