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.

Abstract Tragic incidents involving mine tailings spills have impacted many aquatic ecosystems around the world. The massive dam collapse of Fundão, which occurred in Brazil 2015, affected several ecosystems, including shallow and deep lakes lower Doce River basin. Until now, effects on functional diversity zooplankton remain poorly understood. We investigated (functional groups, richness [FRic] evenness [FEve]) lakes, exploring influence environmental variables metals.

Abstract Zooplankton may represent a considerable part of plankton in large rivers, but little is known about the factors that control it. We hypothesized (1) significant longitudinal increase zooplankton abundance, biomass, taxonomic richness, and diversity will occur along free-flowing river section; (2) residence time water more important for population growth than environmental variables such as temperature, oxygen saturation, food concentration; (3) influence tributaries on dynamics insignificant or only has local effect.

Current rates of habitat loss require science-based predictions on how to restore or newly create lost types. In aquatic ecosystems, littoral zones are key habitats for food web functioning, but they often replaced by unnatural steep shorelines water safety. To reverse this trend, knowledge is needed successfully (re)create zones. We quantified the response an large-scale creation new heterogeneous in shallow lake Markermeer, Netherlands. Lake Markermeer was formed dike construction a former estuary, which created heavily modified homogeneous 70,000 ha turbid lacking habitat. Fish and bird populations declined over last decades, classical restoration via return marine conditions would compromise safety large spatial scale prohibited biodiversity offsets. Therefore, innovative "forward-looking restoration" approach adopted: 1000 archipelago called "Marker Wadden" constructed without using historic reference situation to.
