A study of zooplankton diversity and water quality Lake Dogodogo located in West Burundi was carried out from April to July 2021 six sampling stations, with four selected the littoral zone two remaining pelagic one. The main objective assess using indices for a better management this fishery resource essential surrounding populations. collected twice month between 8 A.M 11 each time. samples we...

Environmental pollution by microplastics has become a severe problem in terrestrial and aquatic ecosystems and, according to actual prognoses, problems will further increase the future. Therefore, assessing quantifying risk for biota is crucial. Standardized short-term toxicological procedures as well methods potential toxic effects over whole life span of an animal are required. We studied eff...

Using rotifer-algal microcosms, we tracked rapid evolution resulting from temporally changing natural selection in ecological predator-prey dynamics. We previously demonstrated that predator-prey oscillations in rotifer-algal laboratory microcosms are qualitatively altered by the presence of genetic variation within the prey. In that study, changes in algal gene frequencies were inferred from t...

Microevolution is typically ignored as a factor directly affecting ongoing population dynamics. We show here that density-dependent natural selection has a direct and measurable effect on a planktonic predator-prey interaction. We kept populations of Brachionus calyciflorus, a monogonont rotifer that exhibits cyclical parthenogenesis, in continuous flow-through cultures (chemostats) for more th...
