Grazing by meso- and microzooplankton on phytoplankton in the upper reaches of the Schelde estuary (Belgium/The Netherlands) [PDF]

, 2005
In contrast with the marine reaches of estuaries, few studies have dealt with zooplankton grazing on phytoplankton in the upper estuarine reaches, where freshwater zooplankton species tend to dominate the zooplankton community. In spring and early summer

Local Adaptation? Enhanced Fitness Under Regional UVB Intensities in a Rock Pool Bdelloid Rotifer

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Bdelloids from the Chihuahuan Desert appear to have adapted to regional UVB intensities in a localized manner. Bdelloids exposed to winter or summer levels of UVB intensity had a longer lifespan and a higher net reproductive rate. ABSTRACT Exposure to ultraviolet radiation (UVR) can decrease lifespan and reduce fecundity in aquatic invertebrates ...

The toxicity comparison of metformin and its degradant guanylurea through multi-routes exposure experiments using algae and rotifer

Ecotoxicology and Environmental Safety
Metformin (MET) and its metabolite guanylurea (GUA) are prevalent in aquatic environments, raising concerns about their potential risks to aquatic organisms. However, the toxicity of these compounds through different exposure routes has not been reported.

Stoichiometric regulation in micro- and mesozooplankton [PDF]

, 2015
Aquatic ecosystems experience large natural variation in elemental composition of carbon (C), nitrogen (N) and phosphorus (P), which is further enhanced by human activities. Primary producers typically reflect the nutrient ratios of their resource, whose

Optimizing Culture Protocols for Cyclops sp.: Innovations in Density, Feed Composition and Dietary Strategies for Freshwater Aquaculture

Aquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT Developing optimized feeding strategies for copepods is essential in contemporary aquaculture, as they serve as a highly nutritious live feed for numerous aquatic organisms. Three experiments were conducted to enhance the development and reproductive success of the copepod, Cyclops sp., to support sustainable aquaculture practices.

Distribution of Brachionus species (Phylum Rotifera) in Cochin backwaters, Kerala, India [PDF]

, 2011
Distribution of thirteen species of Brachionus in nine stations from Cochin backwaters was studied during August 2000-July 2002. Of the 13 species, B. plicatilis and B. rotundiformis were observed in all the stations. B. rotundiformis was dominant with
