Ecological benefits of consistent expression of posterolateral spines in Brachionus calyciflorus

open access: yesJournal of Freshwater Ecology, 2022
Plasticity of spine morphology is a universal phenomenon in rotifers. Some Brachionus calyciflorus clones consistently develop two posterolateral spines (PS) with similar length (Type A), but others (Type B) not. The underlying mechanisms remain unknown.

Influence of spatial trophic patterns on the zooplankton community structure in a tropical urban reservoir in Brazil

open access: yesRevista U.D.C.A Actualidad & Divulgación Científica, 2014
The effect of nutrients inputs, mainly nitrogen and phosphorus on the structure of the zooplankton community, including diversity, evenness, dominance, and richness, in Pampulha Reservoir in the city of Belo Horizonte, Brazil was evaluated.

Eco‐phenotypic feedback loops differ in multistressor environments

open access: yesEcology, Volume 106, Issue 1, January 2025.
Abstract Natural communities are exposed to multiple environmental stressors, which simultaneously impact the population and trait dynamics of the species embedded within these communities. Given that certain traits, such as body size, are known to rapidly respond to environmental change, and given that they can strongly influence the density of ...

Zooplankton in Aquaculture: A Perspective on Nutrition and Cost‐Effectiveness

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Successful aquaculture relies on effective feeding strategies for target species, from the larval stage through to sexually mature adults, in both marine and freshwater environments. Aquatic organisms, particularly larvae, instinctively prefer live feeds like algae and zooplankton; larvae are entirely dependent on live feeds due to their undeveloped ...

Phototransformation of Amlodipine in Aqueous Solution: Toxicity of the Drug and Its Photoproduct on Aquatic Organisms

open access: yesInternational Journal of Photoenergy, 2007
The phototransformation of amlodipine in water was investigated under various conditions. A quantum yield ΦS2.2×10−4 and a half-life time t1/2 0.419 days were calculated when the drug in water (10−4 M) was exposed to sunlight.

Combined effect of concentrations of algal food (Chlorella vulgaris) and salt (sodium chloride) on the population growth of Brachionus calyciflorus and Brachionus patulus (Rotifera)

open access: yesRevista de Biología Tropical, 2003
Salinity is an important variable influencing the density and diversity of rotifers. Studies on salt tolerance of rotifers have so far concentrated on euryhaline species while very little information is available on noneuryhaline taxa.

Interaction between simulated dense Scenedesmus dimorphus (Chlorophyta) bloom and freshwater meta-zooplankton community

open access: yesJournal of Limnology, 2018
Algal bloom has been a subject of much research, especially the occurrence of blue-green algae (cyanobacteria) blooms and their effects on aquatic ecosystems.

Population dynamics of Brachionus calyciflorus (Rotifera: Brachionidae) in waste water from food-processing industry in Mexico

open access: yesRevista de Biología Tropical, 1998
Waste water from Mexico's largest food processing industrial sector (based on maize, nejayote water) was used for growing Brachionus calyciflorus isolated from Lake Chapultepec in the Federal District of Mexico (D.F.).

Effects of enriched Freshwater Rotifer with vitamin C, On Growth indices of Persian sturgeon (Acipenser persicus) larvae rearing.

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2014
Acipenser persicus is the most important sturgeon species in the south Caspian Sea, showing high mortality during larval culture. The aim of this study was to use the freshwater rotifer, Brachionus calyciflorus to feed A.
