Reverse taxonomy applied to the Brachionus calyciflorus cryptic species complex: Morphometric analysis confirms species delimitations revealed by molecular phylogenetic analysis and allows the (re)description of four species. [PDF]

PLoS ONE, 2018
The discovery and exploration of cryptic species have been profoundly expedited thanks to developments in molecular biology and phylogenetics. In this study, we apply a reverse taxonomy approach to the Brachionus calyciflorus species complex, a commonly ...

Temporal Distribution Patterns of Cryptic Brachionus calyciflorus (Rotifera) Species in Relation to Biogeographical Gradient Associated with Latitude. [PDF]

Animals (Basel)
Simple Summary In subtropical shallow lakes, large-scale changes in water temperature lead to seasonal succession of some cryptic rotifer species, and the temporal overlap of other cryptic rotifer species is a common phenomenon.

Differentiation between activity of digestive enzymes of Brachionus calyciflorus and extracellular enzymes of its epizooic bacteria

Journal of Limnology, 2009
The rotifer Brachionus calyciflorus was examined by scanning electron microscopy (SEM) for surface-attached, i.e. epizootic, bacteria to ascertain their specific localization and thus find out if we could discern between rotifer and bacterial enzyme ...

Effects of selected pharmaceuticals (ibuprofen and amoxicillin) on the demography of Brachionus calyciflorus and Brachionus havanaensis (Rotifera)

Egyptian Journal of Aquatic Research, 2016
The levels of emerging chemicals have increased dramatically during the last two decades posing problems for human and environmental health. Pain-killers such as ibuprofen and antibiotics such as amoxicillin are generally consumed together and hence are ...

Niche separation of two cryptic species through temperature‐dependent hatching

Ecosphere
Understanding coexistence between species is a central goal in community ecology. In particular, species of cryptic species complexes that often occur in the same habitats and are morphologically almost identical are interesting subjects for the study of

The Effect of Brachionus calyciflorus (Rotifera) on Larviculture and Fatty Acid Composition of Pikeperch (Sander lucioperca (L.)) Cultured under Pseudo-Green Water Conditions [PDF]

Sustainability, 2022
A new cultivation system with the chlorophyte Monoraphidium contortum combined with a self-sustaining culture of the freshwater rotifer Brachionus calyciflorus was applied for Sander lucioperca (L.) larviculture. Survival, morphometrics, as well as fatty

Suitable Acidified Eggshell Powder Food Promotes Brachionus calyciflorus Growth and Reproduction: From Antioxidant Capacity Insight [PDF]

Aquaculture Nutrition
Rotifers are natural initial bait for fish larvae in freshwater. Here, the effects of various concentrations of acidified eggshell powder solutions (0, 20, 40, 80, 160, and 320 mg/L) on the growth and reproduction of the rotifer Brachionus calyciflorus ...

RAS based culture system for continuous production of Rotifers (Brachionus calyciflorus) in mass

Indian Journal of Animal Sciences, 2020
The present study was undertaken to find out preferred food type, minimum effective algal cell requirement, effective harvest rate of rotifers and to design and construct re-circulatory aquaculture system (RAS) based rotifer, Brachionus calyciflorus ...

Short-term preservation of Brachionus calyciflorus: effects of storage on protein, lipid and carbohydrate contents [PDF]

, 2007
The short-term preservation of Brachionus calyciflorus for 45 days at three different temperatures (4, -4 and -20°C) led to decrease in protein, lipid and carbohydrate contents in all the three cases.
