THE TRANSFORMATION OF BRACHIONUS PALA INTO BRACHIONUS AMPHICEROS BY SODIUM SILICATE [PDF]

open access: yesThe Biological Bulletin, 1916
1. Socium silicate added to the culture medium in which the rotifer Brachionus pala was living caused nearly all and in many cases caused all of the descendants to form two additional posterior lateral spines and also to increase the size of the other spines thus forming Brachionus amphiceros.2.

Nanoplastic Ingestion Enhances Toxicity of Persistent Organic Pollutants (POPs) in the Monogonont Rotifer Brachionus koreanus via Multixenobiotic Resistance (MXR) Disruption.

open access: yesEnvironmental Science and Technology, 2018
Among the various materials found inside microplastic pollution, nanosized microplastics are of particular concern due to difficulties in quantification and detection; moreover, they are predicted to be abundant in aquatic environments with stronger ...

The effect of seasonality on the structure of rotifers in a black-water shallow lake in Central Amazonia

open access: yesAnais da Academia Brasileira de Ciências, 2014
Rotifers have often been used as indicators of sudden changes in physical and chemical features of the aquatic environment. Such features vary greatly during flood pulse events in small lakes connected to major floodplains.

Rotiferan Hox genes give new insights into the evolution of metazoan bodyplans [PDF]

open access: yes, 2017
The phylum Rotifera consists of minuscule, nonsegmented animals with a unique body plan and an unresolved phylogenetic position. The presence of pharyngeal articulated jaws supports an inclusion in Gnathifera nested in the Spiralia.

TOXICITY OF PREDNISOLONE, DEXAMETHASONE AND THEIR PHOTOCHEMICAL DERIVATIVES ON AQUATIC ORGANISMS [PDF]

open access: yes, 2004
Light exposure of aqueous suspensions of prednisolone and dexamethasone causes their partial phototransformation. The photoproducts, isolated by chromatographic techniques, have been identified by spectroscopic means.

Effects of Brachionus calyciflorus and Brachionus rubens on a manipulated freshwater microbial community [PDF]

open access: yesJournal of Plankton Research, 2002
In situ grazing experiments were conducted in a highly eutrophic lake during May and June 1998 to examine species-specific predatory effects of the closely related rotifers Brachionus calyciflorus and Brachionus rubens on the microbial community (

Deepor Beel revisited: new records of rotifers (Rotifera: Eurotatoria) with remarks on interesting species

open access: yesJournal of Threatened Taxa, 2011
Plankton samples collected (April 2009 - March 2010) from Deepor Beel, a Ramsar site, revealed 21 species of the Phylum Rotifera belonging to 12 genera and eight families as new records.

Brachionus rotifers as a model for investigating dietary and metabolic regulators of aging

open access: yesNutrition and Healthy Aging, 2020
Because every species has unique attributes relevant to understanding specific aspects of aging, using a diversity of study systems and a comparative biology approach for aging research has the potential to lead to novel discoveries applicable to human ...

Combined effects of microplastics and temperature on the competition between Brachionus havanaensis and Brachionus calyciflorus (Rotifera)

open access: yesHydrobiologia, 2023
AbstractAquatic organisms are constantly exposed to effluents which often contain microplastics. Microplastics adversely affect aquatic organisms as a result of mechanical damage during ingestion or intoxication by chemicals adsorbed on the microplastics.
