Brachionus plicatilis Muller 1786

2023
Phylum Rotifera: Brachionus plicatilis SEM Diapausing embryos were ovoid and measured ca 134 µm in diameter (̄x = 134.0 ± 4.0 μm). The outer surface was composed of numerous smooth ridges and wrinkles, creating an overall rough surface (Figure 2a,b). TEM The shell consisted of a thick apical layer and a thin basal layer.

Algal density affects the influences of polyethylene microplastics on the freshwater rotifer Brachionus calyciflorus.

Chemosphere, 2020
Most previous researches focused on the toxicity of polystyrene microplastics (MPs) to marine organisms, but less on polyethylene MPs and freshwater zooplanktons. The present study aims to elucidate the toxicity of polyethylene (PE) MPs (diameter = 10-22

Feeding biology of two brachionid rotifers: Brachionus quadridentatus and Brachionus plicatilis

Hydrobiologia, 1995
Brachionus quadridentatus and Brachionus plicatilis were examined in laboratory cultures to investigate their (1) food requirements and (2) ability to select particles on the basis of size. Growth experiments showed that the Chlorophyceans Nannochloris sp. and Chlorella vulgaris possess good nutritional value for these rotifers.

Progress on the usage of the rotifer Brachionus plicatilis in marine ecotoxicology: A review.

Aquatic Toxicology, 2020
The rotifer, Brachionus plicatilis, is a widely used model species in marine ecotoxicology for evaluating pollutions, toxins, and harmful algae.

Rapid adaptation of Brachionus angularis (Rotifera) to invasion by Brachionus calyciflorus

Hydrobiologia, 2019
To test the hypothesis that Brachionus angularis can rapidly develop local adaptation to invasion by other monogonont rotifers, replicate populations of B. angularis were exposed to two environments invaded by B. calyciflorus at different inoculation densities and an environment free from invaders.

Effects of temperature changes on life parameters, oxidative stress, and antioxidant defense system in the monogonont marine rotifer Brachionus plicatilis.

Marine Pollution Bulletin, 2020
Global warming is a big concern for all organisms and many efforts have been made to reveal the potential effects of temperature elevation on aquatic organisms.

Male discrimination of female Brachionus plicatilis Müller and Brachionus rotundiformis Tschugunoff (Rotifera)

Journal of Experimental Marine Biology and Ecology, 1995
An analysis of mating behavior of three Brachionus plicatilis O.F. Muller and three Brachionus rotundiformis Tschugunoff strains showed that reproductive isolation exists between strains of these sibling species. An atypical B. rotundiformis strain appears to share some characteristics with both B. plicatilis and B. rotundiformis strains.

GABA, 5-HT and amino acids in the rotifers Brachionus plicatilis and Brachionus rotundiformis

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2000
gamma-Aminobutyric acid (GABA) and 5-hydroxytryptamine (5-HT) have been shown to increase the reproduction of the Brachionus plicatilis (NH3L strain). In the present study, the endogenous presence of GABA and 5-HT in the rotifers B. plicatilis (NH3L and Kamiura strains) and Brachionus rotundiformis (Langkawi strain) were confirmed by dot blot ...

Effect of salinity and temperature on the acute and chronic toxicity of arsenic to the marine rotifers Proales similis and Brachionus ibericus.

Marine Pollution Bulletin, 2020
Several abiotic factors influence the ecological responses of aquatic invertebrates to metal toxicity. We examined the effect of salinity (10, 20, and 30 psu) and temperature (25 and 32 °C) on acute and chronic arsenic (As) toxicity to the euryhaline ...

The genome of the marine rotifer Brachionus koreanus sheds light on the antioxidative defense system in response to 2-ethyl-phenanthrene and piperonyl butoxide.

Aquatic Toxicology, 2020
BRACHIONUS: spp. (Rotifera: Monogononta) have been introduced as ecotoxicological model-organisms that are widely distributed in aquatic environments. Among the Brachionus spp., the monogonont rotifer Brachionus koreanus has been widely used for ecology,
