Subject:
Brachionus; acute toxicity; aquatic organisms; gamma radiation; irradiation; lethal dose 50; no observed adverse effect level
Abstract:
... We examined the tolerance of the monogonont rotifer Brachionus koreanus in response to gamma radiation. In order to determine the median lethal dose (LD50) of rotifers against gamma radiation, we irradiated B. koreanus with gamma rays from 0 to 7000 grays (Gy). The LD50s were 2900 and 2300 Gy at 24 h (LD50-24 h) and 96 h (LD50-96 h) after irradiation, respectively. In addition, the no observed eff ...

Abstract:
... To examine the deleterious effects of the water accommodated fraction (WAF) of crude oil, the growth curve, fecundity, and lifespan of the monogonont rotifer (Brachionus koreanus) were measured for 24 h in response to three different doses (0.2×, 0.4×, and 0.8×) of WAFs. A higher dose of WAFs significantly reduced the fecundity and lifespan. A rotifer 32K microarray chip showed that the Bk-CYP3045 ...

In 10 μg/L TBT-exposed rotifer, the 1 and 0.5 x diet groups resulted in reproduction reduction. However, 10 x diet treatment showed no significant changes in the total fecundity, despite a decrease in daily reproduction. Besides, differences in the lifes ...

Abstract:
... Sex in some cyclically parthenogenetic rotifers is triggered when a threshold population density is achieved. In Brachionus, accumulation of a mixis-inducing protein (MIP) that the rotifers excrete into the medium is the proximal signal. Models explicitly accounting for MIP dynamics suggest that either (1) a positive feedback of MIP concentration on MIP production or (2) a switching relationship b ...

Abstract:
... Triphenyltin (TPT) often coexists with tributyltin (TBT) and Cu in coastal waters worldwide. The combined toxic effect of TPT and TBT has always been assumed to be additive without any scientific proof, and the combined effect of Cu and TPT on marine organisms has not been vigorously studied. This study, therefore, investigated the acute toxicity of binary mixture of TPT/Cu and TPT/TBT to five sel ...

Abstract:
... Many zooplanktonic organisms, like the cyclic parthenogenetic rotifer Brachionus plicatilis (Rotifera: Monogononta), are actually a complex of species and biotypes with a high degree of morphological similarity (i.e. cryptic species). Various phylogenetic studies with molecular markers (e.g. ITS1 and COI) on wild Brachionus populations described the presence of at least nine genetically divergent ...

... As the popularity of marine aquaria grows, the potential exists for increased harvest of marine ornamental fishes and invertebrates from the oceans around the world. Aquaculture may be an alternative source to wild capture fisheries if commercial production protocols can be developed for species of interest, however numerous impediments must be overcome. Experiments were conducted on the reef butt ...

Such variation raises the question whether large genome size differences among individuals might cause reproductive barriers, which could trigger speciation within this group by restricting gene flow across populations. To test this hyp ...

Copepods were the dominant group; rotifers were more abundant than the cladocerans, which were not present in all years. Variation between years in herbivore biomass bore no statistical relationship to patterns in algal biomass. The avera ...

Larvae were analysed 7 and 17 days post fertilization (dpf) to evaluate fatty‐acid profile and morphological variables, respectively. Epinephelus marginatus larvae have relatively slow development of digestive structures, but were able to capture, ingest and di ...

One at a time during the reproductive period of amictic females, oocytes fill with yolk and undergo a mitotic maturation division (oogenesis), are oviposited as single cells, and then develop parthenogenetically into females. Sexual reproduction in Brachionus and several other genera is initiated when amictic females are crowded and oviposit some eggs induced to differentiate into mictic female ...

PURPOSE: Wastes from a former Portuguese steel plant were deposited between 1961 and 2001 on the riverbank of a tributary of the Tagus River creating a landfill connected to the river, posing a potential contamination risk to the Tagus estuary ecosystem. This study aims to assess the transfer of chemical elements from contaminated sediments to the estuarine water from cycles of sediment leaching s ...

To understand the effects of salinity on the monogonont rotifer B. koreanus, we examined high saline (25 and 35psu) conditions compared to the control (15psu). In vivo life cycle parameters (e.g. cumulativ ...

Constructed waters (e.g. dams and retired quarries) are commonly found to have a different zooplankton composition than are natural waters, and to be more readily invaded by non-indigenous species. Constructed ponds are common on farmland, but zooplankton research in these areas is scarce. Consequently, our aims were to (1) compare zooplankton communities between natural ponds and dams in rural en ...

The rotifers Brachionus plicatilis and Brachionus manjavacas are two cryptic species with a considerable ecological overlap in relation to biotic factors. These species often co-occur in temporal brackish ...

Abstract:

In order to study the hatching mechanism, we observed resting eggs and measured their transcriptional expression under different light exposure periods (total darkness, and after 30min, and 4h light). By using differential-display reverse transcription PCR (DDR ...
