Extremely high abundances of Prasiola crispa-associated micrometazoans in East Antarctica

open access: yesPolar Research, 2022
To elucidate poorly known aspects of the microscopic metazoan distribution in ice-free parts of the Antarctic, we examined samples of the multicellular terrestrial alga Prasiola crispa, collected over the last decade in different parts of continental ...

Planktonic rotifers of a saline-lowland river : The Salado River (Argentina) [PDF]

open access: yes, 2002
Seasonal samples of zooplankton were taken during 1997-1999 at fifteen stations in the Salado River basin, and analysed in order to study the rotifer fauna. Spatio-temporal changes in the rotifer plankton composition were examined in the main channel and

Rotifers: Exquisite Metazoans [PDF]

open access: yesIntegrative and Comparative Biology, 2002
Rotifers comprise a modestly sized phylum (≈1,850 species) of tiny (ca. 50-2,000 μm), bilaterally symmetrical, eutelic metazoans, traditionally grouped within the pseudocoelomates or Aschelminthes. These saccate to cylindrically shaped protostomes possess three prominent regions (corona, trunk, foot).

Bdelloid rotifers revisited [PDF]

open access: yesProceedings of the National Academy of Sciences, 2004
Sexual reproduction is one of the most striking features of the biological world. The great majority of the animals and plants with which we are most familiar reproduce at least part of the time by means of sexual reproduction with meiosis, recombination, and fertilization.

A Checklist of Turkish Rotifers

open access: yesTurkish Journal of Zoology, 2012
In a book chapter containing the first checklist and distribution of Turkish rotifers, published in 1999, were listed 167 taxa. The second checklist, published in 2004, reported 229 rotifer taxa in Turkey. During the 7 years since this checklist process, many studies have been carried out and we have prepared a new checklist of Turkish rotifers in the ...

L-carnitine can promote the growth performance of rotifers (Brachionus rotundiformis) by improving their feeding behavior and nutrient composition

open access: yesAquaculture Reports
Rotifer are important food resources in aquaculture hatcheries, and several studies have shown that L-carnitine (LC) can promote the growth performance of rotifers.

An ecological study of Rotifera of the Southern Shatt Al-Arab River, Basrah, Iraq

open access: yesالمجلة العراقية للاستزراع المائي, 2022
At three stations of the Shatt Al-Arab River, the ecology of Rotifera was studied: the first Al-Ashar second Abul Khasib and the third Al-Fao. Seasonal horizontal hauls were taken by a plankton net of a mesh-size of 53-µm during 2013. Density of Rotifera

The Impact of Two Different Cold-Extruded Feeds and Feeding Regimens on Zebrafish Survival, Growth and Reproductive Performance

open access: yesJournal of Developmental Biology, 2018
Zebrafish (Danio rerio) is one of the top model organisms used in biomedical research. Therefore, it is fundamental that zebrafish facilities continuously improve husbandry methods to provide fish with the best physiological and welfare conditions that ...
