Under-ice environmental conditions, planktonic communities and ichthyofauna in dystrophic lakes

open access: yesThe European Zoological Journal, 2021
High content of humic substances and low pH values are factors limiting the species richness and abundance of some organisms in dystrophic lakes. Unfavourable winter conditions (i.e.

Role of Rotifers in Betanodavirus Transmission to European Sea Bass Larvae

open access: yesFrontiers in Veterinary Science, 2022
Marine invertebrates such as rotifers or Artemia, frequently used for fish larvae feeding, can be a potential source of pathogens. It has been demonstrated that Artemia can act as a nervous necrosis virus (NNV)-vector to Senegalese sole larvae. Therefore,

The effects of zinc-enriched Saccharomyces cerevisiae on the growth and mineral composition of marine rotifer, Brachionus plicatilis

open access: yesInternational Journal of Aquatic Biology, 2018
Rotifers are important zooplankton in commercial finfish hatcheries. However, due to the limited variety of food available, zinc content of cultured rotifers in artificial environments may not meet the requirements of fish larval.

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).

A Preliminary Survey on the Planktonic Biota in a Hypersaline Pond of Messolonghi Saltworks (W. Greece)

open access: yesDiversity, 2021
During a survey in 2015, an impressive assemblage of organisms was found in a hypersaline pond of the Messolonghi saltworks. The salinity ranged between 50 and 180 ppt, and the organisms that were found fell into the categories of Cyanobacteria (17 ...

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 ...

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.
