Rotifers in Lake Itasca [PDF]

, 1977
Rotifers were collected from both the Littoral and Limnetic zones in Lake Itasca, Clearwater County, Minnesota, during two weeks in midsummer. In total, 82 species of rotifers were found, and 69 were identified to species.

Rotifers in saltwater environments, re-evaluation of an inconspicuous taxon [PDF]

, 2006
Rotifers are microscopic aquatic animals that comprise more than 1800 species. Most rotifer species live in freshwater and limno-terrestrial habitats, while thalassic environments (brackish+seawater) are thought to host few species.

Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

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

Polar 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 ...

Sterols of the rotifer.

NIPPON SUISAN GAKKAISHI, 1979
The sterol components of the rotifer, Brachionus plicatilis, the marine type of Chlorella, Chlorella saccharophila, and the baker's yeast, Saccharomyces cerevisie, were investigated by using combined gas-liquid chromatography and mass spectrometry. The rotifer contained 24-methylcholesta-7, 22-dienol as a major sterol (61% of total sterols), and other ...

Enhanced rates of particulate organic matter remineralization by microzooplankton are diminished by added ballast minerals [PDF]

, 2013
To examine the potentially competing influences of microzooplankton and calcite mineral ballast on organic matter remineralization, we incubated diatoms in darkness in rolling tanks with and without added calcite minerals (coccoliths) and ...

Larval Arctic cod (Boreogadus saida) exhibit stronger developmental and physiological responses to temperature than to elevated pCO2

Journal of Fish Biology, EarlyView.
Abstract High‐latitude ecosystems are simultaneously warming and acidifying under ongoing climate change. Arctic cod (Boreogadus saida) are a key species in the Arctic Ocean and have demonstrated sensitivity to ocean warming and acidification as adults and embryos, but their larval sensitivity to the combined stressors is unknown. In a laboratory multi‐

Observations of linear aggregation behavior in rotifers (Brachionus calyciflorus). [PDF]

, 2021
Linear aggregation is present in some animals, such as the coordinated movement of ants and the migration of caterpillars and spinylobsters, but none has been reported on rotifers.
