2023
Phylum Rotifera: Brachionus calyciflorus SEM The ovoid, diapausing embryos measured ca 139 µm in diameter (̄x = 138.4 ± 5.8 μm). Shells appeared largely devoid of ornamentation at lower magnifications (

Feeding in the rotifer Brachionus calyciflorus

Oecologia, 1977
Feeding behavior in B. calyciflorus was observed in both constrained and unconfined individuals. There are at least three mechanisms by which the ingestion of suspended particles may be regulated. First, the cirri of the pseudotrochus may be extended, allowing particles to enter the funnel-shaped buccal field, or they may be bent over medially, forming

Culture of the rotifer Brachionus calyciflorus Pallas

Aquaculture, 1992
Abstract Optimum conditions for raising the rotifer Brachionus calyciflorus Pallas were identified. A temperature of 30 °C and a food concentration of 10 7 cells/ml of the alga Chlorella vulgaris were identified as the most suitable conditions for culture of this rotifer. Maximum production was 81 080 rotifers/1 day −1 . The size and growth rate

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.

Brachionus calyciflorus Pallas (Rotatoria) in Inland Waters of Tropical Latitudes Brachionus calyciflorus Tropical in Waters

Internationale Revue der gesamten Hydrobiologie und Hydrographie, 1995
AbstractThe widely distributed Brachionus calyciflorus was studied for morphological variation based on material from all tropical areas. The subspecies B. calyciflorus borgerti Apstein is redescribed and its subspecific status affirmed. Various forms with local distributions were noted and described and the morphological differences are attributed to ...
