Studies on the survival of the rotifer philodina after freezing and thawing

Cryobiology, 1967
Summary The survival of the rotifer Philodina after freezing and thawing has been examined under a variety of experimental conditions. Particular emphasis was placed on obtaining maximum survival by employing the most advantageous combination of protective additive concentration and cooling rate.

Assessing the Performance of a Bdelloid Rotifer Philodina acuticornis odiosa Acute Toxicity Assay

Bulletin of Environmental Contamination and Toxicology, 2008
A bioassay using the bdelloid rotifer, Philodina acuticornis odiosa, was evaluated for use as a standard test method for direct toxicity assessment testing in the Australasian region. Philodina acuticornis odiosa was found to be relatively tolerant to phenol (24 h LC50, 142 mg/L).

Fine structure of the female genital apparatus of Philodina (Rotifera, Bdelloidea)

Zoomorphology, 1982
The organization of the female genital apparatus of the bdelloid rotifer Philodina roseola was analyzed by light and electron microscopy. It differs from that of the monogononts in several respects: the gonad is paired; in each gonad, the follicular layer completely surrounds the syncytial vitellarium and the cluster of ovocytes; the cytoplasmic ...

Freshwater toxicity testing using rehydratedPhilodinasp. (Rotifera) as test animals

Environmental Toxicology, 2017
Rotifers have become widely used in aquatic toxicology as a rapid screening test for toxicity. The commercial availability of diapausing embryos (cysts) have facilitated their popularity because test animals can be obtained without having to master the details of culturing.
