Aphanomyces daphniae sp.nov., parasitic on Daphnia hyalina
Transactions of the British Mycological Society, 1954Aphanomyces daphnia sp.nov. was found parasitizing Daphnia hyalina var. lacustris. Filamentous zoosporangia emerging through the wall of the host were of typical Aphanomyces type, with a single row of zoospores encysting immediately on emergence. Oogonia were abundant in some specimens, each with a single egg and 1-3 diclinous antheridia.

Daphnia magna can respond to chemical cues from freshly crushed conspecifics with various behavioural reactions. A shift in vertical distribution towards the bottom, the formation of aggregations and direct escape responses can all be induced by water-borne signals released from crushed Daphnia.

Carotenoid pigments are found in the gut wall, fat cells and ovary ofDaphnia. A carotenoid-protein is sometimes present in the blood; the amount varies during an instar. The carotenoid-protein in the eggs ofDaphniaand certain other Cladocera undergoes a change when the embryos are fully developed.

Transcriptional atlas of Daphnia magna
Comparative Biochemistry and Physiology Part D: Genomics and ProteomicsTranscriptomics studies are more likely to achieve predictive results when they rely on tissue- and cell-specific transcriptional data. Identification of cell types in novel model organisms by their transcriptional profiles is difficult without data on transcriptional differences among major tissues and anatomical features.

Functions of haemoglobin inDaphnia
Proceedings of the Royal Society of London. Series B - Biological Sciences, 1950InDaphniaa manifold increase in the haemoglobin content of the blood is known to result from oxygen deficiency in the water; pale animals become red. The functions of this additional haemoglobin have now been studied experimentally. In poorly aerated waterDaphniabenefits from it in the following ways: (1) The additional haemoglobin increases length of ...

The evolutionary ecology of Daphnia
1994In order to generate genetic markers from both nuclear and mitochondrial DNA, we used three PCR-based techniques (RAPD, mtDNA-RFLPs, and sequencing of an amplified mtDNA fragment) to illuminate various aspects of the population genetics of large-lake Daphnia species.

Daphnia models for individual growth and population dynamics have been developed in the manner of models developed by Gurney, McCauley, Andersen and others. All or most of the earlier models were parameterized for Daphnia pulex; we have used the D. pulex model as a baseline model for other species of Daphnia such as magna, galeata and also Bosmina ...
