Optimal adult growth of Daphnia in a seasonal environment [PDF]

, 1993
1. The cladoceran Daphnia serves as an example of an iteroparous organism, with overlapping generations, that is capable of substantial adult growth. The life history of Daphnia was modelled as the consequence of a series of decisions about allocation of

Comparative metagenomics of Daphnia symbionts [PDF]

, 2009
BACKGROUND: Shotgun sequences of DNA extracts from whole organisms allow a comprehensive assessment of possible symbionts. The current project makes use of four shotgun datasets from three species of the planktonic freshwater crustaceans Daphnia: one ...

Calcium limitation in Daphnia magna [PDF]

Journal of Plankton Research, 2000
The role of ambient calcium concentrations on survival, moulting, growth and egg produc- tion was assessed in the cladoceran Daphnia magna. A threshold for survival was found in the range 0.1-0.5 mg Ca l-1, even when ionic strength of the medium was kept constant. Accumulated length and length specific dry weight was retarded at low Ca (0.5-1.0 mg Ca l-

Identification of General Patterns of Sex-Biased Expression in Daphnia, a Genus with Environmental Sex Determination

G3: Genes, Genomes, Genetics, 2018
Daphnia reproduce by cyclic-parthenogenesis, where phases of asexual reproduction are intermitted by sexual production of diapause stages. This life cycle, together with environmental sex determination, allow the comparison of gene expression between ...

Efekti različitih vrsta organskog đubriva na veličinu tela i produkciju daphnia magna [PDF]

, 2015
U akvakulturi se već decenijama masovno proizvodi zooplankton kao živa hrana za gajenje mlađi riba, rakova i mekušaca. Za slatkovodne ribe se osim naupliusa artemije i rotatorija može koristiti i veliki broj drugih organizama, naročito iz grupe Cladocera

Desiccation of rock pool habitats and its influence onpopulation persistence in a Daphnia metacommunity [PDF]

, 2009
Habitat instability has an important influence on species' occurrence and community composition. For freshwater arthropods that occur in ephemeral rock pools, the most drastic habitat instabilities are droughts and the intermittent availability of water.
