Distribution map of Acartia (Acanthacartia) steueri by geographical zones
Species Acartia (Acanthacartia) steueri - Distribution map 2issued from : S.-I. Uye in Bull. Plankton Soc. Japan, 1980, 27 (1). [p.14, Fig.4].
Post-embryonic development of Acartia steueri at 13.1, 16.8, 20.3 and 23.0°C, cultered with excess food.

Nota: Isochronal development may be more advantageous than onoisochronal development for some species to ensure high reproductive potential of the population by reducing the mortality during copepodite stages.

Synopsis of feeding/reproduction experiments. A total of 17 diatom and 16 copepod species, representative of a variety of worldwide temperate and subarctic environments (E: estuarine, C: coastal ocean), were screened.
Data for fecundity and hatching success are average values measured at the start and end of the inciubations in a minimum of 3 replicate batches, showing the variation in time of the effects of diatoms on copepod reproduction.
Level of significance of the diatom effect between treatments and controls (e.g. non-diatom diets) in categories I to III was p < 0.01. No.. rank (for comparison with Table 2, p.290).
For the signification of the categories I to IV (fecundity vs. Hatching success vs. Duration of experiment days-1): See Calanus finmarchicus .
List of the 12 marine or estuarine species studied (fresh water excluded. CR): Acartia clausi, A. grani, A. steueri, A. tonsa, Calanus finmarchicus, C. helgolandicus, C. pacificus, Centropages hamatus, C. typicus, Eurytemora affinis, Temora longicornis, T. stylifera.
