This genetic isolation was inferred from the presence of private alleles in some species Cited by:

Finally, this work examines the phylogeography and demographic history of Pseudocalanus minutus, P. moultoni, P. elongatus, P. acuspes and P. newmani in the North Atlantic Ocean and based on these results suggests an evolutionary hypothesis for the divergence of Pseudocalanus spp. into one oceanic and one coastal : Ole Nicolai S Aarbakke.
The pelagic copepod Pseudocalanus elongatus Boeck was bred 3 times from nauplius stages I and II to maturity at 5, 10, 15 and 20*C and at 4 different rations of autotrophic and heterotrophic food. The rate of development of the copepods increased with increasing temperature and food supply. The shortest generation times (from egg to adult) were 59 d at 5*C and 19 d at 15* by: Pseudocalanus species Pseudocalanus elongatus Name Synonyms Calanus clausii Brady, Clausia elongata Boeck, Pseudocalanus minutus elongatus (Boeck, ) Homonyms Pseudocalanus elongatus (Boeck, ) Bibliographic References.

Pseudocalanus. Species: P. elongatus. Binomial name; Pseudocalanus elongatus (Boeck, ) Pseudocalanus elongatus is a copepod found primarily in the Atlantic Ocean. Description. The female P. elongatus ranges from about.7 to millimetres ( to Class: Maxillopoda.

Pseudocalanus minutus (Krøyer) from Halifax have most of their eggs attached to females whereas Pseudocalanus elongatus Boeck from Plymouth only rarely have attached sacs and masses. The outer membrane surrounding the sacs tends to break up forming egg masses and releasing eggs as the time for hatching by: The relative abundance of the six copepodite stages (CI-CVI) of Calanus helgolandicus Claus (Copepoda: Calanoida) and Pseudocalanus elongatus Boeck (Copepoda: Calanoida) was recorded at a station in the English Channel throughout There was a pronounced seasonal variation in the abundance of the early by: Copepods in the genus Pseudocalanus are abundant in temperate-boreal waters of the Northern Hemisphere.
However, their relative distributions are not well known because many species are morphologically cryptic. Here, Pseudocalanus species abundance and distribution in the southeastern Bering Sea from March to June,were determined using samples spanning the middle (50– Cited by: 6.

Author: Thompson, B. ISNI: Awarding Body: University of East Anglia Current Institution: University of East Anglia Date of Award: Availability of Full Text: Access from EThOS. Size, development rate, and fecundity of Pseudocalanus are functions of temperature.
These functions may be difficult to determine and are not general but vary geographically. Egg size is less variable, but a local variant of Pseudocalanus with much larger eggs gives useful clues to the control of size and development rates. The constants of proportionality of size and development rate as Cited by: The Biodiversity Heritage Library works collaboratively to make biodiversity literature openly available to the world as part of a global biodiversity community.
