 Issued from : E.A. Ershova & K.N. Kosobokova in Biol. Bull., 2012, 39 (8). [p.681, Fig.5]. Schematic structure of the female genital segment of M. longa from White Sea (ventral view): a, with left-sided insemination; b, with right-sided insemination; c, with bilateral insemination. cp: copulatory pore; sp: spermatheca; cd: copulatory duct; g, gonopore. Nota: The authors emphasizes that the vast majority of the females in the studied population in all seasons of the year had only one filled sepermatheca, either the right or the left. The females with bilateral insemination also occurred, but did not exceed 2.7%. The ratio of females with the right and left filled spermathecae and ‘’right-handed’’ and left-handed’’ males suggests thart the male morphotype determines in which spermathecae male gonads are most likely to get into. The presence of females with two filled spermathecae implicates insemination by two males of different morphotypes. Since each spermatheca is connected to only one of the two oviducts, it is assumed that a half of the eggs produced by unilateral inseminated females remains not fertilized. The morphology of genital structures and litterature data on the egg production of M. longa indicate that almost a half of eggs produced by females is not viable and thus wasted.

Fig.3: Biomass share (% of total mesozooplankton dry mass) of Calanus finmarchicus, C. glacialis, C. hyperboreus, Metridia longa and other taxa in 0- to 500 m depth of different Arctic regions (DM total: mean total dry mass).
Note M. longa is a very important calanoid, with regard to both abundance and biomass. its abundance in the upper 500 m ranged generally around 1,200 ind. by m2 at the oceanic stations in the central Arctic Ocean. However, more than 8,000 ind by m2 occurred near the shelf break north of Spitsbergen. |

Nota: Balsfjorden is a semi-enclosed fjord bounded by shallow sills (10-20 m; the species was sampled near Svartnes where the depth is ± 190 m, temperature range from 1-4 °C during most of the year, and light conditions vary from two months of midnight sun and two months of winter darkness. |

Dots are mid-points of sampling intervals. Numbers on top are stations. Hatched area = bottom topography.

Phylogenetic relationships among three Metridia species based on sequence data for a 387 base pair region of the mitochondrial 16S rRNA gene and determined by neighbor joining (Saitou & Nei, 1987). Statistical methods for phylogenetic reconstruction are identical to those for calanus spp..
Numbers on horizontal branches are branch lengths; numbers at branchpoints (in iralics) are percentages of trees that show that branchpoint among 1000 bootstrapped replicates.
Nannocalanus is a outgroup by comparison.

Numbers and dry weight biomass for the total water column (frpm Barrow Strait), before, during, and after the dark period 1984-1985 and 1985-1986 (Conover, Sifred and Harris, unpubl.).
Compare with Calanus hyperboreus, C. glacialis and Pseudocalanus acuspes in the same area of Barrow Strait.
For the authors, the life cycle is understood least well of the several dominant copepods at Resolute (Barrow Strait). While females show little gonad development until May or June, they are common in the population at any season/. Moreover, there is clear evidence for growth and development during the winter. Perhaps a portion of the population can complete a generation in one year.
In laboratory experiments, late-stage readily ingested the large, wax-ester-containing eggs of Calanus hyperboreus, which are abundant in the water column during late winter and spring (Conover, unpubl.). These would constitute an easily caught, highly nutritions energy source to facilitate dark-season growth in any opportunistics species. |

Metridia longa from Wyville Thomson Ridge (60°03.4' N, 07°03.9' W to 60°08' N, 07°02.9' W) on 24 April 1978: Vertical distribution.
Members of this group (Group 2) includes six calanoids species taken predominantly between 430 and 510 m; that is within the intermediate water between North Atlantic Oceanic water (temperatures between 8.0-8.7°C) and Norwegian Sea Deep water. This group contained alsoEukrohnia hamata and Thysanoessa longicaudata.
The group containedin addition to M. longa, Calanus hyperboreus, Heterorhabdus norvegicus, Pleuromamma robusta, Aetideus armatus, Gaetanus minor. Except of the bathypelagic copepods A. armatus, G. minor which are both cosmopolitan species, the organisms in this group are more commonly associated with arctic or boreal water (Fraser, 1961; jespersen, 1934; Einarsson, 1945); their occurrence as a group in the intermediate water suggests that this may possibly have originated from superficial water formed further to nthe north rather than being a mixture of North Atlantic Oceanic water and Norwegian Sea Deep water.
A computed coefficient of dissimilarity was used in association with a 'group-average' clustering strategy (see Clifford & Stephenson, 1975) to classify the plankton taxa on the basis of their vertical distribution after the indices of similarity and the results arranged diagramatically in the form of a dendogram (Fig.2). Classification was carried out using the Bray-Curtis measure which gives a coefficient of dissimilarity. |
