Mesozooplankton assemblages in the shallow Arctic Laptev Sea in summer 1993 and autumn 1995

Limnocalanus macrurus in the Kara Sea (Arctic Ocean): an opportunistic copepod as evident from distribution and lipid patterns

“…Regional distribution patterns and salinity tolerance experiments could not provide a clear picture of the factors controlling its distribution. Although it is assumed to be a brackish-water species (Vinogradov et al 1995a(Vinogradov et al , 1995bLischka et al 2001), it was found in this study at many stations with high oceanic salinities. We also could not detect any trend in the vertical distribution.…”

“…At some stations it reached up to 30%. Similarly, in the very shallow part of the Laptev Sea close to the rivers Lena and Yana, it also built the bulk of zooplankton abundance and biomass (up to 64% total biomass; Lischka et al 2001). Regional distribution patterns and salinity tolerance experiments could not provide a clear picture of the factors controlling its distribution.…”

“…In the Laptev and Kara Seas, it is a dominant component of the zooplankton communities (Vinogradov et al 1995a(Vinogradov et al , 1995bLischka et al 2001;Fetzer et al 2002). These shelf seas are characterized by an extreme seasonality of freshwater inflow through Siberian rivers.…”

Spatial variations in reproductive characteristics of the small copepod Oithona similis in the Barents Sea

“…This can be considered as a relatively large contribution in comparison with other Arctic regions. For example, in the Laptev Sea O. similis accounted for 2.2 to 4.4% of the total mesozooplankton biomass during late summer (Kosobokova et al 1998, Lischka et al 2001. In Canadian Basin waters, the species averaged 1.6% (Hopcroft et al 2005).…”

A 12-year study of the seasonal and interannual dynamics of mesozooplankton in the Laptev Sea: Significance of salinity regime and life cycle patterns

“…Peculiarities of the brackish-water calanoids habitats in this region were shortly described by Pirozhnikov (1985). Little is known about pelagic fauna in various bays of the Laptev Sea since the few publications available offer only little information about species composition, abundance and biomass distribution in summer (Pirozhnikov, 1955(Pirozhnikov, , 1958Pirozhnikov and Shul'ga, 1957;Botvinnik and Vershinin, 1958;Serkina, 1969;Abramova, 1996a;Lischka et al, 2001) and in winter (Lutsik et al, 1981). (1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000).…”
