Mesozooplankton Dynamics in the Aegean Sea

2020
Zooplankton plays a fundamental role in oceanic carbon flux as the primary biological mechanism sequestering the carbon transferred from the atmosphere into surface waters to deeper layers and higher trophic levels. Studies of the zooplanktonic organisms of the Aegean Sea have been initiated in the 1900s, whereas the number of cruises has increased ...

Mesozooplankton structure in Dolgaya Bay (Barents Sea)

Polar Biology, 2009
The community structure of mesozooplankton was investigated in Dolgaya Bay (southern Barents Sea), a subarctic fjord, using a Juday net (0.168-mm mesh size) in July, 2008. A total of 39 species and higher taxa were found. Average abundance, biomass and diversity (±standard error) were 153,403 ± 15,855 ind m−2, 570 ± 61 mg dry mass m−2, and 2.25 ± 0.09,

Mesozooplankton in the Arctic Ocean in summer

Deep Sea Research Part I: Oceanographic Research Papers, 1999
The biomass, species and chemical composition of the mesozooplankton and their impact on lower food levels were estimated along a transect across the Arctic Ocean. Mesozooplankton biomass in the upper 200 m of the water column was signi"cantly higher (19}42 mg DW m~3) than has previously been reported for the Arctic Ocean, and it reached a maximum at ...

Mesozooplankton affinities in a recovering freshwater estuary

Estuarine, Coastal and Shelf Science, 2016
Abstract Water quality of the Scheldt estuary (Belgium/The Netherlands) has considerably improved in recent years, especially in the upstream, freshwater reaches. Within the zooplankton community, the copepod Eurytemora affinis , typically abundant in brackish water and quasi-absent from freshwater before 2007, has since substantially developed in ...

MESOZOOPLANKTON IN SAMARA-CITY URBAN POND

Practice Oriented Science: UAE – RUSSIA – INDIA
The Rotatoria species count in urban pond has reduced from 57 to 26 within 7 years. Crustacea species count – from 33 to 21. Zooplankton abundance has reduced significantly. It is suggested that Zooplankton population size is caused by the pond pollution and water volume reduce due to global warming.

Mesozooplankton community characteristics in the NE subarctic Pacific

Deep Sea Research Part II: Topical Studies in Oceanography, 1999
Mesozooplankton biomass, species composition, abundance, and vertical distribution were determined along a transect from the continental slope off the west coast of Canada to Ocean Station Papa (OSP) in the open-ocean waters of the NE subarctic Pacific as part of the Canadian Joint Global Ocean Flux Study of this area.

Seasonal Dynamics of Mesozooplankton in Brazilian Coastal Waters

Hydrobiologia, 2006
The composition, numerical abundance and seasonal distribution of mesozooplankton, in addition to copepod biomass, were studied in the Sao Sebastiao Channel (SSC) during different seasonal periods and hydrographic regimes. Two stations were sampled every 3 months from January 1996 to July 1997 and also in July 1998 and January 1999.

Ammonium regeneration by Antarctic mesozooplankton: an allometric approach

Marine Biology, 2001
Given the importance of copepods in the Southern Ocean food web, there are few assessments of their N budgets or their role in regenerating N. In this study we measured elemental composition and ammonium-excretion rates of copepods and small euphausiids, and estimated the role of metazoans in recycling ammonium in the South Georgia region.
