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 production and grazing in the Arabian Sea

Deep Sea Research Part II: Topical Studies in Oceanography, 2000
Abstract Growth rates, grazing and fecal pellet production by mesozooplankton size classes in the surface 200 m are compared over two inshore/offshore transects in the Northern Arabian Sea during different monsoon seasons. We derived these rate parameters from measured biomass and several empirical models that estimate copepod production from ...

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 ...

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.

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,

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.

Distribution and Ecology of Mesozooplankton in the Northern and Central Adriatic Sea

2001
Within the framework of the Prisma 2 Project, four oceanographic cruises were carried out in the central and northern Adriatic Sea from June 1996 to March 1997. Samples were collected both by BIONESS electronic multinet (204 samples from 54 sites) and by WP2 (101 samples from 19 sites) along inshore-offshore sections.

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.

Mesozooplankton of the Scotia Sea: present, past and future [PDF]

, 2018
The potential impact of global warming on plankton populations and processes in the Southern Ocean is cause for concern. Greatest attention has concentrated on Antarctic krill, a keystone macroplankton species and currently the object of a commercial fishery.
