Microzooplankton Communities in a Changing Ocean: A Risk Assessment
(MDPI, 2021-02-26)
Microzooplankton communities are fundamental components of marine food webs and have the potential to impact the functioning of carbon pumps. The identification of common responses of microzooplankton to global change has ...
Biomasss and microzooplankton seasonal assemblages in the Bahía Blanca Estuary, Argentinean Coast
(Cambridge University Press, 2011-12)
We investigated the occurrence and seasonal variation of the biomass of rotifers, tintinnids, the heterotrophic dinoflagellate Gyrodinium fusus and copepod nauplii in the Bahı´a Blanca Estuary (38842′ S61850 ′ W), Argentina, ...
Allochthonous carbon is a major driver of the microbial food web – A mesocosm study simulating elevated terrestrial matter runoff
(Elsevier, 2017-08)
Climate change predictions indicate that coastal and estuarine environments will receive increased terrestrial runoff via increased river discharge. This discharge transports allochthonous material, containing bioavailable ...
Seasonal changes in microzooplankton feeding behavior under varying eutrophication level in the Bahía Blanca estuary (SW Atlantic Ocean)
(Elsevier Science, 2016-04)
Dilution experiments were conducted during a two-year survey in the Bahía Blanca estuary (SWAtlantic Ocean) to evaluate seasonal variations of microzooplankton grazing (m) and phytoplankton growth (μ). The trophic interactions ...
Contribution of planktonic and detritic fractions to the natural diet of mesozooplankton in Bahía Blanca estuary
(Springer, 2008-10)
The relative importance of phytoplankton and microzooplankton in the natural diet of mesozooplankton was assessed in Bahía Blanca Estuary, Argentina, in December 2005. Grazing experiments were performed using 200-to-2,000 ...
Micro and mesozooplankton composition during winter in Ushuaia and Golondrina Bays (Beagle Channel, Argentina)
(Instituto Oceanográfico, 2007-06)
The current paper analyses the micro and mesozooplankton in Ushuaia and Golondrina Bays, the first research on these plankton fractions of these areas in wintertime (August 2004). The number of microzooplankton and ...
Land use and basin characteristics determine the composition and abundance of the microzooplankton
(Springer, 2011-06)
The influence of watershed land use on microzooplankton was examined. Six rivers and a shallow lake located in rural (agriculture, livestock) and urban areas were sampled during 4 weeks at low water, low temperatures and ...
Pigment-specific rates of phytoplankton growth and microzooplankton grazing in a subtropical lagoon
(Journal of Plankton Reseach, 2006)
Phytoplankton growth and microzooplankton grazing rates were evaluated in one station in Bahía Concepción, located in the middle region of the Gulf of California, México. We used high-performance liquid chromatography ...
Eutrophication disrupts summer trophic links in an estuarine microbial food web
(Elsevier Inc, 2019-09-21)
Eutrophication is the most widespread effect of urban development in coastal areas. To elucidate how nutrient loading affects the carbon pathways at the base of food chains, we quantified the carbon transfer among microbial ...
Micro- and mesozooplankton successions in an Antarctic coastal environment during a warm year
(Public Library of Science, 2020-05-14)
The rapid increase in atmospheric temperature detected in the last decades in the Western Antarctic Peninsula was accompanied by a strong glacier retreat and an increase in production of melting water, as well as changes ...
