Plankton biodiversity around the Salento Peninsula (South East Italy): an integrated water/sediment approach

open access: yesScientia Marina, 2004
The microplankton community was studied at 9 sites (29 sampling stations) along the Salento Peninsula (SE Italy). Integrated samplings from both the water column (to collect active stages), and sediments (to collect resting stages), were carried out ...

Microzooplankton stoichiometric plasticity inferred from modelling mesocosm experiments in the Peruvian Upwelling region

open access: yesFrontiers in Marine Science, 2016
Oxygen minimum zones (OMZs) are often characterised by nitrogen-to-phosphorus (N:P) ratios far lower than the canonical Redfield ratio. Whereas the importance of variable stoichiometry in phytoplankton has long been recognised, variations in zooplankton ...

The trophic roles of microzooplankton in marine systems [PDF]

open access: yesICES Journal of Marine Science, 2008
Abstract Calbet, A. 2008. The trophic roles of microzooplankton in marine systems. – ICES Journal of Marine Science, 65: 325–331. Microzooplankton (here defined as <200 µm grazers) are key components of marine foodwebs. Their grazing significantly affects primary producers and usually exceeds that of mesozooplankton.

Trophic flexibility in larvae of two fish species (lesser sandeel, Ammodytes marinus and dab, Limanda limanda)

open access: yesScientia Marina, 2009
We investigated the trophic level of larvae of two fish species (lesser sandeel. Ammodytes marinus, and dab, Limanda limanda) in spring 2004 by means of stable isotope signatures at the helgoland roads station (54°11.18’N and 07°54.00’ E).

Impact of ocean acidification on microzooplankton grazing dynamics

open access: yesFrontiers in Marine Science
This study examines the potential impacts of projected atmospheric carbon dioxide (pCO2) levels reaching 800 ppm by the end of the century, focusing on ocean acidification effects on marine ecosystems in the coastal areas of Bohai.

Modelling the seasonal dynamics of marine plankton in the southern Baltic Sea. Part 1. A Coupled Ecosystem Model

open access: yesOceanologia, 2005
The paper presents a one-dimensional Coupled Ecosystem Model (1DCEM) consisting of three submodels: a meteorological submodel for the physics of the upper layer and a biological submodel, which is also driven by output from the physical submodel.

Micro- and nanoplastics in freshwater ecosystems—interaction with and impact upon bacterivorous ciliates

open access: yesFrontiers in Earth Science
The ubiquitous occurrence of microplastics and nanoplastics in aquatic environments is of major concern as these priority pollutants are readily ingested by a wide variety of aquatic organisms.
