Abstract The increasing use of image-based observing systems in marine ecosystems allows for more quantitative analysis the ecological zonation zooplankton. Developing methods that take advantage these can provide an increasingly nuanced understanding how morphometric characteristics (especially size) are related to distribution, abundance and ecosystem function via a wider application allometr...

The epiplankton community was investigated during Meduza cruises along south north and offshore – inshore transects in the middle and southern Adriatic in spring 2002. The diel and vertical distribution of heterotrophic bacteria, phytoplankton pigment composition, microand mesozooplankton were assessed. At most stations we observed a thermocline at approximately 20 m and a prominent chlorophyll...

The calanoid copepod, Acartiabispinosa Carl, 1907, is reported for the first time in the Red Sea, where it is found to be an important copepod in the mesozooplankton community structure of the Sharm El-Maya Bay. Female and male are fully redescribed and illustrated of as the mouthparts of this species have never previously been described and figured. Acartiabispinosa was collected in the plankt...

Phytoplankton size and relations between phytoplankton and microzooplankton (ciliates and heterotrophic dinoflagellates) biomass are analysed in 12 globally distributed areas. In view of the results, a hypothesis is posed where blooming species are those able to escape control by microzooplankton through a combination of predation avoidance mechanisms (e.g. larger size, colonies, spines, and to...
