The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

Marine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...

Do short-term, reduced-volume methods accurately reflect chronic toxic effects in the cladoceran Ceriodaphnia dubia? A study with the reference toxicant hexavalent chromium

Frontiers in Environmental Science, 2023
Cladocerans are frequently used as test organisms in aquatic toxicology studies. For practical reasons (bioethical and economic), efforts are currently made in search of alternative animal models and in defining short-lasting test methods that will allow
