Toxicity test
Opis:: Cadmium wastewater released by human activities will eventually enter the aquatic environment. Living organism that lives around could potentially exposed by these cadmium, including C. gracilis which play a critical role as a primary producer. Cadmium can reduce the growth rate and pigment content in C. gracilis. Therefore, toxicity testing becomes important to do considering that C. gracilis has many benefits such as shrimp feed and have active compounds for antibacterial and biodiesel. Toxicity test was performed in 96-hours with a series of concentration 0, 0.56, 1.0, 1.8, 3.2, 5.6 mg/L. IC50 cadmium results in concentrated cell density and chlorophyll-a C. gracilis were 1.62 mg/L and 3.4 mg/L, while carotenoids were not in accordance with the contribution of cadmium. NOEC and cadmium LOEC to C. gracilis cell density were 0.56 mg/L and 1.0 mg/L.

Adriatic Sea
Opis:: Unusual occurrence of planktonic diatom species, Chaetoceros bacteriastroides and Chaetoceros pseudosymmetricus, was noticed in three different marine ecosystems of Adriatic Sea: the Krka Estuary and Telaščica Bay in the Central Adriatic, and in southern Adriatic offshore. From 2010 to 2015, these two Chaetoceros species were recorded in heterogeneous environmental conditions and in a very low abundances. Both species are regarded as very rare in world oceans, and consequently knowledge of their distribution and ecology is rather poor. Primarily described from tropical waters and showing Indo-Pacific distribution, C. bacteriastroides and C. pseudosymmetricus findings in Adriatic represent the northernmost records in world's oceans and seas. For C. pseudosymmetricus this is also the first occurrence in European seas. Areal expansion and introduction of new phytoplankton species in the Adriatic Sea might be related to different circulation regimes in the Ionian Sea and the concurrent rise in sea temperature in the Mediterranean in the last decade. Recent investigations have shown that entering currents, of either Atlantic/Western Mediterranean or Eastern Mediterranean origin, modify the composition of the plankton community in the Adriatic by bringing different newcomers.
