HRZZ: Utjecaj okolišnog stresa na pojavnost i međudjelovanje biološki važnih organskih molekula i mikronutrijenata u morskom ekosustavu (AMBIOMERES)
Glavni istraživač
Recently documented oligotrophication of the Adriatic Sea caused by global changes opened questions how this reflects on the quality and quantity of organic matter (OM) produced by the phytoplankton and on the consequent influence on the micronutrient metals availability and cycling. Within the project, a progressive (model and in-situ) approach will be accomplished to reveal crucial alterations in the marine ecosystem. Initial investigations will imply model experiments on the interaction of selected OM (polysaccharides, lipids, polymeric organic matter containing N catalytic atoms) with micronutrient metals (Fe, Co, Cu, Zn and Cd). Additionally, phytoplankton monoculture incubation under various growth conditions (nutrient concentrations and temperature variations) will be included in order to comprehend multiple impacts on the phytoplankton OM production and micronutrients metals distribution. Model experiments will be followed by in-situ investigations at the selected oligotrophic and eutrophic areas of the Adriatic Sea.
This will give holistic informations on the natural marine biochemical cycles and linkage between OM and micronutrient metals. In-situ investigations will be focused on the seasonal variations of the OM and micronutrient appearance and concentrations in combination with physico-chemical parameters (temperature, salinity, pH, O2), and dissolved and particulate organic carbon content, surface-active organic substances and macronutrients (PO4, NO3, NO2, NH4). These investigations will be conducted by intercomparable and multimethodological approaches using various chromatographic to electrochemical techniques. Finally, taking into account all obtained results an important part of the natural marine ecosystem processes will be characterized in the prospective of climate changes.
Simplified schematic of assumed interactions between micronutrient metals (M=Fe, Cu, Co, Zn, Cd) and organic molecules (lipids, acidic polysaccharides and N-POM) released from phytoplankton in conditions of (A) oligotrophy and (B) eutrophy. Biological processes drive production of OM and speciation of micronutrient metals:
(A) Micronutrient metals (hydrated ionic form, M, or inorganic complexes, MX) interact with released OM forming complexes from which cells easily take micronutrient metal by ligand exchange reactions. This is mechanism through which OM enhance bioavailability of micronutrient metals in deficiency.
(B) In eutrophy phytoplankton produce altered organics that form complexes with micronutrient metals which do not enable micronutrient metal uptake by cell. This is mechanism through which OM is reducing toxicity of micronutrient metals when they are in surplus. There are enough micronutrients in inorganic form which are preferable for the cellular uptake.

Terenski rad
U sklopu projekta proveli smo uzorkovanje morske vode na sjevernom Jadranu, na transektu Rovinj ušće rijeke Po, na dvije postaje 107 i 108 (Slika D6.1.1). Izbor postaja je određen trofičkim statusom same postaje. Postaja 107 je oligotrofna (nedostatak hranjivih soli) dok je postaja mezo- do eutrofna (koncentracija hranjivih soli povoljna do prevelika). Uzorkovane su tri dubine 0, 5 i 10 m. Uzorkovali smo pomoću istraživačkog broda „Vila Velebita“ Instituta Ruđer Bošković. Uzorkovanja su provedena mjesečno, uključujući datume: 16. studenog 2016, 12. prosinca 2016, 27. siječnja 2017, 17. veljače 2017, 28. ožujka 2017, 03. svibnja 2017, 12. lipnja 2017, 12. srpnja 2017, 30. kolovoza 2017 i 04. listopada 2017

Izabrane su dvije postaje, čiste estuarijske vode i vode pod utjecajem istovarne luke u Šibeniku. Uzorkovane su 3 dubine: zaslađena voda 0 m, haloklina oko 2m, i slani sloj na 20 m. Uzorkovanja su provedena u četiri sezone, u studenom 2017 te siječnju, travnju i srpnju 2018. g.
