Abstract Many protist plankton are mixotrophs, combining phototrophy and phagotrophy. Their role in freshwater marine ecology has emerged as a major developing feature of research over recent decades. To better aid discussions, we suggest these organisms termed “mixoplankton”, “planktonic that express, or have potential to phagotrophy”. The term “phytoplankton” then describes phototrophic incapable “Protozooplankton” phagotrophic protists do not engage acquired phototrophy. complexity the...
Abstract Harmful algal blooms kill fish populations worldwide, as exemplified by the haptophyte microalga Prymnesium parvum . The suspected causative agents are prymnesins, categorized A-, B-, and C-types based on backbone carbon atoms. Impacts of P. extracts purified prymnesins were tested epithelial rainbow trout gill cell line RTgill-W1 human colon cells HCEC-1CT. Cytotoxic potencies ranked A > C B-type with concentrations spanning from low (A- C-type) to middle (B-type) nM ranges....
An important functional trait of organisms is their trophic mode. It determines position within food webs, as well function an ecosystem. For the better part 20th century, aquatic protist communities were thought to consist mainly producers (phytoplankton) and consumers (protozooplankton). Phytoplankton cover energy requirements through photosynthesis (phototrophy), while protozooplankton graze on prey organic particles (phagotrophy). However, over past decades, it was shown that another...
Abstract It remains unclear as to how mixoplankton (coupled phototrophy and phagotrophy in one cell) affects the estimation of grazing rates obtained from widely used dilution technique. To address this issue, we prepared laboratory-controlled experiments with known mixtures phyto-, protozoo-, mixoplankton, operated under different light regimes species combinations. Our results evidenced that chlorophyll is an inadequate proxy for phytoplankton when are present. Conversely, species-specific...
Harmful algal blooms of Prymnesium parvum have recurrently been associated with the killing fish. The causative ichthyotoxic agents this haptophyte are believed to be prymnesins, a group supersized ladder-frame polyether compounds currently divided into three types. Here, development quantitative method assess molar sum prymnesins in water samples and biomass is reported. based on derivatization primary amine subsequent fluorescence detection using external calibrants. presence underivatized...
A new marine strain of picoplanktonic algae, PMPFPPE4, was isolated from a mixed net-phytoplankton sample taken the upper euphotic layer southeastern Adriatic Sea. Evaluation included morphological investigation (by light and electron microscopy), phylogenetic analysis (utilizing plastid 16S rRNA nuclear 18S genes), physiological characterization (screening pigment/lipid composition capturing photosynthesis measurements). The proven to belong genus Picochlorum lipid revealed an unexpected...
Chaetoceros peruvianus is a marine diatom species with circumglobal distribution. While frequently observed, it appears never to dominate the phytoplankton community hence can be characterized as rather opportunistic, generalistic species. Here we present ecological interpretations from long-term data set on microphytoplankton in northern Adriatic Sea, where abundancies and relative contributions of C. were observed along steep gradients. Limited supply dissolved inorganic phosphate was...
Abstract Marine life is threatened by global warming and its indirect consequences, which include, among others, increased stratification leading to phosphorus (P) nitrogen depletion in the upper water column. Phosphorus plays a key role all biochemical systems; storage of metabolic energy, formation genetic material, subcellular compartmentalization. Our multi‐year study lipid biogeochemistry northern Adriatic (Mediterranean), becoming warmer nutrient‐poorer, particularly regarding P, has...
