Multi-day experiments were carried out with two Marmara Sea calanoid copepod species: Acartia clausi and Centropages typicus, to assess the possible role of the type of feeding on the consumption of microplastics and its influence on the rate of energy metabolism of these species. In a mixture of microplastic beads (6 mu m diameter) and algae Rhodomonas salina (5-10 mu m size range) with equal concentrations of about 5000 cells/beads mL(-1) the ambush feeder A. clausi consumed almost 5 times less microplastic 858.8 +/- 294.1 beads ind(-1) day(-1) than the cruising feeder C. typicus and halved its consumption of microplastics alone, while C. typicus, on the contrary, increased its consumption rate of pure microplastics to 20237.4 +/- 7020.41 beads ind(-1) day(-1). Both types of reaction to microplastics lead to a decrease in the respiratory rates of the copepods. During the 5 days of maintenance on a solely microplastic diet, the respiration rates of A. clausi and C. typicus decreased 2.2 and 3.4 times, respectively, due to a decrease in the energy spent on motor activity, whilst maintaining basal metabolic energy. It has been shown that in A. clausi, consuming microplastics, a decrease in respiration rate occurs in the same way as in individuals starving in filtered water. A more rapid respiration rate decrease in Centropages typicus consuming microplastics may be due to the greater energy expenditure on microplastic beads capture and egestion via fecal pellets. Acartia clausi seems to exhibit a better strategy in dealing with the adverse consequences of microplastics consumption in comparison to Centropages typicus. (C) 2021 Elsevier B.V.

Allelopathic effects of the aquatic macrophyte Ceratophyllum demersum L. on phytoplankton species: Contrasting effects between cyanobacteria and chlorophytes Efeitos alelopáticos da macrófita aquática Ceratophyllum demersum L. Sobre espécies fitoplanctônicas: efeitos contrastantes entre cianobactérias e clorófitas
Alves Amorım, Cıhelıo; de Moura-Falcão, Rafael Henrique; Valença, Celina Rebeca; de Souza, Vitor Ricardo; Moura, Ariadne Do Nascimento (2019-01-01)
Aim: To assess the allelopathic effects of the submerged macrophyte Ceratophyllum demersum on four strains of phytoplankton species: two cyanobacteria (Microcystis aeruginosa-microcystin producing and M. panniformis-non-microcystin producing), and two chlorophytes (Ankistrodesmus falcatus and Raphidocelis subcapitata). Methods: A coexistence experiment between C. demersum and the four strains was carried out for six days, with eight treatments and three replicates. e strains were cultivated in ASM1 culture ...
Biochemically based modeling study of Antarctic krill Euphausia superba growth and development
Fach Salihoğlu, Bettina Andrea; Wolf-Gladrow, Dieter; Bathmann, Ulrich (2008-01-01)
A biochemical model of Antarctic krill Euphausia superba was developed to investigate the physiological mechanisms which enable krill to survive winter, when food is scarce. In this modeling approach data sets on the biochemical composition of krill and its food sources are combined into a model that takes food quality into account rather than just food availability during different seasons. Krill is defined in terms of protein, neutral lipid, polar lipid, carbohydrate, chitin, and ash content, and the mode...
Induced CYP1A mRNA, protein and catalytic activity in the liver of feral fish, leaping mullet, Liza saliens
Arinc, E; Kocabıyık, Semra; Su, E (2001-02-01)
In this study, we examined whether levels of P4501A mRNA expression were naturally induced in feral fish, Liza saliens, and whether CYP1A protein levels and associated enzyme activity, EROD, were also increased. Induction of mRNA was measured using a nucleic acid hybridization technique. For the hybridization studies, a new 33-mer oligonucleotide probe 5 ' -dCTC ATC CAG CTT CCT GTC CTC GCA GTG ATC AAT-3 ' was designed, which corresponded to the totally conserved amino acid motif of CYP1A protein from positi...
Trophic ecology and assessment of the predatory impact of the Moon jellyfish Aurelia aurita (Linnaeus, 1758) on zooplankton in the Black Sea
Anninsky, Borys E.; Finenko, Galina A.; Datsyk, Natalya A.; Kıdeyş, Ahmet Erkan (2020-01-01)
Experiments on the feeding of the Moon jellyfish Aurelia aurita have shown that digestion time of zooplankton typically varies between 2.2 and 5.1 h depending on the body weight of the predator, diet composition, amount of food, and seawater temperature. The daily ration of a Moon jellyfish with a wet body mass of 1 g reached 0.025-2.845 mg zooplankton.ind(-1).day(-1) corresponding to a carbon-specific food uptake of 0.2-9.1% C day(-1) with a mean value around 0.5% C day(-1). Such mesozooplankton consumptio...
Invasion dynamics of the alien ctenophore Mnemiopsis leidyi and its impact on anchovy collapse in the Black Sea
Oğuz, Temel; Fach Salihoğlu, Bettina Andrea; Salihoğlu, Barış (2008-12-01)
The mechanisms governing the unprecedented 1989-90 anchovy-Mnemiopsis shift event in the Black Sea were evaluated with a coupled model of bioenergetic-based anchovy population dynamics and lower trophic food web structure. Simulations showed that a combination of direct and density-dependent effects of overfishing, eutrophication-induced nutrient enrichment, climate-induced over-enrichment and temperature-controlled Mnemiopsis spring production were involved in the shift. Eutrophication made the system vuln...
