We studied the feeding behavior of nauplii and adult females marine cyclopoid copepod Oithona davisae in laboratory. Functional response experiments showed that O. can feed on a broad size range prey but high clearance rates only occur narrow range. Neither nor were able to Nannochloropsis oculata (2.5 µm), > 4 µm ingested. The highest occurred when offered dinoflagellate Oxyrrhis marina ciliate Strombidium sulcatum , respectively. preyed Acartia grani not their own species. Optimal :...
We studied the effects of future climate change scenarios on plankton communities a Norwegian fjord using mesocosm approach. After spring bloom, natural were enclosed and treated in duplicates with inorganic nutrients elevated to pre-bloom conditions (N, P, Si; eutrophication), lowering 0.4 pH units (acidification), rising 3°C temperature (warming). All nutrient-amended treatments resulted phytoplankton blooms dominated by chain-forming diatoms, reached 13–16 μg chlorophyll (chl) l−1. In...
Abstract Mixotrophs combine photosynthesis with phagotrophy to cover their demands in energy and essential nutrients. This gives them a competitive advantage under oligotropihc conditions, where nutrients bacteria concentrations are low. As the for mixotroph depends on light, competition between mixo- heterotrophic bacterivores should be regulated by light. To test this hypothesis, we incubated natural plankton from ultra-oligotrophic Eastern Mediterranean set of mesocosms maintained at 4...
The Northeastern Aegean Sea (NEA) is the area where Black waters (BSW) outflow in Mediterranean enhancing local productivity and inducing high hydrographic complexity. We describe structure distribution (both vertical horizontal) of mesozooplankton assemblages NEA during thermal stratification period July September 2003, an effort to identify BSW effects. overall standing stocks were much higher than those typically reported for other pelagic eastern Mediterranean. Higher abundance biomass...
Copepods have been considered capable of selective feeding based on several factors (i.e., prey size, toxicity, and motility). However, their behaviour as a function food quality remains poorly understood, despite the potential impact such process copepod fitness trophodynamics. In this study, we aimed to evaluate ability copepods feed selectively according nutritional value prey. We investigated performance calanoid Acartia grani under nutritionally distinct diets dinoflagellate Heterocapsa...

An important aspect of population dynamics for coral reef fishes is the input new individuals from pelagic larval pool. However, high biodiversity and difficulty identifying larvae closely related species represent obstacles to more fully understanding these populations. In this study, we combined morphology genetic barcoding (Cytochrome Oxidase I gene) characterize seasonal patterns fish community at two sites in close proximity reefs central-north Red Sea: one shallower inshore location...
Abstract Planktonic copepods are a key group in the marine pelagic ecosystem, linking primary production with upper trophic levels. Their abundance and population dynamics constrained by life history tradeoffs associated resource availability, reproduction predation pressure. The ageing process its underlying biological mechanisms are, however, poorly known. Our study shows that involves deterioration of their vital rates rise mortality an increase oxidative damage (lipid peroxidation);...
Abstract The Canary Current Large Marine Ecosystem (CCLME), extending from Cape Spartel in Morocco to Guinea-Bissau, supports high primary and fisheries productivity driven by permanent or seasonal upwelling activity. During the current study, mesozooplankton hydrographic sampling were conducted across CCLME spring/summer of 2017 autumn/winter 2019. total abundance dry weight found be higher 2017, partly due summer reproduction cycle diplostracans. A prominent latitudinal gradient was...
Although copepods have been considered tolerant against the direct influence of ocean acidification (OA) projected for end century, some recent studies challenged this view. Here, we examined impact short-term exposure to a pCO2/pH level relevant year 2100 (pHNBS, control: 8.18, low pH: 7.78), on physiological performance two representative marine copepods: calanoid Acartia grani and cyclopoid Oithona davisae. Adults both species, from laboratory cultures, were preconditioned four...
Patterns in the mesoscale distribution of larval fish coastal waters central Greece, an area high topographic and bathymetric complexity, were analysed using samples collected during two ichthyoplankton surveys July 1998 June 1999. Salinities lower eastern (Aegean) part study due to influence originating from Black Sea. In this region, larvae many epipelagic benthopelagic (typically summer spawning) species less abundant 1999, when significantly cooler, compared 1998. Multivariate analyses...
Abstract Rising levels of atmospheric CO2 are responsible for a change in the carbonate chemistry seawater with associated pH drops (acidification) projected to reach 0.4 units from 1950 2100. We investigated possible indirect effects acidification on feeding, fecundity, and hatching success calanoid copepod Acartia grani, mediated by potential CO2-induced changes nutritional characteristics their prey. used as prey autotrophic dinoflagellate Heterocapsa sp., cultured at three distinct...
Clausocalanus is a small-sized copepod genus that widespread in the world ocean, but it has been poorly investigated from biological and ecophysiological point of view. In this study, we targeted species lividus, one less studied circumglobally occurring congeners genus, to explore number aspects its feeding. We examined functional feeding response adult wild females seven monospecific diets with prey items differing terms size (ESD: 4–28 μm) motility. lividus did not significantly clear...
We assessed the effects of nutrient imbalanced diets on feeding, reproduction and gross-growth efficiency egg production copepod Paracartia grani. The cryptophyte Rhodomonas salina, cultivated under balanced (f/2) growth conditions (N P limitation), served as prey. Copepod C:N C:P ratios increased in treatments, particularly limitation. Feeding rates did not differ between N-limited treatments but decreased found no evidence compensatory feeding P. C averaged 0.34 treatment declined to...
