The population structure of Sagitta setosa from the south-western part Black Sea was examined between May 1994 and December 1996. In addition, vertical distribution diel migration S.setosa were studied for juveniles (≤5 mm) adults (>5 in April 1995, September 1995 June studies showed that a new generation introduced September. Breeding most intensive to November, indicated by frequency small-sized individuals. Diel depth oxygen minimum zone surface observed adult but not juveniles. Juveniles...
Among non-native copepods, the calanoid Pseudodiaptomus marinus Sato, 1913 is species probably spreading at fastest pace in European and neighbouring waters since its first record Adriatic Sea 2007. In this contribution, we provide an update on distribution of P. Mediterranean Black Seas, along Atlantic coasts Europe, English Channel southern North Sea. Starting from a previous overview, include here original recently (2019–2023) published data to show novel introduction different...
Oithona davisae Ferrari and Orsi, 1984 (Copepoda: Cyclopoida) is a new copepod species recently entered into the Black Sea presumably with ballast waters.The first few individuals of this (ovigerous females, males late copepodites -maximum 18 ind.m-3) were found in Sevastopol Bay December 2001 identified initially as brevicornis (Zagorodnyaya 2002).However, later was re-examined proved to be O. (Temnykh Nishida 2012).
The seasonality of abundance and live/dead compositions copepods was studied in the northeastern Mediterranean Sea. Zooplankton, chlorophyll-a, PO4 sampling performed on a monthly basis from March 2006 to February 2007 at both coastal station an open water station. At station, high phytoplankton biomass driven by input Lamas River. On annual average, copepod 53,075 140,227 ind. m-2 stations, respectively. most common taxa were Oithona similis, Euterpina acutifrons, Labidocera spp., Oncaea...
The zooplankton species Oithona davisae is indigenous to coastal areas of Japan and the China Seas. It has, however, successfully invaded many other marine regions such as San Francisco Bay, Mediterranean Sea, North Sea Black Sea. transported most probably in ballast water tanks. This first report O. southern (Anatolian coast). Based on monthly plankton sampling at two stations (Sürmene Bay), seasonal dynamics were investigated. highest abundance occurred station (49,761 ind. m−3) December...

Feeding of non-indigenous cyclopoid copepod Oithona davisae in natural coastal phytoplankton assemblages from the Sevastopol Bay, Black Sea, late July and November 2013 artificial assemblage (mixture 5 cultured microalgae) have been studied laboratory experiments using flow cytometry.Three distinct main clusters (2 μm < ESD 20 μm) were identified water samples both sampling period: photosynthetic picoeukaryotes, nanophytoplankton nanoplanktonic cryptomonads (NanoPE).Female O. grazed on all 3...
Abstract. The extracellular concentration of H2O2 in surface aquatic environments is controlled by a balance between photochemical production and the microbial synthesis catalase peroxidase enzymes to remove from solution. In any kind incubation experiment, formation rates equilibrium concentrations reactive oxygen species (ROSs) such as may be sensitive both experiment design, particularly regulation incident light, abundance different groups, cellular catalase–peroxidase enzyme differ...
Abstract The occurrence of the invasive nonindigenous copepod Oithona davisae Ferrari and Orsi, 1984, is reported for first time in Aegean Sea. data we collected August 2017 from 14 stations along Turkish coast Sea reveal spatial distribution O. between openning Dardanelles Strait north Izmir Bay south. individuals, seven mesozooplankton samples a single station, were consistently found inner part April 2015‐October 2016. abundance female ranged 4 ind./m 3 2015 to 31,524 July 2016...
Egg production rates (EPRs) of Calanus euxinus were measured in the Black Sea during October 2000 and May 2001. EPRs generally low, on average 1.7 eggs female−1 day−1 3.9 The relationships between gonad maturity, depth-integrated chlorophyll a (Chl a) mean surface layer temperature examined. not related to Chl a, but negatively correlated with temperature. strongly proportion mature females. Growth C. derived from EPRs. growth rate was 0.011 0.03 significantly concentrations, female weight
