“…Short‐term trials were aimed at testing the ability of adults to adapt to changing environmental conditions, establishing a stable population in a receiving area. The culture established in November 2016 produced a 1:1 assemblage of both sexes at 21.0 ± 2.0°C, in compliance with the typical sex ratio reported in the literature during peak periods (Deschutter et al, ; Liang & Uye, ; Lučić, Mozetič, Francé, Lučić, & Lipej, ; Uye et al, ), as well as with the gender ratio recorded in situ during the sampling. Since the salinity lethal effect was tested, individuals could not be used twice.…”

“…Moreover, the absence of copepodites, a female‐skewed population and the absence of egg‐producing females in winter (Uye et al, ) indicate that adult females might be more prone to the induction of a dormant strategy than other developmental stages. The adoption of this type of dormancy might allow P. marinus to bridge periods of environmental harshness, and could be used as a further trait potentially sustaining its spreading and facilitating the formation of successful local populations in areas characterized by low wintertime temperatures, such as along the Atlantic coasts of France and UK as well as in the North Sea (Deschutter et al, ; Wootton et al, ).…”

“…According to the review by Sabia et al (), P. marinus flourishes at salinities ranging from 30.0 to 37.0 psu, although showing a salinity window from 2.5 to 38.0 psu. In its native region, moreover, P. marinus is strongly thermophilic (Lee, Song, Park, & Choi, ; Uye, Iway, & Kasahara, ), although it has been found also at lower temperatures outside its optimal range (Brylinski et al, ; Deschutter et al, ).…”

Response to salinity and temperature changes in the alien Asian copepod Pseudodiaptomus marinus introduced in the Black Sea

The salinity tolerance and the effect of temperature were studied on the behavior and motor activity of the nonindigenous Indo‐Pacific calanoid copepod Pseudodiaptomus marinus, first found in Sevastopol Bay (Black Sea) in autumn 2016. According to the index of median lethal salinity (LS50), the salinity tolerance range of adult P. marinus collected at 18.0 psu in November 2016 and subsequently reared in the laboratory amounted to 5.0–44.0 psu, independently of the acclimation regime. Females of P. marinus collected in December 2016 at 12.0°C became torpid at 8.0°C, a value typical of winter–spring Black Sea coastal areas. An increase in temperature from 8.0°C to 27.0°C led to an increase in the beat frequency of mouth appendages, swimming speed, and time spent cruising. However, at the same high temperature, the mean cruising speed in the feeding‐current feeder P. marinus was 2‐fold lower than that of the native, similarly sized cruise feeder Pseudocalanus elongatus. On the contrary, mouthpart beat frequency while cruising was 2‐fold higher reaching 80 Hz, due to the creation of feeding currents in P. marinus. The results of our experiments confirm the euryhaline character of P. marinus, and point to an apparent ability to survive cold temperatures in a torpid state. This suggests the possibility of entering an overwintering stage to survive the adverse cold winter–spring environmental conditions of the Black Sea, similarly to the recent thermophilic Indo‐Pacific invader Oithona davisae which established a successful population in the same area.

“…Zooplankton is ubiquitous in the BPNS, and is found in every season with densities up to 40.000 ind.m ‐3 (Van Ginderdeuren, ), although average densities are much lower at around 1–400 ind.m ‐3 (Van Ginderdeuren, ). Although the pelagic ecosystem is huge and of significant importance, it is scarcely studied in Belgian waters: recent studies on marine zooplankton in the BPNS are increasing (Van Ginderdeuren, Fiers, et al , ; Van Ginderdeuren, Hostens, et al , ; Van Ginderdeuren, ; Deschutter et al , ,; Mortelmans et al , ). In contrast, the Belgian estuarine zooplankton has received more attention throughout the time (Bakker and De Pauw, ; Soetaert and Van Rijswijk, ; Appeltans et al , ; Tackx et al , ; Mialet et al , ).…”

Through regular sampling surveys, the Flanders Marine Institute (VLIZ) is generating a long‐term data series for the Belgian coastal water and sandbank system, a designated site in the Long Term Ecological Research (LTER) network. The data series is built from sampling activities initiated in 2012 in the framework of the LifeWatch marine observatory. Nine nearshore stations are sampled monthly, with an additional eight offshore stations sampled seasonally. This paper presents the generated data series for zooplankton densities and size measurements, analysed using a ZooScan plankton imaging device together with the ZooProcess and Plankton Identifier software packages. To date 673.017 biological particles have been collected and identified. The collection and processing of the 2012–2018 dataset is described, along with its data curation and quality control. Yearly versions of the data are published in a standardized format together with environmental parameters, accompanied by an extensive metadata description and labelled with digital identifiers for traceability. The data are published under a CC‐BY 4.0 license, allowing use of the data under the condition of providing the reference to the original source.

Since 2007, the non-indigenous calanoid copepod Pseudodiaptomus marinus Sato, 1913 has been increasingly recorded in numerous European sites, spreading at an unexpectedly fast pace over a short time-span. This species presents specific biological and behavioural traits which make it of particular interest for ecological and applied research topics. On 29-30 January 2018, 29 scientists from nine European Countries established the EUROBUS (Towards a EURopean OBservatory of the nonindigenous calanoid copepod Pseudodiaptomus mar-inUS) Working Group (WG). This WG aimed at creating a European network of institutions and researchers working on the various aspects of the Electronic supplementary material The online version of this article (
