“…However, only a few studies have focused on the motion of males, females and ovigerous females of the same species (e.g. Dur et al 2010;Michalec et al 2010Michalec et al , 2012. Our results show significant sex-dependent differences in the swimming behaviour of P. marinus, in contrast to the feeding modes that are similar between males and females (Uye and Kasahara 1983).…”

“…All resulting trajectories were singularly plotted and assessed visually, disregarding excessively noisy tracks. The tracks were analysed following the protocol of Dur et al (2010) in order to allow a comparison between P. marinus and P. annandalei . In particular, the motion of the copepods was quantitatively analysed evaluating the speed and the swimming/rest time, and using symbolic analysis Moison et al 2009;Schmitt et al 2006;Vandromme et al 2010).…”

“…the average amount of time that a copepod spent in a particular state consecutively, as well as a study on the transition probability, considering the chances of transition from one state to all the others were calculated. Both the residence time and the transition probability were represented as probability distribution functions as in Dur et al (2010). The cases in which movement is completely random are defined by a first-order Markovian Figure 1 Examples of individual trajectories of (a) males, (b) non-ovigerous females and (c) ovigerous females of P. marinus.…”

Background: The calanoid copepod Pseudodiaptomus marinus Sato, 1913 is an estuarine-coastal species, living in shallow eutrophic inshore waters. It is native of the Indo-Pacific region, but in the last 50 years, it has successfully colonized new areas worldwide. P. marinus, first recorded in Lake Faro (Messina, Italy) in October 2008, is now a stable component of the zooplankton assemblage of the lake. By means of video recordings, for the first time, the swimming behaviour of males and non-ovigerous and ovigerous females of P. marinus has been studied. The individuals were filmed in the presence and absence of food to evaluate how the presence of prey might affect the swimming behaviour. Results: The swimming motion showed marked sex-dependent features and responses to the presence of food. Mechanisms through which behaviour might influence the outcome of a new colonization were analysed. The behaviour of P. marinus was then compared with that of the congeneric Pseudodiaptomus annandalei showing the typical behaviour displayed by the representatives of the genus Pseudodiaptomus of living in proximity of the bottom.

“…The typical behavior displayed by the representatives of the family Pseudodiaptomidae, that is, remaining attached to the substrate for most of the time (Fancett & Kimmerer, 1985;Dur et al, 2010), is displayed more frequently by P. marinus females than males (Sabia et al, 2014). Sticking to the substrate may be a winning strategy for hiding from visual predators while creating feeding currents to acquire detrital food items.…”

The Mediterranean Sea is one of the most affected areas by alien invasions, which are continuously increasing due to the intense human activities and environmental changes that favor the introduction of species previously unable to colonize the basin. This is the case of the copepods of the genus Pseudodiaptomus, first described in the Indian Ocean and considered as one of the most resistant to unfavorable conditions but never recorded in the Mediterranean until 2011 though present in adjacent seas. Pseudodiaptomus marinus, in particular, is common in shallow marine-brackish waters and is one of the species often found in ballast waters and in aquaculture plants. Native of Japan, it has started spreading since 1950s, and its populations have established in several harbors, eutrophic inlets, and lagoons along the coasts of the Pacific and Indian Oceans. In the last few years, P. marinus has been increasingly reported in European Seas (Mediterranean Sea and North Sea).In this article, we review the invasion history of this species with a special emphasis on its records in the Mediterranean Sea, and its occurrence and establishment in Sicilian waters. We also compare the biological traits and population dynamics of P. marinus with those of other representative of the genus and discuss about the possible mechanisms of introduction in new environments. The aim of this work is to understand the reasons of successful invasion of P. marinus and the environmental and biological factors that may lead to its further biogeographic expansion.

Further work is needed to entangle the fractal complexity of behavioral properties and to generalize the use of fractal-based approaches to stress assessment in marine invertebrates.…”
