“…During the same time, P. marinus was recorded even farther north on the coast of California (Orsi & Walter, 1991) and was still present among the numerous alien species of the San Francisco estuary 10 years later (Choi et al, 2005). In 1998, P. marinus was detected for the first time in the coastal area of Todos Santos Bay (Baja California, Mexico), and further surveys in 2002 confirmed that the species was established in this area (Jiménez-Pérez & Castro-Longoria, 2006).…”

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.

Identifying non-invasible habitats for marine copepods using temperature-dependent R 0

If a non-indigenous species is to thrive and become invasive it must first persist under its new set of environmental conditions. Net reproductive rate (R 0 ) represents the average number of female offspring produced by a female over its lifetime, and has been used as a metric of population persistence. We modeled R 0 as a function of ambient water temperature (T) for the invasive marine calanoid copepod Pseudodiaptomus marinus, which is introduced to west coast of North America from East Asia by ship ballast water. The model was based on temperaturedependent stage-structured population dynamics given by a system of ordinary differential equations. We proposed a methodology to identify habitats that are non-invasible for P. marinus using the threshold of R 0 (T) \ 1 in order to identify potentially invasible habitats. We parameterized the model using published data on P. marinus and applied R 0 (T) to identify the range of non-invasible habitats in a global scale based on sea surface temperature data. The model predictions matched the field evidence of species occurrences well.
