“…The genetic results of four different haplotypes found in the five analyzed individuals from introduced populations (two from Venice Lagoon and three from Ebro Delta, one of which is shared) argue against colonization events based on single female lineages in both populations and suggest that the European populations do not have strong genetic bottlenecks. This has also been shown for the second introduced panopeid crab in Europe, Rhithropanopeus harrisii (see Projecto-Garcia et al 2010).…”

“…The Mediterranean Sea has been exceptionally susceptible to biological invasions, especially after the opening of the Suez Canal and the connection to the Indo-Pacific via the Red Sea (Galil et al 2002). Among others, two species of Panopeidae have established large populations in estuarine habitats of the Mediterranean and Black Sea, namely Rhithropanopeus harrisii (Gould, 1841) (see Projecto-Garcia et al 2010) and Dyspanopeus sayi (Smith, 1869). …”

SUMMARY:The panopeid crab Dyspanopeus sayi (Smith, 1869) is reported here from the Ebro Delta (Mediterranean coast of the Iberian Peninsula). Originally endemic to the Atlantic coast of North America, D. sayi was involuntarily introduced into Britain, France and the Netherlands, and into the Adriatic and Black Sea within the last thirty years. Here we provide the first record of this species from the western Mediterranean Sea. Occurrences of ovigerous females at different localities of the delta and in different years provide evidence that the population is well established. Mitochondrial DNA confirms the identity of the species and indicates that the introduced population consists of at least three female lineages. The first zoeal stage of D. sayi was obtained in the laboratory from an ovigerous female captured in August 2010 with embryos in an advanced stage of development. The morphology of the zoea I is described here in detail and is similar to the one previously reported for native populations.Keywords: Dyspanopeus sayi, alien species, Mediterranean, Ebro Delta, mtDNA sequences, zoea.RESUMEN: Primera cita y evidencia de una población establecida del cangrejo americano Dyspanopeus sayi (Brachyura: Heterotremata: Panopeidae) en el Mediterráneo occidental. -Se informa de la presencia del cangrejo panopeido Dyspanopeus sayi (Smith, 1869) en el Delta del Ebro (costa mediterránea de la Península Ibérica). Originalmente endémica de la costa atlántica de América del Norte, D. sayi se introdujo en Gran Bretaña, Francia, los Países Bajos, en el Adriático y el Mar Negro en los últimos treinta años. En el presente trabajo se presenta el primer registro de esta especie en el Mediterráneo occidental. La presencia de hembras ovígeras en diferentes localidades del Delta del Ebro y en diferentes años evidencia que la población está bien establecida. El ADN mitocondrial confirma la identidad de la especie e indica que la población introducida consiste de por lo menos tres linajes de hembras. El primer estadio de zoea de D. sayi se obtuvo en el laboratorio a partir de una hembra ovígera capturada en agosto de 2010, con embriones en una etapa avanzada de desarrollo. La morfología de la zoea I se describe en detalle, siendo similar a descripciones anteriores de poblaciones oriundas.Palabras clave: Dyspanopeus sayi, especies invasoras, Mediterráneo, Delta del Ebro, secuencias de mtADN, zoea.

“…Since then, it has spread to locations around the North Sea and Baltic Sea, including Germany in 1936 (Schubert 1936), Poland in 1951 (Demel 1953), Lithuania in 2000 (Bacevičius and Gasiūnaitė 2008), Finland in 2009, and most recently Estonia in 2011 (Kotta and Ojaveer 2012) Projecto- Garcia et al (2010) examined the colonization event of other, older European populations of R. harrisii and was unable to pinpoint whether R. harrisii had a single successful invasion, or a series of successful invasions with different mechanisms (e.g., ballast water, hull fouling, as hitchhikers in the oyster aquaculture trade). Due to the large amount of shipping, both from the USA to Europe and within Europe since 1874, the possibility of a single successful invasion seems highly improbable, but there are no data to unequivocally confirm that conjecture at this time.…”

Florence, was a brilliant Italian zoologist and ethologist, and one of the most well-known and active experts on alien aquatic species. Since her masters degree in Biology (1979) and her PhD in Animal Biology (Ethology) (1987), both obtained at the University of Florence, Francesca studied the behaviour and ecology of aquatic animals. Initially, most of her research concerned social recognition in crustaceans: she was particularly renowned for her studies on hermit crabs and crayfish, her principal model organisms.Then, from the 1990's onwards she worked in the field of invasion biology, her main interest until her death. Francesca devoted herself with enthusiasm and energy, not only to the problem of the invasive red swamp crayfish Procambarus clarkii, by revealing several aspects of its behavioral ecology, and by developing with her collaborators different methods for its control, but she gradually became an international expert on crayfish and more generally on aquatic alien species. In all aspects of her life, she was constantly driven by a continuous curiosity, thirst for knowledge and a will to face challenges; this was expressed by exploring and frequently opening new research fields. And she transmitted her drive and passion to the many students she supervised. One of the last papers with her contribution is published in this issue of Aquatic Invasions by Vera Gonçalves, her Portuguese PhD student working on the interaction between Procambarus clarkii and the zebra mussel Dreissena polymorpha, an issue of recent increasing interest in Francesca's team.

“…Further improvements to sampling designs might include finer profiling of the water column, sampling for several consecutive days to permit time-series analysis, sampling sites concurrently, and using a complementary Lagrangian strategy of repeatedly sampling the same water mass. Until a temporally and spatially exhaustive sampling strategy is coupled with other approaches, such as individual based and numerical models (North et al 2008, Kim et al 2010, larval behavior mimics (Wolcott 1995), natural elemental tags (Levin 1990, Anastasia et al 1998, population genetics (Projecto-Garcia et al 2010), or parentage analysis (Berumen et al 2012), the roles of behavioral and physical processes in larval transport will not be fully resolved. …”

The maintenance of marine populations depends on the completion of larval migrations between adult and larval habitats, but the ability of microscopic larvae to regulate their movements in such a dynamic environment has been debated. Using a comparative hypothesis testing approach and intensive hourly sampling throughout the water column, we determined the ability of larvae of 6 species with different swimming abilities (2 gastropods, 2 crabs, 2 fishes) to overcome strong tidal mixing during spring tides and regulate their vertical, and hence, horizontal position, in opposing depth-stratified currents in the upper Hudson River estuary, USA. The vertical distributions of nonmotile eggs and swimming larvae generally differed, suggesting that larvae regulated depth. Eggs were passively mixed by tidal currents, but larvae typically aggregated in stratified portions of the water column, which fostered retention in the upper estuary. However, the capacity to regulate depth depended on swimming ability and the degree of mixing. In a predominantly mixed tidal environment upstream, mixing overcame most larvae when current velocities were maximal during mid-ebb or mid-flood tides; tidal vertical migrations were not evident for any species, and diel vertical migrations were apparent for only 1 species. In a partially stratified water column downstream, diel vertical migrations were apparent for larvae of 3 of 4 invertebrate species, and tidal vertical migrations were apparent for the 2 fish species. The presence of all larval stages showed that all species regulated depth sufficiently well to remain in the upper estuary. Regardless of swimming ability, larvae were retained in the estuary by occurring near the level of no net motion, even without completing tidal vertical migrations. Continuous profiling of larvae and hydrodynamics is necessary to reveal the ability of larvae to regulate depth in tidal mixing and recruit to adult populations.
