“…Also, new aliens are reported from the Mediterranean with increasing frequency (Flagella et al, 2009;Wolf et al, 2012;Katsanevakis & Crocetta, 2014;Aragay et al, 2016). More than 115 introduced benthic algae and seagrass taxa have been recorded in the Mediterranean (Mineur et al, 2015), mainly transferred through the Suez Canal (known as "Lessepsian invaders"; Katsanevakis & Crocetta, 2014), with ballast water, water currents and other organisms identified as vectors of transportation. Lessepsian invaders have had a major impact on benthic communities in the eastern Mediterranean (e.g.…”

The genus Ulva (Chlorophyta) is ubiquitous along Israeli Mediterranean shores where it has been studied extensively due to its important ecological role and potential value in biotechnology and aquaculture. Previous identifications of Ulva in Israel were based only on morphology. Here, we compare species found in 2002 and in 2014-2016. Analyses of ribulose-1,5-bisphosphate carboxylase/oxygenase (rbcL) and elongation factor 1-alpha (tufA) plastid genes (2014-2016 samples only), combined with morphological data, identified six Ulva species, three of which are new records for Israel and probably originate from the Indo-Pacific. Ulva compressa, rarely found in 2002, is now the most abundant species and exhibits two fairly distinct morphologies correlated with different haplotypes for both genes. Ulva fasciata was found more commonly in 2002 than in 2014-16, whereas the morphologically similar, and closely related, invasive species U. ohnoi seemed more frequent in recent samples. The finely branched tubular Ulva tepida was found in 2002 and 2015/16, and U. chaugulii and Ulva aragoensis (Bliding) Maggs, comb. nov. were discovered for the first time in 2015/16. The changing Ulva flora of the Israeli Mediterranean may be correlated with major environmental changes including 3°C increase in sea surface temperatures over the last two decades, as well as a generally increasing prevalence of non-native species. The local Ulva species now found in Israel could be of value for various industrial uses.

“…They are highly valued for recreational uses such as rock-pooling, angling, snorkelling and 3.7 Intertidal rocky habitats environmental education (Firth et al, 2013a). As coastal habitats become increasingly threatened by a number of interacting pressures (Thompson et al, 2002;Knights et al, 2013), and canopy algae are suffering widespread declines in many parts of the world (Airoldi and Beck, 2007;Connell et al, 2008;Mangialajo et al, 2008;Mineur et al, 2015), conservation of rocky shores becomes increasingly important to ensure maintenance of these essential ecosystem services.…”

“…Non-indigenous marine species are introduced into new areas primarily as a result of accidental transport via culture of exotic shellfish or shipping (by fouling or ballast tank emptying) (�ou-(�ou-douresque & Verlaque, 2002;Ribera Siguan, 2003;Streftaris et al, 2005;Zenetos et al, 2006;Galil, 2009). In this context, more than 115 introduced benthic algae and seagrass taxa have been found in the Mediterranean Sea (Zenetos et al, 2010;Mineur et al, 2015;Verlaque et al, 2015).…”

Phenological and molecular studies on the introduced seaweed Dictyota cyanoloma (Dictyotales, Phaeophyceae) along the Mediterranean coast of the Iberian Peninsula

et al. 2016

Dictyota cyanoloma, a distinctive brown algal species characterized by a blue-iridescent margin, was recently reported as an introduced species in the Mediterranean Sea (Steen et al., 2016) but little is known about its distribution dynamics, morphological plasticity and genetic structure. In the present integrative study, we evaluate its past and present occurrence along the Mediterranean Iberian coast, assess the species’ phenology in Palamós (Girona, Spain) and analyze the haplotype diversity by sequencing 49 individuals from nine sampling sites for different chloroplast and mitochondrial DNA regions. Although D. cyanoloma currently occurs along the Mediterranean Iberian coast (in 19 of 36 localities sampled between Algeciras and Llançà, mostly in marinas and harbour environments), we were not able to find any herbarium material of this species (at BCN-Phyc and MA) predating the year 1987. In Palamós, D. cyanoloma is present all through the year, with a maximum development in winter and a minimum in summer. Fertile specimens are absent during summer (July and August). Sporophytes are dominant from January to June and dioecious gametophytes were found only in February, March and June. Information about the antheridia, which has never been described before, is provided. Two chloroplast and three mitochondrial haplotypes were observed, indicating that multiple introductions of D. cyanoloma occurred in the study area. Additionally, the genetic structure suggests that spread did not occur through simple advancing wave fronts but by several long-distance dispersal events. Further studies employing microsatellite markers could potentially offer a better resolution to unravel expansion and colonisation dynamics of D. cyanoloma in the Mediterranean Sea.
