“…(Bouillon et al 2006), present in all aquatic ecosystems (Boero and Bouillon 1993;Gili and Hughes 1995;Bouillon et al 2006). They are particularly abundant in coastal rocky shores (Boero 1984;Gili and Hughes 1995;González-Duarte et al 2013a, b, 2016, where hydroids are usually present with a large number of colonies and species, including a high variety of forms that play diverse roles within their assemblages (Boero 1984;Boero and Fresi 1986;Gili and Hughes 1995;Piraino et al 2002). They exhibit a generalised behaviour with regard to substrate selection (Cornelius 1982;Genzano and Rodriguez 1998), and they also adapt well to a diversity of artificial structures including ship hulls of commercial vessels and recreational crafts (Floerl and Inglis 2005;Minchin et al 2006;Farrapeira et al 2011), buoys (Calder 1997;Kirkendale and Calder 2003), pilings (Migotto 1996;Galea 2008), fish cage nets (Guenther et al 2010;Bloecher et al 2013) or harbours and marinas (Floerl and Inglis 2005;Cangussu and Altvater 2010;Megina et al 2013Megina et al , 2016.…”

“…(Leloup 1935) is a recent invader in the Mediterranean Sea, first recorded in 1996 on the coast of Calabria (Ionian Sea, Italy) (Boero et al 1997). There are records from the Balearic Islands to South Adriatic Sea (Gravili et al 2008), however, this species was not collected in the Strait of Gibraltar or the Alboran Sea (the Atlantic entrance to the Mediterranean Sea) (Gravili et al 2008;González-Duarte et al 2013a, b, 2016, or the Levant Sea, (the first entrance for a Lessepsian immigrant) (Gravili et al 2008;Morri et al 2009). Thus, this species most probably arrived by maritime traffic, as suggested by several authors (Boero 2002;Gravili et al 2013).…”

The Cnidaria, Past, Present and Future

The study of the diversity and composition of marine communities is the first step in understanding the development of marine ecosystems. While some cnidarian populations are in decline, others invade new regions and habitats. The pressure of the human actions on the marine ecosystems has increased in the past decades. The artificial structures in marine environments, shipping, aquaculture, global warming and interoceanic canals have contributed to the dispersion, establishment and invasion of many places by alien species around the world, in some cases, with major ecological and socio-economic impacts. Some cnidarian species may serve as examples of the truly widespread reach of invasive species. Benthic phase of hydroids and anthozoans are common components of harbours and fouling communities and, probably, they have been transported on ship hulls. Ephyrae and hydromedusae are also frequently found in ballast water. Additionally, the global climatic change allows cnidarian of tropical affinity to extend their range into the temperate zones. The biological invasions and range extensions may cause local native biodiversity and economic losses. Only recently have these biological invasions attracted the attention of the scientific community. Though invasive alien cnidarians are recognized now as a global threat to biodiversity, and monitoring their presence and impacts is considered a prerequisite for marine environmental management and sustainable development, it seldom takes place even in the coastal regions most vulnerable to introductions

Inhabitant or visitor? Unexpected finding of Aglaophenia (Cnidaria, Hydrozoa) in Antarctic waters

Benthic hydrozoans are one of the most speciose and characteristic taxa from the Antarctic region, with a high number of endemic species, but diversity at the genus level is low and some families with world wide distribution are unrepresented. This is the case of the family Aglaopheniidae. A new species to science of the genus Aglaophenia Lamouroux has been found in the eastern end of the Weddell Sea, at depths of 65–116 m, within the material obtained by the German Antarctic expedition ANT XV/3. This finding constitutes a new record for the Weddell Sea fauna, the first evidence of the genus for the Polar Regions, and even the family Aglaopheniidae from Antarctic waters. The material has been accurately examined and described. Literature concerning the species of Aglaophenia from the sub-Antarctic and other close areas has been reviewed and, as a result, a checklist of 20 species, with their corresponding distribution, is given. The material examined does not agree with any of the species and therefore it is described as a new species. Some possible scenarios for the presence of an aglaopheniid in Antarctic waters are discussed (e.g. alien species, relict, global climate change, microhabitat).

Looking for long-term changes in hydroid assemblages (Cnidaria, Hydrozoa) in Alboran Sea (South-Western Mediterranean): a proposal of a monitoring point for the global warming

In the last 20-30 years, the temperature of the Mediterranean Sea has increased and global warming is allowing the establishment of tropical-affinity species into more temperate zones. Sessile communities are particularly useful as a baseline for ecological monitoring; however, a lack of historical data series exists for sessile marine organisms without commercial interest. Hydroids are ubiquitous components of the benthic sessile fauna on rocky shores and have been used as bio-indicators of environmental conditions. In this study on the benthic hydroid assemblages of the Chafarinas Islands (Alboran Sea, South-Western Mediterranean), we characterized the hydroid assemblages, identified the bathymetric gradients, and compared them with a previous study carried out in 1991. Hydroid assemblages showed a significant difference both between year and among depths. Furthermore, eight species not present in 1991 were found, including two possible new species and the tropical and subtropical species Sertularia marginata. Due to its strategic position at the entrance of the Mediterranean and the existence of previous data on hydroid assemblages, the Chafarinas Islands are proposed as a possible monitoring point for entrance of Atlantic tropical species into the Mediterranean Sea.
