“…This study provides an inventory of the bryozoan assemblages from the whole coastal zone of Lebanon collected in the context of field surveys spread over several years. The studied collection has first given rise to several taxonomic revisions (Harmelin, 2014 a-b;Harmelin et al, 2007Harmelin et al, , 2009Harmelin et al, , 2011Harmelin et al, , 2012. These previous works provided the basis for clarifying several taxonomic uncertainties, describing new taxa and highlighting the occurrence of many non-indigenous species never previously recorded in the Mediterranean.…”

“…The geographical range of the NIB species recorded in Lebanon was compiled from recent relevant sources and categorized according to the biogeographical classification proposed by Spalding et al (2007), with slight modifications (Table 6). As noted in previous descriptions of the Lebanese NIB species (Harmelin et al, 2007(Harmelin et al, , 2009(Harmelin et al, , 2011(Harmelin et al, , 2012Harmelin, 2014b), knowledge of the actual range of many of them is hampered by taxonomic uncertainties involving sibling species. However, some clear trends can be evidenced.…”

Because of its location in the warmest corner of the Mediterranean, its proximity to the northern entrance of the Suez Canal, i.e. the gateway for massive exotic biota introduction into the Mediterranean, the occurrence of high shipping activity and strong human pressure, the Lebanese coastal zone is an area that is exceptionally well-suited for investigating the effects of these extreme conditions on Mediterranean biodiversity. Bryozoans, which are among the main components of sessile communities, reflect dramatically the impact of these particular conditions. Their assemblages, sampled by diving along the whole coast of Lebanon during a pluriannual programme, mainly between 1999 and 2003, consist of 93 species (12 Cyclostomata, 2 Ctenostomata, 79 Cheilostomata). The native part of this bryozoan fauna exhibits low diversity, with an unexpected absence of many taxa, from family to species level, which are very common in the rest of the Mediterranean. It is also characterized by a high proportion of endemic species, in contrast with the general eastward trend of decreasing endemicity observed in the Mediterranean, and by the strong presence of 'southern' thermophilic species. With 27 non-indigenous species, xenodiversity is exceptionally high, particularly in the cheilostome pool (26 species), but was likely undersampled. Moreover, one may assume that new non-indigenous bryozoans (NIB) are now established along the Levantine coasts. This trend is expected to increase in the near future with the intensification of surface water warming and boost of shipping activity and propagule flux generated by the expansion of the Suez Canal.

“…Additionally, a rich collection of benthic samples from coastal habitats in Lebanon has provided a basis for focusing in particular on alien bryozoans (Bitar & Kouli-Bitar 2001;Harmelin et al 2007Harmelin et al , 2009Harmelin et al , 2011Harmelin et al , 2012, leading to the identification of 10 non-indigenous and one cryptogenic species. The present study deals with 13 non-indigenous and one cryptogenic cheilostome species, in eight families, not already recorded from the same collection.…”

The Levant Basin (SE Mediterranean) is the most exposed to the introduction of non-indigenous species. The current assessment of exotic bryozoans present along the coast of Lebanon has been completed by the recording of fourteen cheilostome species (one cryptogenic) collected by diving in 17 localities (2-42 m). This set of exotic bryozoans comprises ten genera, including four (Akatopora Davis, 1934, Drepanophora Harmer, 1957, Mucropetraliella Stach, 1936 and Predanophora Tilbrook, 2006) not previously reported in the Mediterranean, while Celleporaria is the most successful extra-Mediterranean genus with four species in the survey collection. A new Celleporina species, C. bitari n. sp., also collected in the Red Sea, is described. Although lessepsian migration through the Suez Canal is the main pathway for exotic bryozoans in this region, the geographic origin of some species suggests that shipping through Gibraltar Strait is also responsible to a large extent.

“…This widely distributed species was revised by Harmelin et al (2012) who noted its preference for gastropod shells. The two colonies collected in Malaysia, one from Langkawi and the other from Penang, are both on gastropod shells, though not a living gastropod in the case of the Langkawi specimen, which encrusts an interior surface.…”

Abstract. Twenty-three species of cheilostome bryozoans are described from the Malaysian islands of Penang and Langkawi based on a brief reconnaisance survey of shore localities. These are the first bryozoans to be formally described from either island and they demonstrate the potential for further research on these neglected suspension feeders. Of the 23 species recorded, 12 are anascans, half of which are malacostegines, and 11 are ascophorans. The new combinations Acanthodesia falsitenuis (Liu, 1992), A. perambulata (Louis &Menon, 2009) and A. irregulata (Liu, 1992) are introduced. Most of the species recorded are widespread in the Indo-Pacific, and some are apparently globally distributed in the tropics and subtropics, including the invasive fouling species Bugula neritina, Hippoporina indica and Schizoporella japonica, as well as the coral reef associates Cranosina coronata and Hippopodina feegeensis. Plastic debris and glass bottles were encrusted by Jellyella eburnea, a coloniser of floating biological and man-made objects that is becoming widespread in the tropics and subtropics of the world's oceans.
