“…Both algae are tolerant of nutrients and sometimes increase their coverage under eutrophic conditions (Gennaro & Piazzi, 2011), but they are characterized by completely different thallus morphology. Laurencia chondrioides is a long-established introduction in the Mediterranean Sea (Boisset et al, 1998) but it is considered a non-invasive species (Boudouresque & Verlaque, 2002). In the study area, it may be considered naturalized in deep subtidal rocky habitats (Piazzi & Balata, 2011).…”

The aim of this study was to evaluate whether the success of invasive Caulerpa cylindracea (Caulerpa racemosa var. cylindracea) in Mediterranean habitats may be linked to particular nutritional requirements and/or nutrient accumulation/reallocation dynamics within the algal thallus. To this end, a manipulative field experiment was carried out transplanting C. cylindracea and supplying nutrients to subtidal rocky macroalgal assemblages. Morphological features of C. cylindracea were measured, while percentage cover and tissue nitrogen, carbon and phosphorus were determined for C. cylindracea and two co-occurring species (the introduced Laurencia chondrioides and native Flabellia petiolata) in nutrient-enriched and unenriched conditions. Growth of C. cylindracea was greater in the nutrient-enriched plots while no effect of nutrient enrichment was detected in co-occurring macroalgae. A particularly high requirement for nitrogen has been observed in C. cylindracea, but without severe N-limitation, while a general nutritional state of P-limitation was detected in both invasive and co-occurring macroalgae. The absence of inhibition in hypertrophic conditions and under high levels of ammonia together with a strong uptake and quick reallocation of nutrients within the coenocytic thallus probably represent the main advantages over the other co-occurring species which could explain part of the success of C. cylindracea in the Mediterranean Sea.

“…chondrioides Børgesen (Fig. 11) Described from the Caribbean Sea, L. chondrioides was first recorded in the Mediterranean Sea from the Balearic Islands, the Aeolian Islands and from Lachea Island (Boisset et al, 1998). Subsequently, the species was reported throughout the Mediterranean Sea, without mention of any pullulation, until late October 2007, when discovered large quantities of a species of Laurencia, referred to as L. chondrioides, in the algal drift on the shore at Haifa.…”

“…Both its recent arrival and its invasive behaviour argue in favour of an introduction on the Levantine coasts. However, the natural presence of L. chondrioides in the Canary Islands, where many Mediterranean taxa are native, makes a recent introduction of the species into the Mediterranean Sea unlikely (Boisset et al, 1998). Consequently, the origin and the identity of this invasive Laurencia should be confirmed by molecular study because the possibility of an introduction through the Suez Canal of another Indo-Pacific species must be considered.…”

The marine macroflora introduced into Lebanon was studied through an analysis of historical data and field studies carried out since 1991. A total of 29 introduced species have been listed: 3 Chromobionta, 13 Rhodobionta, 12 Chlorobionta and 1 Streptobionta. Among them, Caulerpa taxifolia var. distichophylla, Spatoglossum variabile and Womersleyella setacea are recorded for the first time from Lebanon. Among them, Asparagopsis taxiformis, C. taxifolia var. distichophylla, Cladophora patentiramea, Codium arabicum, Codium parvulum, Galaxaura rugosa, Halophila stipulacea, Hypnea cornuta, Laurencia cf. chondrioides, Lophocladia lallemandii, Stypopodium schimperi, Ulva lactuca and Womersleyella setacea are potentially invasive species, and several of them already occupy extensive stretches of the Lebanese coast. The distribution of species on the Levantine coast, their dynamics and the current status of their populations are discussed.

“…Laurencia chondrioides Børgesen described from the Danish West Indies, Caribbean Sea, is similar to L. venusta in overall appearance and by their anatomical coincidence (Boisset et al 1998). However, the species are distinguished by the branching pattern, which is verticillate in L. venusta and alternate or irregular in Laurencia chondrioides.…”
