The Caulerpa racemosa invasion: a critical review.
Caulerpa racemosa var. cylindracea is a marine Chlorophyta introduced into the Mediterranean Sea from south-western Australia. Since 1990, it has been invading the Mediterranean Sea and the Canary Islands, raising ecological problems. Although this invasion event can be considered as one of the most serious in the history of species introduced into the Mediterranean Sea, C. racemosa has not tri...
متن کاملSeasonality of caulerpenyne content in native Caulerpa prolifera and invasive C. taxifolia and C. racemosa var. cylindracea in the western Mediterranean Sea
Fronds had higher mean caulerpenyne concentration than stolons in Caulerpa prolifera, C. taxifolia and C. racemosa. C. prolifera had higher mean caulerpenyne content w7.29"0.64% caulerpenyne/frond dry weight (DW)x than C. taxifolia (5.47"0.32% caulerpenyne/frond DW) and C. racemosa (0.43"0.07% caulerpenyne/frond DW). C. prolifera had reduced content from May to October in fronds, with no clear ...
متن کاملOn the identity and origin of the Mediterranean invasive Caulerpa racemosa (Caulerpales, Chlorophyta)
Recent morphological and genetic studies on the Caulerpa racemosa (Forsskål) J. Agardh complex have demonstrated that three taxa occur in the Mediterranean Sea. One of them, the ‘invasive variety’, provisionally regarded as close to C. racemosa var. occidentalis J. Agardh, is currently spreading spectacularly throughout the Mediterranean. On the basis of new morphological and molecular studies ...
متن کاملReciprocal Caulerpa Invasion: Mediterranean native Caulerpa ollivieri in the Bahamas supported by human nitrogen enrichment
The genus Caulerpa is known for its invasion of tropical, subtropical, and temperate coastal waters. Whereas the role of humans as vectors for the introduction of Caulerpa has been well documented, other anthropogenic factors that may mediate the success of an invasion are poorly understood. We provide evidence that a recent invasion of Caulerpa ollivieri into shallow Bahamian seagrass meadows ...
متن کاملAnti-herpetic activity of Caulerpa racemosa
BLACK Luffa sponge, derived from dried fruits of Luffa aegyptiaca Mill. (Sponge gourd, Hindi – Ghiya tori), could be a suitable matrix for tissue culture in aseptic liquid culture media. To test this, the response of aroid Philodendron ‘Xanadu’ Hort., an exquisite indoor-ornamental with its beautiful leaves and tangled aerial roots, was studied in vitro by Gangopadhyay and others. A study on in...
