Molecular analyses elucidate the taxonomy of fully corticated, nonspiny species of Ceramium (Ceramiaceae, Rhodophyta) in the British Isles

Rapid Assessment Surveys of Fouling and Introduced Seaweeds in the Northwest Atlantic

“…fragile occurs by motile unicells (?parthenogenetic female gametes) or vegetative fragments (Fralick andMathieson 1972, 1973;Guiry and Guiry 2007;Silva 1955); the latter are bouyant and can aid in localized dispersal (Carlton and Scanlon 1985). As noted by Husa and Sjotun (2006) many introduced seaweeds can reproduce asexually by vegetative propagation, aiding in their rapid dispersal (Bjaerke and Rueness 2004;Boudouresque and Verlaque 2002;Maggs and Stegenga 1999;Nyberg and Wallentinus 2005;Schaffelke and Deane 2005).…”

“…PRESENT NORTHWEST ATLANTIC DISTRIBUTION: Newfoundland to GA, growing in sheltered to somewhat exposed habitats (Bird and McLachlan 1992;Maggs and Hommersand 1993;South and Tittley 1986). …”

Ceramium cormacii sp. nov. (Ceramiaceae, Rhodophyta), a new Mediterranean species epizoic on loggerhead sea turtles (Caretta caretta)

“…Generic and specifi c taxonomies remain confusing as plants are delicate, diminutive and morphologically variable (Boo and Lee 1994 ); the genus is not yet satisfactorily circumscribed (Maggs et al 2002 ). Reinboldiella De Toni, Centroceras K ü tzing and Corallophila Weber van Bosse have been segregated from Ceramium ; more recently, on the basis of comparative morphology and phylogenetic analyses of rbc L and LSU rDNA sequence data, the new genus Gayliella was proposed to accommodate the Ceramium fl accidum complex (Cho et al 2008 ).…”
