Abstract This study tested potential chemical defense of the green seaweed Avrainvillea elliottii against grazing by the sea urchin Lytechinus variegatus. We examined intraspecific variation of defensive chemicals in different parts of the thallus (margin, blade and stipe).

SUMMARYSome introduced species compete directly with native species for resources and their spread can alter communities, while others do not proliferate and remain benign. This study compares community structure and diversity in adjacent areas dominated by the introduced alga Avrainvillea sp. or native algal species on a hard substrate reef.

Three species of marine algae are reported from the Bermuda islands for the first time, Avrainvillea sylvearleae D. S. Littler et Littler, Discosporangium mesarthrocarpum (Menegh.) Hauck, and Peyssonnelia valentinii Yonesh. et Boudour. The presence of Avrainvillea sylvearleae in Bermuda prompted a taxonomic reinvestigation of North Carolina specimens ...

Abstract Macrosegregation of nucleoli, a feature generally associated with a temporarily reduced rate of ribosomal RNA synthesis, occurs in three genera of siphonous green algae, Avrainvillea, Cladocephalus and Blastophysa. This condition persists throughout the vegetative phase of the life history and, thus, may indicate a peculiar rRNA cycle. Nuclear

ABSTRACTThe relative rates of sexual versus asexual reproduction influence the partitioning of genetic diversity within and among populations. During range expansions, uniparental reproduction often facilitates colonization and establishment. The arrival of the green algaAvrainvillea laceratahas caused shifts in habitat structure and community ...
