A Taxonomic Review of Hawaiian Gelidiales ( Rhodophyta )
The present study reviews most collections of Gelidiales known from Hawaii. Three genera, each one including four species, are recognized among nearly 350 specimens examined. The genus Gelidiefla is represented in Hawaii by G. acerosa (Forsskal) Feldmann et Hamel, G. adnata Dawson, G. machrisiana Dawson, and G. myrioclada B0rgesen. The genus Gelidium includes G. crinale (Turner) Lamouroux, G. p...
متن کاملResolving cryptic species of Bossiella (Corallinales, Rhodophyta) using contemporary and historical DNA.
PREMISE OF THE STUDY Phenotypic plasticity and convergent evolution have long complicated traditional morphological taxonomy. Fortunately, DNA sequences provide an additional basis for comparison, independent of morphology. Most importantly, by obtaining DNA sequences from historical type specimens, we are now able to unequivocally match species names to genetic groups, often with surprising re...
متن کاملChiharaea and Yamadaia (corallinales, Rhodophyta) Represent Reduced and Recently Derived Articulated Coralline Morphologies(1).
Phycologists have hypothesized that the diminutive fronds produced by species in the genera Chiharaea and Yamadaia, which are composed of comparatively few genicula and intergenicula, represent morphological intermediates in the evolution of articulated corallines from crustose ancestors. We test this "intermediate frond hypothesis" by comparing rbcL sequences from the generitype species Chihar...
متن کاملCrusticorallina gen. nov., a nongeniculate genus in the subfamily Corallinoideae (Corallinales, Rhodophyta).
Molecular phylogenetic analyses of 18S rDNA (SSU) gene sequences confirm the placement of Crusticorallina gen. nov. in Corallinoideae, the first nongeniculate genus in an otherwise geniculate subfamily. Crusticorallina is distinguished from all other coralline genera by the following suite of morpho-anatomical characters: (i) sunken, uniporate gametangial and bi/tetrasporangial conceptacles, (i...
متن کاملCorallina and Ellisolandia (Corallinales, Rhodophyta) photophysiology over daylight tidal emersion: interactions with irradiance, temperature and carbonate chemistry
The photophysiology of three geniculate coralline algal species (Corallina officinalis, C. caespitosa and Ellisolandia elongata) was determined in intertidal rock pools in the south-west UK at Combe Martin (51°12'31N 4°2'19W) and Heybrook Bay (50°31'66N 4°11'41W), at the start, middle and end of summer (September 1 and 2) and winter (February 9 and 10) daylight tidal emersion periods, in relati...
