(Received 3 August 2006, accepted 26 October 2006) Abstract – Freshwater Rhodophyta populations from high altitude streams (1,725-2,900 m a.s.l.) in the Mexican Volcanic Belt (MVB), between 18-19° N and 96-100° W, were investigated through the sampling of six stream segments from 1982 to 2006. Three species are documented, Batrachospermum gelatinosum,B. helminthosum and Sirodotia suecica, including their descriptions and physical and chemical water quality data from their environment. Batachospermum helminthosum and S. suecica are reported for the second time in MVB streams, with a first description in detail for the freshwater red algal flora from Mexico. All species were found in tropical climates (two seasons along a year, dry and rainy), at high altitudes (> 1,700 m a.s.l.), mild water temperatures (9.0-20.4°C), circumneutral (pH 6.0-8.2, bicarbonate as the dominant anion), and with a relative low ionic content (salinity 0.1 to 0.2 g l –1, specific conductance 77-270 µS cm –1). Two ecological groups of species were clearly distinguished on the basis of nutrient content. The first group, which includes B. -

During a survey in northeast India and east Nepal, six populations of the genus Sheathia were found and analyzed using molecular and morphological evidence. Phylogenetic analyses based on the rbcL gene sequences grouped all populations in a large clade including our S. arcuata specimens and others from several regions. Sheathia arcuata repre- sents a species complex with a high sequence divergence and several smaller clades. Samples from India and Nepal were grouped in three distinct clades with high support and representing new cryptic species: a clade formed by two samples from India, which was named Sheathia assamica sp. nov.; one sample from India and one from Nepal formed another clade, named Sheathia indonepalensis sp. nov.; two samples from Nepal grouped with sequences from Hawaii and In- donesia (only ‘Chantransia’ stages) and gametophytes from Taiwan, named Sheathia dispersa sp. -

Five orders, 6 families, 9 genera and 26 species were found. The most diverse genus was Batrachospermum which had 9 species, followed by Thorea, Bostrychia, Audouinella and Compsopogon each with 3 species and Nemalionopsis with 2 species. Genera represented as 1 species only were Sirodotia, Caloglossa and Compsopogonopsis. Most of the freshwater red algae were observed in water of clean to moderate quality. However, some species were in the clean water e.g. Batrachospermum boryanum Sirodot, B.gelatinosum (Linnaeus) de Candolle and B. macrosporum Montagne but some species were in moderate to polluted water e.g. Compsopogon coeruleus (Balbis) Montagne and Audouinella glomerata Jao. The latter species had a wide tolerance range i.e. -

Vis The phylogenetic affinities of five Australasian species of the freshwater red algal genus Batrachospermum were investigated using molecular and morphometric data. Specimens attributed to B. pseudogelatinosum, B. campyloclonum, B. kraftii, B. theaquum and B. bourrellyi, were collected from eastern Australia, Tasmania, New Caledonia and New Zealand. DNA sequence data from the plastid rbcL gene was used to infer interspecies relationships for all taxa. The mitochondrial cox2-3 gene spacer region was utilized to infer the intraspecific relationships among specimens of B. pseudogelatinosum, B. campyloclonum and B. bourrellyi. Two clades were resolved for B. pseudogelatinosum specimens in the rbcL, with B. bourrellyi placed equivocally as sister or within the clade. B. theaquum formed a separate clade in all analyses. -
Survey of Freshwater Red Algae from the Batrachospermales (Rhodophyta) in South Carolina
20192019 SOUTHEASTERNSoutheastern NaturalistNATURALIST 18(3):451–468Vol. 18, No. 3 A.M. Redmond, E.K. Hollingsworth, and M.L. Vis Survey of Freshwater Red Algae from the Batrachospermales (Rhodophyta) in South Carolina Alexis M. Redmond1, Emily K. Hollingsworth2, and Morgan L. Vis1,* Abstract - Freshwater red algae are important components of the algal flora in streams and rivers with high water quality. The order Batrachospermales is the most species- rich portion of the red algal taxa reported throughout North America. We investigated 30 stream segments in South Carolina for the presence of freshwater red algae classified within the Batrachospermales. We collected a total of 50 specimens representing 7 genera and 9 species. We documented Batrachospermum gelatinosum, B. turfosum, Kumanoa skujana, Montagnia australis, Sheathia americana, S. heterocortica, Sirodotia suecica, Tuomeya americana, and Virescentia viride-americana. We observed M. australis and T. americana from the greatest number of streams and in multiple years from the same site. We observed V. viride-americana in 3 streams; our specimens represent the only new record for the state. We generated DNA sequence data of the rbcL gene or gleaned it from the literature for 8 of the 9 taxa identified in the study and confirmed their morphologi- cal identification. We collected stream temperature, pH, and conductivity data from sites where we collected 6 of the taxa (Batrachospermum gelatinosum, B. turfosum, M. austra- lis, Sheathia americana, T. americana, and V. viride-americana). Our records were within previously reported ranges for these taxa, although water temperatures tended to be higher than those in previous reports. Present data for the diversity of Batrachospermales in South Carolina represent 64% of the generic/infrageneric and 20% of the species diversity known for North America. -

Elaya Perumal, R. Sundararaj* Department of Botany, Government Arts College for Men (Autonomous), Affiliated to University of Madras, Nandanam, Chennai 600035, India *Corresponding author, E-mail: [email protected] Abstract The Western Ghats are among the biodiversity hot spots of India, in which certain regions have been earlier studied for red algal diversity. Keeping this in mind, the Western Ghats and its associated areas were surveyed, which revealed the presence of many fresh water red algae species, including Kumanoa zeylanica from Coorg District of Karnataka State. The alga identified in the present study was earlier reported from the same state but 350 km (north) towards Belagavi, Karnataka. Morphological data of the current specimen showed more than 95% similarity with the species K. zeylanica in cluster analysis. Morphological characters like a distinct centrally inserted carposporophyte and contorted carpogonial branches allowed to categorize the alga under the genus Kumnaoa. Morphological and morphometric data on the carposporophyte, carposporangium, trichogyne, spermatia, and fascicle cells are very similar to that of the K. zeylanica reported by Balakrishnan and Chaugule in 1980. Key words: freshwater algae, morphology, red algae, taxonomy. Introduction & Chaugule was earlier described from the Jog falls of Karnataka state, India (Balakrishnan, Chaugule 1980b). Red algae (Rhodophyta), which are found outside marine This species was later renamed toKumanoa zeylanica (Skuja environments, are referred to as freshwater red algae. -

Sixteen species of freshwater red algae, belonging to eight genera (Audouinella, Bal- liopsis, Batrachospermum, Caloglossa, Compsopogon, Kumanoa, Sirodotia, and Thorea) were identified, which were all reported earlier for the country. Thorea clavata (Thoreaceae) was the most common species occurring in eight stream segments. Caloglossa beccarii sensu lato (Delesseriaceae) and Sirodotia huillensis Skuja (Batrachospermaceae) had the highest percent cover with up to 40% and 20% per stream segment, respectively. The water quality showed most sites to be unpolluted or ultra-oligotrophic to oligotrophic. Canonical Correspondence Analysis revealed some trends in occurrence of individual species with stream environmental variables: Batrachospermum sp.
