It is fundamental to increase the commitment of the scientific community to primarily classical taxonomy coupled with ecofisiological and molecular studies in phylogenesis, still crucial and essential to reveal the desmid flora in Brazil and which should be constantly stimulated.Keywords:desmid flora, desmidiales, microalgae, neotropical region, checklist The phytotelmata flora was represented by sixteen taxa belonging to the genera: Actinotaenium (1), Cosmarium (9), Euastrum (2), Micrasterias (2) Pleurotaenium (1), Staurastrum (1). Their cells show a beautiful symmetry, which distinguishes them from all other algal groups. A Contribution to the Freshwater Algæ of West Ireland. Four taxa (Actinotaenium riethii, Closterium pseudocostatum, Cosmarium discrepans and C. hostensiense) are newly described and the name of one taxon (Cosmarium lenzenwegeri) is recombined. Volumes on Euglenophyceae and part of the Bacillariophyceae are already ready (contribution of some colleague taxonomists), waiting for me to format for publication. The qualitative analysis was done by optical microscopic on non-permanent slides. The Teiling, Closterium navicula (Brébisson) Lütkemuller var. , 2012 ). With the phenomenal increase in urban population and industrial growth during the past few decades, some of the major problems of a basic nature confronting mankind are those of quantity and quality of food, feed, drinking water, disposal of sewage and industrial wastes, and of proper conservation of soils and waters. 1 in Stamenković et al.

You can request the full-text of this article directly from the authors on ResearchGate. In addition, an evaluation of the morphological characteristics of zygospores can assist in separating species that overlap morphologically (Brook 1981;Neustupa & Skaloud 2007;Neustupa & Stastný 2006). The samples analyses allowed the description of 31 taxa distributed among 10 genera. Considering some ten desmid floral regions as distinguished in the beginning of this century, Indo- Malaysia/Northern Australia, tropical America, and equatorial Africa come to the fore as most pronounced. bromeliads exhibited little similarity in species composition, with only one species (Phacus polytrophos) occurring in all four species. Cosmarium pyramidatum var. This work presents the first report of algae in microhabitat of bromeliads in Thailand. Email This BlogThis! Cosmarium quinarium f. irregulare . nov. is described from samples collected from a bromeliad tank (phytotelmata) in a “restinga” area located at Salvador, Bahia State, northeast Brazil. of the biological species concept is seriously hampered by lack of sexual reproduction in many species. elongatum and Euastrum octogibbosum). A single nucleus is found in the isthmus region. Our results contribute to the knowledge of microalga communities of bromeliad phytotelmata in Brazil with regard to species richness and composition, as well as significant environmental characteristics. The cells posses a three layered transversely segmented walls with vertical poles arranged in a definite pattern. Genus: Cosmarium. Nestes ambientes, foram coletadas ao acaso vinte e cinco amostras através do Estado do Rio de Janeiro. Algae from the phytotelms of two species of bromeliads, both exposed to the sunlight and to the shade, were sampled, and a number of abiotic variables were measured (temperature, pH, and electric conductivity of water). (1986) Flora of New Zealand: Freshwater algae, Chlorophyta, Desmids. In addition, the morphology of Cosmarium cataractarum and C. cinctutum is described in greater detail, confirming their status as independent species. http://www.algaebase.org (accessed 3 September 2015). Do total, nove táxons (50%) são citados pela primeira vez para o Estado do Paraná: C. denticulatum Borge var. We describe gamete fusion type in S. gracile and establish that meiosis occurs in early stages of zygospore formation, characterising the morphology of all stages until germination.

(Floristic composition of Desmidiales (except Cosmarium) on a Brazilian subtropical lake). , 1992 ). The geographic distribution of some well-recognizable Among the few published studies are those of Gebühr et al. Cosmarium is a uni-cellular fresh water desmids occurring in ponds, rich in organic decaying matter, along with other free-floating algae. Arguments for a tropical origin of the desmids as an algal group are adduced. Which remains join together by a connecting zone called isthmus. With … (2011) Desmídias perifíticas de cinco lagoas do Distrito Federal, Brasil: I -Gênero Studies of the microalgae in bromeliad phytotelmata in northeastern Brazil revealed the occurrence of some interesting desmids-including new and rare taxa, besides new records for South America. Available from: Key words: artificial lake, desmids, Paraná. The taxonomic survey of the desmids (Zygnemaphyceae) of the rivers in the area of the Hydroelectric Power Plant in Salto Caxias, in the State of Paraná, Brazil, was carried out by monthly collections at 15 sampling stations, from February, 1997 to February, 1998. Seven contributions are already published. Although the conditions in these water tanks are challenging, the occurrence of different algae and cyanobacteria in such specific ecological niches may suggest wide adaptive abilities among these organisms.
