PhD. Thesis, composite in English. University of South Bohemia, Faculty of Science, České Budějovice, Czech Republic, 110 pp, shortened version 30 pp. Annotation Since the human inclination to estimate and trace natural diversity, usable species definitions as well as taxonomical systems are required. As a consequence, the first proposed classification schemes assigned the filamentous and parenchymatous taxa to the green algal order Chaetophorales sensu Wille. The introduction of ultrastructural and molecular methods provided novel insight into algal evolution and generated taxonomic revisions based on phylogenetic inference. However, until now, the number of molecular phylogenetic studies focusing on the Chaetophorales s.s. is surprisingly low. To enhance knowledge about phylogenetic -
Chloroplast Phylogenomic Analysis of Chlorophyte Green Algae Identifies a Novel Lineage Sister to the Sphaeropleales (Chlorophyceae) Claude Lemieux*, Antony T
Lemieux et al. BMC Evolutionary Biology (2015) 15:264 DOI 10.1186/s12862-015-0544-5 RESEARCHARTICLE Open Access Chloroplast phylogenomic analysis of chlorophyte green algae identifies a novel lineage sister to the Sphaeropleales (Chlorophyceae) Claude Lemieux*, Antony T. Vincent, Aurélie Labarre, Christian Otis and Monique Turmel Abstract Background: The class Chlorophyceae (Chlorophyta) includes morphologically and ecologically diverse green algae. Most of the documented species belong to the clade formed by the Chlamydomonadales (also called Volvocales) and Sphaeropleales. Although studies based on the nuclear 18S rRNA gene or a few combined genes have shed light on the diversity and phylogenetic structure of the Chlamydomonadales, the positions of many of the monophyletic groups identified remain uncertain. Here, we used a chloroplast phylogenomic approach to delineate the relationships among these lineages. Results: To generate the analyzed amino acid and nucleotide data sets, we sequenced the chloroplast DNAs (cpDNAs) of 24 chlorophycean taxa; these included representatives from 16 of the 21 primary clades previously recognized in the Chlamydomonadales, two taxa from a coccoid lineage (Jenufa) that was suspected to be sister to the Golenkiniaceae, and two sphaeroplealeans. Using Bayesian and/or maximum likelihood inference methods, we analyzed an amino acid data set that was assembled from 69 cpDNA-encoded proteins of 73 core chlorophyte (including 33 chlorophyceans), as well as two nucleotide data sets that were generated from the 69 genes coding for these proteins and 29 RNA-coding genes. The protein and gene phylogenies were congruent and robustly resolved the branching order of most of the investigated lineages. Within the Chlamydomonadales, 22 taxa formed an assemblage of five major clades/lineages. -

Lokhorst Rijksherbarium, Schelpenkade6,2313 ZT Leiden Draparnaldia Bory is a genus of branched filamentous green algae which em- braces about 20 species. Its distributional pattern includes stable to ephemeral fresh water habitats including acid or alkaline conditions. It is sensitive to pollu- to be for the of natural fresh tion, hence it appears appropriate typification water systems. For example, in the saprobic system of Fjerdingstad (1964) Draparnaldia glomerata is employed as a biological indicator of oligosaprobic waters, while Draparnaldia plumosa defines water of katharobic status. Based ultrastructural with Stigeoclonium, on, e.g., grounds Draparnaldia together Fritschiella and Uronema constitute the very homogeneous Chaetophoraceae al. in (Barker & Lokhorst in press, Lokhorst et press). In its natural habitat, the alga demonstrates a conspicuous main axis con- cells from which alternate sisting of barrel-shaped or cylindrical opposite, or whorled fascicles of setiferous branchlets project (Prescott 1951). However, when this alga is brought into culture, its phenotypic plasticity is expressed by loss in to main rise to a gradual ability produce axes, thereby giving a Stigeoclo- nium-like growth habit (e.g., Carroll & Deason 1969; personal observations). Several experimental studies attempted to decipher the causes of this poly- morphism in Draparnaldia. Uspenskaja (1930) concluded that an increase of the nitrate level, both in natural environment and in culture, accounts for the morphological change in Draparnaldia. In additional studies, Suomalainen that an increase of both and C0 -concentration (1933) reported light intensity 2 promotes main axis development, the frequency ofbranching and the formation of setae in this alga. -

Shoreline Algae of Western Lake Erie1
THE OHIO JOURNAL OF SCIENCE Vol. 70 SEPTEMBER, 1970 ' No. 5 SHORELINE ALGAE OF WESTERN LAKE ERIE1 RACHEL COX DOWNING2 Graduate Studies in Botany, The Ohio State University, Columbus, Ohio J/.3210 ABSTRACT The algae of western Lake Erie have been extensively studied for more than 70 years, but, until the present study by the author, conducted between April and October, 1967, almost nothing was known of the shoreline as a specific algal habitat. A total of 61 taxa were identified from the shorelines. The importance of this habitat is very clear from the results of this study, for, of the 61 taxa found, 39 are new records for western Lake Erie, and one, Arnoldiella conchophila Miller, appears to be a new United States record, having been previously reported only from central Russia. Western Lake Erie has been the site of extensive phycological research since 1898. After some 70 years of algal study, it would be reasonable to assume that all the various habitats would have been thoroughly studied and reported on, but when reports of research were compiled by Dr. Clarence E. Taft for a taxonomic summary, it became apparent that the shoreline had been neglected. Considerable information on the algae of the ponds, marshes, swamps, quarry ponds, open lake, inlets, ditches, and canals has been reported on by individuals and by agencies doing research, and by the algae classes at the Franz Theodore Stone Laboratory, Put-in-Bay, Ohio. Papers containing this information are by Jennings (1900), Pieters (1902), Snow (1902), Stehle (1923), Tiffany and Ahlstrom (1931), Ahlstrom and Tiffany (1934), Tiffany (1934 and 1937), Chandler (1940), Taft (1940 and 1942), Daily (1942 and 1945), Taft (1945 and 1946), Wood (1947), Curl (1951), McMilliam (1951), Verduin (1952), Wright (1955), Normanden and Taft (1959), Taft (1964a and 1964b), and Taft and Kishler (1968). -
The Occurrence of the Green Alga Prododerma Viride (Chlorophyceae) in Michigan
2017 THE GREAT LAKES BOTANIST 201 THE OCCURRENCE OF THE GREEN ALGA PRODODERMA VIRIDE (CHLOROPHYCEAE) IN MICHIGAN Daniel E. Wujek Department of Biology Central Michigan University Mt. Pleasant, MI 48859 ABSTRACT The epiphytic branched filamentous green alga Protoderma viride is reported from Michigan for the first time. An alga occurring worldwide, its only other report for the Great Lakes region is from Wisconsin. Using light microscopy it was observed from numerous strata from one Upper Peninsula site and several Lower Peninsula locations. INTRODUCTION The widely occurring green algal genus Protoderma K¸tzing has been re - ported from all seven continents and the Pacific Ocean islands (Burova et al. 2011, Guiry 2016). Of the nine species currently accepted taxonomically (six freshwater, three marine; Guiry 2016) only the species Protoderma viride K¸tzing has been reported from as many as six continents, though it is not known from Antarctica. Considering that it is the most widely distributed species of Protoderma (Guiry 2016), it is surprising that it has never been reported from Michigan. The only previous record of its occurrence from the Great Lakes re - gion is from Wisconsin (Prescott 1962). METHODS AND MATERIALS More than 30 samples containing Protoderma viride were collected throughout Michigan over a 32-years period (summer months 1971ñ2002). The environments from which the collections were taken ranged from lotic to lentic and from shaded to bright light. Protoderma viride K¸tzing was found variously on rocks, pebbles, and macrophytes (e.g., Potamogeton spp., Sagittaria spp., Typha latifolia, and Valisneria americana) or other filamentous algae (e.g., Chaetophora spp., Cladophora glomerata, Oedogonium spp., and Rhizoclonium). -

Non-Marine Algae of Australia: 5. Macroscopic Chaetophoraceae (Chaetophorales, Chlorophyta)
613 Non-marine algae of Australia: 5. Macroscopic Chaetophoraceae (Chaetophorales, Chlorophyta) Stephen Skinner and Timothy J. Entwisle Abstract Skinner, S. and Entwisle, T.J. (Botanic Gardens Trust Sydney, Mrs Macquaries Road, Sydney NSW 2000, Australia. Email: [email protected]) 2004. Non-marine algae of Australia: 5. Macroscopic Chaetophoraceae (Chaetophorales, Chlorophyta). Telopea 10(2): 613–633. Five macroalgal genera in the Chaetophoraceae (Chaetophorales, Chlorophyceae) are documented from Australia: Draparnaldiopsis salishensis is newly recorded; Uronema confevicolum is confirmed and its distribution extended, similarly for Chaetophora attenuata, C. pisiformis and C. elegans. The distributions of Draparnaldia mutabilis and Stigeoclonium tenue and S. farctum are extended, building on the previous studies by Entwisle (1989a, 1989b) in Victoria. Stigeoclonium helveticum is shown to be widespread in New South Wales. Introduction We present here a floristic revision of freshwater macroalgae from the family Chaetophoraceae. Our treatment is based on new collections, mostly from N.S.W., and available herbarium specimens. Quite a number of these species are widely distributed algae, conspicuous as the main species in algal tufts attached to rocks, snags and aquatic vegetation, in streams and standing water. They are frequently included, unvouchered, in species lists e.g. May & Powell (1986), Grimes (1988). Previous workers have identified these algae most commonly by reference to descriptions in floras of other regions of the world (e.g. Prescott 1951). As often happens in surveys and monitoring of water bodies, the dilemma faced by the scientist or technician has been to find a ‘name’, fit it to a ‘shape’, and then be consistent in the application of that ‘name’. -

Abstract Physico chemical studies of two fresh water ponds at Gorakhpur showed that Chaetophorales were almost absent in polluted water. Stigeoclonium nanum flourished well only in polluted water and appeared as biological indicator of water pollution. Stigeoclonium farctum and Pseudulvella americana var. indica were found in both polluted and less polluted ponds indicating that they were pollution tolerant.
