Norwida 4, 20-061 Lublin, Poland e-mail: [email protected] (Received: April 7, 2003. Accepted: July 18, 2003) ABSTRACT During studies of phytoplankton in Sumin Lake (£êczna-W³odawa Lakeland), conducted from May till Sep- tember 2001 and 2002, 15 taxa of the genus Pediastrum (Hydrodictyaceae, Sphaeropleales) were found. Among them there were common species as Pediastrum boryanum, P. duplex, P. tetras and P. simplex, but also rare spe- cies as P. integrum or P. kawraiskyi. An especially interesting species was P. orientale, the taxon that until now has not been noted in phytoplankton of Polish water bodies. The paper gives descriptions of the genus Pediastrum coenobia and physico-chemical conditions of the habitat. The original documentation of Pediastrum taxa is added.

BIODIVERSITY OF MICROSCOPIC GREEN ALGAE FROM DESERT SOIL CRUSTS Victoria Williamson Faculty Supervisor: Karolina Fučíková Natural Science Department A Thesis Submitted to Fulfill the Requirements of the Honors Program at Assumption College Spring 2020 Williamson 1 Abstract In the desert ecosystem, the ground is covered with soil crusts. Several organisms exist here, such as cyanobacteria, lichens, mosses, fungi, bacteria, and green algae. This most superficial layer of the soil contains several primary producers of the food web in this ecosystem, which stabilize the soil, facilitate plant growth, protect from water and wind erosion, and provide water filtration and nitrogen fixation. Researching the biodiversity of green algae in the soil crusts can provide more context about the importance of the soil crusts. Little is known about the species of green algae that live there, and through DNA-based phylogeny and microscopy, more can be understood. In this study, DNA was extracted from algal cultures newly isolated from desert soil crusts in New Mexico and California. -

Evolutionary Relationships Between the Varieties of Green Algae Pediastrum Boryanum and P
170 Fottea, Olomouc, 18(2): 170–188, 2018 DOI: 10.5507/fot.2018.004 Evolutionary relationships between the varieties of green algae Pediastrum boryanum and P. duplex s.l. (Chlorophyceae, Hydrodictyaceae) Joanna Lenarczyk* & Marta Saługa W. Szafer Institute of Botany, Polish Academy of Sciences, Lubicz 46, 31–512 Kraków, Poland; *Corresponding author e–mail: [email protected] Abstract: The infraspecific relationships of the two most variable species,Pediastrum boryanum and P. duplex s.l. identified on the basis of morphological criteria, have been poorly studied so far. The present study focused on 12 original strains isolated from Polish water bodies and 29 strains from the GenBank database, which represent P. boryanum, P. duplex s.l. varieties and other morphologically similar taxa, against the background of 14 other strains of the family Hydrodictyaceae. In order to estimate the level of congruence between the phylogeny and the classical taxonomic system based on morphological criteria, the strains of P. boryanum and P. duplex s.l., and other morphologically similar taxa were subjected to parallel phylogenetic analyses applying Bayesian and Maximum Likelihood methods to combined molecular data (26S rDNA and rbcL cpDNA) and morphological analyses based on light and scanning electron microscopy, and iconographic documentation of almost all strains published elsewhere. The gene topologies revealed many discrepancies in the morphological features used to delimit the analysed taxa. The polyphyly of both P. boryanum and P. duplex s.l. was confirmed. Pseudopediastrum boryanum var. cornutum (formerly P. boryanum var. cornutum) formed a well supported monophyletic clade, whereas other varieties, including var. boryanum, brevicorne and longicorne, proved to be complex taxa. -

Gene sequence alignments are available in TreeBase under study number 16246. Abstract The majority of our knowledge about mitochondrial genomes of Viridiplantae comes from land plants, but much less is known about their green algal relatives. In the green algal order Sphaeropleales (Chlorophyta), only one representative mitochondrial genome is currently available—that of Acutodesmus obliquus. Our study adds nine completely sequenced and three partially sequenced mi- tochondrial genomes spanning the phylogenetic diversity of Sphaeropleales. We show not only a size range of 25–53 kb and variation in intron content (0–11) and gene order but also conservation of 13 core respiratory genes and fragmented ribosomal RNA genes. We also report an unusual case of gene arrangement convergence in Neochloris aquatica, where the two rns fragments were secondarily placed in close proximity. Finally, we report the unprecedented usage of UCG as stop codon in Pseudomuriella schumacherensis.In addition, phylogenetic analyses of the mitochondrial protein-coding genes yield a fully resolved, well-supported phylogeny, showing promise for addressing systematic challenges in green algae. -
Introduction
Chapter 1 INTRODUCTION 1.1 ALGAL ORIGIN AND DIVERSITY For millennia, aquatic environment has been a dwelling place for many simple life forms to complex biological forms of higher order. Algae are one such aquatic forms which have vast resources of biochemicals that have not yet been explored properly. They are a diverse group of organisms some time ago thought to fit into a single class of plants. In the beginning, algae were considered to be simple plants lacking leaf, stem, root and reproductive systems of Higher Plants such as mosses, ferns, conifers and flowering plants. However, it was realized that some of them have animal like characteristics so they were incorporated in both the plant and animal kingdoms. Thus, algae are considered as oxygen producing, photosynthetic organisms that include macroalgae, mainly seaweeds and a diverse group of microorganisms known as microalgae. This book focuses mainly on microalgae. They are photosynthetic and can absorb the sun’s energy to digest water and CO2, releasing the precious atmospheric oxygen that allows the entire food chain to sprout and flourish in all its rich diversity. Microalgae have many special features, which make them an interesting class of organisms. Many freshwater algae are microscopic in nature. They vary in size ranging from a smallest cell diameter of 1000 mm to largest algal seaweed of 60 m in height. Microalgae are very colourful. They exhibit different colours such as green, brown and red. In general, microalgae have shade between and mixtures of these colors. Most of them can make their own food materials through photosynthesis by using sunlight, water and carbon dioxide. -

(2005): Changes in shape of the coenobial cells of an experimental strain of Pediastrum duplex var. duplex (Chlorophyta) reared at different pH. – Preslia, Praha, 77: 439–452. The changes in shape of the marginal coenobial cells in an experimentally cultured population of Pediastrum duplex Meyen var. duplex were investigated. The methods of landmark-based geomet- ric morphometrics, including sliding landmarks registration, were used. The populations were cul- tured at 11 different pH levels and the changes in shape related to pH were studied using multivariate regression. The results of relative warps analysis revealed that morphological trends are related to both size and pH. The potential application of the results of this geometric morphometrical analysis of Pediastrum for biomonitoring and palaeoecological studies are discussed.

Seasonal Variation in Algal Diversity and Productivity in Dachi Lake, Meghalaya
J. Algal Biomass Utln. 2018, 9(2): 9-24 Seasonal variation in algal diversity and productivity in Dachi lake eISSN: 2229 – 6905 Seasonal variation in algal diversity and productivity in Dachi lake, Meghalaya Pranita Hajong* and Papiya Ramanujam Algal Ecology Laboratory, Centre for Advanced Studies in Botany, North Eastern Hill University, Shillong, Meghalaya 793022, India *e-mail: [email protected] Abstract: Seasonal variation in algal diversity and productivity in Dachi lake was carried out from September 2015 to August 2016. Dachi lake is well known tourist spot in West Garo Hills. It is maintained by Soil and Water Conservation Department of Meghalaya. A total of 176 algal species belonging to 8 classes were recorded. A distinct seasonal variation in diversity was observed, which varied from 1.45 in summer to 3.1 in spring. Primary productivity was also maximum in spring (3.07 gC/m3/h) and was minimum in summer (0.97gC/m3/h). Seasonal variation in physico-chemical parameters was observed and the nutrients concentration was recorded within the permissible limit of World Health Organization standard. Pearson’s correlation analysis revealed that primary productivity positively correlated with pH, transparency and dissolved oxygen and negatively correlated with turbidity and nutrients. It can be concluded that productivity in Dachi lake is driven by transparency of the water which allowed light to penetrate and promote productivity. Diversity indicated the clean status of the lake. The lake is maintained well by the Soil and Water Conservation Department hence pollution caused by the tourist was negligible. The changes in physico-chemical parameters, algal community and primary productivity are mainly due to seasonal changes.
