However, taxonomic and floristic studies on algae in the Euphrates basin are still scarce. This study contributes new information to the knowledge of the Turkish freshwater algal flora. Phytoplankton samples were collected from the Tatar Dam Reservoir in the Euphrates Basin between January 2016 and December 2016. Two taxa were recorded for first time and 14 rare taxa for the freshwater algae of Turkey were identified in this study. The new records belong to the phylum Bacillariophyta, whereas taxa considered as rare belong to the phyla Chlorophyta, Cyanobacteria, Rhodophyta, Charophyta, Euglenophyta, and Bacillariophyta. The morphology and taxonomy of these taxa are briefly described in the paper and original light microscopy illustrations are provided.

ABSTRACT BISHOP, WEST MICHAEL. a Risk
ABSTRACT BISHOP, WEST MICHAEL. A Risk-based Decision Information System for Selecting an Algal Management Program. (Under the direction of Dr. Robert J. Richardson). Freshwater resources are a vital component needed to support numerous human activities. Climate change, water use dynamics, and eutrophication have synergistically promoted nuisance and noxious algal blooms throughout the world. The increasing distribution, duration, and intensity of algal blooms has created unprecedented concerns over safety and usability of freshwater. Some of the largest blooms ever documented have occurred in the recent past. This dissertation is designed to provide a framework to assist in 1) understanding risks associated with nuisance algal infestations and 2) comparatively assessing the efficacy, costs, and collateral risks of different management approaches. The management decision framework consists of characterizing dimensions of the problem, identifying management objectives, and applying research to create a strategic management approach that incorporates risks of no action as well as risks associated with different management strategies. By considering information from the research chapters included herein, an accurate assessment of risks can be conducted in terms of the effectiveness and ecological integrity of management approaches. This research should be used to make informed decisions regarding the choice to manage nuisance algae and the selection of an appropriate management approach. © Copyright 2016 West Michael Bishop All Rights Reserved A Risk-based Decision Information System for Selecting an Algal Management Program by West Michael Bishop A dissertation submitted to the Graduate Faculty of North Carolina State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy Crop Science Raleigh, North Carolina 2016 APPROVED BY: _______________________________ _______________________________ Dr. -

On Different Host Plants
Riis et al.: Bionomics of Cyrtomenus bergi on host plants 1 BIONOMICS AND POPULATION GROWTH STATISTICS OF CYRTOMENUS BERGI (HEMIPTERA: CYDNIDAE) ON DIFFERENT HOST PLANTS LISBETH RIIS1,2, ANTHONY CHARLES BELLOTTI1 AND BERNARDO ARIAS1 1Centro International de Agricultural Tropical (CIAT), Pest and Disease Management Unit A.A. 6713 Cali, Colombia S.A. 2Department of Ecology and Molecular Biology, Royal Veterinary and Agricultural University (RVAU) Copenhagen, Denmark ABSTRACT Cyrtomenus bergi Froeschner (Hemiptera: Cydnidae) is a polyphagous subterranean bur- rower bug reported on various crops and weeds in the field. Bionomics and population growth statistics of C. bergi while feeding on peanut (Arachis hypogaea L.), pinto peanut (Arachis pintoi, Krapovickas et Gregory), maize (Zea mays L.), sorghum (Sorghum bicolor [L.] Moench), welsh onion (Allium fistulosum L.),and sweet and bitter cassava (Manihot es- culenta Crantz) were calculated from development time, survival of immature stages, and reproduction and female longevity under laboratory conditions. Free-choice host plant selec- tion among peanut, maize and sweet cassava was recorded with separate rearings of C. bergi from the different hosts. Optimal performance of C. bergi as measured by fecundity, sur- vival, and intrinsic rate of population increase occurred on peanut and pinto peanut followed by maize. Sweet cassava, sorghum, and welsh onion were not favorable hosts, and C. bergi was unable to complete its life cycle on bitter cassava. In the free-choice test, insects reared on peanut and maize prior to the experiments were less active in their search for food, whereas insects reared on cassava prior to the experiment showed a clear preference for pea- nut and maize over cassava. -

Scholler, G. Hagedorn & A. Rubner (1999). A reevaluation of predatory orbiliaceous fungi. II. A new generic concept. - Sydowia 51(1): 89-113. A new genus concept is proposed for predatory anamorphic Orbiliaceae in which the trapping device is the main morphological criterion for the delimitation of the genera. Molecular, ecological, physiological, biological, and further mor- phological features are taken into account as well. Following the groups identified by Hagedorn & Scholler (1999), these predatory fungi are divided into four genera: Arthrobotrys Corda forming adhesive networks, Drechslerella Subram. forming constricting rings, Dactylellina M. Morelet forming stalked adhesive knobs, and Gamsylella gen. nov. for species producing adhesive columns and unstalked knobs. Eighty-two species are accepted, for 51 of which new combinations are proposed.

Publishing Partner: Scientific Research Journal (SCIRJ) Website: http://www.scirj.org/ ISSN: 2201-2796 Scientific Research Journal (SCIRJ) ISSN 2201-2796 Preface Biological water quality assessment of water being supplied to Male hostels at Obafemi Awolowo University, Ile Ife was done by collecting samples from flowing tap and storage tanks in each hostel over a period of six weeks. The tap and storage water supplied to the male hostels was found to consist of a total of 46 genera of plankton of which 15 were zooplankton and 31 were phytoplankton. The genera belong to 7 phytoplankton phyla (Bacillarophyta, Chlorophyta,Euglenophyta, Ochrophyta,Dinoflagellata, Cyanobacteria and Charophyta)and 5 zooplankton phyla (Cercozoa, Rotifera, Amoebozoa, Arthropoda and Ciliophora).Class Zynematophyceae (Division Charophyta)was the most abundant phytoplankton, represented by six species (Closterium ehrenbergii, Strogonium, Genicularia, Zygnemopsis, Docidium and Zygnema). Of these species, Genicularia was the most abundant. Amongst the Zooplankton,Mononogonta was the most abundant as represented by nine species namely Argonotholca foliacea, Trichocerca bicristata, Trichocerca chatonni, Trichocerca elongata, Trichocerca porcellus, Trichocerca similis, Brachionus calyciflorus, Brachionus falcatus and Hexarthra mira. The most abundant zooplankton species was Cyclops bicuspidatus of the class Maxillopoda. The highest total abundance was recorded at the sixth week of sampling. -
Taxonomy and Nomenclature of the Conjugatophyceae (= Zygnematophyceae)
Review Algae 2013, 28(1): 1-29 http://dx.doi.org/10.4490/algae.2013.28.1.001 Open Access Taxonomy and nomenclature of the Conjugatophyceae (= Zygnematophyceae) Michael D. Guiry1,* 1AlgaeBase and Irish Seaweed Research Group, Ryan Institute, National University of Ireland, Galway, Ireland The conjugating algae, an almost exclusively freshwater and extraordinarily diverse group of streptophyte green algae, are referred to a class generally known as the Conjugatophyceae in Central Europe and the Zygnematophyceae elsewhere in the world. Conjugatophyceae is widely considered to be a descriptive name and Zygnematophyceae (‘Zygnemophyce- ae’) a typified name. However, both are typified names and Conjugatophyceae Engler (‘Conjugatae’) is the earlier name. Additionally, Zygnemophyceae Round is currently an invalid name and is validated here as Zygnematophyceae Round ex Guiry. The names of orders, families and genera for conjugating green algae are reviewed. For many years these algae were included in the ‘Conjugatae’, initially used as the equivalent of an order. The earliest use of the name Zygnematales appears to be by the American phycologist Charles Edwin Bessey (1845-1915), and it was he who first formally redistrib- uted all conjugating algae from the ‘Conjugatae’ to the orders Zygnematales and the Desmidiales. The family Closte- riaceae Bessey, currently encompassing Closterium and Spinoclosterium, is illegitimate as it was superfluous when first proposed, and its legitimization is herein proposed by nomenclatural conservation to facilitate use of the name. The ge- nus Debarya Wittrock, 1872 is shown to be illegitimate as it is a later homonym of Debarya Schulzer, 1866 (Ascomycota), and the substitute genus name Transeauina Guiry is proposed together with appropriate combinations for 13 species currently assigned to the genus Debarya Wittrock. -
Hidden Genetic Diversity in the Green Alga Spirogyra (Zygnematophyceae, Streptophyta) Charlotte Chen1, Michael HJ Barfuss2, Thomas Pröschold1,3 and Michael Schagerl1*
Chen et al. BMC Evolutionary Biology 2012, 12:77 http://www.biomedcentral.com/1471-2148/12/77 RESEARCH ARTICLE Open Access Hidden genetic diversity in the green alga Spirogyra (Zygnematophyceae, Streptophyta) Charlotte Chen1, Michael HJ Barfuss2, Thomas Pröschold1,3 and Michael Schagerl1* Abstract Background: The unbranched filamentous green alga Spirogyra (Streptophyta, Zygnemataceae) is easily recognizable based on its vegetative morphology, which shows one to several spiral chloroplasts. This simple structure falsely points to a low genetic diversity: Spirogyra is commonly excluded from phylogenetic analyses because the genus is known as a long-branch taxon caused by a high evolutionary rate. Results: We focused on this genetic diversity and sequenced 130 Spirogyra small subunit nuclear ribosomal DNA (SSU rDNA) strands of different origin. The resulting SSU rDNA sequences were used for phylogenetic analyses using complex evolutionary models (posterior probability, maximum likelihood, neighbor joining, and maximum parsimony methods). The sequences were between 1672 and 1779 nucleotides long. Sequence comparisons revealed 53 individual clones, but our results still support monophyly of the genus. Our data set did not contain a single slow-evolving taxon that would have been placed on a shorter branch compared to the remaining sequences. Out of 130 accessions analyzed, 72 showed a secondary loss of the 1506 group I intron, which formed a long-branched group within the genus. The phylogenetic relationship to the genus Spirotaenia was not resolved satisfactorily. The genetic distance within the genus Spirogyra exceeded the distances measured within any other genus of the remaining Zygnemataceae included in this study. Conclusion: Overall, we define eight distinct clades of Spirogyra, one of them including the genus Sirogonium. -
