Seite 4 Zusammenfassung Das Projekt befasste sich mit der Angleichung und Aktualisierung der operativen Taxaliste des Phytoplanktons (HTL) an das Kodierungssystem der Bundestaxaliste (BTL mit DV-Nr) für biologische Gewässeruntersuchungen. Im Rahmen der Angleichung beider Listen wird die HTL Teilmenge der BTL, und ist über die gemeinsame Kodierung mittels DV-Nr. verknüpfbar. Beide Listen mit Stand vom März 2009 bzw. Juni 2011 waren nicht mehr aktuell. Es waren zahlreiche Namensänderungen nötig, die auf neuen Erkenntnissen zur Systematik beruhen. Weiterhin benötigten einige bisher übersehene Arten eine angepasste Kodierung, die durch die intensiven Untersuchungen im Rahmen der Monitoringprogramme zur Wasserrahmenrichtlinie (WRRL) nachgewiesen wurden. Der vorliegende Bericht beschreibt die Vorgehensweise der Aktualisierung der HTL. Zusammen- fassende Beschreibungen der Aufgaben und Vorgehensweise finden sich auch in den Beiträgen von Mischke et al. (2018) und Hoehn et al. (2018). Zum Bericht gehören benutzerorientierte Projektprodukte, deren Inhalte und Pläne zur Veröffent- lichung im Folgenden näher erläutert werden. Für Berichtszwecke stehen sie unter folgendem Link bis zum 31. Mai 2018 zum Download für die LAWA-interne Nutzung zur Verfügung: https://nimbus.igb-berlin.de/index.php/s/8alwlosuIIvIDTs a) HTL_2018_vorab_o_BTL_Revi.xlsx b) HTL_2009_ergGeokörperInfo.xlsx c) Begleittext_Taxon_Steckbriefe_Phytoplankton_Vorab.pdf d) 50 Steckbriefe von Indikatortaxa des Phytoplanktons im Vorabdruck der 1. Lieferung (PDF-Files) Die Revision der HTL erfolgte nach einem Konzept, welches in einem vorangegangenen Projekt (LFP O2.16; Mischke et al. 2016) abgestimmt wurde, und hat als Produkt eine aktualisierte und erweiterte operative Taxaliste in Tabellenformat (Produkt a). Neben der nomenklatorischen Revision wurden folgende zusätzliche, qualitätssichernde Informationen im Projekt zusammengestellt: Einarbeitung von Geokörperinformationen zur Biovolumenberechnung (enthalten in Produkt a und Erläuterungen in Produkt b) und Erarbeitung einer Formatvorlage für Taxa-Steckbriefe (Produkt d) und Steckbriefe für ausgewählte Indikatorarten (Produkt c). Die nomenklatorische Aktualisierung aller 1.553 Phytoplanktontaxa in der HTL stellte die Haupt- aufgabe des Projektes dar. Sie basierte auf der Auswertung umfangreicher taxonomischer Fachlitera- tur. Die Liste an neuen Bestimmungswerken und relevanten Publikationen wurde gegenüber dem vorangegangenen Projekt nochmals erweitert. Im ersten Schritt wurde in der HTL der Revisionsbedarf pro Taxon markiert und in einem zweiten Schritt alle erforderlichen Informationen in Form einer Revisionstabelle zusammengestellt, um a) die Einarbeitung in die HTL und b) in die BTL vorzubereiten. Dafür wurden 213 Synonyme mit einem Verweis auf den neu akzeptierten Taxonnamen versehen. Die neuen Taxonnamen und die dazu gehörenden neuen Gattungen wurden mit einem separaten Code an die Liste angefügt, wie es dem Vorgehen in der BTL entspricht. Meldungen von bisher nicht gelisteten Arten des Phytoplanktons wurden nach den vereinbarten Aufnahmeregeln bearbeitet (s. Kap. 4.11). Insgesamt umfasst die neue HTL 358 neue Taxanamen. Mit dem Bericht wird die aktualisierte HTL in einer Vorabversion vorgelegt (Produkt a). Nach abschließender Prüfung und Vergabe der DV-Kodierung durch die relevante Fachabteilung am LFPO2.17 – Endbericht „Angleichung Taxaliste Phytoplankton“, 30.04.2018, Mischke et al. Seite 5 Umweltbundesamt ist geplant, die HTL auf dem Internetprotal gewaesser-bewertung.de zu veröffentlichen. Die Angleichung an die BTL wurde durch die Übergabe der benötigten Feldinfor- mationen aller revidierten HTL-Taxa in Form einer vereinbarten Revisionstabelle an die relevante Fachabteilung am Umweltbundesamt durch das Projekt vorbereitet. Steht die Bundestaxaliste mit den revidierten Phytoplanktontaxa vollständig zur Verfügung, können die neu erforderlichen DV-Kodierungen an die HTL (HTL_2018_DV) und in die Tools eingefügt werden. Die Bewertungstools PhytoSee 7.1 und PhytoFluss 4.1 sollen in weiteren Projekten so vorbereitet, dass sie DV-kodierte Befundlisten verarbeiten können. Für die Index-Berechnung mit den o.g.

    Biology and Systematics of Heterokont and Haptophyte Algae1

    American Journal of Botany 91(10): 1508±1522. 2004. BIOLOGY AND SYSTEMATICS OF HETEROKONT AND HAPTOPHYTE ALGAE1 ROBERT A. ANDERSEN Bigelow Laboratory for Ocean Sciences, P.O. Box 475, West Boothbay Harbor, Maine 04575 USA In this paper, I review what is currently known of phylogenetic relationships of heterokont and haptophyte algae. Heterokont algae are a monophyletic group that is classi®ed into 17 classes and represents a diverse group of marine, freshwater, and terrestrial algae. Classes are distinguished by morphology, chloroplast pigments, ultrastructural features, and gene sequence data. Electron microscopy and molecular biology have contributed signi®cantly to our understanding of their evolutionary relationships, but even today class relationships are poorly understood. Haptophyte algae are a second monophyletic group that consists of two classes of predominately marine phytoplankton. The closest relatives of the haptophytes are currently unknown, but recent evidence indicates they may be part of a large assemblage (chromalveolates) that includes heterokont algae and other stramenopiles, alveolates, and cryptophytes. Heter- okont and haptophyte algae are important primary producers in aquatic habitats, and they are probably the primary carbon source for petroleum products (crude oil, natural gas). Key words: chromalveolate; chromist; chromophyte; ¯agella; phylogeny; stramenopile; tree of life. Heterokont algae are a monophyletic group that includes all (Phaeophyceae) by Linnaeus (1753), and shortly thereafter, photosynthetic organisms with tripartite tubular hairs on the microscopic chrysophytes (currently 5 Oikomonas, Anthophy- mature ¯agellum (discussed later; also see Wetherbee et al., sa) were described by MuÈller (1773, 1786).

    Centers of Endemism of Freshwater Protists Deviate from Pattern of Taxon Richness on a Continental Scale Jana L

    www.nature.com/scientificreports OPEN Centers of endemism of freshwater protists deviate from pattern of taxon richness on a continental scale Jana L. Olefeld1, Christina Bock1, Manfred Jensen1, Janina C. Vogt2, Guido Sieber1, Dirk Albach2 & Jens Boenigk1* Here, we analyzed patterns of taxon richness and endemism of freshwater protists in Europe. Even though the signifcance of physicochemical parameters but also of geographic constraints for protist distribution is documented, it remains unclear where regional areas of high protist diversity are located and whether areas of high taxon richness harbor a high proportion of endemics. Further, patterns may be universal for protists or deviate between taxonomic groups. Based on amplicon sequencing campaigns targeting the SSU and ITS region of the rDNA we address these patterns at two diferent levels of phylogenetic resolution. Our analyses demonstrate that protists have restricted geographical distribution areas. For many taxonomic groups the regions of high taxon richness deviate from those having a high proportion of putative endemics. In particular, the diversity of high mountain lakes as azonal habitats deviated from surrounding lowlands, i.e. many taxa were found exclusively in high mountain lakes and several putatively endemic taxa occurred in mountain regions like the Alps, the Pyrenees or the Massif Central. Beyond that, taxonomic groups showed a pronounced accumulation of putative endemics in distinct regions, e.g. Dinophyceae along the Baltic Sea coastline, and Chrysophyceae in Scandinavia. Many other groups did not have pronounced areas of increased endemism but geographically restricted taxa were found across Europe. Restricted distribution and endemism has been demonstrated for numerous protist taxa by now 1–4.

There are multiple available classification 12 systems that all suffer from differences in naming, incompleteness, presence of multiple non- 13 monophyletic entities and poor correspondence of divergence times. These issues render 14 taxonomic comparisons across the main groups of eukaryotes and all life in general difficult 15 at best. By using the monophyly criterion, roughly comparable time of divergence and 16 information from multiple phylogenetic reconstructions, I propose an alternative 17 classification system for the domain Eukarya to improve hierarchical taxonomical 18 comparability for animals, plants, fungi and multiple protist groups. Following this rationale, 19 I propose 32 kingdoms of eukaryotes that are treated in 10 subdomains. These kingdoms are 20 further separated into 43, 115, 140 and 353 taxa at the level of subkingdom, phylum, 21 subphylum and class, respectively (http://dx.doi.org/10.15156/BIO/587483).

Sogin Nucleotide ssu and lsu rDNA sequences of all major lineages of autotrophic (Ochrophyta) and heterotrophic (Bigyra and Pseudofungi) heterokonts were combined with amino acid sequences from four protein-coding genes (actin, b-tubulin, cox1 and hsp90) in a multigene approach for resolving the relationship between heterokont lineages. Applying these multigene data in Bayesian and maximum likelihood analyses improved the heterokont tree compared to previous rDNA analyses by placing all plastid-lacking heterotrophic heterokonts sister to Ochrophyta with robust support, and divided the heterotrophic heterokonts into the previously recognized phyla, Bigyra and Pseudofungi. Our trees identified the heterotrophic heterokonts Bicosoecida, Blastocystis and Labyrinthulida (Bigyra) as the earliest diverging lineages.

Accepted: August 3, 2014 Data deposition: Nine new complete mitochondrial genome sequences with annotated features have been deposited at GenBank under the accessions KJ806265–KJ806273. Genes from partially sequenced genomes have been deposited at GenBank under the accessions KJ845680– KJ845692, KJ845706–KJ845718, and KJ845693–KJ845705. 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.
