Waukegan Harbor AOC is located in extreme northeast Illinois, within the City of Waukegan, on the western shore of Lake Michigan. The Waukegan Harbor AOC has a list of beneficial use impairments (BUIs) that must be addressed to improve overall water quality. The BUIs include degradation of

  • The Ecology and Glycobiology of Prymnesium Parvum
    The Ecology and Glycobiology of Prymnesium parvum Ben Adam Wagstaff This thesis is submitted in fulfilment of the requirements of the degree of Doctor of Philosophy at the University of East Anglia Department of Biological Chemistry John Innes Centre Norwich September 2017 ©This copy of the thesis has been supplied on condition that anyone who consults it is understood to recognise that its copyright rests with the author and that use of any information derived there from must be in accordance with current UK Copyright Law. In addition, any quotation or extract must include full attribution. Page | 1 Abstract Prymnesium parvum is a toxin-producing haptophyte that causes harmful algal blooms (HABs) globally, leading to large scale fish kills that have severe ecological and economic implications. A HAB on the Norfolk Broads, U.K, in 2015 caused the deaths of thousands of fish. Using optical microscopy and 16S rRNA gene sequencing of water samples, P. parvum was shown to dominate the microbial community during the fish-kill. Using liquid chromatography-mass spectrometry (LC-MS), the ladder-frame polyether prymnesin-B1 was detected in natural water samples for the first time. Furthermore, prymnesin-B1 was detected in the gill tissue of a deceased pike (Exos lucius) taken from the site of the bloom; clearing up literature doubt on the biologically relevant toxins and their targets. Using microscopy, natural P. parvum populations from Hickling Broad were shown to be infected by a virus during the fish-kill. A new species of lytic virus that infects P. parvum was subsequently isolated, Prymnesium parvum DNA virus (PpDNAV-BW1).

Twenty-five new records were identified for the Turkish freshwater algae. They belong to the following divisions: 3 to Cyanobacteria, 1 to Rhodophya, 1 to Euglenozoa, 2 to Myzozoa, 1 to Ochrophyta, 9 to Chlorophyta, and 8 to Charophyta. Key words: Algae, new record, freshwater, Dicle Reservoir, South-East Anatolian region Introduction Structures such as hydro-electric plants, and Unlike in the past, today freshwater algae research agricultural and irrigation systems built on the is progressing rapidly in Turkey. However, long- Tigris River can lead to serious ecological variations. term monitoring of changes in algal diversities Being the first of its kind in the region, this study is and population studies are rarely done.

ALVAREZ COBELAS a Ramón Margalef López RESUMEN: En este trabajo se mencionan las algas de agua dulce encontradas en España hasta julio de 1981 pertenecientes alas siguientes grupos (entre paréntesis, el número de táxones encontrados): Craspedophyceae (3), Cryptophyceae (20), Chrysophyceae (87), Dinophyceae (69), Euglenophyceae (116), Haptophyceae (9), Phaeophyceae (1), Rhodophyceae (20), Xanthophyceae (106). SUMMARY: A catalogue of Spanish freshwater algae belonging to the Classes listed below and found up to July 1981 is given. The Classes are the following (taza in brackets): Craspedo- phyceae (3), Cryptophyceae (20), Chrysophyceae (87), Dinophyceae (69), Euglenophyceae (116), Haptophyceae (9), Phaeophyceae (1), Rhodophyceae (20), Xanthophyceae (106). INTRODUCC ION El presente trabajo pretende continuar el listado de las algas de agua dulce citadas o descritas a partir de material espariol en un intento de animar al estudio de las mismas. Ya se han publicado la bibliografía sobre la que se basa (Alvarez Cobelas, 1981) y la parte dedicada a las Diatomeas (Alvarez Cobelas & Estévez, 1982). Queremos insistir en el hecho de que estos estudios se han lle- vado a cabo sobre material escrito y no sobre herbarios, casi inexis- tentes, y que sólo abarcan las publicaciones encontradas hasta julio de 1981; más adelante se confeccionarán suplementos con las incorpo- raciones posteriores a dicha fecha. Los grupos de algas incluidos en este trabajo se han ordenado en Clases y Familias siguiendo las obras de Bourrelly (1968 y 1970) y Silva (1980). Para la revisión se han consultado, además del ING (1979), las publicaciones siguientes: Cryptophyceae: Anton & Duthie (1981), Hüber-Pestalozzi (1950) y Ja- vorniciq (1976).
