Four years have passed since our bid to host the 24th International Diatom Symposium in Québec City was submitted to ISDR. This time has passed like a whirlwind and we are honoured and delighted to welcome you to the oldest French-speaking university in North America, with more than 45,000 students enrolled. From the very beginning, our aim has been to bring together experts from all fields of research on modern and fossil diatoms (both from marine and freshwater systems), including molecular, physiological, evolutionary, ecological, biogeographical, paleoecological, biomonitoring, systematic/taxonomic, and other aspects of research on diatoms. Today we are proud to announce a rich and diverse symposium program including several parallel oral sessions with a total of 84 talks, 101 poster presentations, 7 eminent plenary speakers, 5 workshops and 5 tributes and, last but not least, the first ever IDS Young Scientists Meeting! All together, we are pleased to welcome 189 participants from 6 continents and 28 countries. We hope that you will find the time to discover the major tourist attractions in Québec City with its numerous historic sites and its European flair, as well as the mighty St. Lawrence River, during or after the symposium. The mid-symposium excursion to Old Québec is meant to give you a taste of the beauty of the only walled city in North America, which is a UNESCO World Heritage site. Those who are going on the post-symposium excursion will be able to visit other tourist attractions in the Province of Québec. Please also join us in the evenings for fun “extracurricular” activities to experience Québec nightlife! We wish you inspiring and interesting exchanges with old and new friends during the 24th IDS, as well as pleasant discoveries during your stay in Québec and Canada. Enjoy the meeting!

Its volcanic origin and remoteness from the Baja California peninsula have allowed for the successful establishment of its distinctive flora and fauna. However, the difficulty in accessing the island has precluded the study of its biotic communities, mainly the marine ones. Consequently, no studies on benthic or planktonic diatoms have been hitherto published. Thus, the first records of marine benthic diatom species (epiphytic, epilithic, epizoic) from Guadalupe Island in the NW Mexican Pacific are here provided. One hundred and nineteen diatom taxa belonging to the Bacillariophyceae and Fragilariophyceae were identified, including species and varieties.

  • 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). The history of 1988, for de®nitions of mature and immature ¯agella), as well heterokont algae was recently discussed in detail (Andersen, as some nonphotosynthetic relatives and some that have sec- 2004), and four distinct periods were identi®ed.

Ponds are highly dynamic and challenging environments and display a wide range of trophic conditions. In farms affected by vibriosis, phytoplankton biomass and composition are highly variable. These conditions may promote the development of harmful algae increasing shrimp susceptibility to bacterial infections. Phytoplankton compartment before and during mortality outbreaks was monitored at a shrimp farm that has been regularly and highly impacted by these diseases.

    Modeling the biogeography of pelagic diatoms of the Southern Ocean Dissertation zur Erlangung des akademischen Grades doctor rerum naturalium (Dr. rer. nat.) der Mathematisch-Naturwissenschaftlichen Fakultät der Universität Rostock vorgelegt von Stefan Pinkernell Bremerhaven, 16.11.2017 Gutachter 1.

Prof. Dr. Anya Waite Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung Am Handelshafen 12, 27570 Bremerhaven Datum der Einreichung: 03.08.2017 Datum der Verteidigung: 11.12.2017 ii Abstract Species distribution models (SDM) are a widely used and well-established method for biogeographical research on terrestrial organisms. Though already used for decades, experience with marine species is scarce, especially for protists. More and more obser- vation data, sometimes even aggregated over centuries, become available also for the marine world, which together with high-quality environmental data form a promising base for marine SDMs. In contrast to these SDMs, typical biogeographical studies of diatoms only considered observation data from a few transects. Species distribution methods were evaluated for marine pelagic diatoms in the South- ern Ocean at the example of F. kerguelensis. Based on the experience with these models, SDMs for further species were built to study biogeographical patterns. The anthropogenic impact of climate change on these species is assessed by model projec- tions on future scenarios for the end of this century. Besides observation data from public data repositories such as GBIF, own observa- tions from the Hustedt diatom collection were used. The models presented here rely on so-called presence only observation data.

  • Sophie's World
    Sophie’s World Jostien Gaarder Reviews: More praise for the international bestseller that has become “Europe’s oddball literary sensation of the decade” (New York Newsday) “A page-turner.” —Entertainment Weekly “First, think of a beginner’s guide to philosophy, written by a schoolteacher ... Next, imagine a fantasy novel— something like a modern-day version of Through the Looking Glass. Meld these disparate genres, and what do you get? Well, what you get is an improbable international bestseller ... a runaway hit... [a] tour deforce.” —Time “Compelling.” —Los Angeles Times “Its depth of learning, its intelligence and its totally original conception give it enormous magnetic appeal ... To be fully human, and to feel our continuity with 3,000 years of philosophical inquiry, we need to put ourselves in Sophie’s world.” —Boston Sunday Globe “Involving and often humorous.” —USA Today “In the adroit hands of Jostein Gaarder, the whole sweep of three millennia of Western philosophy is rendered as lively as a gossip column ... Literary sorcery of the first rank.” —Fort Worth Star-Telegram “A comprehensive history of Western philosophy as recounted to a 14-year-old Norwegian schoolgirl... The book will serve as a first-rate introduction to anyone who never took an introductory philosophy course, and as a pleasant refresher for those who have and have forgotten most of it... [Sophie’s mother] is a marvelous comic foil.” —Newsweek “Terrifically entertaining and imaginative ... I’ll read Sophie’s World again.” — Daily Mail “What is admirable in the novel is the utter unpretentious-ness of the philosophical lessons, the plain and workmanlike prose which manages to deliver Western philosophy in accounts that are crystal clear.

  • First Identification of Marine Diatoms with Anti-Tuberculosis Activity
    www.nature.com/scientificreports Correction: Author Correction OPEN First identifcation of marine diatoms with anti-tuberculosis activity Received: 11 October 2017 Chiara Lauritano1, Jesús Martín2, Mercedes de la Cruz2, Fernando Reyes 2, Accepted: 21 January 2018 Giovanna Romano 1 & Adrianna Ianora1 Published: xx xx xxxx Marine microalgae are considered a potentially new and valuable source of biologically active compounds for applications in several biotechnology sectors. They can be easily cultured, have short generation times and enable an environmentally-friendly approach to drug discovery by overcoming problems associated with the over-utilization of marine resources and the use of destructive collection practices. Considering the increasing rate of antibiotic-resistance bacteria and infections by fungi, 46 microalgae have been screened in this study for possible antibacterial and antifungal activities. Two diferent extraction methods have been used in order to increase the probability of fnding positive hits. In particular, we screened microalgae in both control and nutrient stress conditions. We also tested diferent strains for 7 species in order to study potentially diferent bioactivities due to strain diversity. Results showed that extracts of two diatoms, Skeletonema costatum and Chaetoceros pseudocurvisetus, had anti-tuberculosis activity and were active only when cultured in the control and phosphate- starvation conditions, while the nitrogen starvation condition showed no activity. In addition, we tested both the organic and water extracts and found that only the organic extracts for both diatoms were active. The organic extracts of these two diatom species were not toxic on normal human cell lines. Microalgae are eukaryotic plants that contribute up to 25% of global productivity and 50% of all aquatic pro- ductivity1,2.
