Synopsis top ↑

This volume is dedicated to Professor Greta A. Fryxell in recognition of her long and distinguished career in the taxonomy and ecology of phytoplankton, especially the diatoms, and the considerable influence she has had on all those who have interacted with her and as a mentor of young scientists.

It features 21 original, reviewed papers, thematically delineating the realm of Prof. Fryxell's work, ranging from morphology, taxonomy, molecular genetics, (harmful) algal blooms, their ecology, palaeontology, the temporal variation to the identification and description of new pyhtoplankton/diatom species.

The geographic scope of the phytoplankton-, especially diatom papers in this volume is worldwide and includes studies which focus on the US, polar regions, Chile, Antarctica, Brazil, Gulf of Mexico and Poland.

The papers were contributed by Fryxell's collaborators, colleagues, students and her children.

This special issue of Nova Hedwigia Beihefte is dedicated to the well known diatomist and marine plankton biologist Greta A.Fryxell. A first section of the book (pp. ixxviii) is devoted to Greta Fryxell’s long and distinguished career, including some biographical elements together with a list of her publications (from 1970 to 2003) and some tributes by former students and colleagues, among which a note by Eugene Stoermer on «Greta A.Fryxell’s contributions to diatom taxonomy». This section ends in a short «picture gallery» and, somewhat curiously, with some colour plates illustrating papers following later in the volume.

The second part of the book (pp. 1-329) includes twenty-one scientific papers ordered in three groups according to their authors: ten articles contributed by her former students, eight articles by her colleagues and three articles by her children. From this latter group we can see the variety of scientific interests shown by her children, including evolution of cyanobacteria, geological research or water purification by means of nanomaterials.

More than half of the phycological papers deal with taxonomy, morphology and evolution of diatoms, especially of the following taxa: Minidiscus trioculatus, Odontella aurita and O. longicruris, Thalassiosira lacustris, some species of Coscinodiscus, Fragilariopsis cylindrus and F. nana, Pseudauliscus radiatus and Fryxelliella floridana and a number of araphid genera. Two new genera are described: (1) Poloniasira fryxelliana Kaczmarska & Ehrman, n. gen., n. sp., a new fossil thalassiroid diatom from Poland and (2) Mastodiscus Bail. ex Prasad & Nienow, a new genus of recent marine diatoms, based on a forgotten «nomen nudum» of Bailey to accommodate Pseudauliscus radiatus (Bail.) Schmidt which appeared to be different enough from P. peruvianus to be considered a genus of its own.

Other papers on diatoms include morphological observations and phylogenetic studies on psychrophilic polar diatoms, observations on chain formation as evidenced by the early diatom fossil record and an assessment of recent genera in the araphids using molecular data. In the latter article, molecular analyses seem to demonstrate that the group of species around Synedra ulna (Fragilaria subgen. Ulnaria) would be generically different from Fragilaria. If this is established, the correct name of this genus under the current code of nomenclature would be Ulnaria and not Synedra as proposed by the authors since the type of the genus name Synedra is S. balthica (= S. gaillonii) which implies that only the genus including S. gaillonii could be called Synedra (and not Catacombas, as proposed by the authors).

Physiology and biochemistry of the diatoms include a study on salinity and domoic acid production in Pseudo-nitzschia multiseries and another on intracellular ion concentration and cell sap density in buoyant oceanic phytoplankton.

Studies on marine phytoplankton concern bloom ecology in the Inner Sea of Chiloé (Chile), the surf-zone of the State of São Paulo, Brazil and the picoplankton of the Atlantic sector of the Southern Ocean, this one involving mainly the prokaryotes Synechococcus and Prochlorococcus and some undetermined picoeukaryotes.

Three further papers deal with Dinophyceae: a short note on a Protoperidinium grazing on a colony of Phaeocystis, a paper on the identification of the Kareniaceae in the Gulf of Mexico and another on a new buoy-based in-situ optical early warning system for harmful algal blooms, specially designed for detecting blooms of the harmful dinoflagellate Karenia brevis.

The book will be of interest for all diatomists and for the phycologists involved in studies on marine phytoplankton but also for researchers and other people involved in the prevention and struggle against harmful algal blooms.
