Nova Hedwigia Band 79 Heft 1-2. Culture Collections of Algae: Increasing Accessibility and Exploring Algal Biodiversity. Ed.: Friedl, Thomas; Day, John G.; Preisig H.R. 2004. Preface: This volume aims to outline the value of algal culture collections to the user community and, at the same time, presents the proceedings of an international meeting held in 2002, which provided a forum for algal culture collections from all over the world to improve interactions among them. Culture Collection of Algae have, in essence two key functions: They provide consistency and quality, traceable source material and information. They are, de facto, sources of biological standards and without these standards comparative taxonomic, physiological, ecotoxicological and ex situ ecological studies are impossible or, at best, problematic. The value of collections to the user community is widely recognized, not least in that they provide cultures that are often difficult or virtually impossible to re-isolate from their natural habitats, even when the original source is known and accessible. They provide a store of well characterized diversity for research and/or exploitation. The holdings of algal collections are extremely diverse and it is the collections' aim to make available and conserve ex situ as much of the great morphological and genetic biodiversity of microalgae as possible. For phylogenetic and taxonomic studies authentic strains, i.e. cultures derived from the material used for the original description and naming of the species, are particularly useful - these and the vast literature published on the algal culture collections' holdings make them irreplaceable and unique international resources.

The importance of maintaining biological resources for both scientific reasons and for possible future exploitation, or sustainable development, is receiving increasing international attention. Various initiatives highlight the unique value of culture collections as Biological Resource Centers (BRCs), the need to support and expand their holdings, and the importance of improving collaborations among collections. These initiatives served as a stimulus for the international symposium "Culture Collections of Algae: Increasing Accessibility and Exploring Algal Biodiversity", held at the Sammlung von Algenkulturen (SAG) at the University of Göttingen, Germany, September 2-6 2002. An excellent review of the meeting has been published by B. Surek in Protist 153, 343355, 2002. The 21 papers in this volume reflect the main topics of the meeting: the majority of the sessions were devoted to presentations by culture collections including historical aspects of culturing microalgae (the first thirteen papers in this volume, pp. 1-173) and the Cryopreservation of Microalgae (J.J. Brand & K.R. Diller, pp. 175-189; J.G. Day, pp. 191-205; K. Harding et al., pp. 207-226; H.C. Osório et al., pp. 227-235). In the first section of this volume we tried to provide a forum, particularly for smaller culture collections, which have had fewer opportunities, to date, to gain exposure in the scientific mainstream. Two further sessions of the meeting clearly showed the function of culture collections as valuable sources of research material, i.e. Taxonomy and Evolution of Microalgae and Cyanobacteria (D.G. Mann & V.A. Chepurnov, pp. 237-291; K. Comte et al., pp. 293-311) and Applications of rDNA Probes and DNA Microarray Techniques (R. Groben et al., pp. 313-320; K. Metfies & L.K. Medlin, pp. 321-327). It is hoped that these papers have highlighted some examples of the value of collections to the phycological community and further stimulate their scientific exploitation. 327 pages, 83 figures, 27 tables, 4 photos.  paperback, $171.00

A checklist of benthic marine algae of the tropical and subtropical western Atlantic: first revision. contents: Introduction, Format, Rhodophyta, Notes, Acknowledgements, References, Index to Genera. Since Taylor's 1960 Marine algae of the eastern tropical and subtropical coasts of the America, there has been ever-increasing interest on this subject matter. Wynne's first checklist was an attempt to compile an up-to-date catalogue of the benthic marine algae for the 3 divisions of Rhodophyta, Phaeophyta and Chlorophyta for the tropical and subtropical coastline of the western Atlantic, from North carolina to southern Brazil, using Taylor's flora as a baseline. In the past dozen years numerous publications throughout the region have added significantly to the literature with new records and taxonomic and nomenclatural changes. This revision provides an updated account of the benthic marine algale of this region. 156 pp., paperback. ISBN 3-443-51038-8. $72.00

Beih. 117: Trainor, Francis R. 1998.  Biological Aspects of Scenedesmus (Chlorophyceae) -- phenotypic plasticity. Scenedesmus is a cosmopolitan green freshwater algae. Because of the colonial symmetry of Scenedesmus, its size/shape differences and abundant cytological features (both LM and EM), it first seemed that individuals could easily be distinguished and classified.  Because biologists often examined samples of Scenedesmus taxa at only one point in time, they tacitly assumed that there was stability of form. Are there data confirming stability of form? On the other hand, preserved collections are not useful material to support an alternate hypothesis. The result: hundreds of species and innumerable subspecific taxa were identified and described. In Scenedesmus Phenotypic Plasticity the author presents - Early reports of variability or polymorphism, along with their routine dismissal as supposedly irrelevant observations. - Chapters concerned with geographical distribution, culture techniques, history and the Scenedesmus unicell, indicating the need for the renaissance of the phenotype. The concept of an ordered developmental sequence is developed and discussed. Data from numerous laboratories, whether cytological, morphological, biochemical, ecological or physiological, which lend support to the concept of  plasticity in all strains.  Numerous supposed taxa are but ecomorphs of rather complex taxa. contents: Introduction, Geographical distribution of species, Cytology & reproduction, Culturing algae: impact on Scenedesmus development, Unicells: a Scenedesmus ecomorph, Scenedesmus phenotypic plasticity: scope & consequences, A broadly defined species: S. armatus, Phenotypic plasticity in multi-spined species: response to nutrients & temperature, Selection of stable characters: morphology yesterday, today and tomorrow, Phenotypic plasticity: past, present & future, Scenedesmus identification recognizing phenotypic plasticity, References, Index.

Beiheft 125 The marine macroalgae of the tropical West Africa sub-region. John, David M.;Lawson, George W.; Ameka, Gabriel K.: 2003. Rocky shores, mangrove roots and other hard surfaces provide anchorage for seaweeds or benthic macroalgae along the environmentally relatively inhospitable coast of tropical West Africa. This user-friendly guide deals with the over 300 species of green, brown and red seaweeds known from an almost 4,000 km long stretch of West African coast (Gambia to the equator) as well as islands in the Gulf of Guinea. Descriptions and identification keys are relatively free of technical terms. Each entry takes the form of a diagnostic description of the species along with notes on its West African distribution, ecology and taxonomic or identification problems. Included are more than 250 clear line drawings and 46 colour photographs that usually emphasise features required for accurate identification.  IV , 217 pages, 56 figures, 12 colour plates , ISBN 3-443-51047-7 paperback. $129.00

Beiheft 127: A Taxonomic and Geographical Catalogue of the Seaweeds of the Western Coast of Africa and Adjacent Islands. Ed.: John, David M.; Lawson, George W.; Price, James H.; Prud'homme van Reine, Willem F.; Kostermans, Tito B. 2004. The catalogue records all species and infraspecific taxa of benthic marine algae or seaweeds known for the mainland coast of West Africa (northern boundary of Western Sahara southwards to the southern boundary of Namibia), and the western Atlantic islands between Madeira and the Salvages in the north to Ascension and St Helena in the south, including those lying relatively close to the African mainland. In all over 32 mainland countries and islands are covered. Genera, species and infraspecific taxa are arranged alphabetically within the green algae, brown algae and red algae. Under the currently accepted name there are others that have been commonly used for it in earlier publications on West Africa. Mentioned are all countries and islands from which it has been recorded with reference given to the most recent literature source. Taxonomic, nomenclatural or other information is provided where needed or a reference given to a source of such information. In total 1195 species are now accepted (202 green algae, 200 brown algae, 793 red algae) compared to 2013 recognized in lists published over the past 40 years. Despite the considerable progress made in our knowledge of West African seaweeds over this period there are countries and islands that are little-explored phycologically; no records are traced for the Democratic Republic of the Congo (=Zaire), Rio Muni (Equatorial Guinea) and Cabinda. The seaweed floras of most major island archipelagos are significantly more diverse (e.g. Canary Islands, 646 spp) than the mainland coast where just under 300 species are known for a 4,000 km length of shoreline (Gambia to southern Angola). One new combination is made, namely Chondrophycus glanduliferis (Kütz.) Prud'homme & D.M.John.139 pages, 1 figure, 24x17cm. . ISBN 3-443-51049-3 paperback, $87.00
