Beiheft 130: Crawford, Richard M., Brian Moss, David G. Mann, Hans R. Preisig: Microalgal Biology, Evolution and Ecology. Volume dedicated to Professor Frank Round. 2006. 466 figs. 35 tabs. 17 pls. XV, 391 p. gr8vo. Paper bd.

Microalgal Biology, Evolution and Ecology begins with a preface about the long and very productive career of Frank E. Round in algal research followed by an extensive list of his publications (176), many of which are of fundamental importance. The book contains 25 articles related to one of the many varying aspects of diatom research, ranging from morphogenesis and systematics to diatom ecology and stratigraphy, along with several articles on other algalgroups. Eleven articles pertain to either morphology or systematics of which 4 describe new species (marked with *) while six articlesare related to ecology. Morphology and Systematics (titles summarized): 1) Species of the genus Pseudo-nitzschia (M.E. Ferrario & S. Licea) 2) Notes of classification of Fragilaria, Synedra and sub-groups (D.M. Williams) 3) * Mastogloia corrugate Kemp & Basson sp. nov. (K.D. Kemp & P.W. Basson) 4) Genus Karayevia with proposal to reject Kolbesia, contains a series of new combinations (L.N. Bukhtiyarova) 5) The transfer of Radialiplicata sol andR. clavigera to Ellerbeckia (R.M. Crawford & P.A. Sims) 6) Raphe loss and spine formation in Diademis glalica (E.J. Cox) 7) *Haloroundia - a new monoraphid diatom (C.A. Diaz & N.I. Maidana) 8) Proboscia truncate - auxospores, initial cells and vegetative cells (R.W. Jordan & R. Ligowski) 9) Pseudauliscus peruvianus lectotypication and systematics of genus (A.K.S.K. Prasad, J.A. Nienow & K.A. Riddle) 10) *Nitzschia bicapitata group and Pseudo-nitzschia with a new species Pseudonitzschia roundii (D.U. Hernández-Becerril & E.M. Diaz-Almeyda) 11) *Mediopyxis helysia gen. nov and sp. nov., includessequencing and phylogenetic analysis (S.F. Kühn, G. Klein, H. Halliger, P.E. Hargraves & L.K. Medlin) Ecology (titles summarized): 1) Phytoplankton populations of Bala Lake, Wales (C.M. Happey-Wood) 2) What determines submerged freshwater diatom communities - implications to indices (J. Fisher, C. James & B. Moss) 3) Asterionella formosa seasonal periodicity (B. Sen) 4) Abundance and seasonality of phytoplankton in a Turkish Lake (G. Aykulu, M. Albay, R. Akçaalan, H. Tüfekçi & Y. Aktan) 5) Understanding phytobenthic assemblages and implications of determining ecological status (M.L. Yallop &M.G. Kelly) 6) Ecology of Cyclotella comensis group in Ontariolakes, Canada (P. Werner & J.P. Smol) Morphogenesis was discussed in several articles, one byD.G. Mann based on the analysis of pattern faults in the Voigt zone and the other by R.M. Pollock & J.D. Pickett- Heaps on valve formation without mitosis in Ditylum recovering from plasmolysis. E. Coxs article on Diadesmis gallica also fell in this category. Two articles containing stratigraphy interpretation were written, one by I. Koizumi & M. Shioho about diatoms from sapropels in the eastern Mediterranean and the other about the persistent low diatom plankton diversity in Lake Baikal by M.B. Edlund. Another Nova Hedwigia.
