    Description / Table of Contents: Identifying Marine Diatoms and Dinoflagellates is the second identification manual created from the literature developed for the Advanced International Phytoplankton Course. This version, enlarged and modified from the earlier literature, deals with the identification of marine diatoms and dinoflagellates. The data and references presented here should allow the researcher to pursue the question of valid species and how they can be verified. This volume comprises three chapters, beginning with an introductory chapter discussing the subject's historical background. The next chapter focuses on marine diatoms, providing an introduction that describes their general characteristics, life cycles, morphology and terminology, and classification. It is followed by a discussion of genera represented in marine plankton, a description of taxa, and methodology. The third and final chapter focuses on dinoflagellates, beginning with an introduction that describes their general characteristics and eukaryotic unicells. The discussion continues with terminology and morphology, identification of species, techniques for preparation of dinoflagellates for identification, common dinoflagellate synonyms, and an index of dinoflagellate taxa. This book will be of interest to practitioners in the fields of biology, zoology, and environmental protection.

    Description: Alexandrium ostenfeldii (Paulsen) Balech and Tangen and A. peruvianum (Balech and B.R. Mendiola) Balech and Tangen are morphologically closely related dinoflagellates known to produce potent neurotoxins. Together with Gonyaulax dimorpha Biecheler, they constitute the A. ostenfeldii species complex. Due to the subtle differences in the morphological characters used to differentiate these species, unambiguous species identification has proven problematic. To better understand the species boundaries within the A. ostenfeldii complex we compared rDNA data, morphometric characters and toxin profiles of multiple cultured isolates from different geographic regions. Phylogenetic analysis of rDNA sequences from cultures characterized as A. ostenfeldii or A. peruvianum formed a monophyletic clade consisting of six distinct groups. Each group examined contained strains morphologically identified as either A. ostenfeldii or A. peruvianum. Though key morphological characters were generally found to be highly variable and not consistently distributed, selected plate features and toxin profiles differed significantly among phylogenetic clusters. Additional sequence analyses revealed a lack of compensatory base changes in ITS2 rRNA structure, low to intermediate ITS/5.8S uncorrected genetic distances, and evidence of reticulation. Together these data (criteria currently used for species delineation in dinoflagellates) imply that the A. ostenfeldii complex should be regarded a single genetically structured species until more material and alternative criteria for species delimitation are available. Consequently, we propose that A. peruvianum is a heterotypic synonym of A. ostenfeldii and this taxon name should be discontinued.

    Description: Una floración de la especie Chattonella cf subsalsa se produjo en la laguna Galafre situada en la zona sur de Pinar del Río, región suroccidental de Cuba. Es un área de importancia económica para el refugio de juveniles de especies de peces de interés comercial, langosta y del desarrollo del ostión de mangle Crassostrea rhizophorae. En diciembre de 2014 se realizó un muestreo donde se cogieron cuatro frascos de agua a nivel subsuperficial (40 cm) para determinar la abundancia de fitoplancton. Se observó que la concentración de C. cf subsalsa varió entre 298 x 103 y 936 x 103 cél./L. Esta es la primera proliferación y registro de C. cf subsalsa en la región suroccidental de Cuba. Se presenta una descripción morfológica simple de la especie.
    Description: A bloom of the species Chattonella cf subsalsa occurred in the Galafre lagoon located in the south of Pinar del Rio province, southwestern region of Cuba. It is a juvenile nursery area of commercial species with high economic importance like lobster and diverse fishes and also ideal for the development of mangrove oyster Crassostrea rhizophorae. In December 2014 samples of water, at subsurface level (40 cm) were taken in four bottles to determine the abundance of phytoplankton. It was observed that the concentration of C. cf subsalsa ranged from 298 x 103 and 936 x 103 cells./L. This is the first record of C. cf subsalsa proliferation in the southwestern region of Cuba. A simple morphological description of the species is presented.
