NORRIS SMITHSONIAN CONTRIBUTIONS TO THE MARINE SCIENCES SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world cf science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. -

García-Soto, Juan M. Lopez-Bautista The University of Alabama, Department of Biological Sciences, Science and Engineering Complex, 1325 Hackberry Ln, Tuscaloosa, AL 35401, USA. Corresponding author: Gabriela García-Soto, [email protected] Abstract We record Acanthophora dendroides Harvey for the first time in the Atlantic Ocean. Two specimens from the Philip- pines were resolved as conspecific to the Atlantic A. dendroides in molecular analyses extending its geographic range to the Philippines. In light of new evidence provided by field-collected specimens ofAcanthophora spicifera (M.Vahl) Børgesen (generitype) from Florida and Venezuela, the flattened species A. pacifica(Setchell) Kraft, showed no affin- ity to Acanthophora sensu stricto, suggesting that the genus should be restricted to cylindrical species only.

Email: [email protected] Abstract Considerable uncertainty surrounds the phylogenetic position of Polysiphonia scopulorum, a species with an apparently cos- mopolitan distribution. Here we report, for the first time, molecular phylogenetic analyses using plastid rbcL gene sequences and morphological observations of P. scopulorum collected from the type locality, Rottnest Island in Western Australia. Mor- phological characteristics of the Rottnest Island specimens allowed unequivocal identification, however, the sequence analy- ses uncovered discrepancies in previous molecular studies that included specimens identified as P. scopulorum from other locations. The phylogenetic evidence clearly revealed that P. scopulorum from Rottnest Island formed a sister clade with P. caespitosa from Spain (JX828149 as P. scopulorum) with moderate support, but that it differed from specimens identified as P. scopulorum from the U.S.A. (AY396039, EU492915). In light of this, we suggest that P. scopulorum be considered an endemic species with a distribution restricted to Australia. -

Agradeço pela disponibilidade sempre prestada, pelos ensinamentos, conselhos e sobretudo pelo apoio em altura mais complicadas. Ao Professor Doutor Ignacio Bárbara por me ter auxiliado na identificação e confirmação de algumas espécies de macroalgas. E ao Professor Doutor António Xavier Coutinho por me ter cedido gentilmente, diversas vezes, o seu microscópio com câmara fotográfica incorporada, o que me permitiu tirar belas fotografias que serviram para ilustrar este trabalho. Ao meu colega Rui Gaspar pelo interesse demonstrado pelo meu trabalho, auxiliando-me sempre que necessário e também pela transmissão de conhecimentos. Ao Sr. José Brasão pela paciência e pelo auxílio técnico no tratamento das amostras. Em geral, a todos os meus amigos que me acompanharam nesta etapa de estudante de Coimbra e que me ajudaram a sê-lo na sua plenitude, e em particular a três pessoas: Andreia, Rita e Vera pelas nossas conversas e pelo apoio que em determinadas etapas foram muito importantes e revigorantes.

Lane Jason Kolbe Tatiana Rynearson Nasser H. Zawia DEAN OF THE GRADUATE SCHOOL UNIVERSITY OF RHODE ISLAND 2017 ABSTRACT Parasitism is a common life strategy throughout the eukaryotic tree of life. Many devastating human pathogens, including the causative agents of malaria and toxoplasmosis, have evolved from a photosynthetic ancestor. However, how an organism transitions from a photosynthetic to a parasitic life history strategy remains mostly unknown. Parasites have independently evolved dozens of times throughout the Florideophyceae (Rhodophyta), and often infect close relatives. This framework enables direct comparisons between autotrophs and parasites to investigate the early stages of parasite evolution.
