Abstract: The present report presents the surveys of marine flora 2013 – 2014 in the San Ignacio Lagoon of the, representing the 50% of planned visits and in where we were able to identifying 19 species of macroalgae to the area plus 2 Seagrass traditionally cited. The analysis of the number of species / distribution of macroalgae and seagrass is in progress using an intense review of literature who will be concluded using the last field trip information in May-June 2014. During the last two years we have not been able to find large abundances of species of microalgae as were described since 2006 and the floristic lists developed in the 90's. This added with the presence to increase both coverage and biomass of invasive species which makes a real threat to consider. -

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. -

Resolving Cryptic Species of Bossiella (Corallinales, Rhodophyta) Using Contemporary and Historical DNA 1
RESEARCH ARTICLE AMERICAN JOURNAL OF BOTANY Resolving cryptic species of Bossiella (Corallinales, Rhodophyta) using contemporary and historical DNA 1 Katharine R. Hind 2,3,6 , Kathy Ann Miller4 , Madeline Young2 , Cassandra Jensen2 , Paul W. Gabrielson 5 , and Patrick T. Martone 2,3 PREMISE OF THE STUDY: Phenotypic plasticity and convergent evolution have long complicated traditional morphological taxonomy. Fortunately, DNA sequences provide an additional basis for comparison, independent of morphology. Most importantly, by obtaining DNA sequences from historical type specimens, we are now able to unequivocally match species names to genetic groups, often with surprising results. METHODS : We used an integrative taxonomic approach to identify and describe Northeast Pacif c pinnately branched species in the red algal coralline genus Bossiella , for which traditional taxonomy recognized only one species, the generitype, Bossiella plumosa. We analyzed DNA sequences from histori- cal type specimens and modern topotype specimens to assign species names and to identify genetic groups that were dif erent and that required new names. Our molecular taxonomic assessment was followed by a detailed morphometric analysis of each species. KEY RESULTS: Our study of B. plumosa revealed seven pinnately branched Bossiella species. Three species, B. frondescens , B. frondifera , and B. plumosa , were assigned names based on sequences from type specimens. The remaining four species, B. hakaiensis , B. manzae , B. reptans , and B. montereyensis , were described as new to science. In most cases, there was signif cant overlap of morphological characteristics among species. CONCLUSIONS: This study underscores the pitfalls of relying upon morpho-anatomy alone to distinguish species and highlights our likely underestimation of species worldwide. -

Cellulose-Rich Secondary Walls in Wave-Swept Red Macroalgae Fortify

Martone1,2 · Kyra Janot1,2 · Miki Fujita2 · Geofrey Wasteneys2 · Katia Ruel3 · Jean‑Paul Joseleau3 · José M. Estevez4,5 Received: 4 March 2019 / Accepted: 27 August 2019 / Published online: 3 September 2019 © Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract Main conclusion Cellulosic secondary walls evolved convergently in coralline red macroalgae, reinforcing tissues against wave-induced breakage, despite diferences in cellulose abundance, microfbril orientation, and wall structure. Abstract Cellulose-enriched secondary cell walls are the hallmark of woody vascular plants, which develop thickened walls to support upright growth and resist toppling in terrestrial environments. Here we investigate the striking presence and convergent evolution of cellulosic secondary walls in coralline red algae, which reinforce thalli against forces applied by crashing waves. Despite ostensible similarities to secondary wall synthesis in land plants, we note several structural and mechanical diferences. In coralline red algae, secondary walls contain three-times more cellulose (~ 22% w/w) than primary walls (~ 8% w/w), and their presence nearly doubles the total thickness of cell walls (~ 1.2 µm thick). Field emission scanning electron microscopy revealed that cellulose bundles are cylindrical and lack any predominant orientation in both primary and secondary walls. His-tagged recombinant carbohydrate-binding module diferentiated crystalline and amorphous cellulose in planta, noting elevated levels of crystalline cellulose in secondary walls. With the addition of secondary cell walls, Cal- liarthron genicular tissues become signifcantly stronger and tougher, yet remain remarkably extensible, more than doubling in length before breaking under tension. -
