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.

However, canopy-forming algae are experiencing a general global decline, mostly driven by human pressures on coastal ecosystems and global changes. In contrast with their high ecological relevance, little is known about how their genetic diversity, dispersal and connectivity can be affected by global changes, despite the expected consequences for population resilience. I focused on studying brown macroalgae of the genus Cystoseira, one of the leading canopy-forming seaweed genera along European coasts, coupling molecular and ecological approaches to understand several processes that affect these marine forests. -

Without exception, you have been so kind and supportive throughout the whole process. Although I only got to explore a small part of the vast world of algae, it surely has been an inspirational and interesting journey full of new learnings. Thank you for your guidance and patience in the field, the lab, and for always answering my questions. I could not ask for a better supervisor, and it has been a pleasure to work with you. Pedro, thank you for being an excellent co-supervisor. During this thesis, I very much appreciated your positive attitude and patience. Thank you for taking your time to explain the processes behind the molecular work and for guiding me through the statistical part, which I found particularly challenging. During stressful times, your support kept me calm and made sure I did not lose focus. Also, your feedback was very much appreciated. A special thank you to co-supervisor Geir Dahle at the Institute of Marine Science (IMR) for taking your time to help with the genetic analysis, the ABI Machine, and allele scoring, which was only possible at IMR. I also want to thank you for sharing your knowledge regarding microsatellite analysis, being helpful with the statistics, and providing good feedback. -

Few of the numerous marine macroalgae are currently exploited. In this study, the contents of nutritional compounds from nine common North Atlantic red macroalgae were compared: the lipid content was low and constant among the species, whereas the fatty acid profiles indicated that these species constitute interesting sources of polyunsaturated fatty acids (PUFA). The dominating essential and non-essential amino acids were lysine and leucine, aspartic acid, glutamic acid, and arginine, respectively. The amino acid score of the nine algae varied from 44% to 92%, the most commonly first limiting amino acid be- ing histidine. -

Douglas Adams ABSTRACT The increasing demand for seaweed extracts has led to the introduction of non-native seaweeds for farming purposes in many tropical regions. Such intentional introductions can lead to spread of non-native seaweeds from farming areas, which can become established in and alter the dynamics of the recipient ecosystems. While tropical seaweeds are of great interest for aquaculture, and have received much attention as pests in the coral reef literature, little is known about the problems and potential of natural populations, or the role of natural seaweed beds in the tropical seascape. This thesis aims to investigate the spread of non-native genetic strains of the tropical macroalga Eucheuma denticulatum, which have been intentionally introduced for seaweed farming purposes in East Africa, and to evaluate the state of the genetically distinct but morphologically similar native populations. Additionally it aims to investigate the ecological role of seaweed beds in terms of the habitat utilization by fish and mobile invertebrate epifauna. The thesis also aims to evaluate the potential of native populations of eucheumoid seaweeds in regard to seaweed farming. -

Photo by Ellen Schagerström Summary The Baltic Sea is considered an ecological marginal environment, where both marine and freshwater species struggle to adapt to its ever changing conditions. Fucus vesiculosus (bladderwrack) is commonly seen as the foundation species in the Baltic Sea, as it is the only large perennial macroalgae, forming vast belts down to a depth of about 10 meters. The salinity gradient results in an increasing salinity stress for all marine organisms. This is commonly seen in many species as a reduction in size. What was previously described as a low salinity induced dwarf morph of F. vesiculosus was recently proved to be a separate species, when genetic tools were used. This new species, Fucus radicans (narrow wrack) might be the first endemic species to the Baltic Sea, having separated from its mother species F. vesiculosus as recent as 400 years ago. Fucus radicans is only found in the Bothnian Sea and around the Estonian island Saaremaa. The Swedish/Finnish populations have a surprisingly high level of clonality. -
Marine Macroalgal Biodiversity of Northern Madagascar: Morpho‑Genetic Systematics and Implications of Anthropic Impacts for Conservation

This represents the frst inventory encompass- ing the three major macroalgal classes (Phaeophyceae, Florideophyceae and Ulvophyceae) for the little-known Malagasy marine fora. Combining morphological and DNA-based approaches, we report from our collection a total of 110 species from northern Madagas- car, including 30 species of Phaeophyceae, 50 Florideophyceae and 30 Ulvophyceae. Bar- coding of the chloroplast-encoded rbcL gene was used for the three algal classes, in addi- tion to tufA for the Ulvophyceae. This study signifcantly increases our knowledge of the Malagasy marine biodiversity while augmenting the rbcL and tufA algal reference libraries for DNA barcoding. These eforts resulted in a total of 72 new species records for Mada- gascar. Combining our own data with the literature, we also provide an updated catalogue of 442 taxa of marine benthic -
Distribution of Epiphytic Macroalgae on the Thalli of Their Hosts in Cuba
Acta Botanica Brasilica 27(4): 815-826. 2013. Distribution of epiphytic macroalgae on the thalli of their hosts in Cuba Yander Luis Diez García1, Abdiel Jover Capote2,6, Ana María Suárez Alfonso3, Liliana María Gómez Luna4 and Mutue Toyota Fujii5 Received: 4 April, 2012. Accepted: 14 October, 2013 ABSTRACT We investigated the distribution of epiphytic macroalgae on the thalli of their hosts at eight localities along the sou- theastern coast of Cuba between June 2010 and March 2011. We divided he epiphytes in two groups according to their distribution on the host: those at the base of the thallus and those on its surface. We determining the dissimilarity between the zones and the species involved. We identified 102 taxa of epiphytic macroalgae. There were significant differences between the two zones. In 31 hosts, the number of epiphytes was higher on the surface of the thallus, whereas the number of epiphytes was higher at the thallus base in 25 hosts, and the epiphytes were equally distributed between the two zones in five hosts (R=−0.001, p=0.398). The mean dissimilarity between the two zones, in terms of the species composition of the epiphytic macroalgae, was 96.64%. Hydrolithon farinosum and Polysiphonia atlantica accounted for 43.76% of the dissimilarity. Among macroalgae, the structure of the thallus seems to be a determinant of their viability as hosts for epiphytes.
