Abstract
The mitochondrial genome (mitogenome) is essential for identifying species and tracing genetic variation, gene patterns, and evolutionary studies. Here, the mitogenome of Grateloupia turuturu was sequenced on the Illumina sequencing platform. This circular mitogenome (28,265 bp) contains 49 genes, including three rRNAs, twenty transfer RNAs (tRNAs), and twenty-six protein-coding genes (PCGs). Nucleotide composition indicates biased AT (68.8%) content. A Group II intronic sequence was identified between two exons of the cox1 gene, and this sequence comprises an open reading frame (ORF) that encodes a hypothetical protein. The gene content, annotation, and genetic makeup are identical to those of Halymeniaceae members. The complete mitogenome sequences of the Grateloupia and Polyopes species were used in a phylogenetic analysis, which revealed that these two genera are monophyletic and that G. turuturu and G. elliptica are closely related. This newly constructed mitogenome will help us better understand the general trends in the development of cox1 introns in Halymeniaceae, as well as the evolution of red algal mitogenomes within the Rhodophyta and among diverse algal species.

Abstract
Plastics are the most abundant marine litter in the world's oceans and can be degraded into micro-plastics. These emerging pollutants negatively affect marine organisms, but little is known on the effects on macroalgae. In this study, we investigated the effects of micro-plastics on two species of red algae: Grateloupia turuturu and Chondrus sp. Grateloupia turuturu has a slippery surface while Chondrus sp. has a rough surface. Different surface characteristics of these macroalgae may affect adherence of micro-plastics. Both species were exposed to 5 different concentrations (0, 20, 200, 2000 and 20,000 ng/L) of polystyrene microspheres. Adherence capacity, accumulating micro-plastics on the surface was higher for Chondrus sp. than G. turuturu. Chondrus sp. at 20,000 ng/L only showed a decrease in growth rate and photosynthesis activity, and an increase of reactive oxygen species (ROS). However, G. turuturu was not significantly affected by micro-plastics at all tested concentrations. Shaded light and inhibition of gas flow by adhered micro-plastics may be a reason for the reduction of growth and photosynthesis and production of ROS. Based on this result, the toxic effects of micro-plastics appear to be species specific, dependent on the adherence capacity of macroalgae.

Abstract
It has been predicted that Grateloupia turuturu, native of the cold-temperate waters of Japan, is one of the most invasive marine species considered as a threat to global marine biodiversity. However, few studies have been carried out to assess the extent of its spread worldwide. Its seasonal dynamics in the Mar Piccolo of Taranto, a transitional water system in the Northern Ionian Sea, were observed for ten years. Systematic monthly observations were carried out from 2008 to 2018. The length of thalli and density were measured alongside the seawater temperature. Data were processed by means of non-parametric statistical analyses. No invasive behavior was detected for G. turuturu. It seems well established in the Mar Piccolo even though its population is limited to the station of first detection. However, due to its shown preference for plastic substrate, it could become a vector of another urgent threat, that is plastic pollution.

Abstract
Marine bioinvasions are increasing worldwide by a number of factors related to the anthroposphere, such as higher ship traffic, climate change and biotic communities' alterations. Generating information about species with high invasive potential is necessary to inform management decisions aiming to prevent their arrival and spread. Grateloupia turuturu, one of the most harmful invasive macroalgae, is capable of damaging ecosystem functions and services, and causing biodiversity loss. Here we developed an ecological niche model using occurrence and environmental data to infer the potential global distribution of G. turuturu. In addition, ecophysiological experiments were performed with G. turuturu populations from different climatic regions to test predictions regarding invasion risk. Our model results show high suitability in temperate and warm temperate regions around the world, with special highlight to some areas where this species still doesn't occur. Thalli representing a potential temperate region origin, were held at 10, 13, 16, 20 and 24 °C, and measurements of optimal quantum field (Fv/Fm) demonstrated a decrease of photosynthetic yield in the higher temperature. Thalli from the population already established in warm temperate South Atlantic were held at 18, 24 and 30 °C with high and low nutrient conditions. This material exposed to the higher temperature demonstrated a drop in photosynthetic yield and significant reduction of growth rate. The congregation of modelling and physiological approach corroborate the invasive potential of G. turuturu and indicate higher invasion risk in temperate zones. Further discussions regarding management initiatives must be fostered to mitigate anthropogenic transport and eventually promote eradication initiatives in source areas, with special focus in the South America. We propose that this combined approach can be used to assess the potential distribution and establishment of other marine invasive species.

Abstract
Understanding the mechanisms underlying biological invasions is essential to separate their actual ecological effects from those of other human disturbances. This study examined experimentally whether the non-native red seaweed Grateloupia turuturu is an opportunistic species taking advantage of degraded local conditions (passenger model), or the primary driver of changes in the structure of benthic assemblages (driver model). In a first experiment, traits of G. turuturu likely associated to its invasion success were compared between unmanipulated controls and treatments subjected to the removal of canopy-forming macroalgae to test for the passenger model. In a second experiment, rock pool assemblages where G. turuturu was selectively removed were compared with initially similar control (unmanipulated) assemblages to test for the driver model. Over a period of four months, G. turuturu showed larger cover, higher number of individuals and longer fronds in the canopy-removed compared to the control pools, while no significant differences were detected between assemblages where G. turuturu was continuously removed and those where invasion was allowed to occur. Present findings suggest that G. turuturu would rely on disturbances removing potential native competitors to spread into the recipient habitat, rather than being the main driver of ecological alterations.

Abstract
A one-step chromatographic method for the purification of R-phycoerythrin (R-PE) of Grateloupia turuturu Yamada is described. Native R-PE was obtained with a purity index of 2.89 and a recovery yield of 27% using DEAE-Sepharose Fast Flow chromatography with a three-step increase in ionic strength. The analysis by SDS electrophoresis showed a broad band between 18 and 21kDa in size corresponding to subunits α and β and a low intensity band of 29kDa corresponding to the γ subunit. Two forms of R-PE were identified by gel filtration chromatography: a native form with a molecular weight of 260±5kDa and a dissociated form with a molecular weight of 60±2kDa. The native form presented the characteristic absorption spectrum of R-PE with three absorbance maxima at 498, 540 and 565nm, whereas the dissociated form presented only the 498 and 540nm peaks. Moreover, the two forms displayed two different fluorescence maxima.
