This study provides a comprehensive characterization of the chemical composition of 15 Arctic red algal species from the perspective of their practical relevance in medicine and the food industry. We show that several virtually unstudied species may be regarded as promis- ing sources of different valuable metabolites and minerals. Thus, several filamentous ceramialean algae (Ceramium virgatum, Polysiphonia stricta, Savoiea arctica) had total protein content of 20–32% of dry weight, which is comparable to or higher than that of already commercially exploited species Citation: Yanshin, N.; Kushnareva, (Palmaria palmata, Porphyra sp.). Moreover, ceramialean algae contained high amounts of pigments, A.; Lemesheva, V.; Birkemeyer, C.; macronutrients, and ascorbic acid.

Impacts of Altered Physical and Biotic Conditions in Rocky Intertidal Systems: Implications for the Structure and Functioning of Complex Macroalgal Assemblages
Impacts of altered physical and biotic conditions in rocky intertidal systems: implications for the structure and functioning of complex macroalgal assemblages A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at the University of Canterbury, New Zealand Tommaso Alestra 2014 Abstract Complex biogenic habitats created by large canopy-forming macroalgae on intertidal and shallow subtidal rocky reefs worldwide are increasingly affected by degraded environmental conditions at local scales and global climate-driven changes. A better understanding of the mechanisms underlying the impacts of complex suites of anthropogenic stressors on algal forests is essential for the conservation and restoration of these habitats and of their ecological, economic and social values. This thesis tests physical and biological mechanisms underlying the impacts of different forms of natural and human-related disturbance on macroalgal assemblages dominated by fucoid canopies along the east coast of the South Island of New Zealand. A field removal experiment was initially set up to test assemblage responses to mechanical perturbations of increasing severity, simulating the impacts of disturbance agents affecting intertidal habitats such as storms and human trampling. Different combinations of assemblage components (i.e., canopy, mid-canopy and basal layer) were selectively removed, from the thinning of the canopy to the destruction of the entire assemblage. The recovery of the canopy-forming fucoids Hormosira banksii and Cystophora torulosa was affected by the intensity of the disturbance. For both species, even a 50% thinning had impacts lasting at least eighteen months, and recovery trajectories were longer following more intense perturbations. Independently of assemblage diversity and composition at different sites and shore heights, the recovery of the canopy relied entirely on the increase in abundance of these dominant fucoids in response to disturbance, indicating that functional redundancy is limited in this system. -

Oxygen Microenvironment of Coralline Algal Tufts and Their Associated Epiphytic Animals
OXYGEN MICROENVIRONMENT OF CORALLINE ALGAL TUFTS AND THEIR ASSOCIATED EPIPHYTIC ANIMALS Sandra Irwin and John Davenport ABSTRACT Separate subhabitats are distinguishable in tufts of Corallina offi cinalis, including the surface of the algae itself and the interspace (areas of water) within the algal tufts. The oxygen microenviron- ment of each of these was investigated in laboratory investigations using oxygen microelectrodes to test the hypothesis that oxygen gradients form adjacent to the seaweed surface and that the oxygen concentration of the seawater between the branches of individual plants differs from that of the surrounding water body due the tuft forming nature of this seaweed. Regions of hyperoxia (up to 250% of saturation) were detected at the surface of Corallina branches in static conditions, with steep declining gradients of oxygen concentration through the diffusive boundary layer in the vertical plane to 100% of saturation a distance almost 2mm from the surface. Oxygen con- centration at the surface did not vary with position along individual branches, or with position on any one branch segment. Concentrations were signifi cantly higher on main branches than on peripheral branches of individual plants. Water fl ow was the dominant factor controlling the depth and oxygen supply of diffusive boundary layers and in moving water oxygen levels did not achieve such high saturation levels and the boundary layer was thinner. On a larger scale, oxygen concentrations in the interspace of C. offi cinalis tufts were highly variable and commonly in excess of air saturation. The oxygen environment was both temporally and spatially dynamic, and very rapid changes in oxygen concentration were observed in response to changing fl ow conditions. -
