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. -
Snps Reveal Geographical Population Structure of Corallina Officinalis (Corallinaceae, Rhodophyta)
SNPs reveal geographical population structure of Corallina officinalis (Corallinaceae, Rhodophyta) Chris Yesson1, Amy Jackson2, Steve Russell2, Christopher J. Williamson2,3 and Juliet Brodie2 1 Institute of Zoology, Zoological Society of London, London, UK 2 Natural History Museum, Department of Life Sciences, London, UK 3 Schools of Biological and Geographical Sciences, University of Bristol, Bristol, UK CONTACT: Chris Yesson. Email: [email protected] 1 Abstract We present the first population genetics study of the calcifying coralline alga and ecosystem engineer Corallina officinalis. Eleven novel SNP markers were developed and tested using Kompetitive Allele Specific PCR (KASP) genotyping to assess the population structure based on five sites around the NE Atlantic (Iceland, three UK sites and Spain), spanning a wide latitudinal range of the species’ distribution. We examined population genetic patterns over the region using discriminate analysis of principal components (DAPC). All populations showed significant genetic differentiation, with a marginally insignificant pattern of isolation by distance (IBD) identified. The Icelandic population was most isolated, but still had genotypes in common with the population in Spain. The SNP markers presented here provide useful tools to assess the population connectivity of C. officinalis. This study is amongst the first to use SNPs on macroalgae and represents a significant step towards understanding the population structure of a widespread, habitat forming coralline alga in the NE Atlantic. KEYWORDS Marine red alga; Population genetics; Calcifying macroalga; Corallinales; SNPs; Corallina 2 Introduction Corallina officinalis is a calcified geniculate (i.e. articulated) coralline alga that is wide- spread on rocky shores in the North Atlantic (Guiry & Guiry, 2017; Brodie et al., 2013; Williamson et al., 2016). -

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. -

Spirorbis Corallinae N.Sp. and Some Other Spirorbinae (Serpulidae) Common on British Shores
J. mar. biol. Ass. U.K. (1962) 42, 601-608 601 Printed in Great Britain SPIRORBIS CORALLINAE N.SP. AND SOME OTHER SPIRORBINAE (SERPULIDAE) COMMON ON BRITISH SHORES By P. H. D. H. DE SILVA* AND E. W. KNIGHT-JONES Department of Zoology, University College of Swansea (Text-fig. I) The Spirorbinae of Britain have not previously been studied carefully. A re• markable omission from widely used British fauna lists (Marine Biological Association, 1931; Eales, 1939, 1952) was Spirorbis pagenstecheri Quatrefages, which is by far the most generally common dextral species on British shores. Instead S. spirillum (Linne) was the only dextral species recorded in those lists, with no note of the fact that this is typically an off-shore form. Several accounts of shore ecology which mention the latter but not the former may have involved misidentifications from this cause. Another source of confusion was that McIntosh (1923) described under the name S. granulatus (Linne) a common British species which incubates its embryos in its characteristically ridged tube. In fact the first adequate description to which that name was applied was of a species with an opercular brood chamber (Caullery & Mesnil, 1897). It is therefore incorrect to apply the name to a form with tube incubation, unless one supposes that the method of incubation is variable in this species. Although Thorson (1946) was inclined to make that assumption it is unlikely to be true, for incubation in the oper• culum involves striking specializations of structure, function and habits. Indeed it is now virtually certain that two separate species are involved here, as Bergan (1953) concluded in his account of the Spirorbinae of Norway. -

Epitypification and Redescription of Corallina Officinalis L., the Type of the Genus, and C
Cryptogamie, Algologie, 2013, 34 (1): 49-56 © 2013 Adac. Tous droits réservés Epitypification and redescription of Corallina officinalis L., the type of the genus, and C. elongata Ellis et Solander (Corallinales, Rhodophyta) Juliet BRODIE*, Rachel H. WALKER, Christopher WILLIAMSON & Linda M. IRVINE Natural History Museum, Department of Life Sciences, Cromwell Road, London SW7 5BD, UK Abstract – Corallina L. is the type genus of the subfamily Corallinoideae (Aresch.) Foslie and Corallina officinalis L. is the type species of the genus. This name has been applied worldwide, particularly in temperate waters. An attempt to obtain sequence data from the lectotype specimen was not successful. In order to establish a species concept for C. officinalis based on molecular sequence data as well as morphology, an epitype was selected from Devon, England within the vague type locality ‘in O [Oceano] Europaeo’, and from which mitochondrial (cox1) and plastid (rbcL) data were obtained. A second species, Corallina elongata Ellis et Solander (type locality Cornwall, England), was shown previously to include at least two species based on DNA sequences. The lectotype of C. elongata is an illustration and therefore an epitype was selected to provide molecular sequence data, using the same markers as for C. officinalis. These molecular sequences for C. officinalis and C. elongata are compared with those of a third, recently described species from Great Britain, Corallina caespitosa R.H. Walker, J. Brodie et L.M. Irvine: these data provide an example for studying Corallina species taxonomy and diversity in other parts of the world. The implications of this work are discussed in relation to concepts of species distribution.
