Saltmarsh and Samphire
Baker, J. L. (2015) Marine Assets of Yorke Peninsula. Volume 2 of report for Natural Resources - Northern and Yorke, South Australia 6. Saltmarsh and Samphire © A. Brown Figure 6.1: Saltmarsh with samphire, in NY NRM Region. (A) Point Davenport; (B) Winninowie Conservation Park. Photos (c) A. Brown. (B): (c) Google Earth. Asset Saltmarsh and Samphire Description Areas of saline, mineral-rich, organic-rich, and low oxygen coastal soils within and above high tide level, often fronted by mangroves, and backed by saltbush shrubland. Saltmarsh supports various salt-tolerant plants, with samphires being the most common and significant in terms of cover in South Australia. There are distinct assemblages of salt-tolerant invertebrates associated with saltmarsh habitats. Saltmarshes provide habitat for fishes, including juveniles of species which utilise other marine habitats, and are an important feeding area for various bird species, including migratory shore birds. Examples of Birds Main Species Cormorant species (e.g.; Pied, Little Pied, and Black-faced) Caspian Tern and Little Tern Pied Oystercatcher and Sooty Oystercatcher Black-winged Stilt, Banded Stilt, Great Egret, White-faced Heron, Little Egret the threatened species Hooded Plover Little Stint Red-capped Plover Slender-billed Thornbill (Samphire Thornbill) Rock Parrot The raptors Eastern Osprey and White-bellied Sea Eagle Migratory shorebirds listed under international treaties, such as Bar-tailed Godwit, Curlew Sandpiper and Sharp-tailed Sandpiper, Red-necked Stint, Grey Plover , Red Knot, Common Greenshank, Ruddy Turnstones Bony Fishes juvenile Yelloweye Mullet juvenile Greenback Flounder juvenile Southern Blue-spotted Flathead Western Striped Grunter Congolli Glass Goby Small-mouthed Hardyhead Silver Fish Smooth Toadfish Goby species such as Blue-spotted Goby and Southern Longfin Goby Adelaide Weedfish Baker, J. -

PHYLOGENY AND HISTORICAL BIOGEOGRAPHY OF LIMPETS OF THE ORDER PATELLOGASTROPODA BASED ON MITOCHONDRIAL DNA SEQUENCES TOMOYUKI NAKANO AND TOMOWO OZAWA Department of Earth and Planetary Sciences, Nagoya University, Nagoya 464-8602,Japan (Received 29 March 2003; accepted 6June 2003) ABSTRACT Using new and previously published sequences of two mitochondrial genes (fragments of 12S and 16S ribosomal RNA; total 700 sites), we constructed a molecular phylogeny for 86 extant species, covering a major part of the order Patellogastropoda. There were 35 lottiid, one acmaeid, five nacellid and two patellid species from the western and northern Pacific; and 34 patellid, six nacellid and three lottiid species from the Atlantic, southern Africa, Antarctica and Australia. Emarginula foveolata fujitai (Fissurellidae) was used as the outgroup. In the resulting phylogenetic trees, the species fall into two major clades with high bootstrap support, designated here as (A) a clade of southern Tethyan origin consisting of superfamily Patelloidea and (B) a clade of tropical Tethyan origin consisting of the Acmaeoidea. Clades A and B were further divided into three and six subclades, respectively, which correspond with geographical distributions of species in the following genus or genera: (AÍ) north eastern Atlantic (Patella ); (A2) southern Africa and Australasia ( Scutellastra , Cymbula-and Helcion)', (A3) Antarctic, western Pacific, Australasia ( Nacella and Cellana); (BÍ) western to northwestern Pacific (.Patelloida); (B2) northern Pacific and northeastern Atlantic ( Lottia); (B3) northern Pacific (Lottia and Yayoiacmea); (B4) northwestern Pacific ( Nipponacmea); (B5) northern Pacific (Acmaea-’ânà Niveotectura) and (B6) northeastern Atlantic ( Tectura). Approximate divergence times were estimated using geo logical events and the fossil record to determine a reference date. -

NMMU has a long tradition of marine COSTANZA has an H-index above 100 and >60 000 research and its institutional marine and maritime strategy is coming to citations. His area of specialisation is ecosystem goods fruition, which makes this an ideal time for us to host this triennial meeting. and services and ecological economics. Costanza’s Under the auspices of SANCOR, this is the second time we host SAMSS in PE and the transdisciplinary research integrates the study of theme ‘Embracing the blue – unlocking the ocean’s potential whilst maintaining social humans and nature to address research, policy, and and ecological resilience’ is highly topical and appropriate, aligning with Operation management issues. His work has focused on the Phakisa, which is the national approach to developing a blue economy. South Africa is interface between ecological and economic systems, at a cross roads and facing economic challenges. Economic growth and lifting people particularly at larger temporal and spatial scales, from out of poverty is a priority and those of us in the ‘marine’ community need to be part small watersheds to the global system. -

The spatial ecology of Albula glossodonta in the St. Joseph Atoll, Seychelles A thesis submitted in fulfilment of the requirements for the degree of MASTER OF SCIENCE of RHODES UNIVERSITY By Emily Jeanne Moxham February 2017 Abstract Abstract Bonefish (Albula spp.) support valuable recreational and artisanal fisheries worldwide. Declining stocks have been reported at multiple localities, potentially jeopardising numerous multimillion-dollar industries. In particular, tourism generated through bonefish fly fishing contributes considerably to the economies of many isolated tropical islands and atolls. However, despite their economic value, little is known about bonefish in the Indian Ocean. This study aimed to contribute to the understanding of bonefish ecology in the Indian Ocean by (1) reviewing the bonefish literature to identify knowledge gaps; (2) evaluating the post release survival of acoustically tagged bonefish and; (3) quantifying the spatial and temporal movements of bonefish at a near-pristine and predator rich atoll in the Seychelles. A review of published literature on bonefish indicated that despite considerable biological and ecological research in the Pacific and Atlantic oceans, virtually no research has been conducted in the Indian Ocean. To help address this research gap, an acoustic telemetry study was initiated at the remote St. Joseph Atoll, within an existing array of 88 automated data logging acoustic receivers. Thirty Albula glossodonta were surgically implanted with Vemco V13 acoustic transmitters in May 2015 and tracked for a period of one year. Only 10% of the tagged bonefish were detected for more than two weeks. A comparison of the final 100 hours of movement data from fish that were detected for less than two weeks to fish detected for longer periods revealed distinct differences. -

Considering that marine environments support a vast global biodiversity and provide a 16 variety of ecosystem functions and services, monitoring of the coastal and intertidal water pH 17 assumes obvious significance. Because current monitoring approaches using meters and loggers 18 are typically limited in application in heterogeneous environments and are financially prohibitive, 19 we sought to evaluate an approach to acidification biomonitoring using living gastropod shells. We 20 investigated snail populations exposed naturally to corrosive water in Brunei (Borneo, South East 21 Asia). We show that surface erosion features of shells are generally more sensitive to acidic water 22 exposure than other attributes (shell mass) in a study of rocky-shore snail populations (Nerita 23 chamaeleon) exposed to greater or lesser coastal geochemical acidification (acid sulphate soil 24 seepage, ASS), by virtue of their spatial separation. -

I further declare that I am confident in the results of the studies undertaken and conclusions drawn as a result of it - as is described in my atl Full Name: Professor Charles Qualif ication(s): PhD Experience (years/ months) : 35 Years EXECUTIVE SUMMARY This specialist study was undertaken to assess the possible impacts of a 4 000 MW capacity power station on the marine environment at one of three potential sites along the Eastern and Western Cape coasts. Such a development at Duynefontein, Bantamsklip or Thyspunt will have a variety of potential impacts. These include: • Disruption of surrounding marine habitats. When associated with the construction of the cooling water intake and outfall system, this effect will be focused within the construction phase and will be localised, of medium duration and significance . -
