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. -

Bag X17 Bellville 7535 South Africa * Correcsponding author: [email protected] Key words: encrusting coralline algae, diet, grazers, herbivory, organic content, rocky shore. Abstract Kalk Bay, South Africa, has a typical south coast zonation pattern with a band of seaweed dominating the mid-eulittoral and sandwiched between two molluscan- herbivore dominated upper and lower eulittoral zones. Encrusting coralline algae were very obvious features of these zones. The most abundant herbivores in the upper eulittoral were the limpet, Cymbula oculus (10.4 + 1.6 m-2; 201.65 + 32.68 g.m-2) and the false limpet, Siphonaria capensis (97.07 + 19.92 m-2; 77.93 + 16.02 g.m-2). The territorial gardening limpet, Scutellastra cochlear, dominated the lower eulittoral zone, achieving very high densities (545.27 + 84.35 m-2) and biomass (4630.17 + 556.13 g.m-2), and excluded all other herbivores and most seaweeds, except for its garden alga and the encrusting coralline alga, Spongities yendoi (35.93 + 2.26 % cover). For the upper eulittoral zone, only the chiton Acanthochiton garnoti 30.5 + 1.33 % and the limpet C. -

This thesis is my own work: Leesha Richardson RCHLEE003 Date: 8 February 2020 i Abstract Seals were a major dietary item for coastal hunter-gatherers and herders in South Africa. At Nelson Bay Cave (NBC), more than half of the Holocene mammal bones are from Cape Fur seals (Arctocephalus pusillus). Previous analyses of the seal assemblage from this site have studied only selected skeletal elements. This study is the first comprehensive analysis of seal remains from selected archaeological levels at Nelson Bay Cave and from the 2007/2008 excavations at nearby Hoffmans/Robberg Cave (HRC). Body part representation and frequency, age distribution and bone modification have been documented to determine the role of seals in the lifeways of hunter-gatherers and pastoralists at Robberg throughout the Holocene. -

These encrusting coralline red seaweeds are widespread in shallow water in all of the world’s oceans, where they often cover close to 100% of rocky substrates. Nowhere are they more important than in the ecology of coral reefs.

The Reinvestigation of Hoffman'sirobberg Cave - the Artefactual and Shellfish Assemblages, 2007
THE REINVESTIGATION OF HOFFMAN'SIROBBERG CAVE - THE ARTEFACTUAL AND SHELLFISH ASSEMBLAGES, 2007 KATHARINE KYRIACOU Thesis presented for the degree of Master of Philosophy In the Department of Archaeology University of Cape Town February 2009 Abstract This thesis documents the re-investigation of Hoffman' slRobberg Cave, a little known site located on the Robberg Peninsula near Plettenberg Bay on the southern Cape coast of South Africa Previous excavations carried out at the site early in the twentieth century and again in the late 1950s are scantily documented. Furthermore, a large collection derived from Hoffinan' s excavations, which I examined and catalogued in 2006, is only a selective sample of the archaeological remains from the site. Small-scale excavations were carried out at Hoffinan'slRobberg Cave in June/July 2007 with the dual objectives of documenting the stratigraphy of the Late Holocene deposits, and obtaining an unselected sample of material for analysis. The primary aim was to elucidate the lifeways of prehistoric hunter-gatherers living at the site for a short period during the Later Stone Age. The stratigraphy and chronology of the deposits indicate two episodes of occupation between 4000 and 3300 BP. Shellfish residues suggest exploitation patterns in keeping with the steep topography of the shore in the immediate vicinity of the cave. Changes in the size distributions of the most abundant limpet species, S. cochlear, are attributed to fluctuations in the intensity of human predation. A comparative sample from an open midden in Noetzie, Knysna, reflects slightly different exploitation patterns, as well as chronological changes in shellfish collection strategies which have been documented elsewhere. -
Excavations at Blombos Cave and the Blombosfontein Nature Reserve
HOLOCENE PREHISTORY OF THE SOUTHERN CAPE, SOUTH AFRICA: EXCAVATIONS AT BLOMBOS CAVE AND THE BLOMBOSFONTEIN NATURE RESERVE Christopher Stuart Henshilwood Institute for Human Evolution University of the Witwatersrand, Johannesburg, South Africa & Institute for Archaeology, History, Culture and Religion University of Bergen, Bergen, Norway 1 PREFACE During 1992/3 nine Later Stone Age (LSA) coastal midden sites ranging in age from 6960 B.P. to 290 B.P., and representing 28 depositional units were excavated in the Blombosfontein Nature Reserve and in the directly adjacent Blombos Estates, situated 20 km to the west of Still Bay, southern Cape, South Africa (Figs. 1.1). This research formed the core of the authors doctoral thesis ‘Holocene archaeology of the coastal Garcia State Forest, southern Cape, South Africa’ completed at Cambridge University in 1995 (Henshilwood 1995). This monograph is based on the results derived from this research. Additional data derived from the 1997 – 1999 excavations of the Later Stone Age levels at Blombos Cave (BBC) has been added into the text (also see appendix) and a brief review of the results from the 1997 – 2005 excavations of the Middle Stone Age (MSA) levels is included. In this monograph the term Blombosfontein is used to cover both the Blombosfontein Nature Reserve and the Blombos Estates. On some older topographical maps the area is designated Garcia State Forest but the currently accepted name is Blombosfontein (lit. flower bush spring). The sites excavated were originally numbered from 1 – 9 and given the acronym GSF (Henshilwood 1995). In this monograph the acronym has been changed to BBF (for Blombosfontein); BBF 1 is the oldest and BBF 9 the youngest site (Fig. -

Population Dynamics of the Limpet Scutellastra Laticostata on Rocky Shores in Western Australia
Vol. 646: 79–92, 2020 MARINE ECOLOGY PROGRESS SERIES Published July 30 https://doi.org/10.3354/meps13364 Mar Ecol Prog Ser Persistence of giants: population dynamics of the limpet Scutellastra laticostata on rocky shores in Western Australia Robert E. Scheibling1,*,#, Robert Black2,# 1Department of Biology, Dalhousie University, Halifax, NS B3H 4R2, Canada 2School of Biological Sciences, University of Western Australia, Crawley, WA 6009, Australia ABSTRACT: Population dynamics and life history traits of the ‘giant’ limpet Scutellastra laticostata on intertidal limestone platforms at Rottnest Island, Western Australia, were recorded by interan- nual (January/February) monitoring of limpet density and size structure, and relocation of marked individuals, at 3 locations over periods of 13−16 yr between 1993 and 2020. Limpet densities ranged from 4 to 9 ind. m−2 on wave-swept seaward margins of platforms at 2 locations and on a rocky notch at the landward margin of the platform at a third. Juvenile recruits (25−55 mm shell length) were present each year, usually at low densities (<1 m−2), but localized pulses of recruit- ment occurred in some years. Annual survival rates of marked limpets varied among sites and cohorts, ranging from 0.42 yr−1 at the notch to 0.79 and 0.87 yr−1 on the platforms. A mass mortality of limpets on the platforms occurred in 2003, likely mediated by thermal stress during daytime low tides, coincident with high air temperatures and calm seas. Juveniles grew rapidly to adult size within 2 yr. Asymptotic size (L∞, von Bertalanffy growth model) ranged from 89 to 97 mm, and maximum size from 100 to 113 mm, on platforms. -

Maneveldt a, , Y.M. Chamberlain b, D.W. Keats a a Department of Biodiversity & Conservation Biology, University of the Western Cape, Private Bag X17, Bellville 7535, South Africa b Institute of Marine Sciences, University of Portsmouth, Ferry Road, Portsmouth, PO4 9LY, UK Received 15 May 2007; received in revised form 14 December 2007; accepted 4 February 2008 Abstract Non-geniculate coralline red algae are common in all of the world's oceans, where they often occupy close to 100% of the primary rocky substratum. The South African rocky subtidal and intertidal habitats in particular, are rich in diversity and abundance of non-geniculate coralline red algae. Despite their ubiquity, they are a poorly known and poorly understood group of marine organisms. Few scattered records of non- geniculate coralline red algae were published prior to 1993, but these should be treated with caution since many taxa have undergone major taxonomic review since then. Also, generic names such as Lithophyllum and Lithothamnion were loosely used by many authors for a host of different non-geniculate coralline algae. A series of taxonomic studies, based mainly on the Western Cape Province of South Africa, published particularly between 1993 and 2000, has significantly extended our knowledge of these algae from southern Africa. References to these latter papers and the older records are now gathered here and a list of the well delimited families (3), subfamilies (4), genera (17) and species (43) are presented.
