Plastic responses in shell morphology and shell growth have been widely studied in gastropods and are often related to environmental calcium availability, which influences shell biomineralisation. To date, all of these studies have overlooked micro-scale structure of the shell, in addition to how it is related to species responses in the context of environmental pressure.

March 2013 ………………………………………. Catharina Wilhelmina Groenewald Copyright © 2013 Stellenbosch University All rights reserved Stellenbosch University http://scholar.sun.ac.za III ABSTRACT Sub-Antarctic Islands are of considerable conservation importance due to their high endemicity and unique ecosystems. Furthermore, the rich geological and glaciological histories of these islands provide a unique platform to study the biodiversity and biogeography of its biota. Sub-Antarctic islands are divided into three biogeographic regions; the South Indian Ocean Province includes the Prince Edward Islands, Îles Kerguelen, Îles Crozet, Heard Island and McDonald Island. One of the taxa that have long fascinated biogeographers and taxonomists alike is the flightless moth, genus Pringleophaga, which is endemic to the Kerguelen, Crozet and Prince Edward Islands. This study addressed three questions relating to the genus Pringleophaga at various spatial and evolutionary scales.

  • Johannes Thiele and His Contributions to Zoology. Part 2. Genus-Group Names (Mollusca)
    NEMOURIA Occasional Papers of the Delaware Museum of Natural History NUMBER 39 SEPTEMBER 30, 1991 JOHANNES THIELE AND HIS CONTRIBUTIONS TO ZOOLOGY. PART 2. GENUS-GROUP NAMES (MOLLUSCA) Kenneth J. Boss 1 and Rudiger Bieler2 ABSTRACT. This is the second part of a series on the German zoologist Johannes Thiele (1860-1935) and comprises a critical listing of the genus-group taxa which he described as new to malacology. Each of these names is accompanied by author and bibliographic references, original status, type-species with its original binominal spelling and bibliographic source and some data on subsequent taxonomic placements. Thiele introduced a total of 291 such names in the Phylum Mollusca, distributed as follows: 11 Aplacophora; 39 Polyplacophora; 200 Gastropoda (138 Prosobranchia; 20 Opisthobranchia and 42 Pulmonata); 31 Bivalvia; 10 Cephalopoda; there were no new scaphopod or monoplacophoran names. Of these, later authors recognized as valid 85 at the generic level, 110 at the subgeneric level; 71 are considered to be synonyms, and the remaining 25 are unjustified emendations or errors. INTRODUCTION As part of a series on the scientific contributions of Johannes Thiele, the eminent German zoologist, we provide here an alphabetical listing and analysis of all the genus-group taxa introduced by him in his publications on mollusks as delineated by Bieler & Boss (1989). A total of 291 names is included in the following format: (1) genus-group name; (2) author(s); (3) year of publication; (4) condensed bibliographic reference; (5) original status as given by Thiele; (6) subsequent status 1Museum of Comparative Zoology, Harvard University, Serial Publication Cambridge, Massachussetts 02138, U.S.A.

IAL President Since the inaugural IAL meeting in Münster in March 1986, our society has had tremendously successful and enjoyable meetings. I still remember the first meeting when, for the first time, I met a number of prestigious colleagues and – as an The 8 undergraduate student – could interact with colleagues in a relaxed atmosphere. These meetings are especially vital for th students and early career scientists where they can interact – Lichens in Deep Time IAL Symposium with colleagues and build networks. Older scientists, like myself, can pass on essential guidance to younger scholars, while at the same time also learn from their new and bright ideas. We are confident that this 8th Symposium in Helsinki will be equally as memorable as the previous ones. Helsinki has a rich history and tradition in lichenological research and we are looking forward to this event, entitled ”Lichens in Deep Time”. Contributions to the symposium will reflect the latest trends in using genomic data to better understand the lichen symbiosis and the evolutionary history of its partners, have a strong part in ecological studies, address the threats imposed by rapid man-made changes occurring to the biosphere and an ever-growing interest in tropical lichens.

PUGH1 and R.I. LEWIS SMITH2 1Department of Life Sciences, Anglia Ruskin University, East Road, Cambridge CB1 1PT, UK 2Centre for Antarctic Plant Ecology and Diversity, Alton Road, Moffat DG10 9LB, UK [email protected] Abstract: Multivariate analysis shows that shells of Notodiscus sp. (Charopidae: Pulmonata) reported from South Georgia are smaller and proportionately taller than, but otherwise similar to, populations of Notodiscus hookeri (Reeve) from Iles Crozet and Iles Kerguelen. The origin of this solitary, and spatially limited, South Georgia population is enigmatic. It is confined to a remarkably small coastal lowland site which was glaciated at Last Glacial Maximum, precluding a Tertiary relict origin, and on the leeward north-east coast, ruling out post- glacial ocean rafting. The site is close to the King Edward Point settlement, yet the absence of any logistics connections with the Iles Crozet or Iles Kerguelen mitigates against anthropogenic introduction. The close proximity of the population to nests of blue-eyed shag (Phalacrocorax atriceps), Dominican gull (Larus dominicanus) and light-mantled sooty albatross (Phoebetria palpebrata) could imply the snail was originally introduced to South Georgia via these ocean transiting seabirds.

  • Introduction 2 BIODIVERSITÉ ET CONSERVATION EN OUTRE-MER 3
    BIODIVERSITÉ ET CONSERVATION EN OUTRE-MER 1 Avant-propos Consacrée au Sommet de la Terre en 1992, la biodiversité représente l’extraordinaire variété du vivant sur notre planète, des gènes aux espèces jusqu’aux écosystèmes. Elle joue un rôle fondamental dans le fonctionnement des systèmes naturels qui fournissent de multiples biens et services à l’humanité. Sa dégradation a cependant atteint une ampleur sans précédent sous l’effet des activités humaines. Les listes rouges de l’UICN montrent que 5 435 espèces animales (24% des mammifères, 12 % des oiseaux, 25 % des reptiles, 20 % des amphibiens et 30 % des poissons d’eau douce) et près de 34 000 espèces végétales, soit plus d’une plante sur huit, sont actuellement menacées dans le monde. Le taux d’extinction actuel des espèces est environ 1 000 fois supérieur au taux d’extinction naturel. En ratifiant la Convention sur la diversité biologique, les États se sont engagés à prendre des mesures pour la conservation de la biodiversité, l’utilisation durable de ses éléments, ainsi que le partage juste et équitable des avantages découlant de l’exploitation des ressources génétiques. Le Comité français pour l’UICN tenait à mettre en évidence l’importance mondiale du patrimoine biologique des collectivités françaises d’outre-mer, qui confère à la France des responsabilités importantes pour répondre à ses engagements vis à vis de la Convention. Ces richesses naturelles sont menacées et doivent donc faire l’objet d’actions ambitieuses, à la hauteur des enjeux présents dans ces territoires. Cette biodiversité est d’autant plus précieuse qu’elle offre des possibilités importantes de développement économique et social, pour autant que sa conservation soit pleinement intégrée et assurée.

The present work examines Shell morphometrics; the phylogenetic relationships of two populations of this land snail from Egypt and Saudi Arabia Molecular phylogeny; using mitochondrial markers (partial 16S rDNA and COI gene sequencing) in addition to tradi- 16S rDNA; tional methods of shell’s shape analysis. The study highlights the extraordinary morphological vari- COI ations between the two studied snail populations. This variation seems to be related to the geographic origin but not the colouration of the shell and may have caused the present changes in their mitochondrial genes. The molecular phylogenetic analysis of partial 16S rDNA and COI gene segments confirms the morphological findings. The two monophyletic populations of Egyptian and Saudi Arabian E. vermiculata were found to represent two distinct groups. The concordance of morphological and molecular results, that produced very clear separation of both populations, leads us to conclude that the two separate groups could be considered two separate subspecies.
