An Analysis of the Community Composition of the Xiphophora Gladiata Dominated Subzone of the Tasmanian Sublittoral Fringe
Papers and Proceedings ol the Royal Society of Tasmania, Volume 123, 1989 191 AN ANALYSIS OF THE COMMUNITY COMPOSITION OF THE XIPHOPHORA GLADIATA DOMINATED SUBZONE OF THE TASMANIAN SUBLITTORAL FRINGE by E. L. Rice (with five tables and nine text-figures) RICE, E.L., 1989 (31:x): An analysis of the community composition of the Xiphophora iladiata dominated subzone of the Tasmanian sublittoral fringe. Pap. Proc. R. Soc. Tasm. 123: I 91-209. https://doi.org/10.26749/rstpp.123.191 ISSN 0080-4703. Biological Sciences Branch, Department of Fisheries and Oceans, Halifax Research Laboratory, PO Box 550, Halifax, Nova Scotia B3J 2S7, Canada; formerly Department of Botany, University of Tasmania The rocky shore sublittoral fringe of the oceanic coasts of Tasmania contains a subzone dominated by the large brown alga Xiphophora iladiata. The community composition of this subzone is here examined at fourteen sites. The phytal and fauna! assemblages are analysed by principal co-ordinate, classification and nodal analyses. This subzone is found to have a high species richness. including species which had been thought to occupy only higher or lower tidal levels. It is suggested that both plant and animal assemblages are strongly influenced by wave exposure, freshwater run-off and geography. Key Words: marine community composition, sublittoral fringe, Xiphophora, multivariate analyses. INTRODUCTION (Bennett & Pope 1960). Thus, on the oceanic coasts of Tasmania it is possible to define a Xiphophora The rocky shores of southeastern Australia are subzone, dominated by X. g/adiata, which marks known to be occupied primarily by barnacles and the highest limit of the sublittoral fringe on very molluscs in the upper intertidal (Underwood 1981), exposed shores and represents the upper sublittoral while algae dominate at midshore level and below. -

No. 9792 9163 ADDRESS: 6 Southdean Street, Dandenong, Vic. 3175 Conus marmoreus Linne EMAIL: [email protected] VIC. BR. BULL. NO. 269 JUNE/JULY 2013 NOTICE OF MEETING The next meeting of the Branch will be held on the 17th June at the Melbourne Camera Club Building, cnr. Dorcas & Ferrars Sts South Melbourne at 8pm. This will be a Member’s night. Raffles & Supper as usual. There will be no meeting in July. A Bulletin will be issued prior to the August meeting which will be held on the 19th. At the April meeting we welcomed Caitlin Woods, PR Officer for the Malacological Society of Australasia. We discussed with her our role in the society and she offered any assistance she could to promote our branch to further the study of molluscs in Victoria. Jack Austin advises, with considerable regret, that he must dispose of his shell collection as his intended successor-grandson has opted for a volunteer career overseas and will not have a house in Australia for some years. Jack is a part-sponsor of this venture and will sell-off what he can of the collection to raise funds for his grandson. The collection is fairly extensive world-wide, about 7,000 lots, emphasising GBR, SE Australia, NT, Pacific lslands. All lots are registered - lists of families or places can be supplied.

Mass Spectrometry Imaging Reveals New Biological Roles for Choline
www.nature.com/scientificreports OPEN Mass spectrometry imaging reveals new biological roles for choline esters and Tyrian purple precursors Received: 17 March 2015 Accepted: 27 July 2015 in muricid molluscs Published: 01 September 2015 David Rudd1, Maurizio Ronci2,3, Martin R. Johnston4, Taryn Guinan2, Nicolas H. Voelcker2 & Kirsten Benkendorff5 Despite significant advances in chemical ecology, the biodistribution, temporal changes and ecological function of most marine secondary metabolites remain unknown. One such example is the association between choline esters and Tyrian purple precursors in muricid molluscs. Mass spectrometry imaging (MSI) on nano-structured surfaces has emerged as a sophisticated platform for spatial analysis of low molecular mass metabolites in heterogeneous tissues, ideal for low abundant secondary metabolites. Here we applied desorption-ionisation on porous silicon (DIOS) to examine in situ changes in biodistribution over the reproductive cycle. DIOS-MSI showed muscle-relaxing choline ester murexine to co-localise with tyrindoxyl sulfate in the biosynthetic hypobranchial glands. But during egg-laying, murexine was transferred to the capsule gland, and then to the egg capsules, where chemical ripening resulted in Tyrian purple formation. Murexine was found to tranquilise the larvae and may relax the reproductive tract. This study shows that DIOS-MSI is a powerful tool that can provide new insights into marine chemo-ecology. Secondary metabolites are known to chemically mediate intra- and interspecies interactions between organisms1. In molluscs, secondary metabolites have been detected and identified during mate attraction2, defence3,4, predatory behaviour5, anti-fouling6,7 and reproduction8. The importance of understanding the mechanisms behind these chemical interactions within a species cannot be underestimated, particularly when specific secondary metabolites impart a competitive advantage. -

Molluscs of the Intertidal Zone
Molluscs of the intertidal zone- Hanging on for dear life … Madeline Ovens … Line drawings courtesy of Parks Victoria Next time you visit a rock platform along the Victorian coast, spare a thought for those creatures doing it tough in this testing environment. Imagine living and surviving in a place that is subjected to two droughts and two floods, daily! Such is the life of a myriad of plants and animals that call the intertidal zone ‘home’. One such group of animals, the Molluscs, are well adapted to this lifestyle, and as a result are commonly found on the rocky shores and reefs of Victoria. Over 120,000 species of mollusc are known to inhabit the waters surrounding Australia, but here are some you are likely to come across in our local area. Chiton class Polyplacophora Chitons are a fascinating animals that resembles the common slater, although they are more closely related to a garden snail. Fossil records place their origins at over 400 million years ago. They can be found hiding in crevices and under rocks in the mid-lower intertidal zone. Chitons are more active after dusk than during the day, and will move quickly to evade light, if exposed by an upturned rock. Size varies from that of your fingernail to that of your palm, and colour can differ between individuals. However, all are distinguished by armour of eight overlapping plates covering their body, allowing increased flexibility. Individual plates can be found washed into rock pools among the shells and sand. Common species include Green/ Southern Chiton Ischnochiton australis and Giant Chiton Plaxiphora albida. -
Do Singapore's Seawalls Host Non-Native Marine Molluscs?

If urbanisation is accompanied by a concomitant increase in shipping then this may also be a factor, i.e. increased propagule pressure of non-native species due to translocation beyond their native range via the hulls of ships and/or in ballast water. Singapore is potentially highly vulnerable to invasion by non-native marine species as its coastline comprises over 60% seawall and it is one of the world’s busiest ports. The aim of this study is to investigate the native, non-native, and cryptogenic molluscs found on Singapore’s seawalls. -
