Lu and T.N. Stranks Department of Invertebrate Zoology, Museum of Victoria 285-321 Russell Street, Melbourne, Victoria 3000, Australia Abstract Lu, C.C. and Stranks, T.N., 1994. Synopsis of Pareledone and Megaleledone species, with description of two new species from East Antarctica (Cephalopoda: Octopodidae). Memoirs of the Museum of Victoria 54: 221-242. A synopsis is given for species of the genus Pareledone from Prydz Bay, Antarctica: P. adelieana (Berry, 1917), P. cliarcoti (Joubin, 1905), and P. harrissoni (Berry, 1917). Two new species of Pareledone are described and illustrated: P.framensis from Fram Bank, off MacRobertson Land, and P. prydzensis from Prydz Bay, off the Amery Ice Shelf, Antarcti- ca.

Image courtesy of Cromer Museum. 2 The James Caird Society Journal – Number Six March 2012 The Centennial season has arrived. Having celebrated Shackleton’s British Antarctic (Nimrod) Expedition, courtesy of the ‘Matrix Shackleton Centenary Expedition’, in 2008/9, we now turn our attention to the events of 1910/12. This was a period when 3 very extraordinary and ambitious men (Amundsen, Scott and Mawson) headed south, to a mixture of acclaim and tragedy. A little later (in 2014) we will be celebrating Sir Ernest’s ‘crowning glory’ –the Centenary of the Imperial Trans-Antarctic (Endurance) Expedition 1914/17. Shackleton failed in his main objective (to be the first to cross from one side of Antarctica to the other). He even failed to commence his land journey from the Weddell Sea coast to Ross Island. However, the rescue of his entire team from the ice and extreme cold (made possible by the remarkable voyage of the James Caird and the first crossing of South Georgia’s interior) was a remarkable feat and is the reason why most of us revere our polar hero and choose to be members of this Society. For all the alleged shenanigans between Scott and Shackleton, it would be a travesty if ‘Number Six’ failed to honour Captain Scott’s remarkable achievements - in particular, the important geographical and scientific work carried out on the Discovery and Terra Nova expeditions (1901-3 and 1910-12 respectively).

Because Mackintosh had intended to use Aurora as the party's main living quarters, most of the shore party's personal gear, food, equipment and fuel was still aboard when the ship departed. Although the sledging rations intended for Shackleton's depots had been landed, [41] the ten stranded men were left with "only the clothes on their backs". We cannot expect rescue before then, and so we must conserve and economize on what we have, and we must seek and apply what substitutes we can gather". On the last day of August Mackintosh recorded in his diary the work that had been completed during the winter, and ended: "Tomorrow we start for Hut Point". The second season's work was planned in three stages. Nine men in teams of three would undertake the sledging work. The first stage, hauling over the sea ice to Hut Point, started on 1 September , and was completed without mishap by the end of the month. Shortly after the main march to Mount Hope began, on 1 January , the failure of a Primus stove led to three men Cope, Jack and Gaze returning to Cape Evans, [49] where they joined Stevens. The scientist had remained at the base to take weather measurements and watch for the ship.

In an initiative to help further our understanding, invertebrate surveys over the past seven years have now revealed more than 500 species, many of which are endemic. This is an essential reference guide to these species. Illustrated with hundreds of representative photographs, it includes brief narratives on the biology and ecology of the major taxonomic groups and characteristic features of common species. It is primarily aimed at scientifi c observers, and is intended to be used as both a training tool prior to deployment at-sea, and for use in making accurate identifi cations of invertebrate by catch when operating in the HIMI region. Many of the featured organisms are also found throughout the Indian sector of the Southern Ocean, the guide therefore having national appeal.

  • Positive Selection in Octopus Haemocyanin Indicates Functional Links to Temperature Adaptation Michael Oellermann1*, Jan M
    Oellermann et al. BMC Evolutionary Biology (2015) 15:133 DOI 10.1186/s12862-015-0411-4 RESEARCH ARTICLE Open Access Positive selection in octopus haemocyanin indicates functional links to temperature adaptation Michael Oellermann1*, Jan M. Strugnell2, Bernhard Lieb3 and Felix C. Mark1 Abstract Background: Octopods have successfully colonised the world’s oceans from the tropics to the poles. Yet, successful persistence in these habitats has required adaptations of their advanced physiological apparatus to compensate impaired oxygen supply. Their oxygen transporter haemocyanin plays a major role in cold tolerance and accordingly has undergone functional modifications to sustain oxygen release at sub-zero temperatures. However, it remains unknown how molecular properties evolved to explain the observed functional adaptations. We thus aimed to assess whether natural selection affected molecular and structural properties of haemocyanin that explains temperature adaptation in octopods. Results: Analysis of 239 partial sequences of the haemocyanin functional units (FU) f and g of 28 octopod species of polar, temperate, subtropical and tropical origin revealed natural selection was acting primarily on charge properties of surface residues. Polar octopods contained haemocyanins with higher net surface charge due to decreasedglutamicacidcontentandhighernumbersof basic amino acids. Within the analysed partial sequences, positive selection was present at site 2545, positioned between the active copper binding centre and the FU g surface. At this site, methionine was the dominant amino acid in polar octopods and leucine was dominant in tropical octopods. Sites directly involved in oxygen binding or quaternary interactions were highly conserved within the analysed sequence. Conclusions: This study has provided the first insight into molecular and structural mechanisms that have enabled octopods to sustain oxygen supply from polar to tropical conditions.
