Quantitative Proteomic Analysis of the Slime and Ventral Mantle Glands of the Striped Pyjama Squid (Sepioloidea lineolata)

New paper in Journal of Proteome Research by group alumnus, Nikeisha Caruana uses quantitative proteomics to understand slime secretions in striped pyjama squid. For this work Nikeisha used a multi-tissue comparison to hone in proteins unique to slime-producing glands. The work is also the first time these glands have been described in detail and their proteomic similarity to the slime and physical structure implicates them as likely secretion structures.

Abalone sampling at Southern Ocean Mariculture

Jan and Phoebe visited Southern Ocean Mariculture (SOM) in Port Fairy, Victoria at the start of July to collect samples for Phoebe’s honours project. Phoebes project, supported by the Fisheries Research and Development Corporation and the Australian Abalone Growers Association, seeks to test established methods of early prediction of genetic merit in abalone broodstock. It was freezing in Port Fairy in comparison to sunny Townsville, but great to see the abalone growth and the impressive technology and set up at SOM! Thanks for hosting us!

Abalone = Yum!

8th International Barcode of Life Conference

Jan gave a plenary lecture at the 8th International Barcode of Life Conference in Trondheim, Norway on June 19. Jan spoke about “Dating the West Antarctic ice sheet collapse using molecular sequence data.” The conference was great – loads of metabarcoding presentations including monitoring freshwater and marine environments and also using barcoding to ascertain the ingredients in foods. Great to catch up with old friends and make new ones and see a little bit of beautiful Norway!

Exciting genetics and glaciology collaboration underway!

Last week Sally and Jan, together with Nerida Wilson from Western Australian Museum, visited our collaborators Prof Tim Naish and A/Prof Nick Golledge at the Antarctic Research Centre, Victoria University of Wellington, in New Zealand to discuss about how the past Antarctic Ice Sheet configurations influenced population genetics in the Southern Ocean. We aim to combine genetics and glaciology to reconstruct the past collapses of West Antarctic Ice sheet. Watch this space!

During our trip to New Zealand we also took the opportunity to visit the National Institute of Water and Atmospheric Research (NIWA) in Wellington to sample benthic critters for our Southern Ocean genetics projects. With a wealth of Antarctic biodiversity preserved, this collection is like a treasure box to us! Thank you Sadie Smith for hosting us!

SEMINAR “Antarctica and its evolution: rising sea levels”

Jan's talk
Jan in front of S.E.A aquarium

Last night (Sat 2nd March 2019), Jan gave a seminar at the spectacular S.E.A. Aquarium in Singapore.  The title of the seminar was “Antarctica and its evolution: rising sea levels”.  The stage of the seminar was at the front of the biggest aquarium in the complex containing loads of fish and manta rays – a really wonderful backdrop!
