Ira gave a talk on the genomics of non-model organisms at the UQ Winter School in Mathematical and Computational Biology. It was great to be given an opportunity to talk about some of my favourite topics and meet a bunch of talented bioinformaticians. Hats off to the organisers of this fantastic annual event including Nick Hamilton (Dr. Nick) who took this photo of me.
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!
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!
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!
Well done to PhD student Sally Lau who won an Antarctic Science International Bursary!
The bursary will help Sally to extend her PhD work on understanding how seascape dynamics structures octopus genetic variation in the Scotia Sea, Southern Ocean.

Laura sequenced the barcoding gene, Cytochrome oxidase I (COI), from palinurid and scyllarid lobster larvae (phyllosoma) caught off the east coast of Australia. She detected two tropical and one subtropical palinurid species ~75–1800 km to the south or southwest of their known species distribution. These results indicate tropical lobster species are reaching temperate regions, providing these species the opportunity to establish in temperate regions if or when environmental conditions become amenable to settlement.

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!

Blue ringed octopus make use of a deadly neurotoxin, TTX (tetrodotoxin) which is also found a wide variety of other animals. In order to do this they must be able to tolerate the toxin themselves, as well as acquire it from the environment or produce it. This paper reviews what we know about the evolution of ttx acquisition in blue ringed octopuses.
Nikeisha J. Caruana , Jan M. Strugnell, Pierre Faou, Julian Finn, and Ira R. Cooke
Nikeisha compared the slime from two bobtail squids and found that their proteomic composition was very similar. She also found several highly abundant, short secreted proteins in the slime, for which a function is unknown.
