Welcome to Greg Maes

Christine Dudgeon (right), Jenny Ovenden (centre) are pleased to host a visit by Dr Gregory Maes (KU Leuven – JCU). Greg gave an interesting seminar yesterday “Application of genomic tools to inform conservation and management of the Galapagos shark  (Carcharhinus galapagensis)”, which stimulated lots of discussion about genomics and genetics of elasmobranch species from Australia and […]

World pays attention to research on shark reproduction

The recent article on switch from sexual to asexual reproduction in zebra sharks has achieved a high altimetric attention score. It was in the top 5% of all research outputs ever tracked by Altimetrics. Christine Dudgeon’s achievement shows that workers who divide their time between science and family duties can make important contributions to both. Photo: Chris and […]

Shark mother produces pups with mate then without.

Published today, Christine Dudgeon’s new paper shows that a female Stegastoma fasciatum (leopard, zebra shark) alternated between sexual and asexual reproduction in the Townsville aquarium. In the absence of her mate, genotyping confirmed a batch of pups were not the result of sperm storage and sexual reproduction as expected. Three juvenile sharks were homozygous for maternal alleles […]

Doing science with the community

MFL associate, Christine Dudgeon, attended the inaugural Citizen Science conference in Canberra on 23-24 July 2015. Citizen science is the collaboration between members of the public and scientists to design research projects and collect and analyse the data. At present, Chris is working with Jenny and colleagues at MFL on the genetic stock structure of three inshore fish species […]

A link found between DNA and abundance for sharks in Queensland

At the MFL, we are keen to develop genetic methods for assessing abundance of fisheries populations. One method being explored is genetic effective population size. We are focusing on shark and ray populations, because they are generally less abundant than species like finfish and shellfish and the math is easier. A new study that was published today […]
