Bonnie's latest genetic study suggests that tiger sharks in the Indo-pacific move and interbreed within the region. The study shows that nations in the region need to cooperate to jointly manage and conserve this shared population. Photo: Jenny Ovenden (left) and Bonnie Holmes (right).

Project tiger has been upgraded! Collaborative research on historical collections of jaws in 2015 was the basis for the scaling up of the project to include new species (white sharks). The project is now an international collaboration of Australian and Danish population genomics and elasmobranch experts. It is funded by research councils from those nations. Thanks to Carlos Bustamante for the new project logo.
Hi my name is Danielle Davenport and I am from Gippsland in country Victoria, Australia. I have recently joined the Molecular Fisheries Laboratory (MFL) as a new PhD student under the supervision of Jennifer Ovenden. Prior to joining the MFL, I completed my undergraduate studies in the marine environment at the University of Tasmania and worked for a time in the aquaculture industry. I recently completed my masters degree in Bioinformatics at the University of Queensland where I became interested in using bioinformatic tools and genetic research to inform conservation and management of marine fisheries. The PhD project with the MFL is one part of a larger collaboration between UQ and the Danish Technical University. The project aims to understand the structure and demographies of white shark populations over time using historical (jaws, bones) and contemporary white shark samples.
[caption id="attachment_1704" align="alignleft" width="169"] Alice Manuzzi, Danish Technical University and University of Queesland joint PhD student, January 2017[/caption] I am Alice Manuzzi, I am from Terni, a small city in the central region of Italy. I am starting as a PhD student in population genetics at DTU Aqua under the supervision of Einar Eg Nielsen. I concluded my Master’s degree in Marine Biology at the University of Padua (Italy) in March 2016, with a thesis about the population genomics of a coastal benthic shark, the small-spotted catshark (Scyliorhinus canicula) in the North East Atlantic. The project was developed under the supervision of Dr. Ana Veríssimo at CIBIO, Research Centre in Biodiversity and Genetic Resources (Portugal), where I also worked as a lab technician for few months after the conclusion of my master degree. My core interest is the application of genetic tools for fisheries management purposes. To date most of my studies have been focused on sharks which is in line with the PhD project on tigershark (Galeocerdo cuvier). The aims are to evaluate the historical population changes for the tiger shark, in term of distribution, abundance and evolutionary response to environmental changes and exploitation. We will apply a genomic approach (exome capture and sequencing) on both contemporary and archived (old jaws and bones) specimens of tiger sharks. Mit navn er Alice Manuzzi og jeg kommer fra Terni, en by i den centrale del af Italien, tæt på Rom. Jeg starter som ph.d. student i populations-genetik med Einar Eg Nielsen som vejleder. Jeg færdiggjorde mit speciale i Marin Biologi ved Universitetet i Padova i Marts 2016. Mit speciale handlede om populations genomik hos småplettet rødhaj i Nordøst Atlanten. Projektet var udviklet i samarbejde med Dr. Ana Veríssimo at CIBIO, Research Centre in Biodiversity and Genetic Resources (Portugal), hvor jeg har arbejdet siden som laborant. Min hovedinteresse er anvendelse af genetiske metoder i fiskeriforvaltning. Indtil nu har de mine studier været fokuseret på hajer, hvilket passer rigtig godt med mit ph.d. projekt på tigerhaj (Galeocerdo cuvier). Formålet med projektet er at evaluere historiske populationsændringer i forhold til fordeling, antal og evolutionære respons på miljøændringer og fiskeri. Vi vil anvende de nyeste genomiske metoder (exome capture and sequencing) på både nutidigt og historisk materiale – gamle ben og kæber fra tigerhajer.
Thanks to the Brisbane Times for an accurate summary of a new project starting at MFL in Jan 2017 funded by the Australian Research Council. The project will use detailed genomic analyses on living and long-dead tiger and white sharks to provide new information about the spatial and temporal dimensions of populations to inform conservation and management. Its a collaborative effort between UQ (Mike Bennett, Carlos Bustamante and Jenny Ovenden), Flinders University (Charlie Huveneers) and the Danish Technical University (Einar Nielsen and team).

If you are looking for a world-beating PhD project, here it is! Einar Nielsen in Denmark is looking for applicants to work on a collaborative project on the population genetics of Tiger and White sharks. It follows on from a recently published study that Einar led during his 2015 visit to MFL. Download the details about the PhD position here.
Congratulations to Safia Maher who has completed her BSc Hons project on tiger shark genetics at MFL. Safia gave a seminar at UQ last Friday summarising her work. By analysing DNA extracted from tiger shark jaws and modern samples, Safia has been able to quantify a change in genetic diversity on the eastern compared to the western coast of Australia. Safia's project complements work underway by MFL group members Bonnie Holmes and Einar Nielsen on the genetics of this species in the Indopacific region.
This week postgrads from MFL and the Bennett lab at UQ are presenting their work at the Oceania Chondrichthyian Society conference in New Zealand.
