Floriaan is currently completing his PhD (From rivers to ocean basins – quantifying sex-specific connectivity in sharks) as part of NESP Marine Biodiversity Hub Project A1 - Northern Australian hotspots for the recovery of threatened euryhaline species.
The project aims to investigate reproductive connectivity in well-defined river shark (Glyphis glyphis and Glyphis garricki) populations. By applying novel molecular techniques, we will improve our understanding on male-specific gene flow and female philopatry.
Floriaan is a marine biologist with significant experience in genetics and genomics, including eDNA, metabarcoding and population genetics, as well as ecology (invasive species and remote fieldwork) and bioinformatics.
Master in Marine Biodiversity and Conservation (EMBC+) at the University of Ghent and the University of Oviedo
Bachelor in Biology at the University of Leuven
Sawfish Day is an annual event to raise awareness of these vulnerable animals and to highlight the threats they face in order to safeguard their future. Now in its second year, help raise awareness of this special day and of these magnificent marine animals,by sharing these links with your social networks:
In early 2017, a 2.7-metre Largetooth Sawfish was caught by local woman Lisa Smiler at Wattie Creek, a tributary of the Victoria River near...
In September 2017, a Marine Biodiversity Hub team worked to rescue a large group of Largetooth Sawfish trapped in a drying floodplain waterhole and relocate the animals to the main channel of the river. The small waterhole where the rangers located the sawfish was completely dry soon after the rescue.
Australia’s northern rivers are a last remaining stronghold for the threatened Largetooth Sawfish (Pristis pristis), but even in this relatively pristine part of the world sawfish...
Two threatened marine species urgently need sustainability assessments before future wild harvests are conducted for public aquarium displays, a Charles Darwin University researcher warns.
PhD candidate Kate Buckley has devised a new three-step approach to inform relevant authorities of the need for sustainability assessments before permitting the removal of threatened, or data-deficient and potentially threatened, shark and ray species (elasmobranchs) from the wild.

The trip brought together researchers from Charles Darwin University Research Institute for the Environment and Livelihoods, the North Australian Indigenous Land and Sea Management Alliance Ltd (NAILSMA), and Malak...
A new species of giant stingray has been named after being encountered by scientists in northern Australian rivers, coastal Papua New Guinea and the Arafura Sea.
Urogymnus acanthobothrium, is described today in the journal Zootaxa by scientists from CSIRO’s Australian National Fish Collection (ANFC) and Charles Darwin University (CDU).
‘This is one of the world’s largest stingrays, growing to a width of at least 1.6 metres, and it occurs in both rivers and marine waters,’ Dr...
Indigenous panellists from Australia and New Zealand will meet in Wellington, New Zealand, on Monday 4 July to consider ways for the marine science and Indigenous communities to engage more effectively in research partnerships.
The panel discussion will take place during the 2016 conference of the New Zealand Marine Sciences Society (NZMSS) and the Australian Marine Sciences Association (AMSA), to be held from 4─7 July at Victoria University, Wellington.

Sawfishes and river sharks are protected species; if they are caught by recreational anglers they must be released safely back into the water. Fishers who are lucky enough to experience a close encounter with one of our protected sawfish or river shark species are meeting with some of the most interesting inhabitants of our northern waterways. By reporting sightings anglers can help researchers better understand the distribution of these...
Australia’s Environment Minister, the Hon Greg Hunt MP, joined University of Tasmania scientists and volunteer divers on a Reef Life Survey at Tinderbox Marine Reserve south of Hobart today.
After the dive, the Minister joined UTAS Vice Chancellor, Professor Peter Rathjen, at Hobart’s Institute for Marine and Antarctic Studies to launch the Marine Biodiversity Hub, one of six hubs funded under the National Environmental Science Programme (NESP).
The NESP is a six-...

Travel down Kakadu's West Alligator River with Hub scientist Peter Kyne as he surveys the endangered Northern River Shark and critically endangered Speartooth shark.
These river shark surveys have been undertaken during research for the Marine Biodiversity Hub project "Supporting management of listed and rare species", a collaboration between Charles Darwin University, Northern Territory Fisheries and CSIRO.

The Australian Government has announced the successful organisations to lead research hubs under the $142.5 million National Environmental Science Programme (NESP). The programme will assist decision-makers to understand, manage and conserve Australia's environment by funding world-class biodiversity and climate science. This research will ensure decisions about managing Australia's biodiversity and environmental resources are made on the best available...
Two NERP hubs are participating in this year’s National Threatened Species Day on Sunday 7 September at Darwin Waterfront – the Northern Australia Hub and Marine Biodiversity Hub. Videos, slide shows and brochures will focus on the management of listed and rare species including sawfish and river sharks, and the impact feral cats are having on native mammals. The event is being marketed as a Pop-up-Zoo with experts from a wide range of organisations providing an overview of their work....
Sharks and rays are some of the world’s most threatened animals, with a quarter of all species at risk of extinction. Among the sharks and rays, sawfish are some of the most threatened, with all five species listed as Critically Endangered or Endangered by the International Union for Conservation of Nature (IUCN). Read the full story in The Conversation, 18 April 2014.

In September 2012, as Top End floodplains were drying, NERP Marine Biodiversity Hub and Northern Hub scientist Peter Kyne received an alert from Daly River Traditional Owner Rita Purak that two largetooth sawfish (Pristis pristis) were stranded in a waterhole near the Daly River. Rita knew the sawfish were uncommon because she had been helping Charles Darwin University scientist Peter Kyne and CSIRO's Richard Pillans with their field work, monitoring the movements of sawfish in the Northern...
In September 2012, as Top End floodplains were drying, NERP Marine Biodiversity Hub and Northern Hub scientist Peter Kyne received an alert that two largetooth sawfish (Pristis pristis) were stranded in a waterhole near the Daly River.
The call was from the Malak Malak Indigenous Ranger Group who knew the sawfish were uncommon because they had been helping Peter and his colleague Richard Pillans with field research.
‘After a two-hour drive across a rugged dry floodplain, we...
