DNA ‘fin(ger)printing’ reveals the secrets of white shark sex

Watch the video........Scientists have developed a unique statistical method to measure Australia’s two white shark populations (east and west), vital information to support management and conservation decisions relating to this iconic species. The method is part of a new toolkit of tagging, aerial survey and DNA fingerprinting being used to unlock the mysteries of shark life and death. We’re very close to unlocking the numbers in the east of Australia and now we have begun our work in south...

Sawfish rescue caught on video

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...

"To save fish and birds" The New York Times

5 February 2014

A global study by Tasmanian researchers shows what is needed to make marine parks effective, the findings of which were published in Nature.

In collaboration with overseas investigators and skilled recreational divers, University of Tasmania biologists, including researchers from the NERP Marine Biodiversity Hub, counted numbers and sizes of more than 2000 fish species along underwater transect lines set at 1986 sites in 40 countries. They then used this...

New hotspots of marine fish diversity revealed in Nature

26 September 2013

New global patterns of marine fish diversity have been revealed using information collected through a ‘citizen science’ initiative developed in Tasmania. As part of the Reef Life Survey program, committed recreational SCUBA divers are trained and supported to survey numbers of reef animals worldwide. Analysis of information provided by Reef Life Survey volunteers over the past six years has revealed new hotspots of marine biodiversity, including southwestern...

Hubs participating in Darwin’s National Threatened Species Day

Two NERP hubs are participating in this year’s National Threatened Species Day on Saturday 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. 

Northern Australia Hub scientists will demonstrate how mammal trapping equipment is used to survey small mammals, and there...

Underwater video from Abrolhos Islands

Recorded as part of a scientific research project conducted by the Department of Fisheries in collaboration with the University of Western Australia and CSIRO, this project aimed to describe and compare fish assemblages of the upper slope (100-600 m) along the west and north coasts of Western Australia. The footage was collected from a research survey in November 2010, onboard the Research Vessel Naturaliste. A total of 50 stereo-Baited Remote Underwater Videos were deployed, recording...
