New Paper: Identification through DNA Barcoding – a powerful oppurtunity for ecologists

Professor Corey Bradshaw

A new paper titlted ‘Identification of Rays through DNA Barcoding: An Application for Ecologists‘ investiges DNA barcoding and its use as a potentially powerful ecological tool to support and confirm species identifications and to highlight species complexities. DNA Barcoding is used to investigate tropical rays as part of the ecological study.

The paper involves Environment Institute member Corey Bradshaw as well as Florencia Cerutti-Pereyra (Charles Darwin University), Mark Meekan (Australian Institute of Marine Science), Nu-Wei Wei (Charles Darwin University), Owen O’Shea (Murdoch University), Chris Austin (School of Science Monash University Sunway Campus) and has been published in PLoS ONE.

New Paper: Accuracy of species identification by fisheries observers in a north Australian shark fishery

A new paper involving Environment Institute member Corey Bradshaw, as well as Bree Tillett (Charles Darwin University & Australian Institute of Marine Science), Iain Field (Charles Darwin University, Australian Institute of Marine Science and Macquarie University), Grant Johnson (Northern Territory Fisheries), Rik Buckworth (Northern Territory Fisheries & CSIRO), Mark Meekan (Australian Institute of Marine Science) and Jennifer Ovenden (Queensland Government) has recently been published in the journal Fisheries Research.

The paper titled, ‘Accuracy of species identification by fisheries observers in a north Australian shark fishery’ provides the first estimates of the ability of scientific observers to identify five species of morphologically-similar carcharhinid sharks in a fishery in northern Australia.  Results provide the first benchmark of identification accuracy of observers for carcharhinid sharks in northern Australia and show that estimates of error in species identifications need to be incorporated into management strategies to ensure successful recovery of the many recently over-fished shark populations.
