Important migratory corridor for endangered marine species off north-west Australia


The value of Australia's newly established network of marine parks has been highlighted by an international project that used satellites to track the vulnerable flatback sea turtle.

Researchers from Deakin University, Swansea University (United Kingdom) and Pendoley Environmental consultancy used advanced satellite tracking systems to record the passage of more than 70 flatbacks off the north-west Australian coastline.

A high value migratory corridor, more than 1,000 kilometres in length, was pinpointed, with about half the corridor contained within the network of marine reserves.

"Our findings show that much of the flatback turtle's transit passage – between its breeding colonies and foraging grounds – falls within the newly established Commonwealth Marine Reserve network," Deakin University animal movement expert Professor Graeme Hays says.

"These findings will help refine ongoing conservation planning to protect this wide-ranging turtle species using the Australian coast, including the identification of high use areas outside the existing reserve network."

"The migration corridor is located tens of kilometres from the Australian mainland and spans tens of kilometres in width."

"The flatback and other marine species in the area may be susceptible to accidental mortality, such as through collision with vessels and as fishery bycatch," he says.

Tracking devices were attached to the turtle's soft shell using a flexible harness that detached after about 12 months use. A signal, depicting the turtle's position was transmitted in real-time to a constellation of satellites known as the 'Argos system' as turtles surfaced to breathe – about once every 10 to 15 minutes.

The research, published this week in Marine Biology also highlights how whales, sharks and turtles share a common migration corridor, which was previously unknown.

Professor Hays says the team's findings can help inform conservation planning to ensure the flatback turtle is protected throughout its range – which may span many hundreds or even thousands of kilometres.

"The network of Australian marine reserves may also serve as a template for marine conservation elsewhere in the world," Professor Hays says.

"In recognition of the plight of the vulnerable flatback turtle, long-term conservation research programs are being developed to help protect this iconic species," he says.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
