Tiger tracks – tiger sharks on Australia’s eastern coast

Bonnie Holmes‘ latest paper shows that the north-south movement of tiger sharks is linked to seasonal changes in water temperature.

Working at the most southerly extent of the distribution of the species and using electronic tags, Bonnie’s results shows that individuals move into temperate waters in the austral summer but return to the tropical north when local water temperature drops below about 19 C. Movement patterns like this (including from Sydney to New Caledonia across the Coral Sea) is a reminder to resource managers that cooperation among jurisdictions is important for the conservation of the species.
