Decline in tiger shark population defies expectations

Press Release Griffith UniversityAuthor: Deborah Marshall 10. September 2019 —– —— —– —– —- — New Griffith University research has revealed a 71% decline in tiger sharks across Queensland’s coastline. “This has been particularly rapid in southern regions which is unusual,’’ says lead author Dr Chris Brown from the Australian Rivers Institute. “Tiger sharks are

Life-history traits inform population trends when assessing the conservation status of a declining tiger shark population

Life-history traits inform population trends when assessing the conservation status of a declining tiger shark population Christopher Brown, George Roff ABSTRACT: The assessment of the conservation status of wide ranging species depends on estimates of the magnitude of their population trends. The accuracy of trend estimates will depend on where and how many locations within

Shark-based tourism presents opportunities for facultative dietary shift in coral reef fish

Shark-based tourism presents opportunities for facultative dietary shift in coral reef fish Joshua A. Drew, Mallory McKeon ABSTRACT: Tourism represents an important opportunity to provide sustainable funding for many ecosystems, including marine systems. Tourism that is reliant on aggregating predator species in a specific area using food provisioning raises questions about the long-term ecological impacts
