CLIOTOP

The CLimate Impacts on Oceanic TOp Predators (CLIOTOP)  is an IMBER regional programme. It was established in 2005 and is now in its third phase (2016-2020).

CLIOTOP is an international research network open to researchers, managers, and policy makers involved in marine research related to large marine species. Network participants organise large-scale comparative efforts to elucidate key processes involved in the interaction between climate variability and change and human uses of the ocean on the structure of pelagic ecosystems and large marine species. CLIOTOP seeks to develop predictive capability for these socio-ecological systems and evaluate adaptation options to ensure future sustainability. The successful implementation of CLIOTOP will provide information, products and tools for better resource and conservation management.

Global patterns and trends of tuna isotopes

Stable carbon and nitrogen isotope analysis is a common tool to estimate trophic position and examine habitat patterns of a range of coastal and marine predators, but due to the extensive oceanic habitat and logistics required to conduct wide-scale sampling, global comparisons have been limited to date. The CLIOTOP 2016-01 ‘Tuna Isotopes’ Task Team recently convened two workshops in Hobart, Australia to draft two scientific papers.
