In the study, scientists examined 56 years of fisheries data documenting the return of sockeye salmon to the Fraser River in British Columbia – and the route they chose around Vancouver Island showed a correlation with changes in the intensity of the geomagnetic field.

Salmon originating from Oregon that has spent two to four years in the northern Pacific Ocean off Canada or Alaska would return as adults, the scientists speculate, journeying southward off the coast until they reached a magnetic field intensity similar to that of their youth.

In response to the call for champions in support of the Aichi Biodiversity Targets, the Republic of Maldives has pledged to become the first nation where the entire country and its Exclusive Economic Zone will be a Biosphere Reserve.

The Biosphere Reserve’s strategy must integrate management of natural resources with conservation and sustainable use. The plan also must seek to ensure equitable distribution of natural resource wealth. Currently, there are 610 biosphere reserves in 117 countries.
