12 February: Global connectivity of whale sharks?

“By collating available data on sightings, tracked movements and distribution information, this review provides evidence for the hypothesis of broad-scale connectivity among populations, and generates a model describing how the world’s R. typus are part of a single, global meta-population.”

Rhincodon typus migration patterns depicting probable sub-populations, possible links between sub-populations (aggregations), movements revealed from tagging data, and no current evidence for a migratory pathway (dashed arrows), except the questionable 13 000 km track across the Pacific Ocean from Eckert & Stewart (2001). See Sequeira et al. 2013 for more information.
