Dr Romina Henriques: The Benguela Current – a natural laboratory to study evolution.

Lecture Room, DIFS

Abstract
Oceanographic features, such as currents, fronts and upwelling cells, have been recognized as possible factors driving population differentiation within marine species.The Benguela Current, in southwestern Africa, is considered to be a major biogeographical barrier to the dispersion of tropical species between the Atlantic and Indo-Pacific Oceans.
But which features of the current are more likely to be behind this isolation? And is it only effective for tropical species?

 Using an array of molecular tools and five different fish species, I investigated the influence of the major oceanographic features of the system on population connectivity and evolutionary history of inshore, warm-temperate fishes. The obtained results suggest that the Benguela Current is a natural laboratory to study the evolutionary mechanisms shaping the evolutionary history of not only tropical but also temperate fish species.
