Trans-Atlantic Dispersal: Several Examples of Colonization of the Gulf of Biafra by Middle American Stocks of Carabidae

  • Philip Bruneau de Miré

Abstract

Although the fauna and flora of tropical America and Africa have been isolated for an extended period, many taxa of various ranks are shared between the two areas. Some of this vicariance is explained by the physical separation of ancestral stocks that took place when Gondwana was fragmented in the vicinity of the mid-Atlantic ridge, and the resulting continental blocks drifted apart. On the other hand, similarities exhibited by some apparent pairs of vicarious taxa are the result of convergent evolution. However, a few similarities exhibited by the two biotas cannot be explained simply in terms of either convergence or residual elements.
