Long-distance dispersal (LDD) involves movements outside the standard geographic limits and outside the genetic neighbourhood area of individuals. Although considered ‘rare’, LDD is important to amphibians at the population, species and community levels. To understand how LDD shapes current biogeographic patterns in these tetrapods, Luis F. Marin da Fonte and co-authors, in Frontiers of Biogeography, reviewed the cases reported in the literature.
In 41 studies, we recovered at least 90 LDD events (3 active, 87 passive) involving at least 56 extant species and 38 genera. Most events (73) involved the colonization of islands, with rafting being suggested as the most conceivable means of overwater passive dispersal for these vertebrates.we show that LDD events have played a significant role in shaping current amphibian biogeographic patterns, especially the occurrence of disjunct distributions and the colonization of islands.Marin da Fonte, L.F., M.
