This study provides a first description of the phylogeographic patterns
and evolutionary history of two species of the mudskipper genus
Periophthalmus. These amphibious gobies are distributed throughout the
whole Indo-Pacific region and Atlantic coast of Africa, in peritidal
habitats of soft-bottom coastal ecosystems. Three sequence datasets of two
widely distributed species, Periophthalmus argentilineatus and P. kalolo,
were obtained by amplifying and sequencing two mtDNA markers (D-loop and
16S rDNA) and the nDNA rag1 region. The three datasets were then used to
perform phylogeographic, demographic and population genetic analyses. Our
results indicate that tectonic events and past climatic oscillations
strongly contributed to shape present genetic differentiation,
phylogeographic and demographic patterns. We found support for the
monophyly of P. kalolo, and only shallow genetic differentiation between
East-African and Indo-Malayan populations of this species. However, our
collections of the morphospecies P. argentilineatus include three
molecularly distinct lineages, one of them more closely related to P.
kalolo. The presence of Miocenic timings for the most recent common
ancestors of some of these morphologically similar clades, suggests the
presence of strong stabilising selection in mudskippers’ habitats. At
population level, demographic analyses and palaeoecological records of
mangrove ecosystems suggest that Pleistocene bottlenecks and expansion
plus secondary contact events of the studied species were associated with
recurrent sea transgressions during interglacials, and sea regressions or
stable regimes during glacials, respectively.
