• W570240757 abstract "The islands of the West Indies are considered to be a biodiversity hotspot with a high amount of endemic species for the whole region and on certain islands. In terms of freshwater crabs, the island of Jamaica harbors the greatest amount of endemic species in the Caribbean. These freshwater crabs belonging to the family Sesarmidae are the result of an adaptive radiation (Schubart et al., 1998a), which occurred after the colonization of the island by a marine ancestor approximately 4.5 mya. Currently, ten different freshwater species of Sesarma are known from Jamaica. On the other islands of the Greater Antilles no entirely freshwater sesarmid crab can be found. Instead, freshwater crabs belonging to the family Pseudothelpusidae are present, but in much lower species richness. The island of Puerto Rico for example is only inhabited by a single endemic freshwater crab species, Epilobocera sinuatifrons A. Milne Edwards, 1866. The aim of this study was to determine the processes and mechanisms which lead to the differences in freshwater crab diversity between the otherwise similar islands of Jamaica and Puerto Rico. A further aim was to investigate, if the species number on Puerto Rico was underestimated due to possible existence of cryptic species or the species number on Jamaica overestimated and the recently described species not completely isolated. The population structure of Epilobocera sinuatifrons, Sesarma dolphinum Reimer, Schubart & Diesel, 1998, Sesarma windsor Turkay & Diesel, 1994 and Sesarma meridies Schubart & Koller, 2005 was analysed using morphometric methods, a mitochondrial and a nuclear genetic marker.In the case of Epilobocera sinuatifrons, no evidence for the presence of cryptic species could be found. Furthermore, the overall differentiation between the populations is low and gene flow is ongoing and unrestricted. Only a gradient between the eastern and western part of the island is present. The analysis of the population structure of the Jamaican sesarmids support the species status of the recently described species and no evidence for hybridization could be found with he nuclear markers. It also revealed a high diversity between the different populations of the three investigated species. The gene flow between the different populations of the species turn out to be stronger restricted with greater geographic distances between the populations. Belonging to the same larger drainage system does not necessarily allow gene flow between populations or cause mixing or hybridization between species, suggestion isolation in the upper reaches of the rivers.As a conclusion, the different abilities for dispersal seem to have a great impact on the observed differences of species diversity between the two freshwater crab lineages. The high ability of terrestrial movement leads to ongoing gene flow within the species of Epilobocera sinuatifrons. The apparent retention of larvae and juveniles in the parental habitat is probably the key innovation which lead diversification and adaptive radiation in the Jamaican sesarmid crabs." @default.
