          Abstract

          Parasitoid wasps are an extremely speciose, ecologically and economically crucial group of insects. Despite this, they have received disproportionally little attention from scientists, in particular in certain areas of the world. One such area is the Caribbean, where studies are scarce despite the importance of parasitoid wasps, and the uniqueness and diversity of the Caribbean islands. To verify whether an adequate diversity of parasitoid wasps at family level can be found to warrant future studies, this study carries out preliminary sampling in three localities in Jamaica. A total of 1522 individual parasitoid wasps, belonging to at least 16 different families collected during 16 events provide preliminary evidence there is in fact a high diversity of parasitoid wasps in Jamaica, and that future studies there, as in the rest of the Caribbean are definitely worthwhile.

          Analysis of an evolutionary species-area relationship.

          Large islands typically have more species than comparable smaller islands. Ecological theories, the most influential being the equilibrium theory of island biogeography, explain the species-area relationship as the outcome of the effect of area on immigration and extinction rates. However, these theories do not apply to taxa on land masses, including continents and large islands, that generate most of their species in situ. In this case, species-area relationships should be driven by higher speciation rates in larger areas, a theory that has never been quantitatively tested. Here we show that Anolis lizards on Caribbean islands meet several expectations of the evolutionary theory. Within-island speciation exceeds immigration as a source of new species on all islands larger than 3,000 km2, whereas speciation is rare on smaller islands. Above this threshold island size, the rate of species proliferation increases with island area, a process that results principally from the positive effects of area on speciation rate. Also as expected, the slope of the species-area relationship jumps sharply above the threshold. Although Anolis lizards have been present on large Caribbean islands for over 30 million years, there are indications that the current number of species still falls below the speciation-extinction equilibrium.
