Building Geographic Distribution Models for Five Plant Genera on Madagascar.

The processes driving species radiations of plants on Madagascar remain inadequately explored. The wide variety of climates on Madagascar and the remarkable contrast between the eastern and western sides of the island have been long been invoked to explain the extraordinary degree of microendemism. Recent patterns of speciation identified in the island’s rich fauna are complicated and suggest that many processes have contributed. Many speciation hypotheses have been put forth though relatively few have been explicitly tested in Malagasy plants. We reconstruct the geographic distribution of species in the Hibiscus tribe (Malvaceae) as a first step to uncover some of the driving forces in speciation on Madagascar. Using georeferenced distribution records from the herbaria of MO and P as well as personal field collections, the range of 27 species were determined and adjusted with environmental niche modeling using climate data for each of the 19 BIOCLIM variables downloaded from the WorldClim data set. The resulting maps were used to calculate species richness and endemism rates throughout the group.
