Genetic differentiation in Philippine bats of the genera Cynopterus and Haplonycteris

Genetic differentiation in Philippine bats of the genera Cynopterus and Haplonycteris Genetic variation and differentiation in six island populations of two species (Cynopterus brachyotis Müller and Haplonycteris fischeri Lawrence) of Philippine fruit bats (Chiroptera, Pteropodidae) were analysed using allozyme electrophoresis. Cynopterus is eurytopic and widespread in southeast Asia; Haplonycteris is stenotopic and endemic to the Philippines. Genetic variability within populations is consistently higher in Cynopterus, but differentiation between populations is much more pronounced in Haplonycteris. Genetic variation is not significantly correlated with island size in either species, but a positive trend is present in both. Levels of gene flow are sufficiently low to allow differentiation by genetic drift alone in Haplonycteris (Nm= 0.05), but not in Cynopterus (Nm= 7.5). There is no significant association between genetic distance and distance between sampling sites; however, between‐population differentiation is positively related to degree of geographic isolation during Pleistocene periods of low sea level and to vagility and consequent levels of gene flow among populations. Significant effects of population size on genetic differentiation were not found. Genetic distance matrices for the two species share a common structure that is similar to patterns of mammalian faunal similarity for the Philippines as a whole, suggesting similar effects of geographic and/or environmental factors. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Biological Journal of the Linnean Society Wiley

Abstract

Genetic variation and differentiation in six island populations of two species (Cynopterus brachyotis Müller and Haplonycteris fischeri Lawrence) of Philippine fruit bats (Chiroptera, Pteropodidae) were analysed using allozyme electrophoresis. Cynopterus is eurytopic and widespread in southeast Asia; Haplonycteris is stenotopic and endemic to the Philippines. Genetic variability within populations is consistently higher in Cynopterus, but differentiation between populations is much more pronounced in Haplonycteris. Genetic variation is not significantly correlated with island size in either species, but a positive trend is present in both. Levels of gene flow are sufficiently low to allow differentiation by genetic drift alone in Haplonycteris (Nm= 0.05), but not in Cynopterus (Nm= 7.5). There is no significant association between genetic distance and distance between sampling sites; however, between‐population differentiation is positively related to degree of geographic isolation during Pleistocene periods of low sea level and to vagility and consequent levels of gene flow among populations. Significant effects of population size on genetic differentiation were not found. Genetic distance matrices for the two species share a common structure that is similar to patterns of mammalian faunal similarity for the Philippines as a whole, suggesting similar effects of geographic and/or environmental factors.
