Host-plant choices determined by reproductive interference between closely related butterflies

Naota Ohsaki, Masaaki Ohata, Yoshibumi Sato & Mark D. Rausher
A number of empirical studies have concluded that reproductive interference, RI, contributes to parapatric species distributions or sexual exclusion. However, the possibility that divergent host-plant use in phytophagous insects is due to sexual exclusion has seldom been considered. Here we present evidence that RI is responsible for different host-plant use by two Pierid butterfly species, Pieris napi and P. melete . When a novel host species was introduced about 50 years ago, two Pierid butterfly...

Aim Biogeographic barriers restrict the movement of individuals, resulting in population divergence, genetic differentiation, endemism and speciation. Yet, some barriers demonstrate unequal effect across species depending on species dispersal, which manifests in varying genetic structure. We test the hypotheses that the genetic structure of four coastal mangrove species would reflect differences in dispersal potential across the Malay Peninsula, a major biogeographic barrier in the Indo-West Pacific region. Location Twelve sites from the east and west...
