Question: Environmental disturbance can disrupt habitat choice as an ecological barrier to hybridization between host-specific parasites that mate on their host. Is environmentindependent mate choice a sufficient barrier to prevent hybridization when ecological isolation breaks down? Hypothesis: Males and females will not discriminate between conspecific and heterospecific mating partners in the absence of host cues. Study system: Rhagoletis mendax and R. zephyria (Diptera: Tephritidae… CONTINUE READING
