HOST-DEPENDENT GENETIC STRUCTURE OF PARASITE POPULATIONS: DIFFERENTIAL DISPERSAL OF SEABIRD TICK HOST RACES
Despite the fact that parasite dispersal is likely to be one of the most important processes influencing the dynamics and coevolution of host-parasite interactions, little information is available on the factors that affect it. In most cases, opportunities for parasite dispersal should be closely li...

Despite the fact that parasite dispersal is likely to be one of the most important processes influencing the dynamics and coevolution of host-parasite interactions, little information is available on the factors that affect it.
