Parasite-related pairing success in an intermediate host, Caecidotea intermedius (Isopoda): effects of male behavior and reproductive physiology.


The acanthocephalan parasite Acanthocephalus dirus develops from the egg to the cystacanth stage inside the freshwater isopod Caecidotea intermedius. We have shown previously that cystacanth-infected male C. intermedius are less likely to initiate mating attempts with females than uninfected males in competitive situations. Here, we used a field-based… (More)
