| the distribution of echinococcus granulosus in moose: evidence for parasite-induced vulnerability to predation by wolves? | the role of parasites in influencing the trophic dynamics of hosts is becoming increasingly recognized in the ecological literature. echinococcus granulosus is a tapeworm that relies on the predator-prey relationship between the definitive host (wolf, canis lupus) and the intermediate host, (moose, alces alces) to complete its life cycle. heavy infection by e. granulosus may predispose moose to increased risk of predation by wolves. theory predicts that parasite-induced vulnerability to predatio ... | 2004 | 15232731 |
