| the contributions of host age and size to the aggregated distribution of parasites in yellow perch, perca flavescens, from garner lake, alberta, canada. | the independent effects of host age and size on parasite abundance are examined in yellow perch from garner lake in east-central alberta. older, larger perch tend to have more species of parasites combined with larger parasite infrapopulations. sexual size dimorphism in perch generates 2 different size classes within each age class >2+ yr, thus allowing the opportunity to separate the effects of age and size on the recruitment of parasites by perch. the abundances of diplostomum adamsi and bothr ... | 1998 | 9488333 |
| circulation of parasites among fishes from lakes in the caribou mountains, alberta, canada. | circulation of 24 macroparasite species among 12 species of fish was evaluated within samples of hosts collected from 9 lakes on an isolated plateau in northern alberta, canada. twenty-seven parasite taxa (24 species plus the larval stages of triaenophorus crassus, t. stizostedionis, and raphidascaris acus) had the potential to be circulated among hosts. sixteen parasite taxa were recovered from a single host species within a lake. of the 11 remaining nonspecialist taxa, 4 were larval stages tha ... | 2003 | 12760632 |
