| distribution, abundance, and genetic diversity of clinostomum spp. metacercariae (trematoda: digenea) in a modified ozark stream system. | abstract land-use alterations can have profound influences on faunal distributions, including host-parasite relationships. yellow grub trematodes ( clinostomum spp.) have complex life cycles involving 3 hosts: a snail, a fish or amphibian, and a bird. here, we analyze the distribution, prevalence, intensity, abundance, and genetic diversity of encysting metacercariae of clinostomum spp. in salamanders and fishes throughout an aquatic system that includes a natural ozark stream and man-made ponds ... | 2011 | 21506775 |
