Most of the mammals and birds of Jackson Hole harbor trematode parasites. The usual intermediate host in the life cycle of these flukes is a snail. My work during the past few years has dealt with stress on vertebrate hosts and its effect on their parasites. During the summer of 1971 I turned my attention to the invertebrate hosts of termatodes in a preliminary effort to determine if stress on these snails would be reflected in a change in the numbers of their larval fluke parasites. The work was done in the southern end of Grand Teton National Park. Project Number 103.
