abstract
Little is known about the intensity of endoparasite infection of small mammals much less the species of Eimeria (Apicomplexa: Eimeriidae) in many wild rodents. Eimeria is a diverse genus and the majority of mammals surveyed to date harbor at least one species. Given that standard field methodologies often have fecal samples collected from potential hosts when live traps are checked early in the morning, the presence of some Eimeria may go undetected if the parasites are shed later in the day. To determine if there is a relationship between time of day and intensity of infection (measured by the number of Eimeria/pellet) we collected fecal samples from live-trapped southern red-backed voles (Clethrionomys gapperi) from Grand Teton National Park. Live specimens were taken from the field and held for 24 hours, during which pellets were obtained an average of every 8 hours. Pellets were stored in 2% potassium dichromate until sporulation could take place. Of the 51 voles sampled, 19 were infected with Eimeria. Measurements of the sporulated oocysts indicate the species E. Clethrionomyis present in the red backed vole. Though sample size is low, correlation analysis reveals no relationship between time of day and intensity of infection.
