摘要：

Microparasites are common in Daphnia magna populations. We studied to what extent the infection with microparasites alters the habitat selection of the water-flea D. magna. In particular, we investigated whether the microsporidian microparasites Glugoides intestinalis, Flabelliforma magnivora, Ordospora colligata and Microl and the bacterium Pasteuria ramosa influence depth selection of Daphnia magna. All of them changed the spatial position during the day as compared to uninfected water-fleas. 24-h video sequences of hosts infected with Microl, Glugoides intestinalis or Pasteuria ramosa showed that night positions were not affected by parasitism. The results suggest that microparasites contribute to variation in depth selection of D. magna.
