We characterized the ecological niches of several planktonic prostome ciliates with respect to their food demand and temperature. We found intergeneric differences between Balanion planctonicum and the 2 Urotricha spp., U. furcata and U. farcta. There were also significant interspe- cific differences within the genus Urotricha and intraspecific differences between 2 Balanion spp. and 3 U. furcata isolates from distant lakes. Relative to Urotricha spp., Balanion appeared to be the superior competitor at low to medium food concentrations and reached high growth rates at moder- ate temperatures. The threshold prey concentration for positive population growth of B. plancton- icum was lower than that obtained for the 2 Urotricha spp., but higher than that reported earlier for the marine species, B. comatum. A third Urotricha species, U. castalia, was investigated for its tem- perature response only. The temperature response revealed species-specific temperature adaptation between B. planctonicum and the sympatric U. furcata, and further differences within the genus Urotricha: U. farcta grew fastest at high temperatures; U. castalia was adapted to low temperatures; and U. furcata peaked at moderately warm temperatures.
