Abstract: | Prey characteristics affecting vulnerability of a number of rotifer species to the predator Acanthocyclops robustus were investigated. Body volume was the main feature affecting the probability of attack after encounter and, with the exception of Polyarthra major, capture after attack. The lorica provided protection against predation in some species and a skipping escape response reduced the likelihood of capture in Polyarthra major. |
