[Temperature as a factor of niche separation in free-living mesostigmatid mites (Mesostigmata: Arachnida, Parasitiformes) of storm detritus].
We carried out a laboratory investigation of temperature effect on survival as well as reproductive and trophic activities of mesostigmatid mites. Representatives of gamasid (three species) and uropodid (two species) mites abundant in storm detritus were used as model species. The upper reproduction limit and the upper survival limit were determined for the mites and their preys in the thermal range of 29-47 degrees C. Most of studied species managed to survive and propagate in a wide thermal range corresponding to the thermal gradient in the peripheral zones of the algal belts. The role of temperature as a factor of ecological niche separation in saprophytic Mesostigmata and formation of polydominant mite communities in the algal belts were demonstrated.
