Mesostigmatid mites in four classes of wood decay.

We studied the mesostigmatid mite community in four classes of wood decay in mixed (pine-oak) forest stands in the Wielkopolska region, Cental-West Poland. A total of 80 samples, including bark, phloem and rotten wood of coniferous and deciduous species logs, were taken in August 2006 and 2007. Decay classes were a qualitative, categorical index based on visual assessment of decomposition in coarse woody debris.
