Trapping liquids may bias the results of beetle diversity assessment.

Several different techniques and methods are used to capture and study beetles (Coleoptera). One option is the use of window traps with various trapping liquids. However, these liquids used in comparative studies may have a biasing effect on the results.

Small-scale spontaneous dynamics in temperate beech stands as an importance driver for beetle species richness.

Natural dynamics in forests play an important role in the lives of many species. In the landscape of managed forests, natural disturbances are reduced by management activities. This usually has a significant effect on insect diversity.
