| Summary: | A multidisciplinary synthetic approach to investigation of factors underlying patterns of saproxylic diversity is urgently needed to gain scienti cally sound base for conservation and forestrymanagements of temperate woodlands. We propose to investigate e ects of numerous factors of various temporal and spatial scales on saproxylic organisms. We will thoroughly sample saproxylic insect assemblages accross large area of woodlands renowned as saproxylic diversity hotspot in Central Europe. Together with various parameters of the environment such as dead-wood volume, old-tree density, stand age and tree species composition, we will geodatabase data on historical and recent land use/land cover, historical and recent extent of key habitats in the area. Relating composition and diversity of insect assemblages to the environmental data will allow for identi cation of the key factors a ecting saproxylic organisms. Accumulated information will be used to model survival/extinction scenarios under di erent management regimes. |
