Timber stacks: potential ecological traps for an endangered saproxylic beetle, the Rosalia longicorn Rosalia alpina

摘要: Ecological traps are serious, anthropogenic threats to animal populations. However, in certain cases it is difficult determine whether they really act the expected manner. This applies harmful effects of beech timber stacked forests on endangered saproxylic beetle Rosalia longicorn alpina, which have been mentioned numerous scientific articles, conservation action plans and similar publications. The aim this paper stacks meet criteria an ecological trap for longicorn. Two basic such a analysed: attractiveness impossibility complete larval development. results show that highly attractive imagines. Moreover, time during shown be significantly shorter than species’ development period. These suggest can treated as operative longicorn, even though extent their influence demographic parameters beetle’s population has not estimated. Forest management practices, i.e. increasing amounts shifts timing wood storage, could intensify threat.
