森林结构是持续进行的全球气候和土地利用变化的重要稳定因素。具有自然结构的生物多样性山区森林是受这些问题危害最大的生态系统之一。我们重点研究了欧洲山毛榉（Fagus sylvatica）的山林岛及其在生物自然分布中的作用。研究区域位于捷克最古老的国家公园，克尔科诺谢（Krkonoše）（385平方公里），是该国最高的山脊。我们研究了多类群（地衣，甲虫和膜翅目）对环境的三个分层空间水平的响应：地形由海拔梯度描述；地形由海拔梯度描述。斑块的结构通过冠层的开放度，枯木量和挪威云杉（Picea abies）的覆盖来描述；并通过采样树的种类及其直径描述树的级别。地衣倾向于较高的海拔，而昆虫群则相反。此外，昆虫群主要受山毛榉岛内部斑块结构的影响。地衣可能会因预计未来温度升高而受到危害，因为它们将需要转向更高的高度。未来，土地用途的变化（即森林经营）可能会威胁到昆虫的威胁-冠层开放度和枯木量的相互联系表明了这一点。因为他们需要转向更高的高度。未来，土地用途的变化（即森林经营）可能会威胁到昆虫的威胁-冠层开放度和枯木量的相互联系表明了这一点。因为他们将需要转向更高的高度。未来，土地用途的变化（即森林经营）可能会威胁到昆虫的威胁-冠层开放度和枯木量的相互联系表明了这一点。

Biodiversity in remnants of natural mountain forests under conservation-oriented management.

The structure of forests is an important stabilizing factor regarding ongoing global climate and land use change. Biodiverse mountain forests with natural structure are one of the ecosystems most endangered by these problems. We focused on the mountain forest islands of European beech (Fagus sylvatica) and their role in the natural distribution of organisms. The study area was situated in the oldest Czech national park, Krkonoše (385 km2), which is the highest mountain ridge in the country. We studied multi-taxa (lichens, beetles and hymenopterans) responses to three hierarchical spatial levels of the environment: the topography was described by the elevation gradient; the patch structure was described by canopy openness, dead wood amounts, and Norway spruce (Picea abies) cover; and the tree level was described by species of the sampled tree and its diameter. Lichens preferred higher elevations, while insect groups responded conversely. Furthermore, insect groups were mainly influenced by the inner patch structure of beech islands. Lichens may be jeopardized due to the predicted future increase in temperatures, since they would need to shift toward higher altitudes. Insects may be mainly threatened in the future by land use changes (i.e., forest management) - as indicated by an interconnection of canopy openness and the amount of dead wood.
