- Description:
- High host specificity and dependence on the host plants are common attributes of herbivorous insects. Their usage in ecosystem studies and landscape assessment is shown by examples from a group of Central European weevils and leaf beetles. Biodiversity can be assessed from the degree of completeness of present herbivore feeding guilds. Wingless species with narrow habitat requirements can be used as good bioindicators of relic natural habitats. and Pavel Špryňar, Jaromír Strejček.

- Description:
- This area in Central Bohemia is characterized by predominantly limestone bedrock and fully-developed karstic phenomena – the main reasons for its high botanical di - versity and occurrence of many rare and endangered species. In the center of the area, well-developed broad-leaved forests are found, as well as xerothermophilous non-forest vegetation. At the borders of the area, acidophilous, basiphilous and serpen - tinophilous plants occur on non-calcareous rocks (e. g. slates, basaltoids, picrites). and Pavel Špryňar.
