Stanovení bioindikačních hodnot rákosníčků (Coleoptera: Chrysomelidae: Donaciinae) evidovaných v České republice, včetně jejich aktuálního rozšíření a bionomických charakteristik

Abstrakt: The aim of this work is to assess the bioindicator value of the Donaciinae species recorded in the Czech Republic, based on three criteria: host-plant range; characteristics of habitat and the assessment of plants; assessment of Donaciinae species. Specific criteria allow both historical and recent records to be considered. A considerable amount of unpublished data from numerous different collectors is used, but particularly from the two authors. According to the results of the assessment of their bioindicator values, the species are divided into three groups (1st, 2nd and 3rd level indicators) and reference to their significance is one of a number of verified criteria for assessing the quality of wetland habitats. This work provides examples of application of the proposed evaluation to actual localities, and refers to 5 836 mostly unpublished records based on 18 903 specimen records and 48 025 observation records. Using these data, distribution maps were compiled, and the bionomy of each species discussed. The data on reed beetles covers the period from 1863 to the end of 2014.
