Adapting a country-specific Dragonfly Biotic Index: Framework for seven Central European countries and transboundary pattern analysis

Popis výsledku v původním jazyce

Freshwater diversity is experiencing a significant crisis due to anthropogenic pressures and climate change, withlosses exceeding those in terrestrial ecosystems. The Dragonfly Biotic Index (DBI) offers an effective tool forassessing the health and ecological integrity of freshwater habitats through the presence/absence data of odonatespecies, which respond diversely to environmental changes. Each species within the assemblage is given a valuefrom 0 to 9, which is based on the sum of three sub-indices, each ranging from 0 to 3: distribution, threat, andsensitivity. Originally developed for South Africa, the DBI has been adapted to few regions worldwide. In thisstudy, we adapted the DBI for individual seven Central European countries (Austria, Czechia, Germany, Poland,Slovakia, Slovenia, and Switzerland) using updated species distribution data, national red lists and sensitivitybased on the species affinity to specific habitats and population trends. Furthermore, we analyzed transboundarypatterns of species distribution and threat, and tested how the subindices vary based on taxonomic and ecologicalclassification (Zygoptera vs Anisoptera, lotic vs lentic species). Our results revealed significant variation in DBIacross countries, emphasizing the importance of country-specific adoptions. Anisoptera exhibited moderate totalDBI values, whereas Zygoptera presented either high or low values. Furthermore, lentic species displayed lowersensitivity than lotic species. The newly presented DBI values offer a practical tool for conservation, enablingstandardized freshwater health monitoring and guiding efforts across Central Europe. This study underlines thenecessity of regularly updating DBI to reflect local ecological conditions, ensuring targeted freshwater conservation strategies.
