Species-specific pattern of crayfish distribution within a river network relates to habitat degradation: implications for conservation

Popis výsledku v původním jazyce

The degradation of aquatic habitats has increasingly become one of the most important factors influencing the distribution of freshwater species worldwide. We ana- lysed the occurrence of three crayfish species, Astacus astacus, Austropotamobius tor- rentium and Orconectes limosus, in relation to habitat degradation status (based on Directive 2000/60/ES), stream morphology, geographical characteristics and land cover. In total, we analysed 6,768 sites within the Czech Republic (Central Europe), of which6,187 sites lacked crayfish; among the remainder, A. astacus was present in 507 sites, O. limosus occurred in 44 sites and A. torrentium was present in only 30 sites. The analysis revealed that A. astacus preferred streams of better water quality that were not surrounded by agricultural land or settlements. This species also preferentially occurred in smaller streams with stony bottom substrata that were located at higher altitudes. Austropotamobius tor- re
