Distribution and Seasonal Dinamics of Ephemeroptera and Plecoptera in the River Oskova

Abstract

Invertebrates are the basisof biodiversity of Bosnia and Hercegovina's fauna, but just invertebrates are the least researched. During the research of EPHEMEROPTERA and PLECOPTERA in the river Oskova there were sampled 23 species of EPHEMEROPTERA with a total of 398 individuals and 17 species of PLECOPTERA with 352 individuals. Based on the research conducted in the river Oskova we obtained data about the composition of macroinvertebrate communities, determined taxa and distributions and obtained data on water quality. The results indicate favorable conditions for life of macroinvertebrates, relatively high diversity, and can be used for finding effective control and biomonitoring of the analyzed ecosystem.

Beskičmenjaci čine okosnicu biodiverziteta bosansko-hercegovačke faune, ali su upravo beskičmenjaci i najslabije istraženi organizmi. Prilikom istraživanja EPHEMEROPTERA i PLECOPTERA u rijeci Oskova uzorkovane su 23 vrste EPHEMEROPTERA sa ukupno 398 jedinki i 17 vrsta PLECOPTERA sa 352 jedinke. Na osnovu sprovedenih istraživanja dobijeni su podaci o sastavu zajednica makroinvertebrata, izvršena je determinacija taksona i njihova distribucija, što je omogućilo davanje ocjene o kvalitetu vode. Rezultati istraživanja ukazuju na povoljne uvjete za život makroinvertebrata i njihov relativno visok diverzitet, tako da se ovi organizmi mogu upotrijebiti za pronalazak efikasne kontrole i biomonitoringa rijeke Oskove.
