Rezultati istraživanja reke Save (2006) - akvatični makrobeskičmenjaci

Abstract

The paper presents some results of the 2006 Sava survey. The investigation was carried out at four locations along 188 km of the Serbian stretch of the Sava River (206 km of the river belongs to Serbia). Among other things (physical and chemical properties of water and sediment, phytoplankton, and phytobenthos), the study included investigation of aquatic macroinvertebrates. Sixty-two taxa were identified in this typical lowland river. Mollusks and oligochaetes were the most diverse groups of macroinvertebrates. Our results support the hypothesis that the Sava River is an important bio-invasion trajectory, a part of the Southern Invasive Corridor of Europe. Five alien macroinvertebrate taxa were identified, some of which (Corbicula fluminea, Branchyura sowerbyi, and Anodonta woodiana) were found to be important components of the community.

Cilj rada je da se prikaže deo rezultata istraživanja na reci Savi tokom 2006. Istraživanje je vršeno na četiri lokaliteta duž 188 km rečnog toka Save kroz Srbiju (od 206 km ukupne dužine toka). Pored istraživanja ostalih parametara (analiza fizičkih i hemijskih karakteristika vode, sedimenta, fitoplanktona i fitobentosa) vršena su i istraživanja akvatičnih makroinvertebrata. Ukupno je zabeleženo 62 taksona. Najraznovrsnije grupe su Oligochaeta i Mollusca. Dobijeni rezultati potvrđuju pretpostavku da je reka Sava važan invazivni put i da predstavlja deo južnoevropskog invazivnog koridora. Ukupno je zabeleženo 5 alohtonih vrsta makroinvertebrata, od kojih neke pred stavljaju važne komponente zajednice (Corbicula fluminea, Branchyura sowerbyi, i Anodonta woodiana).
