Abstract
Istraživanje rasprostranjenosti viših rakova iz redova Amphipoda (rakušci) i Isopoda (jednakonožni rakovi) provedeno je duž toka rijeke Gacke i u njenim pritocima. Uzorci su prikupljeni u lipnju 2020. g. pomoću ručne bentos mreže na ukupno 14 postaja (Gacka-9, pritoci-5 postaja). U glavnim izvorima, Tonković i Majerovo vrilo, i u gornjim dijelovima toka Gacke dominirale su vrste Synurella ambulans i Asellus aquaticus. Rakušac Gammarus balcanicus je veće gustoće imao na srednjim i donjim dijelovima toka, te u pritocima, a uopće nije pronađen na izvoru Majerovo vrilo i još jednoj postaji nizvodno od ovog izvora. Ovakav obrazac rasprostranjenosti i gustoće tri istraživane vrste zabilježen je samo u rijeci Gackoj. U svim drugim krškim rijekama u Hrvatskoj je G. balcanicus dominantna vrsta s najvećim gustoćama u izvorima i gornjim dijelovima toka rijeka. Pretpostavlja se da je to posljedica nekadašnjeg presušivanja i potencijalnog onečišćenja izvora i gornjih dijelova toka rijeke Gacke.
Abstract (english)
The study of the distribution of macro-crustaceans from the orders Amphipoda and Isopoda was conducted along the course of the Gacka River and its tributaries. Samples were collected in June 2020 using a benthic net at a total of 14 sites (Gacka-9, tributaries-5 sites). In the main springs, Tonković and Majerovo vrilo, and in the upper parts of the Gacka River, the amphipod Synurella ambulans and isopod Asellus aquaticus were dominant species. The amphipod Gammarus balcanicus had higher densities in the middle and lower parts of the river, as well as in the tributaries, and was not found at the source of Majerovo vrilo and another station downstream from this source. This distribution pattern and density of the three investigated species were unique to the Gacka River. In all other karst rivers in Croatia, G. balcanicus is the dominant species with the highest densities in the springs and upper parts of the river. It is assumed that this is a result of past drying up and potential pollution of the source and upper parts of the Gacka River.
