Abstract
Vodene muhe plesačice (Empididae; Clinocerinae, Hemerodromiinae) su kukci koji čine važnu ekološku komponentu slatkovodnih ekosustava, posebice tekućica. Ličinke i kukuljice žive u vodenim staništima, a odrasli na kopnu. Ciljevi ovog istraživanja su bili analizirati preferenciju pojedinih vrsta prema određenom tipu mikrostaništa. Jedan od ciljeva bio je i utvrditi glavne ekološke čimbenike koji utječu na sastav, brojnost jedinki i emergenciju te gustoću populacija najzastupljenijih vrsta na 2 različita krška slatkovodna staništa te povezati njihovu brojnost i emergenciju s raspoloživim plijenom. Uzorkovanje je provedeno mjesečno od 2007. do 2010. godine na 2 postaje unutar NP Plitvička jezera: Izvor Bijele rijeke i Barijera Labudovac. Odrasle jedinke uzorkovane su piramidalnim emergencijskim klopkama. Na svakoj postaji postavljeno je 6 klopki na različita raspoloživa mikrostaništa. Tijekom istraživanog razdoblja zabilježeno je ukupno 1896 jedinki i 13 vrsta vodenih muha plesačica; 8 iz potporodice Hemerodromiinae i 5 iz potporodice Clinocerinae. Na postaji Izvor Bijele Rijeke utvrđen je najveći broj vrsta (9) i najveća raznolikost vodenih muha plesačica. Temperatura vode i fotoperiod su izdvojeni kao najvažniji ekološki čimbenici koji uvjetuju emergenciju, dok protok vode značajno utječe na sastav zajednice vodenih muha plesačica. Vodene muhe plesačice najbrojnije su na mikrostaništima s mahovinom. Najveća emergencija zabilježena je iznad onih mikrostaništa gdje je prisutan najveći broj jedinki potencijalnog plijena i gdje je najveća brzina strujanja vode. Tijekom istraživanog razdoblja zamijećene su značajne promjene gustoće populacije vrste Chelifera siveci, a najvjerojatnije su uzrokovane razlikama u odnosu spolova tijekom godina. Kod vrste Hemerodromia unilineata nema značajnih promjena u gustoći populacije tijekom istraživanog razdoblja.
Abstract (english)
Aquatic dance flies (Empididae; Clinocerinae, Hemerodromiinae) are insects which make an important ecological component of freshwater ecosystems, especially in running waters. Larvae and pupae live in water habitats, while adults live on land habitats close to water. The goals of this study were to analyse their preference for various microhabitats, main ecological factors that have influence on composition and abundance of specimens and emergence of species at two different freshwater karst habitats. Also correlations between abundance of aquatic dance flies and amount of their prey were explored as well as changes in population density for most common species. Sampling was made monthly from 2007 until 2010 at Plitvice lakes, on Spring of Bijela rijeka and Tufa Barrier Labudovac. Adult specimens were collected using a semi quantitative method of emergence with 6 traps placed on each location. A total of 1823 adult Empididae individuals of which 13 species were caught during four years study, 8 species from subfamily Hemerodromiinae and 5 from subfamily Clinocerinae. The greater number of species (9 species) and highest indexes of diversity was recorded at the spring of Bijela rijeka. Water temperature and photoperiod are the main ecological factors influencing their emergence, while water discharge is the main factor influencing the assemblage composition of aquatic dance flies. The highest abundance of aquatic dance flies on spring site was recorded on moss. The highest emergence rates were recorded above microhabitats with highest prey densities and with highest current velocity. Density changes over four- year period was recorded for population of Chelifera siveci. It may be caused by differences in sex ratio during the years. There are no considerable population density changes for Hemerodromia unilineata during the years.
