Abstract

Istraživanje mrava provedeno je na području planine Dinara i rijeke Cetine u sklopu BIUS-ovog terena 2012. godine. Metodom lovnih posuda, mini-winklwra, standardiziranog ručnog sakupljanja i beatinga zabilježeno je 43 vrste mrava. Na temelju brojnosti vrsta otkrivene su razlike u njihovom sastavu između visinskih zona na Dinari te se pokazalo kako je zona s najvećom raznolikošću vrsta na sredini visinskog gradijenta. Od staništa prisutnih na Dinari najveća brojnost vrsta pronađena je na travnjačkim staništima na kojima je zapažena izrazita dominacija mrava iz roda Formica. Istraživanje prema funkcionalnim skupinama pokazalo je kako mali udio oportunističkih vrsta na Dinari ukazuje na dobru kvalitetu staništa, za razliku područja uz rijeku Cetine gdje je antropogena aktivnost najveća i broj oportunističkih vrsta raste.

Abstract (english)

An ant inventory was conducted on Dinara Mt. and Cetina river in 2012. The myrmecofauna was studied using pitfall traps, mini-winklers, standardized hand collecting and beating methods. The total of 43 species of ants were recorded. The distribution of ants among elevational gradient showed that the peak in ant species richness were at the middle of the gradient instead at the bottom of it. The habitat analysis showed that the greatest species richness was found on grassland habitats. Genus Formica was the dominant genus on that type of habitats. Exploring the functional groups of Dinara Mt. and Cetina river the largest proportion of opportunistic species were found near Cetina river where anthropogenic activity is higher than rest of the study area, contrary to habitats on Dinara with smaller number of opportunistic species, hence the higher quality of habitats.
