Abstract

Ravnokrilci (Orthoptera) su red kukaca koji obuhvaća podredove skakavaca (Caelifera) i zrikavaca (Ensifera).
Radi se o ekološki izuzetno važnoj skupini, što je čini jasnim ciljem istraživanja. Dinara i Svilaja su planine koje
pripadaju dinarskoj regiji Hrvatske koja sadrži veliki broj raznolikih lokaliteta te kao takva podržava veliki broj
vrsta ravnokrilaca. Ciljevi ovog rada bili su: popisati raznolikost ravnokrilaca Dinare i Svilaje uz procjenu
brojnosti vrsta na različitim lokalitetima, korelirati određene vrste sa lokalitetima te ponuditi pregled
rasprostranjenosti, učestalosti i bioakustike dinaridskog endema Rammeihippus dinaricus (Götz, 1970). Ovim
radom daje se nadopunjeni popis vrsta ravnokrilaca Dinare i prvi popis vrsta Svilaje. Gustoće populacija
procijenjene su izravno na terenu korištenjem metode 1-3-7 te su ti podaci korišteni za provedbu PCA i heatmap
analiza. Heatmap analizaom dobiveni su dendrogrami koji slične lokalitete grupiraju zajedno. Te grupe
interpretirane su kao visinsko-klimatske zone, što je podržano i literaturom. Korelaciju vrsta preko lokaliteta
nemoguće je napraviti zbog manjeg broja lokaliteta u odnosu na broj vrsta. Kao posebna cjelina obrađena je
distribucija vrste Rammeihippus dinaricus, kao i njena morfološka varijabilnost i pjev.

Abstract (english)

The insect order Orthoptera encompasses grasshoppers (Caelifera) and crickets (Ensifera). This is an
ecologically important taxon, which makes it the goal of many research efforts. Dinara and Svilaja are mountains
belonging to the Dinaric region of Croatia, a region rich in species due to the diverse localities it contains. The
aims of this thesis were to: record the diversity of Orthoptera on Dinara and Svilaja Mountains together with
abundance estimations for different localities, correlate species with localities, and give an overview of
distribution, abundance and distribution of a species endemic to Dinarides, Rammeihippus dinaricus (Götz,
1970). This thesis offers an updated checklist of Orthoptera for Dinara Mt. and the first checklist for Svilaja Mt.
Population densities were estimated in the field using the 1-3-7 method, and the collected data was used in
conducting the PCA and heatmap analyses. The heatmap analysis produced cladograms that relate localities to
each other by similarity. The groups on the cladograms are interpreted to represent regions of altitudinal
zonation, which is supported by literature. Considering the small number of sampled localities as opposed to the
number of species, the correlation of species by localities could not be performed. A special segment of this
thesis is dedicated to the distribution, morphological variability, and song of Rammeihippus dinaricus.
