Abstract

Na sastav i strukturu zajednica vodenih kukaca utječu različiti abiotički i biotički čimbenici.
Sedrene barijere se izdvajaju kao iznimno važna staništa zbog prisutnosti mnogih mikrostaništa i
velike produktivnosti. Ciljevi ovog istraživanja su utvrditi vremensku varijabilnost kroz promjene
u faunističkom sastavu i raznolikosti zajednice tulara, promjene u emergencijskim značajkama te
promjene u funkcionalnoj strukturi zajednice na sedrenoj barijeri Kozjak-Milanovac, u
Nacionalnom parku Plitvička jezera. U četrnaestogodišnjem istraživanju (2008.-2021.) su
prikupljani odrasli tulari pomoću emergencijskih klopki. Prikupljeno je 10346 jedinki tulara te je
zabilježeno 39 vrsta iz 12 porodica. Zabilježena je varijabilnost u brojnosti vrsta te u raznolikosti
kroz godine. U zajednici su zastupljene mnoge funkcionalne skupine, a najbrojniji su predatori i
pasivni procjeđivači. Zabilježena je i varijabilnost funkcionalne strukture zajednice tulara, što
odražava promjene u okolišu tijekom istraživanog razdoblja. Vrhunac emergencije zabilježen je u
ljetnim mjesecima tijekom cijelog istraživanja. Dominantne svojte imaju različite obrasce
emergencije, a posebno se izdvaja vrsta Neureclipsis bimaculata sa sinkroniziranim obrascem s
dva maksimuma. Rezultati naglašavaju važnost dugogodišnjih istraživanja za razumijevanje
ekologije zajednica i očuvanja bioraznolikosti specifičnih krških staništa.

Abstract (english)

The composition and structure of aquatic insect communities are influenced by various abiotic and
biotic factors. Tufa barriers are characterized by the presence of many microhabitats and high
productivity as very important habitats. The aims of this research were to determine temporal
variability through changes in the composition and diversity of the caddisflies community, changes
in emergence patterns, and in the functional structure of the community at the Kozjak-Milanovac
tufa barrier, in Plitvice Lakes National Park. During a fourteen-year study (2008-2021), adult
caddisflies were collected using emergence traps. A total of 10,346 caddisflies were collected,
representing 39 species from 12 families. High variability in species abundance and diversity was
observed over the years. The community included many functional groups, with predators and
passive filter-feeders being the most abundant. Variability in the functional structure of the
caddisfly community was also recorded, reflecting environmental changes during the study period.
Peak emergence was observed in the summer months throughout the entire study period. Dominant
species exhibited different emergence patterns, with Neureclipsis bimaculata standing out for its
synchronized pattern with two peaks. The results highlight the importance of long-term research
for understanding community ecology and preserving the biodiversity of specific karst habitats.
