Abstract

U istraživanjima je analizirana rasprostranjenost velikouhog šišmiša (Myotis bechsteinii),
rijetke i važne indikatorske vrste za očuvanost šumskih staništa, na području kontinentalne
biogeografske regije u Hrvatskoj. Intenzivnim terenskim istraživanjima zabilježeno je 12 novih
lokaliteta, čime je značajno povećano poznavanje areala rasprostranjenosti vrste. Analiza
aktivnosti vrste pokazala je da koristi mozaičnu strukturu staništa, ali s dominantnim udjelom
listopadnih šumskih staništa, unutar kojih dominiraju sastojine starih stabala bukve (63 %) i
hrasta (32 %). MaxEnt model povoljnosti staništa identificirao je temperaturne bioklimatske
varijable kao značajnije od oborinskih, uz značajan doprinos i blizine vodenih staništa.
Podudaranje nezavisnih podataka o prisutnosti vrste s višim kategorijama modelirane
povoljnosti bilo je dobro, potvrđujući upotrebljivost modela. Ustanovljena je i podudarnost
viših kategorija povoljnosti modela s terenski istraženim lokalitetima prisutnosti vrste u
najvećem udjelu bukovih i hrastovih šuma. Predložene su mjere gospodarenja šumama s ciljem
očuvanja populacija šišmiša vezanih uz šumska staništa.

Abstract (english)

This thesis is a result of research and analysis of the distribution of the Bechstein’s bat (Myotis
bechsteinii), a rare and important indicator species for the conservation of forest habitats, in the
continental biogeographic region in Croatia. Altogether 12 new localities were recorded
through intensive field research, which significantly increased the knowledge of the distribution
of the species. The analysis of the species activity showed that it uses a mosaic habitat structure,
but with a dominant share of deciduous forest habitats, within which stands of old beech (63%)
and oak trees (32%) dominate. The MaxEnt habitat suitability model identified temperature
bioclimatic variables as more significant than precipitation, with a significant contribution of
the proximity to water habitats. Matching the independent species presence data to higher
categories of modelled suitability was good, confirming the replicability of the model. Higher
suitability values of the model also matched with the researched localities for the presence of
the species, mainly in the beech and oak forests. Forest management measures were proposed
to achieve conservation of the bat populations connected to forest habitats.
