Abstract

Glavni je cilj ovog istraživanja bio modelirati potencijalnu rasprostranjenost četiriju vrsta roda Plecotus u Hrvatskoj, ispitati razlike u njihovim ekološkim nišama i odrediti status ugroženosti u Hrvatskoj. Za izradu prediktivnih modela rasprostranjenosti korištena je analiza čimbenika ekološke niše (ENFA) i metoda maksimalne entropije (Maxent). Za usporedbu ekoloških niša istraživanih vrsta korišten je softver ENMTools. Vrsta P. auritus preferira šumska staništa na višim nadmorskim visinama i nižu ljetnu temperaturu. Vrsta P. austriacus vezana je za antropogena staništa, a izbjegava šumska staništa. Vrsta P. kolombatovici preferira šumska staništa i visoku ljetnu temperaturu. Vrsta P. macrobullaris preferira hladnija i vlažnija staništa na višim nadmorskim visinama. Vrsta P. macrobullaris ima najširu ekološku nišu, a jasno najužu ekološku nišu od svih četiriju istraživanih vrsta ima vrsta P. kolombatovici. Najveće je preklapanje ekoloških niša između vrsta P. macrobullaris i P. auritus. Najmanje se preklapaju ekološke niše vrsta P. auritus i P. kolombatovici. Za sve četiri vrste predloženi su novi statusi ugroženosti.

Abstract (english)

The main aim of this study was to model the potential distribution of four Plecotus species in Croatia, examine the differences in their ecological niches and determine their conservation status in Croatia. The predictive models were built using the Ecological Niche Factor Analysis (ENFA) and the maximum entropy modelling method (Maxent), while the studied species’ ecological niches were compared by using the ENMTools software. The species P. auritus
prefers forest habitats at higher altitudes and a lower summer temperature. P. austriacus is tied to anthropogenic habitats and avoids forest habitats. P. kolombatovici prefers forest habitats and high summer temperature. P. macrobullaris prefers cooler and humid habitats at higher altitudes. P. macrobullaris occupies the widest ecological niche, while by far the narrowest niche of all four studied species belongs to P. kolombatovici. The largest overlap of ecological niches is between P. macrobullaris and P. auritus, while the smallest niche overlap can be found between P. auritus and P. kolombatovici. New conservation statuses were suggested for all four species.
