Cilj istra\u017eivanja bio je utvr\u0111ivanje stanja populacije velikouhog \u0161i\u0161mi\u0161a Myotis bechsteinii<\/em>, odnosno njegove prisutnosti, i istra\u017eivanje podzemnih objekata kao potencijalnih skloni\u0161ta \u0161i\u0161mi\u0161a. Terenska istra\u017eivanja i obrada i organizacija podataka provedene su standardnim metodama. Zahvaljuju\u0107i kombiniranju metoda pregleda podzemnih skloni\u0161ta s pregledom nadzemnih skloni\u0161ta, uzorkovanjem mre\u017eama i snimanjem glasanja potvr\u0111eno je 18 od najmanje 22 vrsta \u0161i\u0161mi\u0161a, koliko je o\u010dekivano da \u0107e biti prisutno.<\/p>\n Vrsta M. bechsteinii<\/em> kao skloni\u0161te naj\u010de\u0161\u0107e koristi rupe i pukotine u stablima, a njezinim klju\u010dnim lovnim stani\u0161tem smatraju se stare sastojine listopadnih i bogato strukturiranih \u0161uma s \u010distinama. Istra\u017eivanja provedena u okviru ovog projekta prva su ciljana istra\u017eivanja u svrhu utvr\u0111ivanja statusa ove vrste na \u0161irem podru\u010dju NP \u201eKrka\u201c. U lipnju i srpnju 2024. zabilje\u017eena je prisutnost jednog mu\u017ejaka u nekori\u0161tenoj zgradi vodocrpili\u0161ta Torak, koja je utvr\u0111ena i kao povremeno skloni\u0161te pojedina\u010dnih jedinki vrsta M. emarginatus<\/em>, R. hipposideros<\/em> i R. ferrumequinum<\/em>. Kao zna\u010dajna stani\u0161ta za vrstu isti\u010du se starije sastojine \u0161ume hrasta medunca i bijelog graba i mije\u0161ane poplavne \u0161ume. Istra\u017eivanjem provedenim 2024. godine vrsta je potvr\u0111ena uzorkovanjem mre\u017eama na trima lokalitetima unutar ili u blizini navedenih tipova stani\u0161ta. Prilikom daljnjih istra\u017eivanja potrebno je utvrditi dostupnost tih stani\u0161ta i utvrditi i druge lokalitete na kojima je vrsta prisutna. Prema poznatoj ekologiji vrste, mu\u017ejaci tijekom ljeta \u017eive solitarno, a porodiljne kolonije naj\u010de\u0161\u0107e se sastoje od deset do pedeset \u017eenki, koje \u010desto mijenjanju skloni\u0161ta. Prema rezultatima dosada\u0161njih istra\u017eivanja, mogu\u0107e je da su na istra\u017eivanom podru\u010dju \u010de\u0161\u0107e prisutni pojedina\u010dni mu\u017ejaci, dok je daljnjim istra\u017eivanjima potrebno utvrditi koriste li \u0161ire podru\u010dje NP \u201eKrka\u201c i trudne \u017eenke i \u017eenke s mladima.<\/p>\n Istra\u017eena su i potencijalna podzemna skloni\u0161ta \u0161i\u0161mi\u0161a. Zabilje\u017eeno je \u0161est skloni\u0161ta pojedina\u010dnih jedinki vrsta R. ferrumequinum<\/em> i R. hipposideros<\/em> i \u010detiri nova va\u017ena skloni\u0161ta (Stara jametina, Golubnja\u010da na Liveru, Mi\u0161ja pe\u0107ina i \u0160pilja Buhara) u kojima je potvr\u0111ena prisutnost sedam od devet ciljnih vrsta o\u010duvanja. Podru\u010dje ju\u017eno od manastira sv. Arhan\u0111ela do Skradinskog buka i dalje ostaje nedovoljno neistra\u017eeno zbog te\u017ee dostupnosti, te je vrlo vjerojatno da se na \u0161irem podru\u010dju NP \u201eKrka\u201c nalazi jo\u0161 zna\u010dajnih skloni\u0161ta za \u0161i\u0161mi\u0161e.<\/p>\n \u00a0<\/p>\n <\/p>\n [\/hr]<\/p>\n [en] The aim of the research was to determine the population status of the Bechstein’s bat Myotis bechsteinii<\/em>, or rather its presence, and to investigate underground structures as potential bat shelters. All the field research, data processing, and organization of information were conducted using standard methods. By combining methods, using underground habitat surveys with above-ground habitat surveys, network sampling, and vocalization recording, the presence of 18 out of the at least 22 expected bat species was confirmed.<\/p>\n The Bechstein’s bat species most often uses holes and cracks in trees for shelter, and its key hunting habitat is considered to be old stands of deciduous and richly structured forests with clearings. The investigated conducted within this project is the first targeted research aimed at determining the status of this species in the broader area of \u200b\u200bthe Krka National Park. In June and July of 2024, the presence of one male was recorded in the unused building of the Torak Water Pumping Station, which was also identified as an occasional shelter for single individuals of the species M. emarginatus<\/em>, R. hipposideros<\/em>, and R. ferrumequinum<\/em>. Important habitats for the species include older stands of downy oak and Oriental hornbeam forests and mixed floodplain woods. In 2024, the presence of the species was confirmed by sampling with nets at three locations within or near the aforementioned habitat types. Further research is needed to determine the availability of these habitats and to identify other sites where the species is present. According to the known ecology of the species, the males live solitary lives during the summer, while birthing colonies usually consist of 10 to 50 females who frequently change shelters. According to the results of research to the present, it is possible that individual males are more frequently present in the research area, while further research is needed to determine whether pregnant females and females with young also utilize the broader area of \u200b\u200bthe Krka National Park.<\/p>\n Potential underground bat habitats were also investigated. Six shelters of single individuals of the species R. ferrumequinum<\/em> and R. hipposideros<\/em> were recorded, as well as four new important bat roosts (Stara jametina, Golubnja\u010da na Liveru, Mi\u0161ja pe\u0107ina, and \u0160pilja Buhara), all caves in which the presence of seven out of nine conservation target species was confirmed. The area south of the Monastery of St. Archangel to the Skradinski buk Waterfall remains insufficiently explored due to difficulties with accessibility, and it is very likely that other significant bat habitats exist in the broader area of \u200b\u200bthe Krka National Park.<\/p>\n <\/p>\n <\/p>\n Tijekom 2024. godine tvrtka Geonatura d.o.o. provela je istra\u017eivanje \u0161i\u0161mi\u0161a na podru\u010dju ekolo\u0161ke mre\u017ee HR2000918 \u0160ire podru\u010dje NP Krka<\/p>\n","protected":false},"author":2,"featured_media":11106,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[44],"tags":[],"class_list":["post-11104","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-research"],"_links":{"self":[{"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/posts\/11104","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/comments?post=11104"}],"version-history":[{"count":4,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/posts\/11104\/revisions"}],"predecessor-version":[{"id":14107,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/posts\/11104\/revisions\/14107"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/media\/11106"}],"wp:attachment":[{"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/media?parent=11104"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/categories?post=11104"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/tags?post=11104"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![](\"https:\/\/npkrka.hr\/wp-content\/uploads\/MR00057-GN_MKRC_E-ser-7-scaled.jpg\")
