Izvleček. V članku so predstavljeni rezultati popisa netopirjev, napravljenega v okolici Turjaka med julijem 1999 in januarjem 2001. S pregledi prebivališč, lova z mrežo in predvsem z ultrazvočnim detektorjem je bilo na raziskovanem obmocju odkritih najmanj 15 netopirskih vrst. Najpogosteje zaznana vrsta je bila Pipistrellus pipistrellus, odkrite pa so bile v Sloveniji redko opažene vrste - Rhinolophus euryale, Myotis natterreri, Myotis emarginatus, Pipistrellus pygmaeus in Nyctalus leisleri. Varstveno so pomembne najdbe porodniških kolonij vrste Rhinolophus hipposideros.

Abstract. A survey of the bat fauna in the vicinity of Turjak (south central Slovenia) - Results of the survey carried out in the vicinity of Turjak (Dolenjska, Slovenia) between July 1999 and January 2001 are presented in the article. At least fifteen species were recorded with the monitoring of potential roost sites, mist netting and the use of heterodyning bat detectors. Pipistrellus pipistrellus was most commonly observed species. Species not frequently found in Slovenia - Rhinolophus euryale, Myotis natterreri, Myotis emarginatus, Pipistrellus pygmaeus and Nyctalus leisleri - were also detected. Findings of Rhinolophus hipposideros nursery roosts are of particular conservation concern.

Izvleček. Radensko polje je eno večjih območij ekstenzivno rabljenih vlažnih travnikov v osrednji Sloveniji. V letu 2000 sva opravila naravovarstveno vrednotenje širšega območja Radenskega polja na podlagi favne dnevnih metuljev. Naravovarstveno so gotovo najpomembnejše velike populacije vrst Maculinea alcon, Euphydryas aurinia in Pyrgus armoricanus, medtem ko se zelo ogrožena vrsta Carcharodus flocciferus pojavlja bolj lokalno v severnem delu polja. Na podlagi ugotovljenega števila vrst in razširjenosti ogroženih vrst predlagava dve območji varstva dnevnih metuljev na nivoju naravnih rezervatov, za celotno Radensko polje pa razglasitev za širše zavarovano območje kot krajinski park.

Abstract. Nature conservation value of Radensko polje near Grosuplje based on the Inventory of Butterflies (Lepidoptera: Rhopalocera) - Radensko polje is one of the largest areas of extensively used wet meadows in central Slovenia. In 2000, we surveyed the nature conservation value of this area based on distribution of the butterfly fauna. The presence of strong populations of Maculinea alcon, Euphydryas aurinia and Pyrgus armoricanus pointed out a very high conservation value of the surveyed area. Equally important is the presence of locally distributed and highly threatened Carcharodus flocciferus in the northern part of the polje. In view of the evaluation of the endangered species distribution and the number of species recorded at the sites we propose two districts to be given the status of nature reserves, while the entire Radensko polje should be protected as a landscape park.

Abstract. A contribution to the knowledge of the distribution of diurnal butterflies (Lepidoptera: Rhopalocera) in the Notranjska region - Field data on diurnal butterfly species collected during the Youth Reasearch Camp Stari trg pri Ložu 2000 are presented. During 15 th and 23 rd June 2000, 48 species of diurnal butterflies from 6 families were recorded at 22 localities in the area of Loško and Babno poljes, the surroundings of Cerkniško jezero and on Bloška planota. Among the observed species, one is included in the Anex II of the Bern Convention, 2 in the Red Data Book of European Butterfiles, 3 in the Atlas of Endangered Diurnal Butterflies of Slovenia, and 7 on the Red List of Endangered Butterflies (Macrolepidoptera) in Slovenia (Dinaric region). Data for Lycaena alciphron in the reasearch area is published for the first time. The wide distribution of Lopinga achine, a vulnerable species in Europe, is of great conservation value.

Abstract. The composition of inflorescence visitors of two Euphorbia species is presented and their role as possible pollinators is discussed. Pollinators of Euphorbia nicaeensis were studied in the Slovene Karst, near Sežana, and pollinators of E. lucida on the plants growing on the shores of the intermittent Lake Cerknica (both SW Slovenia) in the middle of June 2000. The comparison between abundance of different animals (especially insects) visiting both Euphorbias is presented.

Ob pregledu zoološke zbirke Oddelka za biologijo Biotehniške fakultete Univerze v Ljubljani in materiala, nabranega v zadnjih treh letih, je bilo odkritih 21 vrst pajkov skakačev (Salticidae), ki doslej še niso bile najdene v Sloveniji. To so: Asinellus festivus (C.L. Koch, 1834), Euophrys herbigrada (Simon, 1871), Evarcha michailoviLogunov, 1992, Chalcoscirtus infimus (Simon, 1868), Heliophanus aeneus (Hahn, 1932), H. dubius C.L. Koch, 1835, H. kochii Simon, 1868, H. melinus L. Koch, 1867, H. patagiatus Thorell, 1875, H. tribulosus Simon, 1868, Icius hamatus (C.L. Koch, 1846), Marpissa pomatia (Walckenaer, 1802), Mendoza canestrinii (Ninni, 1868), Neon rayi (Simon, 1875), Pellenes nigrociliatus (Simon, 1875), Pellenes seriatus (Thorell, 1875), Pseudicius encarpatus (Walckenaer, 1802), Pseudeuophrys erratica (Walckenaer, 1826), Synagales hilarulus (C.L. Koch, 1846), Synagales venator (Lucas, 1836) in Talavera thorelli (Kluczynski, 1891). Visoko število novo odkritih vrst kaže na slabo raziskanost favne pajkov v Sloveniji.

Najdenih je bilo 12 vrst netopirjev, od tega 3 vrste v Belojači in 11 v glavnini raziskovalnega območja. Netopirje smo popisovali v njihovih prebivališčih in na mestih, kjer se prehranjujejo. V cerkvah in gradovih je bilo najdenih 5 porodniških kolonij. 3 so pripadale malim podkovnjakom Rhinolophus hipposideros, po 1 pa poznemu Eptesicus serotinus in navadnemu netopirju Myotis myotis. Dokumentirano je izginotje slednjih dveh porodniških kolonij zaradi prenove strehe. Navedena so tudi nekatera ekološka opažanja, med katerimi je zanimivo opazovanje goža Elaphe longissima v porodniški koloniji malega podkovnjaka. Možnost plenilskega odnosa ni izključena. Na koncu so podana nekatera priporočila za varstvo netopirjev.

Abstract. Summer records of bats in the hilly area W of the central part of the Sotla river and from Belojača Cave in Haloze are presented. 12 species were found, 3 in Belojača and 11 in the main part of the study area. Bats were observed at their roosts and feeding grounds. 5 nursery colonies were found in churches and castles. 3 belonged to the lesser horseshoe bat Rhinolophus hipposideros, 1 to the serotine Eptesicus serotinus and 1 to the greater mouse-eared bat Myotis myotis. The disappearance of the latter two nursery colonies on account of roof renovation is documented. Some ecological data are also mentioned, including an interesting observation of Aesculapian snake Elaphe longissima in the nursery of the lesser horseshoe bat. The possibility of predation can not be excluded. At the end some recommendations for bat conservation are given.
