Izvleček. Med 22. in 31. julijem 1998 je bilo na 13 lokalitetah zahodne Slovenije nabranih 114 vrst pajkov. Trije rodovi in enajst vrst je prvič zabeleženih na ozemlju Slovenije. Rezultat četrtega v nizu poskusov ocenjevanja vrstnega bogastva pajkov slovenskih gozdov pri vasi Črnice v Vipavski dolini kaže, da je preiskovani gozd vrstno precej bogat (85-107 vrst).

Abstract. A list of 114 spider species collected between 22 and 31 July 1998 at 13 localities of western Slovenia is given. Three genera and eleven species are new to the fa una of Slovenia. A result of an investigation into spider species richness, the fourth in a series of such experiments in Slovenian forests, indicates that the surveyed forest near the village Črnice in Vipava valley is rather rich in species (85-107 species).

Izvleček. Prispevek podaja rezultate lepidopterološke skupine na Raziskovalnem taboru študentov biologije Šempas 98'. Na 34 lokalitetah je bilo med 23.7 in 31.7.1998 opaženih 92 vrst metuljev dnevnikov (Rhopalocera) od katerih je 9 vrst vključenih v Atlas ogroženih vrst metuljev Slovenije. Poleg spoznavanja ekoloških zahtev posameznih vrst in popisovanja je bila narejena tudi favnistična primerjava med geografsko in geološko dobro ločenimi deli obravnavanga območja. Najbolj bogata je favna dnevnih metuljev na pobočjih severno od Vipavske doline (pobočja Sabotina, Čavna, Nanosa in nad Ajdovščino), kjer se mešajo južnoevropski in severnoevropski favnistični elementi. Najbolj ogrožen habitatni tip so nižinski vlažni in močvirni travniki v Vipavski dolini.

Abstract. Results of the work of the group for lepidopterology at Student Research Camp Šempas 98' are presented. Altogether 92 species of butterflies were recorded between 23.7.1998 and 31.7.1998 from 34 localities. Nine recorded species are included in Atlas of endangered butterflies of Slovenia. Apart from species registration and characterisation of their ecological requirements, a faunistic comparison between geographically and geologically well defined areas was done. The most diverse butterfly fauna has been observed in the area north of Vipavska dolina where South-European and north-European faunistic elements meet. The most endangered habitats are lowland wet or marsh meadows at the bottom of Vipavska dolina.

Izvleček. Prispevek predstavlja rezultate dela lepidopterološke skupine na Raziskovalnem taboru študentov biologije Šalovci 99' in opazovanj v letu 1999. Na 60 lokalitetah, vštevši tudi posamična opazovanja, je bilo 29.5. 1999 ter med 22.7. in 29.7.1999 skupno opaženih 75 vrst dnevnih metuljev (Rhopalocera). Glede na prejšnje objave je bilo za to regijo najdenih 7 novih vrst, kjer je tako skupno registriranih 109 vrst. Poleg tega so bile potrjene najdbe dveh vrst, ki sta bili navedeni v literaturi brez natančnih podatkov. Skupaj je bilo zabeleženo 9 vrst, ki so vključene v Atlas ogroženih vrst metuljev Slovenije. Mednje sodi tudi vrsta Maculinea alcon Schiff., za katero so bile narejene ocene vitalnosti populacij na podlagi štetja jajčec. Nekatere izmed drugod v Sloveniji ogroženih vrst so na Goričkem zaradi ekstenzivne rabe kmetijskih površin še vedno splošno razširjene in pogoste. To velja predvsem za modrine in pisančke, ki so vezani na vlažne travnike. Presenetljive so predvsem najdbe nekaterih toploljubnih vrst, ki se na Goričkem večinoma pojavljajo zelo lokalno. Zaradi vrstne pestrosti in zadnjih območij sklenjene naselitve nekaterih v Sloveniji močno ogroženih vrst je celovita zaščita Goričkega nujno potrebna.

Abstract. Results of the fieldwork of the group for lepidopterology at Student Research Camp Šalovci 99' and previous observations in year 1999 are presented. Altogether 75 species of butterflies were recorded on 29.5.1999 and between 22.7.1999 and 29.7.1999 from 60 localities including individual observations. Taking into account the published data 7 new species for Goricko were observed raising the number to total of 109 registered species. Apart from that findings of two species, previously listed without exact locality, were confirmed. Altogether 9 species included in the Atlas of endangered butterfly species of Slovenia were sighted. The vitality of population of Maculinea alcon Schiff have been estimated by egg counts. Some of the Slovenian endangered butterflies form families Lycaenidae and Nymphalidae are still common at Goričko, probably due to extensive land use. Most surprising were the findings of thermophylous species that occur mostly locally at Goričko. Because of species richness and last areas of continuos distribution of some highly endangered species in Slovenia, complete protection of Goričko is required.

V prispevku so predstavljeni rezultati dela botanične skupine na mladinskem raziskovalnem taboru Dolenja vas 1998, ki je potekal v času od 3. do 10. 7. 1998 v Dolenji vasi pri Ribnici na Dolenjskem. Skupina je po metodi srednjeevropskega kartiranja flore popisovala višje rastline v dveh kvadrantih: 0254/4 in 0254/3. Obravnavane so naslednje zanimivejše vrste: Leonurus cardiaca, Dactylorhiza maculata ssp. transsilvanica, Vulpia ciliata, Senecio paludosus, Senecio aquaticus, Sisyrinchium bermudiana in Tanacetum parthenium.

Abstract. During the Youth Research Camp Dolenja vas '98 in the begining of July 1998 some floristical investigations were performed in south-western part of Dolenjska region. The floristic research was based on mapping vascular plant in two 'quadrants' of MTB grid, covering the valley of the Ribnica river and its sorroundings. The article discusses the results of this research and presents some of the most interesting recorded species: Leonurus cardiaca , Dactylorhiza maculata ssp. transsilvanica, Vulpia ciliata, Senecio paludosus, Senecio aquaticus, Sisyrinchium bermudiana and Tanacetum parthenium.

Izvleček. Leta 1995 je bil v Savi pri Termah Catež najden za Slovenijo nov takson pijavke, katerega znacilnosti sovpadajo z vrsto Glossiphonia slovaca Košel 1973. Taksonomija te vrste in njenega sestrskega taksona G. paludosa (Carena 1824) še ni povsem razjasnjena. Večkrat so pod slednjim imenom obravnavali dve nesorodni vrsti, hkrati pa razlikovanje med sestrskima taksonoma ni bilo zadovoljivo razdelano. Avtor se je na podlagi molekularnih in biogeografskih razlik odločil, da je smiselno ločevati obe vrsti. Sava pri Čatežu je s sedmimi vrstami pijavk ena najbogatejših lokalitet v Sloveniji. Za ta odsek Save je predvidena zajezitev za hidroenergetske potrebe, kar bi uničilo habitat nekaterih v Sloveniji zelo redkih pijavk.

Abstract. In 1995 a leech taxon new to Slovenia has been found in the river Sava at Žatež. It displays the characteristics of the species Glossiphonia slovaca (Košel 1973). The taxonomy of this species and its sister taxon G. paludosa (Carena 1824) has been controversial. The latter name has been used for two remotely related species, whereas the differentiation between the sister taxa has not been sufficiently elaborated. However, molecular and biogeographic differences between the two sister taxa seem to justify their status as distinct species. The Sava river at Čatež is inhabited by at least seven leech species, some of which are very scarce in Slovenia. The site is threatened by damming for hydroelectric power plants.

Izvleček. Podan je seznam 32 vrst kačjih pastirjev, zabeleženih na 27 najdiščih med leti 1994 in 2000. Tri vrste, rdeči voščenec Ceriagrion tenellum (de Villers), modroriti spremljevalec Anax parthenope (Sélys) in črni ploščec Libellula fulva Müller, so nove za obravnavano območje. Na kratko so predstavljene tudi najdbe koščičnega škratca Coenagrion ornatum (Sélys), prodnega paškratca Cercion lindenii (Sélys), velikega studenčarja Cordulegaster heros Theischinger, pegastega lesketnika Somatochlora flavomaculata (Vander Linden) in malega modrača Orthetrum c. coerulescens(Fabricius), ki zaslužijo pozornost z zoogeografskega ali naravovarstvega stališča. Za Vipavsko dolino s širšo okolico je sestavljen seznam 44 doslej zabeleženih vrst kačjih pastirjev, predstavljena pa je tudi odonatološka bibliografija za to območje.

Abstract. An annotated list of 32 dragonfly species collected at 27 localities during the 1994-2000 period is given. Three species, viz. Ceriagrion tenellum (de Villers), Anax parthenope (Sélys) and Libellula fulva Müller, are new for the investigated area. The records of Coenagrion ornatum (Sélys), Cercion lindenii (Sélys), Cordulegaster heros Theischinger, Somatochlora flavomaculata (Vander Linden) and Orthetrum c. coerulescens (Fabricius) are also briefly commented as they deserve attention from zoogeographical or nature conservation point of view. A list of 44 dragonfly species, hereto reported from the Vipava valley with its surroundings, is compiled and an odonatological bibliography of the investigated area is presented.
