In our contribution we report on the local host ants of two threatened and protected butterfly species, the scarce large blue (Phengaris teleius) and the dusky large blue (P. nausithous) at Goričko ...(NE Slovenia), which hosts one of the largest and the most important metapopulation for both species of large blues in Slovenia. Larvae of both species are developing in Myrmica ant nests and different ant species may be used as larval hosts in different parts of the species range. During our study, seven species of potential host ants of the genus Myrmica were found at 12 selected sampling sites. A total of 142 ant nests were examined for the presence of Phengaris larvae. Larvae of P. teleius were found in 25 nests of three ant species: M. scabrinodis, M. rubra and M. gallienii, while larvae of P. nausithous were found in 9 nests, all of M. rubra. The results of the present study provide the first insight into the local host ants of the two Phengaris species in Slovenia and could serve as an important source for active conservation of both species in Slovenia.
The Asian clam (Corbicula fluminea) is considered one of the most invasive freshwater bivalves in the world. It has been introduced to several European countries. During the field surveys conducted ...in August 2018, a total of 61 specimens of the Asian clam were found along the Drava River between Ormož and Središče ob Dravi in Northeast Slovenia. These are the first records of this invasive species’ occurrence in Slovenia.
In this study we examined the population of the European pond turtle (Emys orbicularis) in the Prilipe oxbow lakes along the Sava River. The species’ sex and age structure were estimated as well its ...population size. In the area of approximately 5.9 ha of water surface, 3 individuals were found in 2008 and 70 in 2019, when a more detailed survey was conducted. The population size was estimated at 125 individuals. According to the age structure and confirmed reproduction, the population is recognized as viable. The main threats to the survival of European pond turtles in this area are potential direct interventions into habitat as well as indirect changes such as alterations in flood regime or in groundwater level. Additionally it is threatened by the invasive red-eared slider (Trachemys scripta elegans), the reproduction of which was also confirmed during our survey. Although the studied area meets all conditions for the establishment of the Natura 2000 site, it was not included in this network in 2003 due to lack of knowledge as far as this species was concerned.
V Beli krajini je močvirska sklednica glede na starejše podatke splošno razširjena, toda novejših podatkov o razširjenosti za to vrsto ni, kaj šele podatkov o njeni ekologiji. Med letoma 2008 in 2012 ...smo raziskali ekologijo, stanje populacije in razširjenost te vrste v Beli krajini na stoječih vodah in izvirih. Vrsta je bila potrjena v primarnih in sekundarnih vodnih habitatih na štirih večjih območjih. Od 48 ujetih želv jih 40 % spada med osebke, stare do deset let. Razmnoževanje smo potrdili na petih lokacijah (Prilozje, Zjot, Golek, mrtvica Obrha, Nerajec). V kalu Golek in Gornjem kalu smo zabeležili mesta, kjer želve odlagajo jajca. Na treh lokacijah smo potrdili tudi tujerodno rdečevratko in na eni rumenovratko. Na podlagi števila osebkov, starostne sestave in potrjenega razmnoževanja je populacija v zgornjem toku reke Lahinje najbolj vitalna, sledijo mrtvice Obrha pri Metliki, okolica naselja Prilozje in okolica Hrasta. V prispevku so podani tudi naravovarstveni pogledi in predlogi za razširitev omrežja NATURA 2000.
A checklist of the Microlepidoptera species recorded in Slovenia is presented. Each entry is accompanied by complete references, and remarks where appropriate. Until now, the data on ...Microlepidopteran fauna of Slovenia have not been compiled, with the existing information scattered in literature, museums and private collections throughout Europe. The present checklist is based on records extracted from 290 literature sources published from 1763 (Scopoli) to present. In total, 1645 species from 56 families are listed.
V prispevku predstavljamo 113 novih, naključno zbranih podatkov o razširjenosti hromega volnoritca Eriogaster catax (Linnaeus, 1758) v Sloveniji na 78 različnih lokacijah. Poznavanje razširjenosti ...vrste smo s 44 povečali na 56 UTM kvadratov. Največ podatkov je s Primorske. Nova nahajališča vrste so predvsem iz severovzhodne Slovenije: ob reki Ledavi, Muri in Dravi; v vzhodni Sloveniji na Kozjanskem in ob spodnjem toku reke Save. Vrsta je prvič najdena tudi v Beli krajini. Izboljšali smo poznavanje razširjenosti vrste na Notranjskem (Cerkniško jezero in Pivška jezera), na obronkih Nanosa in v dolini Dragonje. Za analizo fenologije in vertikalne razširjenosti vrste smo uporabili vse podatke. Gosenice smo opazovali od konca marca do sredine junija, odrasle osebke pa od sredine septembra do začetka novembra. Po doslej znanih podatkih se hromi volnoritec v Sloveniji pojavlja med 0 in 960 m nadmorske višine. Mediana višinske razporeditve podatkov je pri 258 m n. m., polovica vseh podatkov pa je razporejena v pasu od 166 do 420 m n. m. Ocenjujemo, da je poznavanje razširjenosti vrste v Sloveniji še zmeraj nezadovoljivo.
Na podlagi rezultatov dveh metodološko različnih načinov zbiranja podatkov je prikazana razširjenost ogrožene vrste Unio crassus na Goričkem, ki velja za malakološko manj raziskano območje Slovenije. ...Ribe igrajo pomembno vlogo v razvoju te školjke, zato je lokalitetam školjk dodan tudi seznam ribjih vrst, ki živijo na teh lokalitetah.
V članku predstavljamo 11 novih opažanj in literaturne podatke o pojavljanju navadne česnovke (Pelobates fuscus) v Podravju. Najdišča v Podravju pokrivajo severni rob areala navadne česnovke v dolini ...reke Drave. Novi podatki so z lokacij, kjer je bila navadna česnovka že najdena (Rački ribniki, Ormoške lagune), in tudi z novih lokacij (Podvinci, Kidričevo). Novi podatki nakazujejo, da je navadna česnovka v Podravju pogostejša, kot je veljalo doslej. V celotnem porečju Drave je še vedno precej drugih potencialno primernih okolij za navadno česnovko, kot so npr. mrtvice, glinokopi, ribniki in gramoznice.
Ten new observations of the European pond turtle Emys orbicularis (Linnaeus, 1758) in the Podravje region are presented. One observation is fairly old, while the others have been made in the last six ...years. Most of the data are just random observations and do not give a complete overview of the species distribution in the Podravje region. New data suggest that the European pond turtle is more abundant in the Drava River basin than previously known. Distribution and population size of the species in the Drava River basin still remain to be investigated in detail and not only at the Natura 2000 Drava site, especially in the areas of potential habitats prior to planning any new activities.
The species' localities in the Podravje region constitute the northern edge of its range in the Drava river basin. There are many other potential well suited habitats for the common spadefoot, like ...oxbow lakes, gravel and clay pits, ponds and fishponds, in the Podravje region. Key words: common spadefoot, Pelobates fuscus, Drava River basin, Slovenia, Annex IV, Habitats Directive Uvod Navadna česnovka (Pelobates fuscus) sodi med najbolj redke vrste dvoživk v Sloveniji, razmeroma pogosta je le ob reki Muri (Cipot 2005).
