Intraspecific variation in size along spatial and environmental gradients has been documented in many studies, and different hypotheses have been proposed to explain these patterns of geographic variation. We explored size variation in 4 island and 35 mainland samples of the Edible Dormouse ( Glis glis Linnaeus, 1758) from the western Balkans in Sl...
This study presents the results of an ornitho-archaeological analysis of avian bones from Stare gmajne and Blatna Brezovica, two Eneolithic pile dwelling sites in the area of Ljubljansko barje, Slovenia. Avian bone remains, together with remnants of huts, tools, mammal bones and bones of other vertebrates, represent the material remnant of a pile d...
In this study we address the taxonomic identity of Hypudaeus syriacus , an arvicoline (Arvicolinae) from the Middle East which was described and named by Anton Brants in 1827. Although the type specimen is preserved, an exact conclusion regarding its identity was not achieved until recently. Currently, syriacus is reported as a synonym of Microtus...
In this work, we investigated the relationship between habitat types (HTs) and selected environmental factors in the highlands at altitudes of 1800–2558 m in the Kamnik-Savinja (KS) Alps in Slovenia. For 275 sampling sites, we identified seven HTs in their typical form and 11 ecotones, and provided field and modelled data for 14 environmental facto...
Protura is a small class of Hexapoda, generally poorly known, and rather scarce data on
its occurrence in caves are scattered throughout literature on fauna in caves and in some
papers on Protura. Although the cave-dwelling fauna is relatively well studied in Slovenia,
published records on Protura are rare. In this paper, data on the occurrence and...
We address in this study the taxonomic status of the two major phylogenetic lineages of fat dormice, genus Glis . These lineages show unique mutations at 43 positions of the cytochrome b alignment and are classified as two distinct species, the European fat dormouse Glis glis (Linnaeus, C. [1766]. Systema naturae per regna tria naturae, secundum cl...
Multi-proxy analysis of the coprolites which were found during excavations at two Late Neolithic (fourth millennium bc) pile-dwelling sites (Črnelnik and Stare gmajne) in Slovenia yielded some new insights into human-dog relations and behaviour. The digested content is presented in a multidisciplinary approach, in which palynological, palaeoparasit...
Over the last decades, the European Hamster (Cricetus cricetus) has been declining in many parts of its European range. Due to the lack of recent information on the occurrence and status of the European Hamster in the south-western Carpathian Basin west of the Danube, we used information gathered from prey remains in Common Barn-owl (Tyto alba) pel...
We explore the pattern of spatial variation in mandibular morphology in relation to subspecific taxonomy in the dwarf fat-tailed jerboa, Pygeretmus pumilio. The unguided k-means clustering on mandible shape scores, partitioned populations into two clusters, corresponding to western and eastern populations. These clusters nearly perfectly matched th...

Following the classical MacArthur‐Wilson island equilibrium model of species richness, we hypothesize that island size and isolation affect prey composition and diet diversity of predators on islands. We used the barn owl as a model predatory organism that is known for feeding and habitat flexibility and explored the patterns of its diet on Med...
Arid areas have a comparatively narrow range of habitat types, with restricted variation in environmental parameters, leaving narrow boundaries for phenotypic variation to correlate with ecological variables. To test this presumption, we explored variation in size and shape of the mandible in the dwarf fat-tailed jerboa (Pygeretmus pumilio (Kerr, 1...
The European cave spider, Meta menardi, is a representative of the troglophiles, i.e. non-strictly subterranean organisms. Our aim was to interpret the cytological results from an ecological perspective, and provide a synthesis of the hitherto knowledge about M. menardi into a theory of key features marking it a troglophile. We studied ultrastructu...
Over centuries, in many European countries, the white mulberry trees ( Morus alba L.) became an integral part of the cultural landscape, bearing witness to past sericulture activities. The distribution records of white mulberry trees in the cultural landscape are incomplete and in general poorly documented. The aim of the presented research was to...
The article presents dietary habits of the Peregrine Falcon in the urban environment of Maribor. The diet was studied with an analysis of prey remnants at the nesting site. In October 2015, prey remnants were collected after the nesting in and around the nest built on top of the grain storage silo. Prey remnants, mostly bones and feathers, were sor...
The European cave spider, Meta menardi, is among the most common troglophile species inhabiting the cave entrance zone in Europe, where prey is scarce in winter. Spiders feed only if prey is available; otherwise, they are subjected to long-term winter starvation. We carried out a four-month winter starvation of M. menardi under controlled condition...
The Pannonian Plain is large sedimentary lowlands in Central/south-eastern Europe. Two protected sand dune areas in the southern rim of the Pannonian Plain were surveyed for the presence of Neuroptera. Đurđevac sands in Croatia is a special geographical and botanical reserve, occupying only about 0.2 km², whereas Special Nature Reserve Deliblato sa...
During the course of three Balkan neuropterological expeditions in 2014, 2015 and 2017, short visits to three national parks were conducted. A survey of the collected neuropterid species (Neuropterida: Raphidioptera, Neuroptera) in the Fir of Drenova National Park, Albania, the Tara National Park, Serbia, and the Pelister National Park, North Maced...
During the growth period, in surface habitats, spiders catch enough prey to feed normally. In contrast, in the cave entrance zone, prey may be relatively scarce. Meta menardi inhabits this cave section, resulting in temporary starvation. We studied structural changes in the midgut epithelial cells of M. menardi during a short-term and a medium-term...
An inventory of butterfly fauna was carried out in 2017 within the north-western part of the Prime Butterfly Area “Avala Mt.”. Butterfly fauna was surveyed with a transect method from March until October within three sectors with different land use and plant succession. We evaluated the sectors by butterfly species richness, abundance of individual...

The ultrastructure of their fat body (FB) cells and Malpighian tubule (MT) epithelial cells was studied by light microscopy and transmission electron microscopy, and essential biometric and biochemical measurements were performed. The FB was composed of adipocytes and sparse...
The striped ground squirrel has a wide distribution in the Ethiopian region but is restricted to a small isolated area in Palaearctic Africa. This fragment was first recorded in the late 1940s in the Souss Valley (Morocco), however, not a single new observation has been published in the following decades. In September 2016 we surveyed the Souss Val...
We studied interspecific variability in external, cranial, and dental traits in seven species belonging to
two closely related arvicoline (Arvicolinae) subgenera, the social voles (Sumeriomys) and the grey voles
(Microtus). These voles were for long regarded as morphologically cryptic and the species complexity was
fully appreciated only after chro...
The skull of the grey heron (Ardea cinerea) was examined with an emphasis on describing the orbital region. In the young (circa sixteen to seventeen days old) heron, the frontal bone (os frontale) and nasal bone (os nasale) comprised separate paired bones, connected by sutures (sutura interfrontalis, sutura internasalis and sutura frontonasalis pla...
We have analysed the structure of cultivable choanal microbiota from free-living birds in relation to bird diet, its richness and the relative number of opportunistic bacteria acquired from the environment. For this purpose, we have taken choanal swabs from 25 free-living birds representing 13 different bird species captured in Slovenia. From the g...
In nature conservation, providing new, advanced knowledge of protected habitats and biota often requires extensive sampling, which contradicts the main goal of minimizing damage and disturbance. How to avoid this innate collision was the main concern in our study. Highland habitats are suitable for addressing this problem, since they are relatively...
Data on the occurrence of four spongillafly species in the Balkan countries are provided. Two species are recorded for the first time in two countries: Sisyra nigra (Retzius, 1783) in Serbia and Bosnia and Herzegovina and Sisyra terminalis Curtis, 1854 in Serbia.
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...
We addressed the effects of phylogeny, ecology, and allometry on shape variation in ventral cranium,
mandible and maxillary tooth-row in all five extant bandicoot rats. These rats are classified
into two genera (Bandicota and Nesokia) and occupy different ecological niches along fossorial to
aquatic gradient. The analysed structures are controlled...
We present a simple, manageable and cheap method for accelerated disturbance and, consequently, detection of thanatotic and soil-mimetic arachnids and other arthropods. The method combines sieving a substrate in the field, followed by heating and lighting the dispersed sample by a handheld electric light in the laboratory. The name Hot-Dancing allu...
Na štirih skeletih sive čaplje (Ardea cinerea) smo proučili morfološke lastnosti kosti in skeletnih sklopov, predvsem nekatere segmente lobanje, hrbtenice, plečnega obroča, prsnice in medeničnega obroča. Za lobanjo je značilna izrazita kra-niofacialna upogibna cona (zona flexoria craniofacialis), dolga čelnica (os frontale) z izrazito vzdolžno depr...
During winter, cave cricket larvae undergo dormancy in subterranean habitats; this dormancy is termed diapause in second year Troglophilus cavicola larvae because they mature during this time, and termed quiescence in T. neglectus, because they mature after dormancy. Here we used electron microscopy to analyze ultrastructural changes in the epithel...

We studied 468 museum specimens of the common hamster (387 skins and 204 skulls) collected in Belarus, Ukraine, Russia and Kazakhstan. Besides a standard tricolour type which prevailed, we identified six colour variants: stavropolicus with reduced white spots, and a bicolour entirely devoid of spots, white, piebald, dark-black (atypical melanistic)...
The work presents anatomical terminology of bones of a bird skeleton. An individual technical term is written in the international standard form, i.e. in Latin or Latinized Greek, mostly followed by the slovenized technical term and afterwards by the Slovenian expression for the individual anatomical term. The succession of terms follows the anatom...
Fragmented landscapes entail important consequences for the evolution of the species confined to them. Isolation of population fragments accelerates selection for narrow local conditions and facilitates morphological divergence. Throughout its range, the European snow vole Chionomys nivalis is restricted to fractured, rocky substrate in mountain re...

Pellets were collected from 16 localities across the Posavina region in the winter season of 2012/13. A total of 442 prey items and 11 prey taxa were identified. Small mammals accounted for 94% and birds 6%. Voles,...
The peregrine earthworm Dendrodrilus rubidus tenuis was regularly sampled in a percolating water drip originating in a habitat inaccessible to humans in the Huda luknja pri Dolicu cave, Slovenia. The reconstruction of this habitat includes both a larger passage with bat colonies supplying wet bat guano sediments, on which the earthworms feed, and n...
The harvestmen Amilenus aurantiacus overwinter in diapause in hypogean habitats. The midgut diverticula have been studied microscopically (light microscopy, TEM) and biochemically (energy-storing compounds: lipids and glycogen) to analyze changes during this programmed starvation period. Throughout the investigated period, the epithelium of the mid...
Most organisms are able to survive shorter or longer exposure to sub-zero temperatures. Hypothetically, trogloxenes characterized as not adapted, and troglophiles as not completely adapted to thermally stable subterranean environment, have retained or partially retained their ability to withstand freezing, while most troglobionts have not. We teste...
Juvenile harvestmen Gyas annulatus overwinter in dormancy in hypogean habitats for 4-5 months. The ultrastructure of the autophagic structures in their midgut epithelium cells was studied by light-, transmission electron microscopy (TEM) and immunofluorescence microscopy (IFM) during this non-feeding period. Before overwintering (November), autopha...
Eleven of the most important terrestrial invertebrate species in Slovenian caves were analyzed for differences in their fresh and dry biomass, energy content and carbon bulk during winter. These data were combined with the species abundance in 54 caves and adits in order to estimate their organic carbon bulk and carbon input into these habitats. In...
For the understanding of shrew communities, their coexistence and competition, the knowledge of diet partitioning among sympatric shrew species is crucial. In this study, the trophic niches of three coexisting Sorex species: S. alpinus, S. araneus and S. minutus were compared for the first time. Shrews were taken from a montane forest habitat in no...

In this work we have compared the ultrastructural characteristics of major pancreatic endocrine cells, pituitary melanotrophs and adrenal chromaffin cells in the normal mouse strain (wild type, WT) and mice with a known secretory deficit, the Rab3a knockout strain (Rab3a KO). For this purpose, pancreata, pituitary glands and adrenal glands from the...
Until recently in Slovenia, the presence of invertebrates in the shrew diet had not been investigated. Here we present a list of invertebrates and other ingested items in five shrew species: Sorex alpinus, S. araneus, S. minutus, Crocidura suaveolens and Neomys fodiens in Slovenia. These shrews fed mostly on arthropods and earthworms. Among the art...
Sand-dwelling antlion larvae are well known predators with a highly specialized prey-catching strategy, which either construct efficient pitfall traps or bury themselves in the sand ambushing prey on the surface. Although habitat selection in antlions has been extensively studied, little is known about the role substrate density plays in such behav...
Terrestrial animals in subterranean habitats are often classified according to their degree of morphological or ecological specialization to the subterranean environment. The commonly held view is that, as distance into a cave increases, the frequency of morphologically specialized, i.e., troglomorphic, species or ecological specialization will inc...

and habitat of the species are provided.
The cave crickets Troglophilus cavicola and Troglophilus neglectus are the most widely distributed European species of the family Rhaphidophoridae. Their life cycles span two years. They overwinter twice in caves in 4-6 months lasting diapause, T. cavicola in warmer microhabitats. In caves, older T. cavicola undergo sexual maturation, while T. negl...
Active student-centered instructional methods bring more emotion into science teaching, especially in the case of socioscientific issues, like research on and usage of genetically modified organisms (GMOs). We tested the strength of ten basic emotions (fear, anger, joy, disgust, sadness, shame, contempt, guilt, surprise and interest) toward differe...
Three hymenopteran species – the ichneumonids Amblyteles armatorius and Diphyus quadripunctorius, and the proctotrupid Exallonyx longicornis – are most frequently cited from all over Europe as executing their inactive hypogean ecophase in caves. Yet, little is known about their environmental requirements during their summer quiescence and/or winter...
Hypogean habitats are relatively simple exhibiting low diversity, low production and relative constancy of environmental factors, and are therefore appropriate for studying species coexistence in situ. We investigated the coexistence of two closely related, similarly sized orb-weaving spider species, Meta menardi and Metellina merianae, living synt...
Small mammals were sampled on Mt. Pohorje at 33 localities, ranging in elevation from 250-300 m to 1530 m a.s.l. Species composition varied, depending on the method employed during field surveys. Snap trapping was more effective in sampling rodents while pitfall trapping provided more shrews. Twenty-two species were identified, but commensal Rattus...
Phalangium opilio is the most widespread and one of the most common harvestman species in anthropogenic environments. A preliminary field experiment was carried out in Slovenia testing its preferences for different substrates. A two metres high rectangular tower with walls constituted of vertical bands of concrete, twice fired tile, wood and styrof...
The fauna and community ecology of percolation water was studied using monthly samples of 12 drips in the Medvedji rov in the cave Huda luknja. This is the largest cave system in the so-called isolated karst which consists of limestone patches of <1 to 10 km2 in size in central and northeastern Slovenia. Huda luknja is developed in one of these pat...
Elevational pattern in reptilian species richness and species turnover was studied on two Dinaric mountains along the eastern Adriatic coast: northern Mt. Velebit and Mt. Biokovo. Both mountains had similar numbers of species (20 and 22, respectively) and showed a gradual decline in species richness with increasing elevation. Lizard species richnes...
We studied leaf fluctuating asymmetry in Myrtus communis occurring around the "I Borboi" natural CO2 spring (Tuscany, Italy) and in a nearby control site, in a Mediterranean environment. Developmental instability, measured as leaf fluctuating asymmetry, is expected to be positively related to environmental stress and negatively to habitat quality....
We sampled 54 caves and galleries in north and east Slovenia methodically for ecological data and the invertebrate fauna. The snow fly Chionea austriaca, recorded in 37% of the cavities, proved indifferent with regard to most of the abiotic factors, but occurred in significantly higher individual numbers in caves on north and east slopes. The subte...
Among the trogulid harvestman Trogulus nepaeformis (Scopoli 1763) collected from sixty localities in Slovenia and northeastern Italy we found many individuals with evidence of old leg injuries. In a few localities, injured individuals accounted for 30% of the total. In non-autotomizing trogulids, in vivo damage to leg articles is characterized by r...
We studied phenotypic relationships among 13 samples of two rock mice species:Apodemus mystacinus (Danford and Alston, 1877) from Anatolia (n = 38) andA. epimelas (Nehring, 1902) from the Balkans (n = 71). Cartesian coordinates of landmarks were collected on the skull and on the occlusal projection of the upper molars
(18 landmarks). Centroid size...
The larvae of the antlion Euroleon nostras are pit-builders, constructing pitfall traps in loose sand. The number of pits and the pit diameter are recorded when larvae are kept in substrates with different particle sizes. The most convenient pit-building sand fractions are two fractions with fine sand (≤ 0.23 mm; 0.23–0.54 mm). The largest pits are...
The Christmas rose (Helleborus niger L.) is widely distributed in Southern and Central Europe, and Slovenia is probably one of the centers of its diversity.
