During the regular biospeleological monitoring in Veternica cave (Mt. Medvednica, Croatia), particular synnematous entomogenous fungus parasitizing on an imago of subtroglophilic fly Heteromyza sp. have been found. Specimens found dark zone were sampled, microclimate data recorded and photo documentation performed. The was identified as Polycephalomyces ramosus. Detailed description, based living material, supplemented with drawings photographs is given. Microscopic study includes...

The Dinaric Karst is a global hotspot for subterranean diversity, with two distinct peaks of species richness in the northwest and southeast, an area lower central part. In this article, we present list describe ecological conditions Lukina jama–Trojama cave system, located part Karst. This system deepest one most logistically challenging systems sampled so far Repeated sampling resulted 45 species, including 25 troglobionts, 3 troglophiles, 16 stygobionts, 1 stygophile. Most recorded are...

Dinaric limestone cave systems, recognized as a hotspot of subterranean biodiversity, inhabit composite microbial communities whose structure, function and importance to ecosystems was poorly considered until the last few years. Filamentous biofilms from three caves in karst were assessed using 16S rRNA-based phylogenetic approach combined with universally protein coding genes/proteins. Studied clone libraries shared divisions but distribution obtained phylotypes differed: Veternica...

The first record of the palpigrade Eukoenenia gasparoi Condé 1988 in Croatia is reported. We review distribution this troglobiotic species endemic to classical European Karst region, give an illustrated description adult stages and juvenile female, evaluate divergence among populations. Morphological differences reflect individual-level rather than population-level variation.

The Western Balkan’s Vjetrenica Cave in southern Bosnia and Herzegovina is renowned for high richness of subterranean species. However, the data on its fauna have been published only monographs printed a small number copies, making them hardly accessible to wider scientific community. To overcome this issue, we compiled from with our own recent field surveys. Further, as they are connected via water channels or crevices bedrock, defined System system comprising Bjelušica Caves Lukavac...

Crveno jezero (Red Lake) is one of the largest karstic sinkhole lakes in Europe. Diatom flora this lake was unknown due to difficulties collecting samples. Recently, samples were collected by speleodivers frame systematical natural sciences research, during cave diving expedition “Crveno 2017” and observations revealed existence a new species, Gomphosphenia plenkoviciae Gligora Udovič & Žutinić sp. nov. The species described herein as science based on light scanning electron microscopy....

Microphototrophs (algae and cyanobacteria) in karst environments have been intensively studied aquatic epigean habitats. In recent decades knowledge about the communities inhabiting cave entrances lampenflora has grown substantially, but data aphotic zone are scarce. This study aimed to investigate spatio-temporal presence of microphototrophs Veternica Cave (Mt. Medvednica karst) present additional preliminary from 22 caves Dinaric karst. The were collected over ten years, parallel with...

The adult male of Euscorpius feti Tropea, 2013 (Euscorpiidae) is described for the first time. A large series (45 specimens including type material) has been studied, most material previously unpublished. E. found in as many 17 caves Croatia and Bosnia-Herzegovina, Adriatic islands, which makes it common species so far caves. Ecological notes on this are presented.

Testate amoebae are phylogenetically a very diverse group of eukaryotic microorganisms. They can be found in marine and freshwater habitats soil. Some these single-celled organisms inhabit both surface cave habitats, but their diversity caves has barely been explored. Recent studies the Dinaric region imply that testate show high diversity. The aim this study was to identify alpha Lika (Dinaric karst, Croatia) compare different based on assemblages. In eight we more than 40 taxa, including...
