Sažetak
The cave Špilja na Gradini kod Premanture is the southernmost cave on the Istrian peninsula, Croatia, located in the Upper Kamenjak significant landscape. It is a part of the Natura 2000 network of protected areas, protected under the Habitats Directive of the European Union as a habitat type classified as “caves not open to the public.” The cave is of simple morphology, consisting of one canal which is 102 m long and 22 m deep. It is a type and, as far it is known, the only locality for a troglophilic isopod subspecies Androniscus roseus histrianorum. The first systematic biospeleological study that included microclimate measurements (air and soil temperature, and relative humidity) of Špilja na Gradini kod Premanture was conducted in 2016. Then 27 taxa of invertebrates were documented, including four troglobionts and ten troglophiles. The cave was divided into three parts, covering different habitats and fauna structures, and a monitoring proposal was given. Biospeleological monitoring started in 2021 when troglophilic spider Metellina merianae was recorded for the first time in the locality, raising the total number of invertebrate taxa to 28. Microclimatic conditions in the cave remained unchanged compared to 2016 measurements. Although most taxa in the cave are troglophilic, the most numerous taxon recorded in 2021 was troglobiontic isopod Alpioniscus strasseri. A decline of both, Collembola and the endemic A. roseus histrianorum populations, was documented in 2021. Further monitoring of the habitat and the species populations is essential and will be continued in collaboration with the Kamenjak Public Institution.
