Utilising public sequence databases to investigate genetic diversity of stoneflies in Medvednica Nature Park.

In Medvednica Nature Park, near Croatia's capital Zagreb, urbanisation significantly impacts the fauna. Comprehensive field research has never been conducted in this area, despite the presence of diverse microhabitats and the discovery of several rare species previously unknown in the Croatian fauna. This study provides the Park with first insight into the genetic and morphological diversity of stoneflies, one of the most endangered groups of organisms.

Molecular analyses of pseudoscorpions in a subterranean biodiversity hotspot reveal cryptic diversity and microendemism.

Nested within the Mediterranean biodiversity hotspot, the Dinaric Karst of the western Balkans is one of the world's most heterogeneous subterranean ecosystems and renowned for its highly diverse and mostly endemic fauna. The evolutionary processes leading to both endemism and diversity remain insufficiently understood, and large-scale analyses on taxa that are abundant in both subterranean and surface habitats remain infrequent. Here, we provide the first comprehensive molecular study on Croatian pseudoscorpions, a lineage of arachnids that is common and diverse in both habitats.

DNA barcoding for biodiversity assessment: Croatian stoneflies (Insecta: Plecoptera).

Background: The hemi-metabolous aquatic order Plecoptera (stoneflies) constitutes an indispensable part of terrestrial and aquatic food webs due to their specific life cycle and habitat requirements. Stoneflies are considered one of the most sensitive groups to environmental changes in freshwater ecosystems and anthropogenic changes have caused range contraction of many species. Given the critical threat to stoneflies, the study of their distribution, morphological variability and genetic diversity should be one of the priorities in conservation biology.

Potamophylax idliri sp. nov. (Trichoptera: Limnephilidae), a new species from the Jastrebac Mountains in Serbia, with molecular and ecological notes.

In this paper, we describe a new species, Potamophylax idliri sp. nov., from the Jastrebac Mountains in Serbia, which is morphologically most similar to Potamophylax coronavirus Ibrahimi, Bilalli Vitecek 2021 (in Ibrahimi et al.

Morphological and molecular characterisation of the Popijač's Yellow Sally, sp. nov., a new stenoendemic stonefly species from Croatia (Plecoptera, Perlodidae).

A new species of the Yellow Sally genus ( Banks, 1906) is described, based on morphological (males and females adults, larval and egg) and molecular (the barcode region of the cytochrome c oxidase subunit I gene ()) features. Popijač's Yellow Sally, Hlebec & Sivec, inhabits two karstic sources of the Krasulja rivulet in Croatia. Male and female of the new species are characterised by colouration patterns of the head and pronotum; the dimensions of the female subgenital plate; the medial penial armature and oval-shaped egg without collar and anchor.

Mineral Composition of Elements in Walnuts and Walnut Oils.

Walnuts () are considered to be a functional food. In the present study, twenty one macro-, micro-, and trace elements (Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Se, Sr, and Zn) were selected to be determined in walnuts and walnut oils. The beneficial content of essential elements could be shown by the obtained results, the macro-elements Ca, K, Mg, and Na being present in nuts with 1062 mg/kg, 2771 mg/kg, 1426 mg/kg, and 42.
