2. Affinity of four different extraction chromatographic resin for Pd and Ag : toward efficient separation of Pd from AgLeja Rovan Stiplošek, Mariella Van Ginkel, Michele Toma, Marko Štrok, 2026, izvirni znanstveni članek Povzetek: In this study, the affinity of four extraction chromatographic resins from TrisKem International (TK200 Resin, Ni Resin, LN Resin, and TBP Resin) for retaining Pd and Ag in nitric and hydrochloric acid medium of various molarities was systematically investigated. Batch experiments were performed in which the resins were contacted with Pd and Ag solutions prepared in nitric and hydrochloric acids of different molarities. Affinity of specific resin for Pd and Ag was assessed with the help of distribution coefficients (Kd), defined as the ratio of the concentration of a specific element between resin and solution under equilibrium conditions, as a function of nitric and hydrochloric acid concentration. The results provided fundamental insight into behaviour of Pd and Ag in connection with different resin under varying chemical conditions and enabled design of optimum Pd and Ag column separation protocol. Among the resins investigated, Ni Resin and TK200 Resin exhibited the most favourable selectivity and separation performance, allowing efficient and reproducible Pd–Ag separation with high recoveries. For Ni Resin, the overall recovery was 92% for Pd and 98% for Ag, with a Pd separation factor of 2500±300. For TK200 Resin, the overall recovery was 89% for Pd and 98% for Ag, with a Pd separation factor of 770±80. However, an additional separation step would be required to achieve a higher separation factor when using TK200 Resin.

3. Uncovering two freshwater brown algae Bodanella lauterborni and Heribaudiella fluviatilis in Serbia (Southeast Europe)Aleksandra B. Rakonjac, Tijana Veličković, Kristina A. Markeljić, Nevena B. Đorđević, Snežana B. Simić, 2026, izvirni znanstveni članek Povzetek: Bodanella lauterborni W.M. Zimmermann and Heribaudiella fluviatilis (Areschoug) Svedelius are members of brown algae (Phaeophyceae) that exclusively inhabit freshwater habitats. Heribaudiella fluviatilis is the most frequently reported freshwater brown alga, widely distributed in the Northern Hemisphere. In contrast, B. lauterborni, one of the rarest algae globally, has been reported in only four glacial Alpine lakes and has not been observed in nature for nearly 50 years. Since 2019, the species has been considered locally extinct at its type locality, and its presence in the other three lakes is also questionable. Here, we report the occurrence of B. lauterborni in three springs on the Vlasina Plateau (Southeast Serbia), being the first finding of the species in Southeast Europe and the fifth discovery globally in environmental conditions not previously described for the species. We also provide detailed data on the morphology, ecology, and biogeography of B. lauterborni and H. fluviatilis. Additionally, we report the non-obligate association Hildenbrandio rivularis-Heribaudielletum fluviatilis discovered in two rivers. Our findings significantly expand the known ecological and geographical range of phaeophytes, highlighting Southeast Europe as a refugium for freshwater Phaeophyceae biodiversity.

4. Introduced or established? Convergent evidence indicates imported pine wood nematode vectors occupy gaps in native distributionJean-Claude Grégoire, Jean Artois, Julien Claude, Marius Gilbert, Serge Morand, Géraldine Roux, Gilles San Martin, Dimitrios N. Avtzis, Nick Berkvens, Jochem Bonte, Tine Hauptman, 2026, izvirni znanstveni članek Povzetek: Monitoring regulated quarantine plant pathogens and, when relevant, their vectors is compulsory in the European Union. Local Monochamus species (Coleoptera, Cerambycidae) vector the pine wood nematode, Bursaphelenchus xylophilus, a non-native pest already established in most of Portugal. Only 29 M. galloprovincialis individuals were trapped in Belgium in ten years (2013–2022), despite a dense coverage of pheromone-baited traps, suggesting absence or a very rare local occurrence in the country. In the northern neighbouring countries, only one single established population is known in The Netherlands and one in Denmark. A species distribution model based on pheromone-trap catches (negative and positive) of M. galloprovincialis from 4,914 traps in 29 European countries between 2008 and 2019 was developed, using the overall climate conditions and the distribution of seven pine tree species as explanatory variables. The effect of spatial scale was tested with a multi-scale approach. With a 225*225 km spatial grain, the major explanatory variables were the mean diurnal temperature range and, to a lesser extent, the presence of Pinus spp. The model predicted a low probability of presence in Belgium, the Netherlands, Great Britain and north-western Germany compared to southern Europe. Genotyping allowed to conclude that at least some of the beetles caught in Belgium originated from foreign locations. All catches were located close to entry points, suggesting introduction with imported material. The small size of most of the Belgian pine stands may also explain the absence or apparently transient status, or rareness of Monochamus spp. This study thus suggests that surveys in Belgium should privilege entry points rather than local forest stands.

5. Native trees of the Mediterranean region : distribution, diversity and conservation challengesBruno Fady, Anna-Maria Farsakoglou, Maria Mercedes Caron, Khaled Abulaila, Jelena M. Aleksic, Sajad Alipour, Dalibor Ballian, Heba Bedair, Faruk Bogunić, Marwan Cheikh Albassatneh, 2025, izvirni znanstveni članek Povzetek: Purpose of Review While 38% of tree species are at risk of extinction worldwide, their inventory and occurrence at ecologically and biogeographically meaningful scales is lacking in many parts of the world, including the biodiversity-rich Mediterranean region. Here, we provide presence/absence, extinction risk, biogeography and genetic diversity data of trees in 39 climatically and ecologically Mediterranean territories (so-called “botanical territories”) in North Africa, Western Asia and Southern Europe. Recent Findings The inventory includes 496 species and 147 subspecies from 50 families and 111 genera, including 48 species and 8 subspecies previously not considered as trees. We show that native tree species distribution is highly skewed across the tree of life with a few species-rich families such as the Rosaceae and the majority with less than 1% of all species. Endemism was not evenly distributed among botanical territories and neither was extinction risk, an assessment of which was lacking in almost half of the species. While no geographic trends were detectable, species richness was found to be positively correlated with botanical territory area and, when standardized by area, with habitat heterogeneity. Information on genetic diversity was lacking in two thirds of the species inventoried and mostly focused on species with economic importance. Summary Our data are open access and can be used by researchers and stakeholders for a wide range of purposes, including conservation and restoration. Our findings identified major native tree richness hotspots as well as key knowledge gaps and biases related to extinction risk and genetic diversity. Our findings also emphasize the importance of increased collaboration to support the conservation of Mediterranean forest trees.

8. History and biology of the "black proteus" (Proteus anguinus parkelj Sket & Arntzen 1994; Amphibia: Proteidae): a reviewLilijana Bizjak-Mali, Boris Sket, 2019, pregledni znanstveni članek Povzetek: Proteus anguinus parkelj Sket & Arntzen 1994 is a black pigmented with developed eyes, non-troglomorphic, but yet troglobiotic subspecies of P. anguinus Laurenti 1786. It is endemic to the karst of Bela krajina in southeast Slovenia. As a probable mimic of the epigean ancestor it is very informative regarding adaptation to subterranean environment. Since it was discovered only in 1986, relatively little is known about its biology. The purpose of this review paper is to summarize the published data about the circumstances of its discovery, its distribution, phylogeny, taxonomy and its biology, including environmental threats, conservation status, and actions that are being taken to ensure its survival. The exceedingly limited distribution of the black proteus makes it particularly vulnerable. It is endangered by environmental pollution as well as by various potential pathogens that are of global concern to amphibians. Populations of the black proteus are in dire need of protection if they are to survive in their own natural habitat.

9. Diversity, distribution and cultural significance of Coccinellidae (Ladybirds) in the Dehradun region of Uttarakhand, IndiaShafkat Jabbar Mir, Musheerul Hassan, Muhammad Shoaib Amjad, Ivana Vitasović Kosić, Mohd Majid Jamali, Rainer W. Bussmann, 2025, ni določena Povzetek: This study assesses the diversity, distribution, and cultural significance of Coccinellidae (ladybirds) in Dehradun (India), documenting 32 species from 19 genera, with Coccinella as the predominant genus, including C. septempunctata, C. transversalis and Cheilomenes sexmaculata. Species richness was greatest at lower altitudes (300 m), with Coccinella septempunctata and Hippodamia variegatashowing a wide altitudinal distribution and a marked decrease with increasing altitude. Agricultural ecosystems harboured the greatest diversity of Coccinellidae, due to the availability of prey and habitat heterogeneity, while flower gardens, mango orchards and forests harboured fewer species. In particular, Illeis cincta, Halyzia sanscrita and Harmonia axyridis were frequently observed in both agricultural and floral habitats, reflecting their ecological adaptability. We studied also ethnozoological practices of Vann Gujjar and Pahari communities, who use species such as Coccinella hieroglyphica, C. leonina and Propylea dissecta to treat ailments such as asthma, cough and skin diseases. A cross-cultural analysis revealed different preferences between the species, with Coccinella septempunctata having the highest cultural value due to its symbolic and medicinal significance

10. First record of Cistus salviifolius L. (Cistaceae) for the flora of North MacedoniaSlavčo Hristovski, Renata Ćušterevska, Vlado Matevski, 2025, ni določena Povzetek: The watershed of river Crn Drim in south-western parts of North Macedonia (Galičica and Jablanica mountains with the Ohrid valley in between) are under the influence of transitional mild continental to modified (sub)Mediterranean climate. These conditions support the development of rich flora and vegetation with presence of many relict and endemic species. Such is Cistus salviifolius L. (Sageleaf Rockrose) of the family Cistaceae, a species with Circum–Mediterranean distribution. This paper presents the first record of this species in North Macedonia, in the vicinity of Ohrid town (Trojani area), about 60km away from its nearest locality in Albania. The flora and vegetation associated with Cistus salviifolius in Trojani area are significantly different from the studied ones in which this species thrives in Northern Greece. Most of the recorded individuals develop on eroded regosols on silicate bedrock (phyllitic schists). Considering the small extent of occurrence in North Macedonia (62 ha), the threat status of Cistus salviifolius was assessed as Endangered [EN B1a+2a]. Future biogeographical studies supported by molecular analysis can explore distribution pathways, as well as past and present ecological conditions in the watershed of river Crn Drim.
