1. New records of marine biodiversity in the Mediterranean Sea (April 2026)Argyro Zenetos, Fares Nasser Abd El-Gwaad, Ahmed Mohamed Al-Beak, Neža Leban, Domen Trkov, 2026, izvirni znanstveni članek Povzetek: This collective article presents new information about 18 species occurring in 12 Mediterranean countries from the Alboran Sea to the Levantine Sea. Five lessepsian species namely Erugosquilla massavensis, Syrnola fasciata, Plocamopherus ocellatus, Maritigrella fuscopunctata and Siganus javus have spread within 2025 to neighbouring MSFD areas. Another five are here reported as first country records [Polyandrocarpa zorritensis (Malta), Gonioinfradens giardi (Italy), Istiblennius meleagris (Egypt), Epinephelus fasciatus (Israel), Lophocladia trichoclados (Montenegro)]. Cladophora patentiramea has spread from the Levantine to the Aegean Sea, while Pinctada radiata has reached Granada, and Cádiz. The Atlantic fish Enchelycore anatina and Synodus synodus have expanded their distribution to Montenegro and Syria respectively. Three rare native species are reported for first time at country level, while a fourth (Mobula birostris) has made an appearance more than a century after its first Mediterranean record.

2. Data from: A comprehensive occurrence dataset for European Ostracoda inhabiting groundwater and groundwater-dependent ecosystemsNataša Mori, Živa Vehovar, Traian Brad, Gergely Balázs, Constanze Englisch, Cene Fišer, Santiago Gaviria, Sanja Gottstein, Christian Griebler, Marius Kenesz, Lee R. F. D. Knight, Pierre Marmonier, Florian Malard, Stefano Mammola, Alejandro Martinez Garcia, Maja Zagmajster, 2025, zaključena znanstvena zbirka raziskovalnih podatkov Povzetek: Motivation Groundwater ecosystems sustain a unique and globally important biodiversity but remain understudied due to sampling and exploration challenges, as well as a shortage of taxonomic experts. Groundwater ostracods, like other groundwater taxa, exhibit a high degree of endemism, rarity, and subterranean specialisation, positioning them as potentially vulnerable organisms. To better understand biodiversity patterns and the conservation needs of this highly diverse group, we assembled a team of experts to gather the most comprehensive information available about groundwater ostracods in Europe. We present a dataset comprising 2,065 occurrence records of 110 species, 11 undescribed species, and 5 subspecies of groundwater ostracods. This open dataset may support future research on the distribution, evolutionary pathways, and conservation needs of European groundwater ostracods, as well as inspire targeted sampling efforts in regions with currently limited data available. Main Types of Variables Contained Occurrence records of groundwater ostracods, with details about taxonomy, source of records, occurrence locality, habitat type, and species dependence on groundwater (obligate [stygobite] versus facultative groundwater-dwellers [stygophile]). Spatial Location and Grain Geographical Europe, spanning 32 countries. Occurrence records were assigned decimal degrees coordinates (EPSG:4326). Most occurrence records are at 100 m resolution. Time Period 1915–2024. Major Taxa and Level of Measurement Crustacea: Ostracoda. Most records have species or subspecies-level identification, while some are identified to genus or family levels. Software Format Comma-separated values file (.csv), with UTF-8 encoding and meta-data provided following the Darwin Core standard.

3. From loss to life: how empty Pinna nobilis shells enhance motile macroinvertebrate habitats in soft-bottom environmentsAna Fortič, Valentina Pitacco, Domen Trkov, 2026, izvirni znanstveni članek Povzetek: The noble pen shell (Pinna nobilis) is experiencing mass mortality events across the Mediterranean Sea. In the northern Adriatic, as in many other regions, soft-bottom habitats are now covered with numerous empty shells. To assess their ecological role, we conducted underwater SCUBA surveys using quadrats in 2023 and 2024. We examined the function of empty shells as refuges for motile epibenthic macroinvertebrates across vegetated and unvegetated habitats. Specifically, we compared invertebrate diversity among habitats with and without shells, assessed the influence of shell orientation on community composition, and identified taxa characteristic of each habitat type using non-invasive methods that did not displace shells. Most shells remained upright, though their density and orientation varied among the six study locations. We recorded fauna from seven classes, with malacostracans and gastropods being the most species-rich groups. Biodiversity metrics differed markedly among the four microhabitat types (sediment, sediment with shells, meadow, meadow with shells), reaching the highest values in meadows with shells and the lowest in bare sediment. Malacostracans and polyplacophorans were significantly more abundant in samples containing shells, while other taxa showed no consistent trends. Shell orientation did not affect the composition of motile fauna, but distinct assemblages were associated with specific habitat types. These findings highlight the ecological importance of P. nobilis shells as microhabitats that enhance coastal biodiversity even after the death of the organism and underline the potential negative consequences of their degradation or removal.

5. Nastanek endemične in epistemične vrste : primer premestitve aksolotlaCristian M. Torres Gutiérrez, 2025, izvirni znanstveni članek Povzetek: Aksolotl (Ambystoma Mexicanum), zanimiva vodna pošast, laboratorijski organizem, nacionalni simbol, ki krasi mehiške bankovce, je žival, ki nastopa v več medvrstnih prepletih. Odkar je bil v sredini 19. stoletja premeščen iz mehiške jezerske doline v evropske laboratorije, se je večina raziskovalcev osredotočala predvsem na beleženje preobrazbe te vrste v modelni organizem v znanstvenih raziskavah. Aksolotl uspeva kot modelni organizem v kontroliranih pogojih, medtem ko je v svojem naravnem okolju uvrščen med ogrožene vrste. V tem članku se zgodovine aksolotla lotim s pomočjo konjunkturalističnega pristopa, pri čemer se osredotočam na aksolotlov prehod iz njegovega endemičnega okolja (jezera) v epistemični prostor (laboratorij). Trdim, da je ta premik povzročil razdvojitev vednosti o aksolotlu, ki se je razvila v njegovem naravnem habitatu, od vednosti, proizvedene v umetnem okolju laboratorija. Prek prepletanja pripovedi in kontekstov, ki aksolotla obdajajo v različnih okoljih, članek poskuša spodbuditi dialog med avtohtonimi perspektivami in znanstvenimi praksami. Poleg tega bo pokazal, da habitate pomembno oblikujejo zunanji dejavniki, ki pogosto postanejo neprepoznavni po tem, ko žival vstopi v laboratorij. Obravnava teh zapletov bo razkrila, da je naše razumevanje neke vrste neločljivo povezano s kontekstom, v katerem se proučuje, in nakazala možnosti zbliževanja pripovedi iz različnih okolij.

6. 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

7. 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.

8. Climate-driven habitat shifts in brown algal forests: insights from the Adriatic SeaDaša Donša, Danijel Ivajnšič, Lovrenc Lipej, Domen Trkov, Borut Mavrič, Valentina Pitacco, Ana Fortič, Ana Lokovšek, Milijan Šiško, Martina Orlando-Bonaca, 2026, izvirni znanstveni članek Povzetek: Brown algal forests (Cystoseira sensu lato) are key habitat-forming components of temperate rocky coasts but have experienced widespread decline across the Mediterranean Sea. This study investigates the current distribution and potential future shifts in brown algal forests across the Adriatic Sea under ongoing climate change. We combined non-destructive field-based mapping along the Slovenian coastline with remote-sensing products and spatial environmental predictors to model basin-wide habitat suitability. A multiscale geographically weighted regression (MGWR) framework was applied to account for spatial non-stationarity and to explicitly capture the fact that environmental drivers of habitat suitability operate at different spatial scales—an assumption that global models such as GAM or standard GWR cannot adequately address. Habitat suitability maps were generated for present-day conditions and projected under mid- and late-century climate scenarios. The results reveal pronounced latitudinal gradients, identify areas of ongoing canopy decline in the northern Adriatic, and highlight parts of the southern Adriatic as potential climate refugia. Overall, the study demonstrates a likely north–south contraction of suitable habitat for brown algal forests and underscores the value of multiscale spatial modelling for informing marine spatial planning, conservation prioritization, and climate- adaptive restoration under European policy frameworks.
