Povzetek: In September 2024, a specimen of Maxmuelleria gigas (M. Müller, 1852) was found during a monitoring campaign in the Bay of Koper. This record is the second one of this less known macrobenthic species in the Slovenian Sea and one among few up to date reported in the Adriatic Sea, as well. Sediment mounds observed with an underwater video sledge on muddy bottom in the southern part of the Gulf of Trieste have been related to this species. The species distribution and density (47 per 100 m2) were estimated based on the quantification of the observed sediment mounds. The potential underestimation of the density and distribution of this species in the Gulf of Trieste in the past studies is discussed in relation to sampling method.

Povzetek: Trst je bil do prve svetovne vojne več kot petsto let del habsburške monarhije in pred njenim razpadom najpomembnejše pristanišče, ne nazadnje pa tudi mesto z daleč največjim številom Slovencev sploh. V njem si je slovensko meščanstvo leta 1904 postavilo svoje središče, Narodni dom, ki je v kratkem postalo osišče slovenskega družbenega življenja v mestu. Zaradi tega je bil v napoto italijanskim nacionalistom, ki so v njem videli »skrunitev« italijanskih tal, tako da so po prvi svetovni vojni, ko so mesto zasedle italijanske čete, dom napadli in ga zažgali, in sicer 13. julija 1920. Požig predstavlja enega prvih »uspehov« nastajajočega fašističnega gibanja in simbolni začetek naraščajoče protislovenske mržnje. Po sto letih se je začel formalni postopek vrnitve Narodnega doma slovenski narodni skupnosti v Trstu.

Povzetek: Freshwater ecosystems are full of underwater sounds produced by amphibians, aquatic arthropods, reptiles, plants, fishes, and methane bubbles escaping from the sediment. Although much headway has been made in recent years investigating the overall soundscapes of various freshwater ecosystems around the world, there remains a significant knowledge gap in our collective inability to accurately and reliably link recorded sounds with the species that produced them. Here, we present The Freshwater Sounds Archive, a new global initiative, which seeks to address this knowledge gap by collating species-specific freshwater sound recordings into a publicly available database. By means of metadata collection, we also present a snapshot of the species studied, the recording equipment, and recording parameters used by freshwater ecoacousticians globally. In total, 61 entries were submitted to the archive between the 4th of March 2023 and the 30th of April 2025, representing 16 countries and 6 continents. The most numerous taxonomic group was arthropods (29 entries), followed by fishes (14 entries), amphibians (10 entries), macrophytes (7 entries), and a freshwater mollusk (1 entry). The majority of the submissions were from European countries (27 entries), of which the United Kingdom was the most represented with 14 entries. The next most represented region was North America (11 entries), followed by South America (8 entries), Oceania and Asia (5 entries each), Africa (3 entries), and the Middle East and Central America with 1 entry each. The global south, polar regions, and areas with an elevation >500 m (asl) were underrepresented. The field of freshwater ecoacoustics to date has largely focused on the analysis of ‘sound types’ due to a current lack of knowledge of species-specific sounds. The Freshwater Sounds Archive presents an opportunity to move beyond the ‘sound type’ approach, and towards an approach with higher taxonomic resolution, ultimately resulting in species-specific descriptions. Furthermore, The Freshwater Sounds Archive will provide freshwater ecoacousticians with one of the main tools required to start creating annotated training datasets for machine learning models from soundscape recordings by referring to known species sounds present in the archive. In the long-term, this will result in the automatic detection and classification of species-specific freshwater sounds from soundscape recordings, such as indicator, invasive, and endangered species.

Povzetek: Beneath the Earth’s surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Though largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well-being. Subterranean ecosystems are integral to major biogeochemical cycles, sustain diverse surface habitats, and serve as the primary source of irrigation and drinking water. They also offer non-material benefits, including scientific discovery, education, and cultural practices. Yet, these contributions often go unrecognized, partly due to the lack of a unified synthesis of ecosystem services across terrestrial, freshwater, and marine subterranean compartments. This gap limits effective communication of their value to scientists, practitioners, and the public. Through a systematic expert-based review, we show that subterranean ecosystems contribute to up to 75% of classified ecosystem services. Notably, many of these contributions are described only qualitatively, lacking numerical or economic quantification. Next, we provide examples of the main services to offer a global overview of their multifaceted value and vulnerability to environmental change. We believe this synthesis provides researchers and practitioners with concrete examples and targeted metaphors to more effectively communicate the importance of subterranean ecosystems to diverse audiences.
