1. A checklist of isopods (Crustacea: Isopoda) in SloveniaMiloš Vittori, Borut Mavrič, Anja Pekolj, Marijan Govedič, Maja Zagmajster, 2023, izvirni znanstveni članek Povzetek: Isopods are a diverse peracarid crustacean group with marine, freshwater and terrestrial representatives. Isopod species lists were typically prepared according to different habitats, which was true also for Slovenia. Here, we prepared the first unified overview of isopod species for Slovenia, which is also the first list of marine isopods in the country. We examined scientific publications, research reports and institutional databases. A total of 126 species have been recorded in Slovenia, of which 31 are marine, 21 are found in freshwater, and 74 are terrestrial. Of these, we report on seven marine and one terrestrial species for the first time. A major part of freshwater isopod richness is linked to the subterranean environment, where most endemic species for the country can be found. Among marine species, many are parasites, with potential economic impact, and two species are considered introduced. When the new species list is considered with valid national legislation, only 41 species retained the same taxonomic status. Many synonyms and invalid taxa according to recent taxonomy point out the need for revision the national red list of Malacostraca as well as other nature protection acts.

2. An updated checklist of the extant freshwater ostracods (Podocopida, Ostracoda, Crustacea) of SloveniaNataša Mori, Ali Šalamun, 2022, izvirni znanstveni članek Povzetek: The article presents an updated checklist of the extant freshwater ostracods in Slovenia. The data were obtained from the published scientific literature up to 2012 and from field collections after 2012, mainly from springs and groundwaters and, to a lesser extent, from ponds and other surface waters. The erroneous and invalid species names cited in the existing literature are listed to avoid further misquotations. The updated checklist contains a total of 70 valid species names. The species belong to 3 superfamilies, 9 families and 32 genera. The species-richest is the family Candonidae (36 species), followed by the family Cyprididae (22 species). Further field samplings are needed to complete the species list, with the focus on the eastern and southeastern parts of Slovenia, and on the sampling of surface waters. Additionally, more in-depth literature investigations and examinations of old museum collections across Europe need to be carried out to obtain all existing data. Moreover, many stygobiotic species (i.e., species inhabiting exclusively subterranean waters), new for science, collected over the last 20 years, need to be scientifically described. Lastly, the Slovenian National Red list on ostracods needs to be urgently updated.

3. Biological invasions are a population-level rather than a species-level phenomenonPhillip Joschka Haubrock, Ismael Soto, Danish A. Ahmed, Ali R. Ansari, Ali Serhan Tarkan, Irmak Kurtul, Rafael L. Macêdo, Adrián Lázaro-Lobo, Mathieu Toutain, Ben Parker, Natalia I. Kirichenko, 2024, izvirni znanstveni članek Povzetek: Biological invasions pose a rapidly expanding threat to the persistence, functioning and service provisioning of ecosystems globally, and to socio-economic interests. The stages of successful invasions are driven by the same mechanism that underlies adaptive changes across species in general—via natural selection on intraspecific variation in traits that influence survival and reproductive performance (i.e., fitness). Surprisingly, however, the rapid progress in the field of invasion science has resulted in a predominance of species-level approaches (such as deny lists), often irrespective of natural selection theory, local adaptation and other population-level processes that govern successful invasions. To address these issues, we analyse non-native species dynamics at the population level by employing a database of European freshwater macroinvertebrate time series, to investigate spreading speed, abundance dynamics and impact assessments among populations. Our findings reveal substantial variability in spreading speed and abundance trends within and between macroinvertebrate species across biogeographic regions, indicating that levels of invasiveness and impact differ markedly. Discrepancies and inconsistencies among species-level risk screenings and real population-level data were also identified, highlighting the inherent challenges in accurately assessing population-level effects through species-level assessments. In recognition of the importance of population-level assessments, we urge a shift in invasive species management frameworks, which should account for the dynamics of different populations and their environmental context. Adopting an adaptive, region-specific and population-focused approach is imperative, considering the diverse ecological contexts and varying degrees of susceptibility. Such an approach could improve and refine risk assessments while promoting mechanistic understandings of risks and impacts, thereby enabling the development of more effective conservation and management strategies.

4. Matrix type affects carabid beetle community and trait composition, and intraspecific variation in remnant forestsD. Johan Kotze, Matic Gabor, S. Kohout, Heikki Setälä, 2024, izvirni znanstveni članek Povzetek: Aim: The Anthropocene is characterised by urban and agricultural landscapes. Within these landscapes, natural to semi-natural habitats are fragmented, isolated and disturbed to varying degrees. Species associated with these natural habitats have to content with the surrounding landscape, both in terms of level of isolation, and matrix type and quality. We investigated the community structure, trait distribution and individual traits of carabid beetles in boreal forest fragments within three matrices: urban, agricultural and freshwater lake. Location: City of Lahti and its surroundings, southern Finland. Taxon: Coleoptera, Carabidae. Methods: Using pitfall traps from June to October 2019, we collected carabid beetles from eight spruce-dominated forest fragments in the urban matrix, 10 fragments in an agricultural matrix, seven fragments on lake islands and three large control forests at the outskirts of the city. Results: Compared to natural forests, carabid beetles in forest fragments in these matrices showed distinct assemblages, and with beetle diversity the highest in fragments in the agricultural landscape. Fragments in the urban and lake island landscapes were characterised by small-sized species, and those capable of flight. We also found strong intraspecific trait responses in terms of body size, with some generalist species being significantly smaller in urban, agricultural or lake island fragments compared to the controls. Main Conclusions: The matrix has a clear effect on carabid beetle communities, both in terms of taxonomic and trait distribution, and filters for communities of smaller sized species and those capable of flight. Such overall community and intraspecific effects can have considerable effects on populations and community assemblages: As anthropogenic effects intensify in urban and agricultural landscapes, our findings may be the expression of further morphological and physiological responses, and eventually in the adaptation of those species that can cope with the Anthropocene.
