1. Predlog načrta za hitro odzivanje ob najdbi azijskega sršena (Vespa velutina) : Projekt LIFE ARTEMIS, izdelek akcije A2Maarten De Groot, Simon Zidar, Danilo Bevk, Mojca Pibernik, Metka Pislak, Jana Kus Veenvliet, 2020, elaborat, predštudija, študija Povzetek: A proposal of a rapid response plan for the Asian hornet (Vespa velutina) was prepared in the LIFE ARTEMIS Project. The Asian hornet is an invasive alien species which is on the priority list of the IAS EU legislation 1143/2014. In the proposal the EWRR system is described for the finding and the rapid response for the asian hornet. First findings of the asian hornet will be submitted to the information system »Invazivke« or to the National Veterinary Institute (NVI). When data is checked, it will be send to the coordinating governmental body - Slovenian Environment Agency (ARSO) within two days.
During the rapid response proces, two tactical meetings will be organised. First ARSO will inform The Ministry of the Environment and Spatial Planning (MOP) about the finding, which will send it to the European commission. On the first tactical meeting the coordinator for the rapid response actions will be determined. Institute of the Republic of Slovenia for Nature Conservation (ZRSVN) will prepare a first survey in which the status of the population will be determined. Furthermore, all inform general public, landowners and local communities in the invaded area. Within two days to 14 days after the submission of the survey report, the second tactical meeting will be held. During this meeting the possible eradication actions will be discussed and the tasks will be divided. After that the organisation responsible for the rapid response action will prepare the final plan of eradication.
The organisation responsible for the eradication action will take action. Information on the eradication action are written in the report. After that it will be checked whether the eradication was successful. In case this was not, more eradication actions will take place. If it will be successful the area will be monitored for the coming 5 years to be sure that the species is really eradicated. All information will be send to ARSO, who will inform MOP. MOP will inform the European commission and the member states.

5. The ongoing range expansion of the invasive oak lace bug across Europe : current occurrence and potential distribution under climate changeAlbert Ciceu, Flavius Balacenoiu, Maarten De Groot, Debojyoti Chakraborty, Dimitrios N. Avtzis, Marek Barta, Simon Blaser, Matteo Bracalini, Bastien Castagneyrol, Ulyana A. Chernova, 2024, izvirni znanstveni članek Povzetek: In recent years, the oak lace bug, Corythucha arcuata, has emerged as a significant threat to European oak forests. This species, native to North America, has in the last two decades rapidly extended its range in Europe, raising concerns about its potential impact on the continent's invaluable oak populations. To address this growing concern, we conducted an extensive study to assess the distribution, colonization patterns, and potential ecological niche of the oak lace bug in Europe. We gathered 1792 unique presence coordinates from 21 Eurasian countries, utilizing diverse sources such as research observations, citizen science initiatives, GBIF database, and social media reports. To delineate the realized niche and future distribution, we employed an ensemble species distribution modelling (SDM) framework. Two future greenhouse gas scenarios (RCP 4.5 and RCP 8.5) were considered across three-time intervals (2021–2040, 2061–2080, and 2081–2100) to project and evaluate the species' potential distribution in the future. Our analysis revealed that significant hotspots rich in host species occurrence for this invasive insect remain uninvaded so far, even within its suitable habitat. Furthermore, the native ranges of Turkey oak (Quercus cerris L.) and Hungarian oak (Quercus frainetto L.) species offer entirely suitable environments for the oak lace bug. In contrast, the pedunculate oak and sessile oak distribution ranges currently show only 40 % and 50 % suitability for colonization, respectively. However, our predictive models indicate a significant transformation in the habitat suitability of the oak lace bug, with suitability for these two oak species increasing by up to 90 %. This shift underlines an evolving landscape where the oak lace bug may exploit more of its available habitats than initially expected. It emphasises the pressing need for proactive measures to manage and stop its expanding presence, which may lead to a harmful impact on the oak population across the European landscape.

6. The effect of timing of female vibrational reply on male signalling and searching behaviour in the leafhopper Aphrodes makaroviMeta Virant-Doberlet, Maarten De Groot, Andrej Blejec, Ana Kuhelj, 2015, izvirni znanstveni članek Povzetek: Sexual communication in animals often involves duetting characterized by a coordinated reciprocal exchange of acoustic signals. We used playback experiments to study the role of timing of a female reply in the species-specific duet structure in the leafhopper Aphrodes makarovi (Hemiptera: Cicadellidae). In leafhoppers, mate recognition and location is mediated exclusively by species- and sex-specific substrate-borne vibrational signals and a female signal emitted in reply to male advertisement calls is essential for recognition and successful location of the female. In A. makarovi, males have to initiate each exchange of vibrational signals between partners, and in a duet the beginning of a female reply overlaps the end of the male advertisement call. Results of playback treatments in which female replies were delayed and did not overlap with the male call revealed that in order to trigger an appropriate behavioural response of the male, female reply has to appear in a period less than 400 ms after the end of the initiating male call. Results also suggest that males are not able to detect a female reply while calling, since female reply that did not continue after the end of male call triggered male behaviour similar to behaviour observed in the absence of female reply. Together, our results show that vibrational duets are tightly coordinated and that the species-specific duet structure plays an important role in mate recognition in location processes.

7. Cucujus cinnaberinus (Scopoli, 1763) at its terra typica in Slovenia : historical overview, distribution patterns and habitat selectionAl Vrezec, Špela Ambrožič Ergaver, Andrej Kobler, Andrej Kapla, Maarten De Groot, 2017, izvirni znanstveni članek Povzetek: The saproxylic beetle, Cucujus cinnaberinus, has received increasing research attention in Europe since the adoption of the Habitats Directive and establishment of the Natura 2000 network. The history of the species has been investigated as well as the influence of abiotic and biotic variables on the distribution of C. cinnaberinus in Slovenia which is at the limit of its range and also terra typica for the species. The species was first described in 1763 by Joannes A. Scopoli in Carniola, a duchy of the Habsburg Monarchy. Today, most of the territory of Carniola is situated within Slovenia. C. cinnaberinus is particularly common in the eastern part of the country, but very scarce in the mountainous western part. According to historical and recent distribution patterns of C. cinnaberinus in the former Carniolan territory, the region of Ribnica-Kočevje in southern Slovenia is proposed as the most probable type locality of the species. Although the bulk of the C. cinnaberinus population in Slovenia is confined to the lowlands, the species has been found up to 1095 m a.s.l., albeit at a much lower abundance due to the influence of climate and forest structure. Although C. cinnaberinus is a quite an opportunistic species regarding host tree selection, it has been shown to exhibit a preference for Tilia, Populus and Robinia. It is suspected that the high abundance of C. cinnaberinus in lowland floodplain forests is due to the recent human-induced increase in preferred fast-growing and short-lived host trees, i.e. the planting of poplar trees and spread of invasive Black Locust (Robinia pseudoacacia) after the 1960s. In contrast, in montane forests, preferred host trees (e.g. Tilia) represent < 1 % of all growing stock. Although montane C. cinnaberinus populations are rare, they could still be important for the conservation of the species, since montane habitats cover the largest area within the species’ distribution range.

8. Contrasting effects of altitude on species groups with different traits in a non-fragmented montane temperate forestMaarten De Groot, Al Vrezec, 2019, izvirni znanstveni članek Povzetek: Temperature has strong effects on species composition and traits. These effects can differ within and between species groups. Thermoregulation and mobility are traits which can be strongly affected by altitudinal distribution. Our aim was to investigate the influence of altitude on the species richness, abundance and composition of species groups with different trophic, thermoregulatory and mobility traits. Carabids (Coleoptera; Carabidae), hoverflies (Diptera: Syrphidae) and birds (Aves: Passeriformes) were counted in three altitudinal belts with a total elevation difference of 700 m (from 300 m to 1000 m a.s.l.) in the same habitat type (non-fragmented temperate montane mixed beech and fir forest). We found that endotherms and more mobile species (i.e. birds) had a smaller turnover than ectotherms (i.e. hoverflies) and less mobile species (i.e. carabids), from which we can predict that the former species will undergo a less extreme shift than the latter in global warming scenarios. Species turnover across the altitudinal gradient increased from birds to hoverflies to carabid beetles. The effect of altitude on phenology was different between the studied ectotherm species groups (carabids and hoverflies). Hoverflies experience a phenological delay of species richness and abundance at higher altitudes in spring, but not at the end of summer, which implies that hoverfly phenology is affected by a change in temperature, while carabid beetle abundance exhibited a delay in phenology in summer at higher altitudes. We suggest that species that are expected to be most affected by climate change, such as ectotherms and species with poor dispersal ability should be prioritised as the best indicators for monitoring and conservation management purposes.
