1. Review of heterobranch molluscs fauna in the Boka Kotorska Bay, MontenegroMilica Jovanović, Vesna Mačić, Domen Trkov, Martina Orlando-Bonaca, Lovrenc Lipej, 2019, review article Abstract: Heterobranch molluscs fauna in Montenegro has been poorly investigated so far. The aim of the present paper is to improve the knowledge about species diversity of these marine organisms in the Boka Kotorska Bay, specific fjord-like entity in the southern Adriatic Sea. New records of seven heterobranch species were obtained by field surveys in 2017, while three new records were provided by analysing underwater photographs from previous periods. The resulted checklist summarizes the knowledge of the diversity of heterobranchs in the Boka Kotorska Bay from the oldest record in 1967 to the present day, and consists of a total of 62 heterobranch species.

2. New records of opistobranch gastropods in the waters off Slovenia (Gulf of Trieste, Northern Adriatic Sea)Lovrenc Lipej, Borut Mavrič, Jan Simič, Domen Trkov, 2014, original scientific article Abstract: The paper deals with four opisthobranch molluscs, which were found in the Slovenian marine waters as new records. The pleurobranchomorph Pleurobranchea meckeli was found on two occasions on muddy detritic bottom in the Gulf of Piran in June of 2013 and 2014. The nudibranch Favorinus branchialis was found in May and June 2014 on turf vegetation in a very shallow area off the pier in Koper harbour. Its spawn with white eggs was also found nearby. The second nudibranch Facelina rubrovittata was found in March 2010 crawling in the intertidal zone of the Nature reserve Strunjan. The third nudibranch Dondice banyulensis was found in waters of the Nature Monument Debeli rtic on sedimentary bottom. With the fi nding of these four species, the total number of opisthobranchs recorded to date in the Slovenian part of the Adriatic Sea increased to 75 species.

3. The groundwater invertebrate fauna of the Channel IslandsAnton Brancelj, Lee R. F. D. Knight, Bernd Hänfling, Colin Cheney, 2015, original scientific article Abstract: The Channel Islands are a small archipelago of British dependencies just off the coast of Normandy at the western end of the English Channel. There were only three records for stygobitic Crustacea [Niphargus fontanus Bate, 1859 and N. kochianus Bate, 1859 from Jersey and N. aquilex Schiődte, 1855 from Guernsey] from the archipelago and no systematic survey has been carried out of the islands for their groundwater fauna till present. Recently sampling was carried out in wells, boreholes and springs on the four largest islands, Jersey, Guernsey, Alderney and Sark during February 2012. Niphargus aquilex was widespread across all four islands and did not appear to be restricted to any particular geology. Niphargus ladmiraulti was present in large numbers in a single borehole on Jersey, the first record of this species from the archipelago. Niphargus kochianus was collected from two sites on Alderney and the syncarid Antrobathynella stammeri (Jakobi, 1954) from two sites on the west coast of Jersey. The records for A. stammeri are new for the Channel Islands and possibly represent the first records of this species from the French bio-geographical area. The presence of N. fontanus on the islands was not confirmed. Several species of stygophilic Cyclopoida were also recorded during the survey along with epigean freshwater invertebrate taxa, which were mostly present in springs and shallow wells close to surface streams.

4. Two new species of parastenocaris (Copepoda, Harpacticoida) from a hyporheic zone and overview of the present knowledge on Stygobiotic Copepoda in Vietnam : historical overview and new dataNgoc-Son Tran, Mau Trinh-Dang, Anton Brancelj, 2021, original scientific article Abstract: The number of freshwater species belonging to the genus Parastenocaris reported from ten countries of Southeast Asia is quite limited. Only two species have been reported so far from freshwater habitats there, compared to over 290 described species of the family Parastenocarididae worldwide. During the first study of the hyporheic zone of two small rivers in central Vietnam, two new species of the family Parastenocarididae were collected, Parastenocaris sontraensis sp. nov. and Parastencaris vugiaensis sp. nov. Both were collected from the gravel bar along the rivers (Suoi Da and Vu Gia river) using the Karaman–Chappuis method. Both the new species belong to the brevipes group of the genus Parastenocaris Kessler, 1913 sensu Lang (1948), and Reid (1995). Parastenocaris sontraensis sp. nov. is similar to P. hinumaensis Kikuchi, 1970 and Parastenocaris jane Karanovic, 2006 in the brevipes-group. Parastenocaris sontraensis sp. nov. differs from both Parastenocaris species by (i) Exp P3 with three segments in the male, (ii) caudal rami with seven setae, and (iii) caudal rami about 2.4 times as long as wide. Parastencaris vugiaensis sp. nov. can be distinguished from its congeners by the unique combination of the following characters: (i) the elliptical shape of caudal rami, (ii) apical seta (V) with bulbous base, and (iii) anal operculum extends beyond the end of anal somite. Until now, 14 stygobiotic species of Copepoda have been recorded in Vietnam (including two new species in this paper), which is relatively few compared with nearby Thailand with 25 species. Short comments on other stygobiotic Copepoda from Vietnam are added.

5. The coastal ichthyofauna of the Mediterranean coral reef : the case of Mljet National Park (Croatia, southern Adriatic Sea)Lovrenc Lipej, Danijel Ivajnšič, Valentina Pitacco, Borut Mavrič, Domen Trkov, Petar Kružić, 2024, original scientific article Abstract: The authors studied the structure of the coastal fish assemblage in a temperate coral reef within a marine protected area in order to provide a baseline information on the occurrence and temporal distribution of fish and to highlight the importance of the coral reef to ichthyofauna. The coastal fish assemblage was investigated at two sites in Veliko jezero (Mljet National Park) in the southern Adriatic Sea with a non-destructive SCUBA visual technique in the period from 2013 to 2021. Altogether, 38 fish taxa were recorded on the right bank (coral reef) and 36 species on the left bank. The presence of the coral reef at a depth range between 9 m to 12 m is the main factor differentiating the fish fauna in these two areas, which are otherwise governed by the same environmental factors. At the coral reef a decrease in fish diversity was discovered with a steady regression from 2013 to 2021.

6. KEYLINK : towards a more integrative soil representation for inclusion in ecosystem scale models : I. : review and model conceptGabrielle I. Deckmyn, Omar Flores, Mathias Mayer, Xavier Domene, Andrea Schnepf, Katrin Kuka, Kris van Looy, Daniel P. Rasse, Maria J.I. Briones, Sébastien Barot, Matty Berg, E. I. Vanguelova, Ivika Ostonen, Harry Vereecken, Laura Martinez Suz, Beat Frey, Aline Frossard, Alexei Tiunov, Jan Frouz, Tine Grebenc, Maarja Öpik, Mathieu Javaux, Alexei Uvarov, Olga Vindušková, Paul Henning Krogh, Oskar Franklin, Juan Jiménez, Jorge Curiel Yuste, 2020, original scientific article Abstract: The relatively poor simulation of the below-ground processes is a severe drawback for many ecosystem models, especially when predicting responses to climate change and management. For a meaningful estimation of ecosystem production and the cycling of water, energy, nutrients and carbon, the integration of soil processes and the exchanges at the surface is crucial. It is increasingly recognized that soil biota play an important role in soil organic carbon and nutrient cycling, shaping soil structure and hydrological properties through their activity, and in water and nutrient uptake by plants through mycorrhizal processes. In this article, we review the main soil biological actors (microbiota, fauna and roots) and their effects on soil functioning. We review to what extent they have been included in soil models and propose which of them could be included in ecosystem models. We show that the model representation of the soil food web, the impact of soil ecosystem engineers on soil structure and the related effects on hydrology and soil organic matter (SOM) stabilization are key issues in improving ecosystem-scale soil representation in models. Finally, we describe a new core model concept (KEYLINK) that integrates insights from SOM models, structural models and food web models to simulate the living soil at an ecosystem scale.

7. An overview of alien Diptera in SloveniaMaarten De Groot, 2013, original scientific article Abstract: The nonindigenous Diptera occurring in Slovenia are overviewed based on literature data. In total, 18 species belonging to eight Diptera families are alien to Slovenia. Most of the species originate from North America and continental Asia. The first record of an alien Diptera species (Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae)) was made in 1959, but the bulk of the species were recorded for the first time in the last two decennia. Most of the species were found in the pre-Alpine and sub-Mediterranean regions. The distribution and abundance of the alien Diptera are not fully known, as in most cases only the first observations were published. Most of the species are phytophagous and are known pests in agriculture and forestry. A list of expected nonindigenous Diptera species for Slovenia is given. It is suggested that a monitoring system should be developed in order to understand the population dynamics and the impact of the alien species on the ecosystem and economy.

8. Additions and omissions to the list of hoverfly fauna (Diptera: Syrphidae) of SloveniaMaarten De Groot, Roman Luštrik, Tim Faasen, Dare Fekonja, 2010, original scientific article Abstract: The changes in the checklist of hoverflies of Slovenia are presented. Fifteen species are recorded as new for the fauna of Slovenia: Brachyopa panzeri, Brachypalpus laphriformis, Callicera aenea, Chamaesyrphus scaevoides, Chalcosyrphus valgus, Melangyna lasiophthalma, Meligramma guttata, Merodon aberrans, Parhelophilus frutetorum, Orthonevra intermedia, Platycheirus occultus, Rhingia borealis, Spazigaster ambulans, Sphaerophoria chongjini and Sphaerophoria fatarum. From the species complex of Merodon aeneus, both M. aeneus species A/B and M. aeneus C were recorded. One species, Xylota caeruliventris, was omitted from the checklist because of misidentification. Information on habitat characteristics, range and conservation status is givenfor every new species.
