1081. Network modelling unravels mechanisms of crosstalk between ethylene and salicylate signalling in potatoŽiva Ramšak, Anna Coll Rius, Tjaša Stare, Oren Tzfadia, Špela Baebler, Yves Van de Peer, Kristina Gruden, 2018, original scientific article Abstract: To develop novel crop breeding strategies, it is crucial to understand the mechanisms underlying the interaction between plants and their pathogens. Network modeling represents a powerful tool that can unravel properties of complex biological systems. In this study, we aimed to use network modeling to better understand immune signaling in potato (Solanum tuberosum). For this, we first built on a reliable Arabidopsis (Arabidopsis thaliana) immune signaling model, extending it with the information from diverse publicly available resources. Next, we translated the resulting prior knowledge network (20,012 nodes and 70,091 connections) to potato and superimposed it with an ensemble network inferred from time-resolved transcriptomics data for potato. We used different network modeling approaches to generate specific hypotheses of potato immune signaling mechanisms. An interesting finding was the identification of a string of molecular events illuminating the ethylene pathway modulation of the salicylic acid pathway through Nonexpressor of PR Genes1 gene expression. Functional validations confirmed this modulation, thus supporting the potential of our integrative network modeling approach for unraveling molecular mechanisms in complex systems. In addition, this approach can ultimately result in improved breeding strategies for potato and other sensitive crops.

1082. First record of the meagre, Argyrosomus regius (Asso, 1801), in Slovenian coastal waters with additional records from the Croatian part of the Adriatic SeaBorut Mavrič, Branko Dragičević, 2018, original scientific article Abstract: One specimen of meagre, Argyrosomus regius (Asso, 1801), was caught by trawling in the waters off Slovenia on 24th November 2016 at the depth of cca. 20 m above sandy-muddy bottom. This is the fi rst record of this species for the Slovenian part of the Adriatic Sea. Due to the fact that there are no wild populations in the Middle and North Adriatic and that remaining wild populations in the Southern Adriatic are scarce and small, the specimen is supposed to be an escapee from one of the mariculture facilities. Additional occurrences of this species from the Croatian part of the Adriatic Sea are reported.

1083. A new genus and two new species of cave-dwelling cyclopoids (Crustacea, Copepoda) from the epikarst zone of Thailand and up-to-date keys to genera and subgenera of the Bryocyclops and Microcyclops groupsChaichat Boonyanusith, La-orsri Sanoamuang, Anton Brancelj, 2018, original scientific article Abstract: Two obligate cave-dwelling species of cyclopoid copepods (Copepoda, Cyclopoida) were discovered inside caves in central Thailand. Siamcyclops cavernicolus gen. et sp. nov. was recognised as a member of a new genus. It resembles Bryocyclops jankowskajae Monchenko, 1972 from Uzbekistan (part of the former USSR). It differs from it by (1) lack of pointed triangular prominences on the intercoxal sclerite of the fourth swimming leg, (2) mandibular palp with three setae, (3) spine and setal formulae of swimming legs 3.3.3.2 and 5.5.5.5, respectively, and (4) specific shape of spermatophore. Metacyclops thailandicus sp. nov. resembles M. cushae Reid, 1991 from Louisiana (USA). It differs from it by (1) distal segment of the endopod of the fourth swimming leg with one apical spine, (2) the fifth swimming legs with one broad segment, (3) the spine formula of the distal segment of the exopod of the swimming legs 3.4.3.3, and (4) well developed anal operculum reaching articulation with caudal rami. Detailed descriptions of the habitats of the new species and up-to-date keys to the genera and subgenera of the Bryocyclops and Microcyclops groups are provided, along with an updated list of obligate groundwater species of Copepoda in Southeast Asia.
Keywords: Siamcyclops cavernicolus gen. et sp. nov., Metacyclops thailandicus sp. nov., stygobionts, groundwater environment, epikarstic drip

1085. Epibenthic macrofauna on an artificial reef of the Northern Adriatic Sea : a five-years photographic monitoringNicola Bettoso, Lisa Faresi, Ida Floriana Aleffi, Valentina Pitacco, 2023, original scientific article Abstract: Artificial reefs (ARs) are man-made structures used with the aim of improving fisheries and increasing natural production of biological resources. In 2006 an AR made of three types of modules was sunk near an underwater sewage outfall. The objectives of the project were: (a) to use the AR to restock some target species of commercial interest and (b) to promote biodiversity in selected areas. The epibenthic macrofauna that had settled on this AR was annually monitored for five years (2007-2011) using non-destructive photographic methods. A total of 88 taxa from 8 phyla were identified, with a predominance of Porifera, Mollusca and Ascidiacea. Among the types of modules used to construct the AR, polyethylene panel nets were functional for bivalve settlement in the first year, whereas concrete structures seemed to perform best in promoting biodiversity in terms of species richness in the long term. Nevertheless, the 5-year monitoring period was too short to speculate on the stability or homeostasis of communities settled on the AR in terms of ecological succession.

1086. Improvement of the ecological status of the Cymodocea nodosa meadow near the Port of KoperMartina Orlando-Bonaca, Erik Lipej, Romina Bonaca, Leon Lojze Zamuda, 2022, original scientific article Abstract: Seagrass beds are more or less the marine counterpart of tropical rainforests, and their health is related to different anthropogenic stressors, including navigation routes and port activities. In the Mediterranean Sea, Cymodocea nodosa is considered an effective indicator of environmental change, due to its universal distribution, sensitivity to various natural and anthropogenic pressures, and the measurability of the species’ responses to impacts. The aim of this study is to present the changes in the assessment of the ecological status of the C. nodosa meadow near the port of Koper, which was evaluated as Bad in 2018. The results show a significant improvement in the ecological status of the meadow, which can be attributed to a reduction in anthropogenic stressors.

1088. Socioeconomic and environmental importance of the fish market and fisheries in SloveniaAlex Mavrič, Andreja Ramšak, Štefan Bojnec, 2021, original scientific article Abstract: The paper analyses the importance of fisheries and the fish market in Slovenia based on primary information obtained from interviews and secondary data obtained from various sources. The study focuses on the sustainability aspects of fisheries and the fish market in Slovenia, emphasizing socioeconomic factors, problems and anomalies in the market, ecological aspects, and other sustainable development factors as environmental protection and the implementation of sustainable development measures, as well as overfishing and ineffective fisheries management. Most of shortcomings are related to the traceability of fish in the value chain, misleading customers with false information, and price-quality deception. While these findings are country-specific, they have broader implications and highlight opportunities for improving the fisheries and fish market situation in Slovenia and the international trade of fish and fishery products.

1089. New evidence of the occurrence of Knoutsodonta Pictoni (Nudibranchia, Onchidorididae) in the Northern AdriaticAna Fortič, Domen Trkov, Lovrenc Lipej, Marco Fantin, Saul Ciriaco, 2021, original scientific article Abstract: The authors present new data on the recently described nudibranch Knoutsodonta pictoni Furfaro & Trainito, 2017 in the Gulf of Trieste (northern Adriatic Sea). We hereby present the first record of this species in Slovenian territorial waters. A total of 22 specimens of K. pictoni were recorded by diving in the period from 2017 to 2021 at five localities in the Gulf of Trieste. All specimens were found in precoralligenous habitats in the depth range of 5 to 9 m, feeding on the encrusting bryozoan Reptadeonella violacea (Johnston, 1847). Numerous finds indicate that this only recently described and therefore little known nudibranch is much less rare than previously thought.

1090. After more than forty-five years a new finding of Cystoseira foeniculacea f. latiramosa in the coastal sea of SloveniaMartina Orlando-Bonaca, Domen Trkov, 2020, original scientific article Abstract: Canopy-forming macroalgae, especially Cystoseira sensu lato species, create so-called brown algal forests, which are among the most productive habitats in shallow coastal waters. In the Mediterranean Sea these species have been disappearing over the past two decades due to multiple anthropogenic pressures, and are gradually being replaced by smaller and persistent turf-forming algae. A decrease in the number of species and in the cover of canopy-forming taxa (especially Cystoseira s.l. spp.) has been detected over the last ten years also in Slovenian coastal waters. This paper reports a recent finding of Cystoseira foeniculacea f. latiramosa, which was missing from Slovenian marine waters for more than four decades.
