231. Occurrence of giant tun, Tonna galea (Linnaeus, 1758) (Gastropoda: Tonnidae) in the marine waters off Slovenia (northern Adriatic Sea)Manja Rogelja, Lovrenc Lipej, 2019, izvirni znanstveni članek Povzetek: On 1st December 2018 a fisherman caught a specimen of the giant tun Tonna galea (Linnaeus, 1758) in the bottom trammel net for flounders, approximately 1 Nm outside the town of Izola. The net was placed on a muddy bottom at 20 m of depth. This is the second record of T. galea in the Slovenian waters (Gulf of Trieste, northern Adriatic Sea). Another specimen (the first one) was previously reported in October 2015 in the waters off Piran. By including T. galea in the checklist of Slovenian marine malacofauna, at least 370 gastropod species were up to date recorded in the Slovenian part of the Adriatic Sea.

232. Biometry and population gender structure of three crab species (Crustacea: Decapoda) from sandy bottom in the northern Adriatic SeaMona Rezaei, Al Vrezec, Borut Mavrič, Lovrenc Lipej, 2019, izvirni znanstveni članek Povzetek: The aim of the study was to investigate the distribution and population structure of three species of crabs (Decapoda: Crustacea), Medorippe lanata, Liocarcinus depurator and Liocarcinus vernalis for their biometric relationships. A total of 1100 specimens of three species were caught from waters off the northern Adriatic Sea in December 2013. Biometric relationships and condition factor (Fulton’s coefficient index) were measured for all the studied species. Size dimorphism was also observed in M. lanata with females showing significantly larger carapace size than males without significant difference in wet weight. The studied species did not differ significantly in the results of the condition index.

236. Assessment of bryozoan xenodiversity in the Slovenian coastal seaAna Fortič, Domen Trkov, Borut Mavrič, Lovrenc Lipej, 2019, izvirni znanstveni članek Povzetek: The phylum Bryozoa is one of the less studied macroinvertebrate groups in the Slovenian coastal sea. However, these animals play an important role in marine coastal ecosystems, especially as bioconstructors and filter feeders. Non indigenous species represent five to ten percent of all Mediterranean bryozoan species. In this paper, we present an updated list of non-indigenous or cryptogenic bryozoan species recorded in Slovenia. The list includes six species: Amathia verticillata, Bugula neritina s.l., Celleporaria brunnea, Tricellaria inopinata, Watersipora arcuata and Watersipora subtorquata with comments on their morphology, ecology and distribution in the Slovenian coastal sea. Introduction vectors and possible dispersal mechanisms are discussed, as well as methodological approaches and problematic areas as regards the study of non-indigenous bryozoans. Three species reported here, A. verticillata, C. brunnea and W. subtorquata, represent the first confirmed record from the Slovenian Sea Ključne besede: non-indigenous species, Bryozoa, northern Adriatic Sea, harbour habitats, mussel farms, experimental plates Objavljeno v DiRROS: 31.07.2024; Ogledov: 151; Prenosov: 137

237. Impact of the port of Koper on Cymodocea nodosa meadowMartina Orlando-Bonaca, Janja Francé, Borut Mavrič, Lovrenc Lipej, 2019, izvirni znanstveni članek Povzetek: In the Mediterranean Sea Cymodocea nodosa is considered a valid indicator of environmental changes, due to its extensive distribution, sensitivity to different pressures, and measurability of species responses to those stressors. Navigation routes are recognized among the main pressures on the status of C. nodosa meadows in the Gulf of Trieste, related to a high resuspension of sediments and, in consequence, high water turbidity and reduced light levels. The MediSkew index was applied to samples collected in the C. nodosa meadow growing near the Port of Koper, and the ecological status was evaluated. The results were compared to those obtained for the C. nodosa samples from the reference site in the Gulf of Trieste, the Strunjan Nature Reserve.

238. Identification of wood Rot fungi in the historic Baker Memorial Hall at the University of the Philippines, Los Baños CampusMark Paul Selda Rivarez, Elizabeth Parac, Shajara Fatima M. Dimasingkil, Cheek S. Fadriquela, 2019, izvirni znanstveni članek Povzetek: Deterioration in heritage wood structures caused by wood-decay fungi is a worldwide concern. In the University of the Philippines Los Baños, decay fungi from wooden canopies of the Baker Memorial Hall were identified and its degrading ability was evaluated. Specimen collection was conducted on degraded canopies made of Mayapis (Shorea palosapis) with signs of white or green fungal growth. Fungi associated with the rotting symptoms were isolated, purified, characterized and identified. Colonies of fungal isolates were fast-growing in malt extract agar (MEA), with colony diameter reaching 5.60 % 0.43 cm (WRF8) and 5.15 % 0.25 cm (WRF5) after a day. Mycelia of isolates were hyaline and rhizoidal on water agar. Isolate WRF5 produced green, raised colonies that imparted yellow pigmentation on potato dextrose agar (PDA) and MEA. Generally, colonies were raised, radially striated with green center and white margin on PDA. Average length and width of WRF5 conidia were 3.19 % 0.33 %m and 2.73 % 0.36 %m, respectively. Cross-referencing morphological and cultural data with related literatures and identification keys indicated the isolated fungi were Trichoderma viride (WRF1), T. crassum (WRF3), T. reesei (WRF5), Rhizopus sp. (WRF8) and Coniophora sp. Furthermore, inoculation of 108 T. reesei conidia/mL on clean Mayapis wood blocks resulted to profuse fungal growth, with average weight loss recorded at 8.81 % 0.79% at 8 wks and 10.53 % 0.88% at 14 wks which indicated a considerable but slow wood degradation.

239. Recent changes (2013-2017) in scyphomedusan fauna in the Boka Kotorska Bay, Montenegro (Southeast Adriatic)Ivana Violić, Tjaša Kogovšek, Branka Pestorić, Vesna Mačić, Ivona Milić Beran, Davor Lučić, 2019, izvirni znanstveni članek Povzetek: A semi- quantitative time series (2013-2017) was used to present the recent events of scyphomedusae appearance and abundance in the Boka Kotorska Bay, Montenegro, Southeast Adriatic. Six meroplanktonic species were recorded: Aurelia spp, Chrysaora hysoscella, Cotylorhiza tuberculata¸ Discomedusa lobata, Drymonema dalmatinum and Rhizostoma pulmo. Among them, C. hysoscella and D. lobata dominated in the water column during winter and spring, forming dense aggregations in March and May, and February to May, respectively. Our description of the D. lobata blooms are actually the first known records of blooms for this species. C. tuberculata was observed in the Bay principally in August and September. The bloom was occurred only in 2017, being the first information of C. tuberculata mass appearance in this area. We hypothesized that global warming phenomena could trigger the observed changes, and in this respect, long-term trends of sea surface temperature (SST) fluctuations were analysed. The scyphomedusae blooms coincided with high positive SST anomalies, noted in the last seven years for this area. To better understand the mechanisms underlying changes in their phenology and abundance, detailed studies on benthic stages in the Bay are essential.

240. The titre of the virus in the inoculum affects the titre of the viral RNA in the host plant and the occurrence of the disease symptomsMaruša Pompe Novak, Maja Križnik, Kristina Gruden, 2019, izvirni znanstveni članek Povzetek: Potato virus Y (PVY) is the most economically important potato virus, therefore extensive research is focusing on elucidation of its interaction with the host. To obtain repeatable results, strict standardization of research methods is crucial. Mechanical inoculation by rubbing sap from a PVY infected plant onto the leaf surface together with a fine abrasive powder is the most convenient way of experimental transmission of PVY to host plants. However, factors determining reproducibility of this process need to be determined. In the present study, it was shown that higher titre of the virus in the inoculum resulted in faster increase of PVYNTN RNA titre in the inoculated leaves, as well as in faster translocation of PVYNTN from inoculated leaves into upper non-inoculated leaves. The final titre of PVYNTN RNA in upper non-inoculated leaves was independent of the virus titre in the inoculum. In addition, the occurrence of the disease symptoms was followed and the dependence to the titre of the virus in the inoculum was observed.
