42. Climate–growth relationships in Laurus azorica - a dominant tree in the Azorean Laurel forestDiogo C. Pavão, Jernej Jevšenak, Lurdes Borges Silva, Rui Bento Elias, Luis Silva, 2023, original scientific article Abstract: Forests on oceanic islands, such as the Azores archipelago, enable interesting dendroclimatic research, given their pronounced climatic gradients over short geographical distances, despite the less pronounced seasonality. The Lauraceae play an essential ecological role in Macaronesian natural forests. An example is Laurus azorica (Seub.) Franco, a relevant species given its high frequency and physiognomic dominance in Azorean laurel forests. This study aims to quantify climate–growth relationships in L. azorica using a dendroecological approach. We sampled four stands at São Miguel and two stands at Terceira islands, for a total of 206 trees. Following standard dendrochronological methods and rigorous sample selection procedures, we obtained relatively low rbar values and high temporal autocorrelation. Using a stepwise Random Forest analysis followed by Generalized Linear Models calculation, we found prominent effects of present and previous year temperature, but a low precipitation signal on growth rings, with some model variation between stands. Our results agreed with previous observations for broad-leaved species with diffuse porous wood, contributing to increase the baseline dendroecological knowledge about Azorean forests. Due to the high levels of within- and between-stand variation, and to refine the climatic signal analysis, complementary approaches should be explored in the future.

45. Composite landslide in the dynamic alpine conditions: a case study of Urbas landslideEla Šegina, Mateja Jemec Auflič, Matija Zupan, Jernej Jež, Tina Peternel, 2022, original scientific article Abstract: The alpine environment is characterized by complex geology, high-energy terrain, deeply incised river valleys with high erosional potential, extreme weather conditions and dynamic geomorphic processes. Such settings provide favourable conditions for the formation of composite landslides rather than individual slope mass movement phenomena. As an example, we present the kinematics of the composite landslide Urbas in the North of Slovenia which developed in the complex geological and morphological settings characteristic of the alpine environment. The research combines several monitoring techniques and involves the integration of both surface and subsurface displacements measured in the landslide area. The results indicate that the composite sliding process consists of several simultaneous and interrelated types of movements occurring in different segments of the unstable mass that are governed by different mechanisms of displacements, such as rockfall, sliding and debris flow. The kinematic characteristics of a deep-seated landslide that formed in such conditions vary spatially, but is rather homogenuous vertically, indicating translational type of movement. Spatial kinematic heterogeneity is primarily related to the diverse terrain topography, reflecting in different displacement trends. Based on the revealed kinematic proprieties of the sliding material, the sediment discharge illustrates the sliding material balance which estimates the volume of the retaining material that represents the potential for slope mass movement events of larger scales.

47. Tree rings, wood density and climate–growth relationships of four Douglas-fir provenances in sub-Mediterranean SloveniaLuka Krajnc, Jožica Gričar, Jernej Jevšenak, Polona Hafner, Robert Brus, 2022, original scientific article Abstract: Tree rings, wood density and the climate–growth relationship of four Douglas-fir provenances were analysed separately for the juvenile and adult phases. Four provenances were selected from an existing IUFRO provenance trial planted in 1971 based on their diameter at breast height and vitality. Increment cores were extracted from individual trees, on which we measured tree-ring widths (RW), earlywood widths (EWW) and latewood widths (LWW). Wood density was assessed in standing trees using resistance drilling. The climate–growth correlations were calculated between provenance chronologies of RW, EWW, LWW and latewood share, and the day-wise aggregated Standardised Precipitation-Evapotranspiration Index (SPEI). The analysis was done separately for the juvenile and mature phases of growth. Provenances 1064 (Jefferson) and 1080 (Yelm) exhibited larger annual radial increments than provenances 1028 (Merrit) and 1089 (Cathlamet). The two provenances with the highest annual radial increment in the juvenile phase did not exhibit the same trend in the adult phase. In all provenances, RW, and consequently EWW and LWW, were wider in the juvenile than in adult phase. The share of latewood was in all cases higher in juvenile wood than in mature wood. All four provenances had similar wood densities in both analyzed growth phases. Our analysis showed that when selecting the most promising provenance for planting, possible changes in relative growth rate from the juvenile to adult phase need to be considered.

49. Review of the research and evolution of landslides in the hinterland of Koroška Bela settlement (NW Slovenia)Tina Peternel, Ela Šegina, Jernej Jež, Mateja Jemec Auflič, Mitja Janža, Janko Logar, Matjaž Mikoš, Miloš Bavec, 2022, original scientific article Abstract: This paper gives an overview of landslide research and the activity of landslides located above the Koroška Bela settlement in Northwest Slovenia. There are several landslides in this area and they pose a direct threat to the settlement below. The settlement is very densely populated (about 2,100 inhabitants) and has well-developed industry and infrastructure. It is built on deposits from past debris flows, indicating that large slope mass movements have occurred in the past. In this regard, the hinterland of Koroška Bela has been investigated since 2006, within the framework of various research, technical and European projects. The most extensive geological and geotechnical investigations were carried out after April 2017, when part of the Čikla landslide collapsed and mobilised into a debris flow. All of the investigations which have been carried out over the years revealed that the hinterland of Koroška Bela is characterised by high landslide activity due to geological, hydrogeological and tectonic conditions. In order to protect people and their property, it is essential to implement a holistic mitigation measure which includes remediation works (drainage works, debris flow breaker, etc.) and non-structural measures (monitoring system, early warning system, risk management, etc.). Regular and continuous monitoring of all landslides is also crucial to observe the landslide dynamics and evaluate the effectiveness of structural mitigation measures.

50. Long-term survival of a patient with liver metastases from clear cell gastric adenocarcinoma after multimodality treatment including interventional oncology techniques : case reportVesna Jugovec, Jernej Benedik, Jera Jeruc, Peter Popović, 2022, other scientific articles Abstract: Background: Gastric cancer (GC) is the fourth most common cancer and the third leading cancer-related cause of death worldwide since most patients are diagnosed at an advanced stage. The majority of GCs are adenocarcinomas (ACs), and the poorly characterized clear cell AC represents a unique subgroup of GCs and is an independent marker of poor prognosis. Even though the prognosis for patients with advanced GC is poor we present a report of a patient with long-term survival despite having liver metastases from clear cell gastric AC. Case presentation: A 45-year-old male with clear cell gastric AC underwent subtotal gastrectomy and postoperative chemoradiation. Only a year and a half after his initial treatment the disease spread to his liver. He received two lines of chemotherapy treatment within the next two years before a right hepatectomy was suggested. Due to an initially insufficient future liver remnant (FLR), transarterial chemoembolization (TACE) and portal vein embolization (PVE) were performed, which made the surgical procedure possible. Shortly after a disease progression in the remaining liver was detected. In the following three years the patient was treated with a carefully planned combination of systemic therapy and different interventional oncology techniques including selective internal radiation therapy (SIRT) and TACE. And as illustrated, an attentive, patient-tailored, multimodality treatment approach can sometimes greatly benefit our patients as he had an overall survival of 88 months despite the poor prognosis of his disease. Conclusion: To the best of our knowledge, this report is the first to describe a patient with liver metastases from clear cell gastric AC treated with interventional oncology techniques (PVE, TACE, and SIRT) in combination with other locoregional and systemic therapies thereby presenting that these interventional oncology techniques can be successfully integrated into long-term management of non-conventional liver tumors.
