Na območju Triglavskega narodnega parka zasledimo poseben tip travnikov – grbinaste travnike. Zaradi človekove dejavnosti imajo grbinasti travniki ne le naravovarstveno, ampak tudi kulturno vrednost. ...Zato je od leta 2004 v Programu razvoja podeželja (PRP) vzpostavljen sistemski ukrep za ohranjanje grbinastih travnikov. Kmetje so za njihovo vzdrževanje upravičeni do izravnalnih plačil, a je ta podpora nizka, med manj poznanimi in zelo slabo uveljavljenimi. Uradni prostorski sloj grbinastih travnikov je, kljub terenski preveritvi in nadgradnji v letu 2021, necelovit in deloma pomanjkljiv. Namen članka je prikaz nove metode oziroma razvoja kvantitativnega postopka identifikacije grbinastih travnikov na območju Triglavskega narodnega parka. Omejitev postopka je, da ni neposredno uporaben za zaznavanje grbinastih travnikov brez naknadnega terenskega ali digitalnega pregleda. Z njegovo uporabo smo predstavili možnost učinkovite nadgradnje obstoječega uradnega prostorskega sloja grbinastih travnikov.
Several factors are bound to influence a young person’s decision to study a particular study programme, including his or her interests and commitment, abilities and skills, career prospects, family ...expectations, social pressure and peer influence, the information and advice available to him or her and financial constraints. To find out what factors contribute to adolescents’ decision to study geography and the career aspirations of future graduates and postgraduates, a survey was conducted in 2017 and 2020 at the Department of Geography, Faculty of Arts, University of Ljubljana involving a total of 155 students in their first year of the first cycle and the first and the second year of the second cycle. The results will be of great help in the further development of the geography study, as knowledge of the factors influencing their decisions to study, as well as their career aspirations and expectations, will allow us to understand the low enrolment figures in geography studies in recent years (which are not comparable to those of the past in all three Slovenian departments of geography) and to find potential solutions or ways to improve the current situation.
Glavni namen članka je prikaz postopka prepoznavanja in klasifikacije geomorfoloških oblik kopastega krasa na štirih različnih območjih v Sloveniji ter na podlagi morfometrične analize podati nove ...ugotovitve o Dinarskem kopastem krasu. Analiza je potekala s pomočjo programskega orodja ArcMap 10.4.1, kjer smo oblike prepoznali s pomočjo orodja Fill. Avtorja ugotavljata, da je kopasti kras zelo raznolik tip površja, ki se od območja do območja razlikuje. Največji vpliv na oblikovanost vrhov pripisujeta strukturnim geološkim razmeram ter globini vadozne cone.
Although the urban heat island (UHI) phenomenon is more commonly studied in summer, its influence is also important in winter. In this study, the authors focused on the winter UHI in Ljubljana ...(Slovenia) and its impact on the urban population, as well as in comparison with a UHI study from 2000. Through a combination of mobile and stationary temperature measurements in different parts of the city, the winter intensity of the UHI in Ljubljana was studied in a dense spatial network of measurements. It was found that the intensity of the winter UHI in Ljubljana decreases as winters become warmer and less snowy. The results showed that the winter UHI in Ljubljana intensifies during the night and reaches the greatest intensity at sunrise. During the winter radiation type of weather, the warmest part of Ljubljana reaches an intensity of 3.5 °C in the evening. In total, 22% of the urban area is in the evening UHI intensity range of 2–4 °C, and 65% of the urban population lives in this range. In the morning, the UHI in Ljubljana has a maximum intensity of 5 °C. The area of >4 °C UHI intensity covers 7% of the urban area, and 28% of the total urban population lives in this area. Higher temperatures in urban centers in winter lead to a longer growing season, fewer snow cover days, lower energy consumption and cold stress, and lower mortality from cold-related diseases compared to the colder periphery.
Članek prikazuje nov objektiven sistematičen pristop vrednotenja geodiverzitete na primeru območja med Kočevsko Reko in Kostelom. Metoda temelji na prostorski raznolikosti in gostoti elementov ...geodiverzitete ter obenem upošteva razgibanost površja. Metodo smo aplicirali na območju kontaktnega krasa, kjer smo evidentirali vroče točke geodiverzitete. Metodo smo na podlagi evalvacije ocenili kot primerno za vrednotenje geodiverzitete.

This study presents a novel method for the accurate delineation of dolines in karst areas. The method is based on the use of hydrological tools and sky-view Factor in ArcGIS Pro and was implemented ...using a digital elevation model with a resolution of 1 m in four study areas in Slovenia. We manually delineated dolines at four test areas and compared them with the results of the new method, as well as the results of the most commonly used method of hydrological filling and the results of U-Net segmentation. We calculated the average deviation of the perimeter and the differences in the basic morphometric properties. The hydrological filling method cannot be accepted as a suitable method for doline delineation and should only be used for doline identification. The method based on the U-Net segmentation performed better, but the results contain landforms that are not enclosed depressions and therefore cannot be considered as dolines. The new method utilizes the advantages of hydrological filling and at the same time improves the doline delineation. We conclude that the presented method is the most suitable for automatic doline identification and delineation among the automatic methods discussed in this paper. This study further quantifies the enhancements achieved with the new method, highlighting the specific improvements in perimeter accuracy and the reliability of morphometric measurements.

The aim of this study is to examine the influence of the pharmacologic pre-treatment and global brain ischemia on the one hand, and on the other hand, the influence of anaesthesia on the body ...temperature in experimental rats. The study involves 48 white female experimental rats (n=48), strain - Wistar, with body weight ranging from 230 g to 390 g, and age range of 3-5 months. The rats were divided into two groups. All of the rats were anesthetised and underwent various pharmacologic pre-treatments (with erythromycin and physiologic solution) and global brain ischemia with a reperfusion period. The obtained results demonstrate increased body temperature during the anaesthesia, a decrease during ischemia in both groups, and also a significant increase of the temperature 18 hours after the induced global brain ischemia. However, no significant temperature differences were registered between the groups. It can be concluded that the pre-treatment with a single dose of the macrolide antibiotic erythromycin does not cause any significant variations of the body temperature in experimental rats, and this under conditions of anaesthesia and global brain ischemia.
