Prediction of land use and land cover change using artificial neural networks on the example of two sub-catchments of the Južna Morava river
No full textPlanovi upravljanja vodama na slivu podrazumevaju i izučavanje budućih klimatskih uslova.
Rezultati novijih istraživanja ukazuju da na nivou sliva, osim promene klime, na budući vodni režim značajnu
ulogu imaju i promene namene zemljišta i zemljišnog pokrivača. U radu su tretirana dva ruralna podsliva reke
Južne Morave do profila hidrološke stanice (HS) Visoka na reci Jablanici i HS Sijarinska Banja na reci Kosanici.
Cilj rada je da se predvide promene namene zemljišta do kraja 2100. godine na osnovu satelitskih snimaka iz
2001., 2010. i 2020. godine. Predviđanje je bazirano na rezultatima koji su dobijeni primenom neuronskih mreža
kroz dodatak MOLUSCE u softverskom paketu QGIS v2.18. Razmatrane su četiri varijante ulaznih podataka
dobijene kombinovanjem: digitalnog modela visina, odstajanja od puta, ekspozicije i nagiba terena. Dobijene
vrednosti koeficijenta kapa i procentualne tačnosti modela ukazuju na saglasnost osmotrenih i simuliranih
podataka. Na teritoriji oba slivna područja značajne efekte u postupku predviđanja promene namene zemljišta ima
odstojanje od puta. Rezultati simulacija u različitim vremenskim presecima do 2100. godine upućuju na porast
površina pod gustom šumom, što potencijalno može uticati na proces formiranja oticaja u budućnosti
The tautomeric preferences of 5-benzylidenebarbituric acid derivatives: experimental and quantum chemical studies
No full textBarbiturna kiselina i njeni sintetički derivati privlače veliku pažnju zbog svojih
jedinstvenih strukturnih svojstava i značajne tehnološke i farmaceutske upotrebe.
Spektrofotometrijskom titracijom u vodenom rastvoru određene su pKa vrednosti derivata
5-benzilidenbarbiturne kiseline (5-BBA) sa najjačim elektron-donorskim supstituentom u
ispitivanoj seriji. Primetno visoka vrednost pKa3 (12,27±0,02) sugeriše da u rastvoru
preovlađuje triketo oblik. Osim toga, 13C NMR analiza u DMSO-d6 potvrdila je triketo
oblik kao dominantnu tautomernu vrstu. Kvantno hemijski proračuni korišćenjem MP2/6-
311G(d,p) metode potvrdili su da je triketo oblik najstabilniji tautomer 5-BBA. Proračuni
su takođe pokazali da su diketo i monoketo tautomeri destabilizovani za 15,4-20,6
kcal/mol i 32,5-35,8 kcal/mol, respektivno
Public involvement in planning, management and maintenance of trees, forests and green space in urban areas – attitudes of professionals in 10 European countries
No full textA survey with 582 professionals dealing with various aspects of planning, management and
maintenance related to trees, forests and green space in urban areas was conducted in 10 European
coutries. The goal was to explore i) what experiences professionals had with public involvement,
ii) what attitudes professionals had towards public involvement in various activities related to trees,
forests and green space in urban areas, iii) how they perceive potential advantages and challenges of
public involvement, iv) what traits they would expect from potential volunteers, and v) the influence of
sociodemographic characteristics of respondents on their attitudes. The results showed, among other,
that professionals highly support activities such as monitoring of incivilities, raising awareness and
campaigning or litter picking. On the other hand, participation in tree assessment, monitoring of tree
pests, diseases and invasive alien species, as well as tree inventorieis were the least supported. Some
sociodemographic varibles proved pertinent for professionals’ attitudes towards public involvement.
Further and in-depth studies are needed for more detailed interpretation of professionals’ attitudes and
differences among countries
Evaluating the potential for exterior use of plywood panels composed of thermally modified poplar veneers
No full textThis research examines the influence of brown rot fungus Serpula lacrymans and white rot fungus
Trametes versicolor on durability of plywood panels composed of thermally modified poplar veneers.
Five types of five-layer plywood panels have been tested, the control panel made of unmodified poplar
veneers and four plywood panels composed of thermally modified veneers at temperatures of 190,
200, 210 and 215° C. The results showed that the impact of thermal modification was positive, and that
this environmentally acceptable process increases the durability of the treated material against wood
destroying basidiomycetes fungi
Correction to: The influence of exploration activities of a potential lithium mine to the environment in Western Serbia (Scientific Reports, (2024), 14, 1, (17090), 10.1038/s41598-024-68072-9)
No full textCorrection to: Scientific Reportshttps://doi.org/10.1038/s41598-024-68072-9, published online 24 July 2024 The original version of this Article contained errors. Original Ref 10 was not appropriate reference to support the statement where it was cited. It is therefore now replaced by a new Ref 10, and new Ref 11 and 12 are further added to support this statement. As a result, in the Introduction, “The easiest and least environmentally damaging method of exploiting lithium is from brines, while exploitation from ore rocks has severe environmental consequences10.” now reads: “The easiest and least environmentally damaging method of exploiting lithium is from brines, while exploitation from ore rocks has severe environmental consequences10,11, 12.” and in References, “10.

Secondly, as a result of a mix-up with data sources the special coverage of the Jadar project was incorrectly estimated. Additionally, one of the numbers was given incorrectly due to a typo. This is now corrected using original Ref 28 (now Ref 30) as a sole source of information. In ‘Ecological risk assessment of the Jadar lithium mine in Western Serbia’, “The preliminary estimated spatial coverage of the Jadar project is between 2031 and 2431 ha, with 533 ha of land expected to be destroyed during the initial phase of the project implementation. Of the land to be destroyed, 203 ha are forests, and 317 ha is arable land.” now reads: “The preliminary estimated spatial coverage of the Jadar project is 2031, with 533 ha of land expected to be destroyed during the initial phase of the project implementation. Of the land to be destroyed, 206.5 ha are forests, and 173 ha is arable land.” Additionally, original Ref 27 was incorrectly used in the same section. It was now removed – original Ref 31 (now Ref 33) cited at the end of the paragraph supports it in its entirety. As a result, in ‘Ecological risk assessment of the Jadar lithium mine in Western Serbia’, “The planned “Jadar” project is expected to cause significant habitat destruction and fragmentation, resulting in severe negative impacts on the living world, including several hundred plant and animal species. Among these species, 145 have protected and strictly protected status27. The project would also threaten the isolated eastern enclave of T. scorodonia, a sub-Atlantic species located more than 600 km away from the nearest western population. Additionally, the rare fern Dryopteris and 20 other rare species would disappear from the site of the planned tailings lands, as reported by Krizmanić et al. in 202131.” now reads: “The planned “Jadar” project is expected to cause significant habitat destruction and fragmentation, resulting in severe negative impacts on the living world, including several hundred plant and animal species.

Additionally, the rare fern Dryopteris and 20 other rare species would disappear from the site of the planned tailings lands, as reported by Krizmanić et al. in 202133.” Incorrect annual production tonnages were used when discussing the previous feasibility study. In ‘Eco‑chemical risk of jadarite mining and lithium extraction’, “Based on a feasibility study45, the annual production of Li2CO3 would be 50,000 t/year, and B(OH)3 production would reach 248,000 t/year.” now reads: “Based on a feasibility study47, the annual production of Li2CO3 would be 58,000 t/year, and B(OH)3 production would reach 286,000 t/year.” Additionally, in the same section, “We predict that with the mine opening, in addition to the presented problems that will multiply, new problems would arise due to pond tailings the company plans to place next to the two torrential rivers Korenita and Jadar and also in Štavica River valley uphill from the lithium boron mine and ore processing plant.“ now reads “We predict that with the mine opening, in addition to the presented problems that will multiply, new problems would arise due to tailings the company plans to place next to the two torrential rivers Korenita and Jadar and also in Štavica River valley uphill from the lithium boron mine and ore processing plant. The landfill in Štavica river would block river’s free flow and create a pond.” In ‘Socio‑environmental risks of Rio‑Tinto’s jadarite mining project in Serbia’, “During the initial stages of the proposed mining project, some residents allowed sample drilling on their properties without realizing that their land was located on the planned tailings pond.” now reads: “During the initial stages of the proposed mining project, some residents allowed sample drilling on their properties without realizing that their land was located on the planned tailings.” In original Ref 31 (now Ref 33), an initial of one of the authors was incorrect: “Anđelković, A.” in the author list now reads “Anđelković, M”. Finally, in the Supplemental Information 1, a methodological description of the sample collection and preparation, ICP-OES measurements, and calibration was also included (as a result, SI file contains new References 4–10; subsequent references were re-ordered accordingly). The original version of this Article and the associated supplementary materials were corrected.Correction to: [https://doi.org/10.1038/s41598-024-68072-9]Correction to: [https://technorep.tmf.bg.ac.rs/handle/123456789/7580
Akademski uspon koncepta "15-minutnog grada" kao odgovor na izazove pandemije COVID-19
No full textPandemija COVID-19 istakla je brojne strukturne nedostatke u savremenim gradovima, uključujući nejednak pristup osnovnim uslugama i nedovoljno razvijenu infrastrukturu za lokalne zajednice. Kao odgovor na ove izazove, koncept „15-minutnog grada”, koji omogućava da se sve svakodnevne potrebe zadovolje unutar 15 minuta hoda ili vožnje biciklom, postao je važan predmet istraživanja u urbanističkom planiranju. Ovaj rad analizira rastuću popularnost i naučni značaj koncepta, koristeći podatke iz Scopus baze koji sadrže pojam „15-minutni grad”. Dobijeni rezultati pokazuju značajan porast akademskog interesovanja nakon 2020. godine, što se može dovesti u vezu sa izazovima koje je pandemija donela. Istraživanje obuhvata analizu publikacija u različitim naučnim oblastima, poput društvenih nauka, tehničkih disciplina i nauka o životnoj sredini, te se osvrće na primenu koncepta u gradovima gde je pandemija COVID-19 poslužila kao katalizator za usvajanje održivijih urbanih modela. Rezultati istraživanja ukazuju da je koncept „15-minutnog grada” postao centralna tema u urbanističkim raspravama, zahvaljujući svojoj interdisciplinarnoj prirodi koja objedinjuje društvene, ekonomske i ekološke aspekte, i predstavlja značajan korak ka stvaranju otpornih i pristupačnih gradskih sredina
Strategic framework for preservation and development of the green infrastructure of urban landscapes
No full textSavremeni gradovi su poslednjih decenija izloženi brojnim uticajima, prevashodno rastom populacije i klimatskim promenama, koji rezultiraju stanjem u kome opšti kvalitet njihove životne sredine kao i kvalitet života stanovnika sve više dobijaju negativne aspekte. Zelena infrastruktura je kao planerski koncept već dug period prepoznata kao mera uspostavljanja zdravijeg životnog okvira urbanih predela uz uvažavanje osobenosti i potencijala servisa prirodnih i prirodi bliskih ekosistema. Potraga za uspostavljanjem regulatornog okvira zelene infrastrukture uz primenu savremenog multidisciplinarnog i skalabilnog pristupa je proces koji se odvija širom sveta. Na bazi principa međunarodnih i nacionalnih konvencija i direktiva i analize svih administrativnih i fi zičkih konstitutivnih elemenata zelene infrastrukture, izrađena je Strategija zelene infrastrukture grada Beograda koja je usvojena od strane uprave grada. Strategija je na bazi svih identifi kovanih problema u implementaciji koncepta, defi nisala posebne ciljeve u okviru kojih su prepoznate strateške smernice za ostvarivanje servisa urbanih ekosistema. Primenom mera i aktivnosti koji su propisani strategijom, otpočinje proces formiranja složenog regulatornog i stručnog očuvanja i razvoja zelene infrastrukture grada i formiranja rezilijentnog urbanog predela Beograda
Post-release dispersal and home range of translocated red deer in the Vojvodina province (Serbia)
No full textMonitoring of 38 (12 male and 26 female) red deer translocated from Ivo Wildlife Park (Romania) to hunting ground “Bosutske Forest” (Vojvodina, Serbia) was conducted from 2017 to 2021. The red deer were translocated in lieu of the managing authority’s efforts to counteract the effects of red deer losses due to catastrophic flooding in the region. All animals were ear-tagged, while 7 males and 10 females were fitted with GPS collars. A total of 2,288 valid signals were analyzed (565 from males and 1,723 from females). In addition, 1,333 sighting records were collected from eight observation posts (480 in 2019, 670 in 2020 and 183 in 2021). We determined the movements and spatial distribution of translocated animals in the new habitat and estimated their home range sizes. Home range was calculated using the minimum convex polygon method, while the core area was calculated using the kernel density estimator method. The greatest straight-line distance from the acclimatisation enclosure was essentially the same for both sexes (average 6.0 km for males and 6.4 km for females). A non-significant relationship existed between the number of days in captivity and the greatest straight-line distance, as well as between days in captivity and the core area of the home range. The estimated home range of males was 12.8 km2 (range 0.2‒36.1), smaller than that of females (20.6 km2, range 0.4‒68.7), but this difference was not statistically significant. Observations made independently showed mostly herds of 4 to 6 individuals (52.3%), while large herds (≥ 10 individuals) were rare. Participation of translocated and resident animals in mixed herds was common during the monitoring period (62.3%). Our results showed that a high level of acceptance of the new habitat and social cohesion between translocated and resident animals was achieved. We believe that this is due to two main reasons: firstly, the long-term stay in a large acclimatisation enclosure prior to release and secondly, year-round supplemental feeding coupled with an abundant natural food supply in this unique forest area also contributed to successful acclimatisation
Practices for Phytoremediation of Soil in Serbia
No full textPhytoremediation stands as a crucial tool for addressing pollution, yet its application in Europe remains inadequately explored. Taking Serbia as a test case, this literature review delves into the state of knowledge regarding phytoremediation, exploring the regional distribution of contaminated sites, the prevalence of analysed contaminants, and the diversity of plant species employed for phytoremediation. Analysis revealed 24 distinct locations, 11 sampling parts, scrutiny of 24 potential toxic elements (PTEs) and nutrients, and the involvement of 65 plant species. Predominantly, research sites were associated with industrial areas, particularly mining sites. The efficacy of various plants varied across multiple factors, with soil, roots, and leaves emerging as the most frequently sampled components in reviewed manuscripts. Notably, the scientific literature emphasized Cu, Zn, Cd, and Pb as the most frequently studied PTEs in the context of phytoremediation. This review underscores the need for increased attention to phytoremediation research in Serbia, advocating a more widespread and intensive exploration, both geographically and in research efforts. The compilation of plant species employed for phytoremediation offers valuable insights into the effectiveness of particular species in distinct phytoremediation practices
Adaptive potential of European beech in a provenance trial established in Serbia
No full textKey MessageIn a provenance trial conducted in Serbia, the provenance of the beech trees exhibited a stronger influence on leaf morphology than on survival rate.AbstractProvenance trials are crucial for understanding the genetic diversity within beech provenances and advising forestry management practices. In this study, by integrating leaf morphometric analyses and survival data from a 16-year-old provenance trial in Serbia, we aimed to uncover patterns and mechanisms that govern plant-environment interactions in beech (Fagus sylvatica L.) ecosystems. The provenance trial used in this study was established in 2007, as part of the broader European network, from seedlings of 22 provenances originating across Europe. In the fall of 2007 and 2010, and in the summer 2023, plant vitality was recorded within each provenance. For geometric morphometrics, leaves were collected in 2023. The analyses tested the effects of provenance, provenance geographical origin, and provenance survival trend on leaf size and shape. The results showed significant variation in leaf size and shape and revealed that while there was no clear pattern of correlation between survival percentage and leaf morphology, provenance origin did show significant influence on leaf size and shape. Additionally, source stands environmental factors exerted a stronger influence on leaf shape than on leaf size variation. The observed variability in beech leaf morphology on one side, and survival rates on the other side, serve as indicators of the species' resilience and ability to adjust to changing environmental conditions
