20.500.12556/DKUM-98495 Long‑term changes in the timing and intensity of the pollen season in Slovenia (2002–2024) Climate change is reshaping pollen season dynamics across Europe, with significant implications for allergic populations. This study presents the first comprehensive long-term analysis of pollen season trends in Slovenia, a region characterized by high phytogeographic diversity at the intersection of Mediterranean, Alpine, Dinaric, and Pannonian climatic influences. Daily airborne pollen concentration data from three monitoring stations were analyzed for 14 allergenic taxa over 23 years (2002–2024). Pollen season timing was determined using a normalized cumulative-sum approach, and linear regression quantified temporal trends in season onset, termination, duration, and total annual pollen load. Results reveal general advancement in season onset across most taxa, particularly pronounced for arboreal species in the Mediterranean region. Season termination exhibited asymmetric patterns: earlier endings for spring-flowering trees and delayed termination for herbaceous taxa, especially Poaceae. Notably, trees showed compressed seasons due to faster advancement of season end relative to onset, potentially leading to more intense allergen exposure despite shorter duration. Significant increases in annual pollen load were detected for Poaceae, Urticaceae, and Plantago, while Artemisia showed widespread decline. The coastal Mediterranean site exhibited significantly earlier onset, later termination, and longer seasons compared to continental stations, which showed strong inter-site synchrony. These findings demonstrate asymmetric seasonal responses to climate forcing across small spatial scales, with important implications for region-specific public health strategies. airborne pollen pollen trends pollen season Slovenia mediterranean climate continental climate cvetni prah v zraku trendi cvetnega prahu sezona cvetnega prahu Slovenija sredozemsko podnebje celinalno podnebje true false true Pitagora Editrice Angleški jezik Slovenski jezik Znanstveno delo 2026-06-17 06:53:48 2026-09-10 14:51:42 2026-09-11 03:08:00 0000-00-00 00:00:00 2026 0 0 str. 1-19 št. članka 35 Letn. 2 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 2026-06-01 2026-06-11 61 281594371 10. 1007/ s10453- 026- 09924-x 0393-5965 RAZ_Markovic_Rene_2026.pdf RAZ_Markovic_Rene_2026.pdf 1 7DEE2CDC10417ED8BDA05BF7B91577BB a2e4c1ed38f965d3603b8bc7b4f49d17999afb45c8e3541356e1b2102f8b855d 5140c105-ad16-11f1-b668-00155d0001be https://dk.um.si/Dokument.php?lang=slv&id=212101 https://link.springer.com/article/10.1007/s10453-026-09924-x 1 87a723ae-6a08-11f1-87c9-00155d580e34 https://dk.um.si/Dokument.php?lang=slv&id=207209 Fakulteta za naravoslovje in matematiko Fakulteta za elektrotehniko, računalništvo in informatiko Medicinska fakulteta 0 0 0
