20.500.12556/RUP-23040 Species–park networks reflect the spatial structure of urban green infrastructure As cities expand, natural and semi-natural habitats are increasingly restricted in extent and connectivity, posing major challenges for biodiversity conservation. Urban parks, as nodes of green infrastructure, improve ecological connectivity in the urban landscape, yet their functional role in supporting urban plant communities remains challenging to quantify. This study aimed to investigate whether differences in the functional role of urban parks are reflected by their spatial location within the green infrastructure. We applied a bipartite species-park network approach to assess the role of urban parks in supporting plant species in three historic cities in north-eastern Italy. In 2024, we surveyed 57 parks, recorded vascular plant species in nested plots and measured park attributes including area, distance to the city centre, distance to other parks and tree canopy cover. Species–park networks were used to quantify the functional role of each park through park specialisation, importance, compositional representativeness, and colonisation potential. Statistical models showed that parks further from the city centre supported richer plant communities and hosted species more dependent on individual parks, while parks at intermediate distances from the centre acted as compositional links between parks closer and further from the city centre. Parks with greater tree canopy cover tended to host species that achieved comparatively higher local cover but showed reduced compositional representativeness to other parks. Our results revealed that the functional role of parks in supporting plant communities was strongly associated with their spatial location within the green infrastructure, providing insights for urban biodiversity conservation and landscape planning. Z širjenjem mest se obseg in povezanost naravnih ter polnaravnih habitatov vse bolj omejuje, kar predstavlja velike izzive za ohranjanje biotske raznovrstnosti. Mestni parki kot vozlišča zelene infrastrukture izboljšujejo ekološko povezljivost v urbani krajini, vendar je njihova funkcionalna vloga pri podpori urbanih rastlinskih združb še vedno težko kvantificirati. Namen te študije je bil raziskati, ali se razlike v funkcionalni vlogi urbanih parkov odražajo v njihovi prostorski lokaciji znotraj zelene infrastrukture. Za oceno vloge urbanih parkov pri podpori rastlinskih vrst v treh zgodovinskih mestih severovzhodne Italije smo uporabili bipartitni pristop mreže vrst in parkov. Leta 2024 smo pregledali 57 parkov, zabeležili vrste vaskularne flore v gnezdenih ploskvah ter izmerili atribute parkov, vključno s površino, oddaljenostjo od središča mesta, oddaljenostjo od drugih parkov in pokrovnostjo krošenj dreves. Mreže vrst in parkov smo uporabili za kvantificiranje funkcionalne vloge vsakega parka prek specializacije parkov, pomena, kompozicijske reprezentativnosti in kolonizacijskega potenciala. Statistični modeli so pokazali, da so parki, ki so bolj oddaljeni od mestnega središča, podpirali bogatejše rastlinske združbe in gostili vrste, ki so bile bolj odvisne od posameznih parkov, medtem ko so parki na vmesnih razdaljah od središča delovali kot kompozicijske povezave med parki, ki so bili bližje ali dlje od mestnega središča. Parki z večjo pokrovnostjo drevesnih krošenj so običajno gostili vrste, ki so dosegle sorazmerno večjo lokalno pokrovnost, vendar so pokazale manjšo kompozicijsko reprezentativnost v primerjavi z drugimi parki. Naši rezultati so pokazali, da je bila funkcionalna vloga parkov pri podpori rastlinskih združb močno povezana z njihovo prostorsko lokacijo znotraj zelene infrastrukture, kar zagotavlja vpogled v ohranjanje urbane biotske raznovrstnosti in načrtovanje krajine. bipartite network green infrastructure habitat connectivity urban biodiversity urban park bipartitne mreže zelena infrastruktura povezljivost habitatov urbana biotska pestrost urbani park true false true Angleški jezik Slovenski jezik Članek v reviji 2026-05-11 13:41:30 2026-05-11 13:41:34 2026-05-12 03:07:41 0000-00-00 00:00:00 2026 0 0 str. 1-12 iss. 3, article 142 Vol. 29 Jun. 2026 0000-00-00 Zaloznikova NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2026-05-08 574.1 1083-8155 10.1007/s11252-026-02000-9 277727491 RAZ_Fantinato_Edy_2026.pdf RAZ_Fantinato_Edy_2026.pdf 1 2EE00512CF686E63050ABC7A558861BE f46f929c8beb1e0bc976bc3778de7ddf6682597e0be445d84945b719239bc7b5 6c916e5b-4d2e-11f1-9e8d-005056ac49c0 https://repozitorij.upr.si/Dokument.php?lang=slv&id=33661 https://link.springer.com/article/10.1007/s11252-026-02000-9?utm_source=rct_congratemailt&utm_medium=email&utm_campaign=oa_20260508&utm_content=10.1007%2Fs11252-026-02000-9 0 41b8b38d-4d2f-11f1-9e8d-005056ac49c0 https://repozitorij.upr.si/Dokument.php?lang=slv&id=33662 Fakulteta za matematiko, naravoslovje in informacijske tehnologije 0 0 0
