Abstract

Progresivna urbanizacija i prostorno širenje gradova rezultiraju degradacijom prirodnih staništa, čime se
značajno ugrožava bioraznolikost unutar urbanih ekosustava. Gradski parkovi imaju važnu ulogu u
očuvanju bioraznolikosti unutar urbanih područja, jer osiguravaju mikroklimatske uvjete i resurse
neophodne za opstanak mnogih organizama, uključujući beskralježnjake tla. Ciljevi ovog rada su: istražiti
utjecaj glavnih okolišnih čimbenika (temperature i fizikalno-kemijskih svojstava tla) na... More strukturu zajednica
beskralježnjaka tla; analizirati njihove zajednice na različitim udaljenostima od pješačkih koridora;
usporediti zastupljenost porodica s parametrima sintakse prostora koji ukazuju na stupanj urbanizacije; te procijeniti njihovu upotrebu kao indikatora antropogenog utjecaja na urbane ekosustave. Uzorkovanje je provedeno na po dvije postaje u gradskim parkovima Maksimir i Jarun pomoću Barbierovih lovnih posuda. Na svakoj od postaja odabrana su po tri mikrostaništa na različitim udaljenostima od glavnih koridora (aleja). Prikupljeni uzorci tla analizirani su radi utvrđivanja okolišnih parametara, dok je sintaksa prostora korištena za procjenu prostorne povezanosti i integracije parkova. Rezultati su pokazali da svojstva staništa (temperatura, kiselost i udio humusa u tlu) značajno utječu na zajednice beskralježnjaka, s većom brojnošću na mikrostaništima udaljenijim od glavnih koridora. Parametri sintakse prostora korelirali su s brojnošću organizama različitih porodica, potvrđujući potencijal mjera raznolikosti beskralješnjaka tla i sintakse prostora kao učinkovitih pokazatelja antropogenog utjecaja u gradskim parkovima.

Abstract (english)

Progressive urbanization and spatial expansion of cities result in the degradation of natural habitats, significantly threatening biodiversity within urban ecosystems. Urban parks play an important role in preserving biodiversity within urban areas, as they provide microclimatic conditions and resources essential for the survival of many organisms, including soil invertebrates. The objectives of this study are to: investigate the impact of key environmental factors (temperature and... More physico-chemical properties of the soil) on the structure of soil invertebrate communities; analyze communities at different distances from pedestrian corridors; compare the representation of invertebrate families with space syntax parameters indicating the degree of urbanization; and assess their use as indicators of anthropogenic impacts on urban ecosystems. Sampling was conducted at two sites in each of the city parks – Maksimir and Jarun – using Barber pitfall traps. At each site, three microhabitats at different distances from the main corridors (allée) were sampled. Collected soil samples were analyzed to determine environmental parameters, while space syntax was used to assess the spatial connectivity and integration of the parks. The results showed that habitat properties (soil temperature, acidity and humus content) significantly influence invertebrate communities, with greater abundance observed in microhabitats more distant from the main corridors. Space syntax parameters showed a correlation with the abundance of organisms from various families, highlighting the potential of soil invertebrate diversity and spatial syntax metrics as effective indicators of anthropogenic
impact in urban parks. Less
