城市化加剧了全球城市的生物入侵

Biological invasions are a leading challenge to global sustainability and drive decreases in biodiversity, economic losses and disease transmission. As centers of international trade and human movement, cities are consistently recognized as invasion hotspots. However, drivers of urban biological invasions remain poorly understood, preventing effective management for sustainability. Here, on the basis of data from 436 non-native terrestrial vertebrates established in 1,029 cities worldwide, we found that hotspots of urban biological invasions were located mainly in developed countries, especially island cities, whereas the major native ranges of the non-native species were from developing countries. After accounting for urban areas and sampling efforts, we found that in addition to anthropogenic propagule pressure, more non-native species tended to occur in cities with greater urbanization, as indicated by higher habitat modification, warmer temperatures and lower native biodiversity. These findings highlight the importance of reducing anthropogenic disturbance to natural habitats, conserving native species and strengthen quarantine to control sustained invasions in global cities. Urbanization significantly influences biological invasions, with developed cities exhibiting higher non-native vertebrate richness. Key factors include propagule pressure, habitat modification and climate, emphasizing the need for targeted management strategies to mitigate invasions and enhance urban sustainability.
