The ever-increasing and expanding globalisation of trade and transport underpins the escalating global problem of biological invasions. Developing biosecurity infrastructures is crucial to anticipate and prevent the transport and introduction of invasive alien species. Still, robust and defensible forecasts of potential invaders are rare, especially for species without known invasion history.

- The IPBES invasive alien species assessment is the first comprehensive global review focusing on the threats posed by invasive species to biodiversity and human wellbeing, synthesizing over 13,000 scientific and local knowledge sources.
- It reveals significant and escalating threats from invasive alien species and outlines practical management strategies for addressing these challenges.
- The assessment has garnered support from 143 member states, urging immediate action against biological invasions to protect ecosystems and communities worldwide.
Invasive Aedes aegypti and Aedes albopictus mosquitoes transmit viruses such as dengue, chikungunya and Zika, posing a huge public health burden as well as having a less well understood economic impact. We present a comprehensive, global-scale synthesis of studies reporting these economic costs, spanning 166 countries and territories over 45 years. The minimum cumulative reported cost estimate expressed in 2022 US$ was 94.

- - Biological invasions are a big problem for ecosystems and economies, and Türkiye is especially at risk due to its trade connections and location between Europe and Asia.
- - Researchers analyzed the economic costs of invasive species in Türkiye and found it added up to about $4.1 billion from 1960 to 2022, mostly affecting agriculture and fisheries.
- - The yearly costs of these invasive species are increasing and could reach $504 million a year soon, highlighting the need for better tracking of these costs and better management strategies to deal with them.
Urbanization is an important driver of global change associated with a set of environmental modifications that affect the introduction and distribution of invasive non-native species (species with populations transported by humans beyond their natural biogeographic range that established and are spreading in their introduced range; hereafter, invasive species). These species are recognized as a cause of large ecological and economic losses. Nevertheless, the economic impacts of these species in urban areas are still poorly understood.
