Biological invasions pose a rapidly expanding threat to the persistence, functioning, and service provisioning of ecosystems globally, and to socio-economic interests. The stages of successful invasions progress driven by the same mechanism that underlies adaptive changes across species in general—via natural selection on intraspecific variation in...

Biological invasions are increasingly recognised as a major global change that erodes ecosystems, societal well-being, and economies. However, comprehensive analyses of their economic ramifications are missing for most national economies, despite rapidly escalating costs globally. Türkiye is highly vulnerable to biological invasions owing to its ex...
