invasion ecology

Invasion ecology is the study of how non-native species spread into new environments and impact local ecosystems. These invasive species often compete with native plants and animals for resources, sometimes outcompeting or displacing them. Their arrival can disrupt existing food webs, reduce biodiversity, and alter natural habitat functions. Researchers analyze the factors that enable invasions, such as human activity or environmental changes, to better manage or prevent harmful invasions. Overall, invasion ecology helps us understand and mitigate the ecological consequences of species that are introduced outside their natural ranges.
