Invasive species, introduced through centuries of human colonization, now threaten Galapagos ecosystems by outcompeting and displacing native species and reshaping the archipelago’s unique biodiversity. Invasive plants often show greater adaptability and aggressiveness than their endemic counterparts or direct competitors, while non-native animals thrive in disturbed habitats, competing with and hybridizing with endemic fauna. Human activities have facilitated the introduction and spread of these species, irreversibly altering the archipelago’s biodiversity. To protect this unique environment, urgent conservation efforts must involve local communities and implement effective tourism regulations to ensure the long-term preservation of the irreplaceable natural heritage of the Galapagos Islands.

摘要

Invasive species, introduced through centuries of human colonization, now threaten Galapagos ecosystems by outcompeting and displacing native species and reshaping the archipelago’s unique biodiversity. Invasive plants often show greater adaptability and aggressiveness than their endemic counterparts or direct competitors, while non-native animals thrive in disturbed habitats, competing with and hybridizing with endemic fauna. Human activities have facilitated the introduction and spread of these species, irreversibly altering the archipelago’s biodiversity. To protect this unique environment, urgent conservation efforts must involve local communities and implement effective tourism regulations to ensure the long-term preservation of the irreplaceable natural heritage of the Galapagos Islands.
