Which advantages can allow an introduced species to become invasive?

An introduced species becomes invasive when it possesses specific advantages that allow it to thrive in a new environment where it would otherwise struggle to survive. Key factors contributing to this success include:

• Competitive Advantage: Invasive species often possess built-in competitive traits that allow them to outperform indigenous species for essential resources like food and living space.1
• Lack of Natural Predators: A new habitat may lack the natural predators or biological controls that would normally keep the population of the introduced species in check.1
• Environmental Adaptability: Some species are highly adept at adjusting to new surroundings, allowing them to establish stable breeding populations where others fail.1
• Climate Change: Shifts in global climate, such as rising atmospheric carbon dioxide concentrations and warming temperatures, can provide new opportunities for invasive species to expand into habitats that were previously inhospitable to them.2

By exploiting these advantages, invasive species can significantly disrupt ecosystems, leading to a reduction in biodiversity and the potential extinction of native organisms.1
