What is an example of an invasive species effect?

The presence of invasive species can significantly disrupt local ecosystems, and strong competition with native species for resources is one of the most common and impactful effects. Invasive species often have traits that allow them to thrive in new environments, such as rapid growth, high reproductive rates, and adaptability to various conditions. These characteristics enable them to outcompete native species for essential resources like food, water, sunlight, and space.

When an invasive species establishes itself, it can lead to a decline in native populations, as the latter often cannot compete effectively. This can result in reduced biodiversity, altered community dynamics, and even the local extinction of less competitive native species. By monopolizing resources, invasive species can change the structure of the ecosystem and indirectly affect other organisms that depend on the native species, leading to broader ecological consequences.

In contrast, enhancing native species diversity, improving ecosystem services, and creating new unique habitats are generally associated with positive changes in ecosystems, which do not reflect the typical consequences of invasive species.
