What is often a direct result of invasive species introduced through ballast water?

The introduction of invasive species through ballast water can lead to significant alterations in local ecosystems. Invasive species often disrupt the balance of the existing flora and fauna, leading to competition for resources, predation on native species, and the potential extinction of indigenous populations. This change in species composition can impact food webs, local habitats, and overall biodiversity, ultimately altering the function and structure of the ecosystem.

Invasive species may also promote changes in nutrient cycling and affect physical environments, such as sediment composition and water quality. These ecological changes can have cascading effects, influencing various community interactions and ecosystem services, from which the original ecological stability may take a long time to recover, if it can recover at all. This highlights the critical importance of managing ballast water to prevent the introduction of harmful non-native species, thus preserving local ecosystems.
