How do AIS affect biodiversity in aquatic ecosystems?

Aquatic invasive species (AIS) significantly impact biodiversity by often outcompeting native species for crucial resources like food, sunlight, and space. When AIS are introduced to a new ecosystem, they can thrive due to the absence of natural predators, diseases, or competitive species that normally regulate their populations. As these invaders gain a foothold, they can proliferate rapidly, altering the structure and function of the ecosystem.

The dominance of AIS might lead to a drastic decrease in native species, as they struggle to compete effectively. This competition can result in diminished populations of local flora and fauna, ultimately leading to a loss of biodiversity. The reduction in native species not only affects the ecosystem itself but also impacts the services it provides, such as water purification, habitat stability, and fishery productivity. Therefore, understanding the role of AIS in outcompeting native species is crucial for conservation efforts and maintaining the health of aquatic ecosystems.
