* Ecosystem dynamics: Feral species can outcompete native species for resources like food, water, and shelter, leading to a decline in native populations and even extinction.
* Food webs: Introducing a new predator or competitor can disrupt established food webs, causing cascading effects throughout the ecosystem.
* Habitat structure: Feral species can alter habitats through grazing, digging, or invasive growth, leading to changes in plant communities and overall landscape structure.
* Disease transmission: Feral species can carry diseases that can be transmitted to native species, causing outbreaks and impacting populations.
* Genetic diversity: Feral species can interbreed with native species, leading to genetic pollution and loss of genetic diversity.
Overall, the introduction of feral species disrupts the complex web of interactions that maintain a healthy ecosystem. This can result in biodiversity loss, ecosystem instability, and ultimately, a less resilient and productive environment.
