How can invasive species affect biodiversity

Here are some ways invasive species impact native ecosystems:

Habitat modification.

Compete with native species for resources.

Predation of native species.

Herbivory on native plants.

Bring in pathogens.

Hybridize with natives, leading to loss of genetic diversity.

1) causing disease, (2) acting as predators or parasites, (3) acting as competitors, (4) altering habitat, or (5) hybridizing with local species.
