Final answer:
Invasive species impact native endangered species through ecosystem modification, chain reactions, and multiple effects, often leading to altered habitats and extinction of native species.
Step-by-step explanation:
Of particular concern are invasive species that impact native endangered species via ecosystem modification, chain reactions, and multiple effects. Invasive species, often introduced through human actions, can out-compete or predate native species, effectively altering the ecological balance and sometimes leading to the extinction of native species. Examples of ecosystem modification include North American beavers in Tierra del Fuego transforming forests into meadows and Australian paperbark trees changing grasslands into monospecific forests in the Florida Everglades. Chain reactions are seen with the introduction of the Asian parasitic tapeworm affecting woundfin minnow populations, and the European rabbit population decline in Britain affecting the large blue butterfly due to habitat changes. Multiple effects can be observed with species like the round goby in the Great Lakes, which feeds on native species as well as on invasive zebra and quagga mussels.
