Lionfish are native to the tropical waters of the indo-pacific. what conclusions can be made about the impact of climate change on the range of lionfish and, therefore, on biodiversity? as ocean temperatures have increased, the range of the lionfish has changed. as top predator, it has little competition for eating smaller fish. this reduces biodiversity. global warming has forced the lionfish to warmer waters where it is able to mate with the native fish to produce hybrids. this increases biodiversity. climate change has restricted the habitat of lionfish. it has become an endangered species, reducing biodiversity. lionfish thrive in high carbon dioxide environments. they produce more offspring, which can then eat all of the native species in the area. this reduces biodiversity.
