Climate change can change the breeding patterns of some animals. Breeding patterns refer to when and how animals reproduce, including how many young an animal has and how often. If breeding patterns change, an entire population may change or become extinct. The question the scientists in this study wanted to answer was how certain amphibian populations and their breeding patterns may be responding to climate change.
