L. A. Mountain Lions Adapt to City Life by Going Nocturnal

In the heart of Los Angeles, mountain lions are shifting their schedules to avoid people. A new study found that these big cats, like the famous P-22, are becoming more active at night to steer clear of hikers, bikers, and other recreation enthusiasts. While this strategy helps them coexist with humans, it might come with a cost. Less daytime activity means less time for crucial tasks like hunting. Plus, it adds to the stress of living in an urban environment with traffic and poison risks. The study, which tracked 22 mountain lions using GPS collars, showed that females tend to be less nocturnal than males, possibly to avoid threats. Researchers were surprised to find that the lions didn't become immune to human activity over time. Instead, they adapted their behavior to avoid us, which is a positive sign for their ability to thrive in the city. However, there are trade-offs. Changing their hunting patterns can be energy-intensive and limit their options. Experts suggest that we should also do our part by minimizing challenges, like creating wildlife crossings to help them move safely. As we face a biodiversity crisis, it's crucial to consider how our recreational activities impact these animals.
