Mountain lions are lurking Greater Los Angeles in the evening to prevent human beings working out on their mountains, a brand-new research study discovers.
The human population of Greater Los Angeles is progressively utilizing mountain lion (Puma concolorarea for leisure activities such as hiking, running and biking. That puts the mountain lions in a difficult area– so they’re altering their habits.
Mountain lions, likewise called pumas or cougars, are naturally most active throughout sunset and dawn, however in locations where human beings participate in leisure activities, the felines now prefer nighttime hours, according to the research study, released Nov. 15 in the journal Biological Conservation
“This flexibility we see in mountain lion activity is what allows us to share these natural areas together,” research study lead author Ellie Bolasa doctoral prospect studying mountain lions and mule deer at the University of California, Davis, stated in a declaration “Mountain lions are doing the work so that coexistence can happen.”

Bolas and her associates fitted GPS collars to 22 mountain lions residing in and around the Santa Monica Mountains in between 2011 and 2018. They then compared mountain lions’ activity with human leisure activity signed up on the online platform Stravawhich allows users to track their workout.
The scientists discovered that mountain lions residing in locations with increased leisure activity moved the timing of their activities from dawn to night– when human activity was at its most affordable, according to the research study. This recommends they adjusted to prevent individuals.

These findings follow previous research studies that recommend mammals throughout the world are ending up being more nighttime in action to human activities, which predators like mountain lions will head out of their method to prevent people.
A 2019 research study released in the journal Ecology Letters discovered that the noise of people talking sufficed to frighten mountain lions and decrease their activity– to the point that our voices had a comparable result to getting rid of the predators from the community completely. Human beings have actually traditionally maltreated mountain lions, so this worry of our types is well-earned.
Today, mountain lions living around Los Angeles deal with lots of hazards, consisting of hectic roadways, wildfires, rodenticide direct exposure, low hereditary variety and fragmented environment, according to the declaration. The research study authors kept in mind that our leisure activities are another possible stress factor for the felines.
“Even something as innocuous as recreation can add to these other stressors we’re bringing into their lives, potentially by altering the amount of energy they have to expend for hunting and other needs,” Bolas stated. “But we can feel a sense of optimism that they are flexible in the timing of their activity. Coexistence is happening, and it’s in large part because of what mountain lions are doing.”
