Human activity causing world’s mammals to become increasingly nocturnal
FORCED TO FLEE THE DAYLIGHT..
As the human population continues to grow, so does the requirement for mammal species to adapt their behaviours to survive. A recent study published in the journal Science explores the changes to the daily activity patterns of mammals in response to human activity. The global research project focused on 62 species larger than one kilogram across six continents. The team from the University of California at Berkeley found that, on average, these mammals increased their nighttime activity by 36% in response to human disturbance. This growing behavioural change could have many negative consequences. As mammals begin to shift to nocturnal patterns the fear is that these animals’ foraging or hunting behaviour will be disrupted, leaving them more vulnerable to predation and increased competition from other species.
