Research involving 62 species found mammals spent relatively less time being active during the day when humans were nearby
Human disturbance is turning mammals into night owls, with species becoming more nocturnal when people are around, research has revealed.
The study, encompassing 62 species from around the globe, found that when humans were nearby, mammals spent relatively less time being active during the day and were more active at night - even among those already classed as nocturnal.
Experts say such a shift might not only affect particular animals themselves for example impacting their ability to navigate or find food but also have numerous knock-on effects across other species.
Kaitlyn Gaynor, first author of the research and a doctoral student at the University of Berkeley, said the findings echoed the past, noting it was only after the extinction of the dinosaurs that mammals started exploring the daylight.
Humans are now this ubiquitous terrifying force on the planet and we are driving all the other mammals back into the night-time, she said.
Gaynor said the shift might affect numerous interactions between species, noting that coyotes in California are moving from eating diurnal creatures like squirrels and birds to nocturnal animals like mice, rats and rabbits, while sable antelope in Zimbabwe are less able to access water during the day as they shift towards increased nocturnal behaviour.
Dr Chris Carbone from the Institute of Zoology at the Zoological Society of London, who was not involved in the research, said it was startling to see that the trend is so widespread.

Toddlers made my mammals go nocturnal
Don’t drive at night
Humans may be “terrifying” but we are just as natural as any other animal and everything we do is natural, just like every other animal. Everything we use and make comes from the earth and so is also natural, even so-called synthetics.
Every animal, insect and plant living on this planet spends its time doing the same thing: Attempting to expand its habitat area at the expense of every other living thing on earth. It’s natural.
If we cut immigration to say 200,000 per year allowed, send home all the illegals, this country would be close to the 250 million people instead of 300+ Million. Why do we want to be crowded? Who does this benefit? We all know, the businesses that want cheap labor, and the cities who want to cram everyone into small apartments so they don’t lose a single cent of the tax revenues that used to be paid to NO ONE, because in the Counties, much happens without money changing hands.
No it’s not human’s fault. It’s vampirism is spreading in the animal kingdom. They just can’t stand the daylight once infected.
Not that you have a bad idea but we’d still be crowded.
There is plenty of habitable land today for people to live on uncrowded even at this population level. Most of us choose to live on top of each other in cities, leaving the rest of the country uncrowded.
Human disturbance is turning mammals into night owlsTheyre evolving into owls due to humans? Is that natural?
Mine get so rowdy sometimes, my birds cage themselves. Right now they’re quiet so they’re making their rounds.
That won't save you...
Scientist believe in evolution.....
But not during their lifetime.( Man’s fault!)
When the word “study” and “research” is part of the title of something, no matter what is your opinion on a subject, it requires great investigation of the particular study, or piece of research.
Of the “peer reviewed” studies and research papers reported in reputable scientific and academic journals today in the U.S., a majority of them that others have sought to compare, use or cite, give conclusions/results that those others find they cannot independently reproduce. When a research or study is merely self-referential and has conclusions that cannot be duplicated by inpendent research, the research methodology & the conclusions are suspect.
That is the state of most “studyies” reported out of academia today. Singular conclusions that other studies find, or will find, cannot be reproduced.
They use to call “junk science” so much of what passes for science today.
In other words, the majority of peer reviewed studies and reseach do not stand up to indpendent scrutiny.
“Humans are now this ubiquitous terrifying force on the planet and we are driving all the other mammals back into the night-time,” Kaitlyn Gaynor, doctoral student at Beserkley said.
This planet would be so wonderful without humans. Animals would be in paradise. The lion would lay down with the lamb.
The hypothesis is written before the study so the study has to reflect the hypothesis. Junk science 101.
WTF, they didn’t blame “climate change”?!
As the kids got taller the cats went higher. Then the kids started climbing. Poor cats had to start hiding in dark places during the day.
Its not junk science around where I live the mammals have figured out how to avoid being placed next to my gravy and mashed potatoes.
Are you sure it isn’t global warming? Everything else is blamed on it!!
