The mix of urban birds, bugs and other critters that humans have grown familiar with is due for a big shift because of climate change, a new study says.

91裸聊视频淭he nature that people interact with isn91裸聊视频檛 what91裸聊视频檚 in Banff or some provincial park,91裸聊视频� said Alessandro Filazzola, lead author of a paper published Wednesday in the journal PLOS One. 91裸聊视频淚t91裸聊视频檚 in their backyard.

91裸聊视频淐ities don91裸聊视频檛 move. If you91裸聊视频檙e staying still while the world is moving around you, what91裸聊视频檚 going to happen to all the wildlife that you91裸聊视频檙e familiar with?91裸聊视频�

To answer that, Filazzola, from the University of Toronto91裸聊视频檚 Centre for Urban Environments, conducted a simulation combining eight different climate models with an enormous data set that detailed sightings of 2,019 different species from 60 cities around North America.

That combination allowed him and his colleagues to estimate how common each animal is in its current environment, how widely it91裸聊视频檚 distributed and how climate changes such as temperature and precipitation could affect its future.

On the one hand, cities with temperate climates such as those in Canada could welcome new animals.

By the end of the century, cities such as Ottawa and Edmonton could become hospitable for hundreds of new species while losing habitat for a couple dozen.

Quebec City is the champion. Filazzola91裸聊视频檚 simulation suggests the Quebec capital could support more than 500 new species.

91裸聊视频淲hen we get these slightly warmer temperatures and changes in precipitation patterns, a lot more species are coming in than they are leaving,91裸聊视频� he said.

On the other hand, the animals most likely to take advantage are the ones already widespread. Local specialists are likely to lose out.

91裸聊视频淚f a species is widely distributed, like raccoons, the likelihood of climate change making them leave a city is really low. It91裸聊视频檚 in the localized species 91裸聊视频� the ones you only see in a couple cities 91裸聊视频� that you see the change.91裸聊视频�

And many of those new arrivals are likely to be insects. Varieties of centipedes, butterflies, spiders and cockroaches are all likely to pop up in places they91裸聊视频檝e never been before, Filazzola suggests.

Songbird distribution is likely to drop. Foxes, too. But if you like pelicans, you may be in for a treat. Same with various kinds of lizards.

The cities most likely to be net losers of species, the study suggests, tend to be in the southeast United States. Atlanta is set to suffer the most.

Filazzola cautions that the projections in his study won91裸聊视频檛 necessarily come to pass. Climate isn91裸聊视频檛 the only factor that influences where a species is able to live.

91裸聊视频淭here91裸聊视频檚 lots of reasons why or why not a species would live in a city. There could be no food when it gets there, there could be a predator that eats it.91裸聊视频�

But change is coming, he says, and not just to the large landscapes we tend to think of when we talk about nature.

91裸聊视频淲e take for granted what91裸聊视频檚 going on in our backyard. But there91裸聊视频檚 a lot going on there other than a few common species.91裸聊视频�

The wholesale shift that could be on its way has implications for pest control and other services that rely on the environment. And it could change how we feel about our own habitat.

91裸聊视频淚magine hearing different birds in the morning when you go out to have your coffee,91裸聊视频� Filazzola said. 91裸聊视频淚t means a lot.91裸聊视频�
