Study Finds Turtles, Mice, and Scorpions Likely to Increase in US Cities Due to Climate Change
A recent study published in PLOS ONE has revealed that climate change is driving animals, including mammals and insects, to migrate to urban areas across the US and Canada, altering their traditional habitats.
This research highlights how species such as peregrine falcons, coyotes, and cabbage white butterflies are becoming more common in city environments, pressured by climate changes.
The study examined data from 60 populous cities, utilizing climate projections and biodiversity data from community science networks. According to lead researcher Alessandro Filazzola, urban wildlife populations are expected to change significantly in the coming years, influenced by varying degrees of global warming.
Key findings include a predicted decrease in the prevalence of vertebrates like loons and amphibians, along with the common earthworm, as cities warm. Conversely, turtles, scorpions, and mice populations are anticipated to rise.
The study predicts that even with moderate warming, urban areas could see a notable turnover in species, with new kinds arriving and others leaving. Cities like Toronto and Quebec City may gain hundreds of new species by 2100, while others like Atlanta and San Antonio could experience more significant losses, including in tree species.
The study underscores the complexity of changing ecosystems and the challenges of adapting to new urban wildlife dynamics. While these shifts may lead to increased human-wildlife interactions, both positive and challenging, they also offer a reminder of the close ties between urban living and nature.
Researchers hope these insights prompt further examination into the ways climate change impacts urban biodiversity.
