Warmer temperatures make invasive brown anoles more aggressive (English, Level A1)

Brown anoles are invasive lizards in some places.
Green anoles are native lizards that live nearby.
The two anoles compete for the same spaces.
Researchers watched pairs of the two species.
They used small enclosures with different temperatures.
Warmer temperatures made brown anoles more aggressive.
Green anoles also became a bit more aggressive.
The aggression gap grew when it got warmer.
