Evolution in an Urbanizing World
The weather on the northern hemisphere is getting warmer which means beach days are approaching. Every beach dweller can confirm that seagulls (Larus sp.) can be very cunning and cheeky in order to steal food. Is this their ancestral behaviour or has this evolved with the rising of urban areas? Pavlova and Wronski (2020) studied... Continue Reading →
In response to human impact on the environment—from increased light, sound, air, and water pollution, to higher levels of interaction with humans—organisms must adapt to novel conditions in order to survive. One area in which organisms adapt is behavior. von Merton et. al. (2022) explores how the behavior and personality of two shrew species (Crocidura... Continue Reading →
An outstanding question in urban evolutionary biology is what factors influence a species' success in urban environments. This is a topic we've talked about before (check out Urban Adaptation in Mammals) and several other recent papers have tackled this topic. A variety of factors may influence whether or not a species occupies an urban environment... Continue Reading →
Urbanization has repeatedly been shown to negatively impact wild animals and is a particular concern for wild birds. Fortunately, some species are able to flexibly alter their behavioral phenotypes and adapt to the busy life in the city. Resource competition may be higher in urban environments, thereby selecting for more aggressive behaviors in city-slicking birds.... Continue Reading →
