Description
Marques and co-authors study how city life shapes fire salamanders in a 2026 paper from Porto, Portugal. Urban land brings sealed surfaces, drier soil, and less plant cover, which reshape the small creatures salamanders eat. The team asked whether diet and snout shape change along a gradient from green to built-up sites.
They read diet from DNA in droppings and measured snout shape from photos with geometric methods. Overall diet diversity did not fall with urbanization, but woodlice became more common prey in city sites. Snout shape linked to diet diversity, and both diet and shape grew more alike among urban sites. The pattern fits a broader trend of city wildlife becoming more uniform.
