An amazing couple of days at the 12th International Conference of Poeciliid and Goodeid Biologists (PoGoBio2026) in Padova, Italy, last week with my MSc and PhD students, who did an excellent job at presenting their research.

Excited to share our new paper, led by Brazilian collaborators, on male coloration of guppies in response to urban pollution: www.sciencedirect.com/science/arti... @rhulbiology.bsky.social
This is a graphical abstract, showing that male nuptial color changes with increasing pollution. Guppies in more polluted waters develop more intense white ornaments and increase the number and body area covered by violet color ornaments.
