The first episode of my CBC Radio series "A Shore Thing" aired this week.

In this episode I talk all about sea urchins!

It also appears I have my own theme song now! A nice little jingle 😂

Little is known about the mechanisms controlling thermal acclimation in fish.

Check out this study exploring possible roles of hormones & skin thermoreception during acclimation in goldsinny wrasse.
