Event description


From hot toddies to corpse mimics – how and why some plants generate heat.

An illustrated talk by scientist Kirsten Bomblies and tour of our rare botanical books. We will talk about how – and why - some plants have evolved to be able to generate heat, just like we do. Thermogenesis is a rare adaptation in plants but has arisen multiple times. It allows some species to punch through thick winter snows, others to give bees a place to snuggle up in cold weather or to volatilize compounds that mimic unpleasant things like rotting flesh and dung to attract fly pollinators. We will use images from JIC’s historical collections and discuss some of the early descriptions of these remarkable plants as well as what we know now about their biology today, along with the surprising finding that there are two ways in which plants heat themselves, one of which is the same as humans.

Allow up to 2 hours.

There are 22 steps to climb to reach the Rare Books Room. Wheelchair access must be pre-booked.
