The third Rewilding event at Trinity in association with @irishwildlifetrust.bsky.social during Autumn 2025.

In the final event, Professor @jcsvenning.bsky.social spoke, amongst other things, about the vital role of large herbivores in shaping natural ecosystems.

Sad news … we lost a visionary scientist. His work and writing changed my understanding of the rules of ecological systems and evolutionary history
I'm very sad to say William Bond, of the University of Cape Town & Fellow of the Royal Society (@royalsociety.org ), has passed away. It is a great loss. He was an enthusiastic ecologist and a critical thinker. I learned a lot, and I still had a lot to learn from him. RIP. 😢

Guest Helmut Hillebrand talks about tipping points and planetary boundaries.
