The fate and function of marine megafauna

Junio 11, 2021

Large marine animals generally have unique functions for the ecosystem. They are also more susceptible to extinction when their habitats are altered. Around 3 million years ago, at least one third of the marine megafauna became extinct, possibly due to sea level fluctuations and the contraction of coastal habitats. This also led to a loss of some of their ecological functions. In the current era, many large marine animals are deemed at risk of extinction. What will be the consequences of this potential loss?

What the leaves tell us: stories of extinction and the origins of tropical forests

Abril 26, 2022

Plant leaves show us the species that exist in a forest, and the ecological conditions in which they live. These attributes can also be observed in fossil leaves, which allows us to reconstruct forests that existed millions of years ago and understand how they have changed over time. In this talk we will talk about how fossil leaves tell us about the effect of a mass extinction 66 million years ago, on the evolution of modern tropical forests.
