Biotic responses to past hyperthermal events
Convener: Wolfgang Kiessling | Co-conveners: Carl Reddin, Linda Ivany, Alex DunhillECSECS, Kenneth De Baets
The fossil record is rich in examples of climate changes leading to catastrophic responses of the biosphere. Species range shifts, ecosystem changes and collapses, and widespread extinctions were common responses to past intervals of rapid global warming, so-called hyperthermal events. The degree to which we can learn from the past to predict the future critically depends on the uniqueness of context and ecological response mechanism, and the scale-dependency of such events.
For example, while there seems to be a temperature threshold for hyperthermal mass extinctions, the importance of deoxygenation and acidification to large-scale biotic responses remains unclear.
We invite contributions that advance our understanding of large-scale biological responses to past hyperthermal events. This includes studies in paleobiology, eco-/physiology, climate and environmental forcing using proxy data, and meta-analyses.
