Contrary to our expectations, extinction selectivity based on
total calorific needs, which emphasises body size, did not differ between hyperthermals and other time intervals [images lightly adapted from Gavirneni et al. 2025, linked above]

Extinction selectivity against a high mass-specific metabolic rate was especially strong in the paleotropics during hyperthermal events

Whole body metabolic rate increased through time, consistent with increasing maximum body sizes and the postulated ramping up of ecosystem energetics. Mass-specific metabolic rate, the energy used per g tissue, however, decreased...

Why is what happened in an early #Jurassic warming crisis relevant today? Because our planet is now showing many of the same indicators as in these ancient crises, as we warm it by releasing the CO2 once captured by ancient plants (i.e. fossil fuels)

At +3°C warming, a region tended to lose 5% of its species while receiving 25% immigrating from elsewhere

Our study system was prehistoric, using #marine #fossils from the early Jurassic northwestern Tethys Sea during a warming-associated #extinction crisis, the #T-OAE. We modelled the climate with #ClimberX in agreement with geochemical indicators...

The more the region warmed, up to 10°C (mean=4.5°C), the stronger this relationship...

This one took some years in the making! Here, the closeness of a #jurassic species' temperature preference to its environmental temperature (=thermal bias) was a useful predictor of whether it moved in, remained, or moved out of a region, or went #extinct during #climatechange... rdcu.be/d8IfN
