‘We’re All Asgardians’ a talk on the origins of Eukaryotes (us) with implications for our present-day immune systems by Brett Baker, University of Texas, Austin. Dr. Baker inaugurated the EPS Wares Distinguished Public Lecture series.

Eukaryotic cells are most closely related to the 'Hod' branch of the Asgard branch of the Archaea.

A family tree of Bacteria, Archea, the Asgard branch of Archea containing the branches that gave rise to Eukaryotic cells.

Congratulations to Dr. Pascale Daoust, who successfully defended, "Ocean Acidification: Insights from the Behaviour of Ancient and Modern Carbonates", supervised by Al Mucci and Galen Halverson.

The work involved field and laboratory studies of the Paleocene-Eocene Thermal Maximum section near Campo, Spain.

The figure shows the depositional environments at the time; from Daoust et al, submitted, modified from Pujalte et al. (2014)

An amazing talk by Max Lloyd of Penn State University. He used clumped isotopes to separate the effects of CO2 abundance, water availability, and temperature on plant stress. The plot shows the clumped signal in lignin from recent trees but he has analyzed samples from the last glacial maximum. An implication is that even in a high-CO2 world, water and heat stress reduce the ability of plants to produce biomass.

Plots showing the effect of growing season temperature and atmospheric CO2 concentration (greenhouse and natural) on a particular clumped isotope signal in the tree's lignin. This and similar data, combined with modelling, allows the measured clumped isotopes to constrain plant stress and biomass production.

A very productive hour spent learning about Earth's primary productivity (organic molecules produced) over time via a talk by Peter Crockford, Carleton University.

Fun fact: every carbon atom has likely be cycled through an organism ~100 times over the last 3+ billion years!

Crockford et al., The geologic history of primary productivity, Current Biology (2023), doi.org/10.1016/ j.cub.2023.09.040

Figure 1 from Crockford et al, 2013. It shows estimates of primary productivity over time, along with the dominant type of organisms contributing to the production of organic molecules.
