I'll have more info in a few weeks when I get back from fieldwork but I'll be recruiting 2 graduate students to begin in 2026 (1 PhD, 1 MS). My lab investigates macroevolutionary dynamics using phylogenetic methods & the fossil record. Please share with students having strong research interests!

South-North cross section through the eastern tropical Pacific oxygen minimum zone. It shows the north and south lobe of the oxygen minimum zone, separated by the equatorial undercurrent. The Peru-Chile current and California Current ventilate the near-surface waters, North Pacific Intermediate waters bring low-oxygen waters to the northern lobe at ~550m, and Antarctic Intermediate Waters ventilate the southern lobe at the same depth. The oxygen minimum zone is fueled by Ekman upwelling and remineralization of sinking organic material.

In this paper, we present new global calibrations for the I/Ca proxy for ocean oxygenation, with the first Pacific transect. By comparing data from planktonic foram species that live at different water depths, we gain a better understanding of the proxy and its relationship to O2

Share of common mammalian species across continents

Ecological characteristics of species with different degrees of geodispersal.

Cool study. Shows low dispersal of mammals across continents. Most are continental scale endemics. Significant in understanding the modern structure of the Bretskyan hierarchy from mammalian perspective.

a, Global average temperature and the timing of large igneous province (LIP). Modified from ref. 108. b, Palaeo-ocean acidification events during the Mesozoic and Cenozoic. Solid red lines represent confirmed ocean acidification events. Dashed orange lines represent disputed ocean acidification events. c, Morphological simplification in brachiopods and foraminifera reduces the increased calcification energy caused by ocean acidification across the PTME and T-OAE in this study. AOAE, Aptian oceanic anoxic event; CALIP, Central Atlantic LIP; COAE, Cenomanian oceanic anoxic event; DLIP, Deccan LIP; KFLIP, Karoo-Ferrar LIP; KPgME, Cretaceous–Palaeogene mass extinction; NALIP, North Atlantic LIP; N-MLIP, Naturaliste-Madagascar LIP; PETM, Paleocene-Eocene Thermal Maximum; STLIP, Siberian Traps LIP; TJME, Triassic–Jurassic mass extinction.

Around extinction events, the shape of shells of certain groups becomes simpler. It's a sort of austerity measure to reduce the energy cost associated with producing a shell. Might be something we need to keep an eye out for in marine organisms now. 🧪🌊

We've had a Very Important Ice delivery!

These precious ancient ice core samples from Antarctica are expected to reveal a climate record stretching back more than 1.5 million years 🤯

That's further than we've ever looked back before.

one very localised one from the region I grew up in on the south coast is "were you born in Yapton?" which apparently stems from the fact people from Yapton would leave their doors unlocked to allow smugglers to hide from the law

Figure from the paper showing our model results when considering the tropical vegetaiton collapse - a long-high temperature period following the PTME

Great to see this finally out today! We show that the collapse of tropical vegetation during the Permo-Triassic extinction is a key driver of the long-term super-greenhouse climate that followed it.

Pleased to say that the final chapter of my PhD is out today in Nature Ecology and Evolution: www.nature.com/articles/s41...
My favourite bit of science that I've done to date. If you enjoy biogeography, weird reptiles, and the TARDIS, then have a read!

A major highlight is that regional data picks up nuances between ocean basins that is lost/homogenized using a global approach!

More data at higher spatial and temporal resolution is needed to disentangle the subtleties in biodiversity responses to Earth system dynamics (2/2)

We show that planktonic foraminiferal communities show very high regional heterogeneity in response to the palaeoceanographic changes associated with the Plio-Pleistocene.
