good morning. I strongly suspect that we don't really know (or agree) what geographic ranges are, and therefore, our estimates of how species' ranges are shifting in the Anthropocene are uninterpretable. I wrote something about this: doi.org/10.1111/2041... and I'll share the main findings...

Measuring the edges of species' geographic ranges

The fundamental unit of spatial ecology is a species range: the geographical area that it occupies. Species ranges are delineated by range edges (also known as boundaries or limits). Why range edg...

Ever wonder why high latitude ectotherms don’t consistently evolve greater thermal plasticity than those in the tropics? @ggcostoya.bsky.social, Mike Logan and I have an idea why, and we explore it in this theoretical analysis www.biorxiv.org/content/10.6...

Climate variability and the paradox of plasticity

Adaptive phenotypic plasticity is expected to evolve when environmental conditions change predictably over time. This has led to the hypothesis that ectotherms in environments with low temperature sea...

Enjoyed working with @veritasium.bsky.social on this video on scaling and the hidden math that governs life. A nice introduction to the pervasivness of scaling in biology and an introduction to #MetabolicScalingTheory youtu.be/tL9Lw250spc?... 🧪🌾🌐

Congratulation to @jameststroud.bsky.social on winning our Bicentenary Award 2026! An exceptional evolutionary ecologist with 61 papers and 3,000+ citations, his 2025 paper in Nature caps a decade of landmark lizard evolution work. His outreach programme Lizards on the Loose has engaged thousands!

I'm very happy to announce that I will be joining @jameststroud.bsky.social's lab at @gtsciences.bsky.social this June as a Postdoc Fellow! Super excited to join the 'zard hunt on "lizard island" and for all the excited research ahead! #anoletime 🦎

Thrilled to share that my first dissertation chapter is now published at Ecology! dx.doi.org/10.1002/ecy.... We embed TPCs into population dynamics to show how changing temperatures' ordering — not just its distribution — increases extinction risk (i.e. heatwaves matter!) @esajournals.bsky.social

Figure demonstrating how the ordering of temperatures through time determines whether an ectothermic population experiencing those temperatures will go extinct

Why has live birth evolved repeatedly in lizards? A mechanistic model linking behavior, thermal physiology, and life history shows cold climates favor viviparity, providing causal support for the classic cold-climate hypothesis. Image credit: Wikimedia academic.oup.com/evlett/advan...

Check our new paper in @evolletters.bsky.social "Live birth in lizards: A process-based model for the roles of temperature, behavior, and life-history" In this study, we develop and validate a model capable of accurately predicting gestation length in lizards! academic.oup.com/evlett/advan...

Accurate quantification of thermal environments is vital for predicting climate change impacts. Here is a new method, integrating aerial thermography with field-deployed operative temperature models to generate fine-scale, spatiotemporally complete maps of operative temperature 🗺️ 🌡️ buff.ly/vngpJqN

The late Eric Pianka made thousands of observations of desert lizard body temperature and activity. We used them to test biophysical models of their cost of living and projected the models to past and future climates in Africa and Australia #unimelb #ARC @science.org www.science.org/doi/10.1126/...

What a cool paper! 🤩 Using @inaturalist.bsky.social observations, Mayer et al. found that there are more melanistic snakes in colder regions than in warmer ones AND that melanistic snakes are more abundant with ⬆️ avian predator density 🐍🐦 Have look at it here: doi.org/10.1111/jbi....
