Live birth in lizards: A process-based model for the roles of temperature, behavior, and life-history
To mediate trade-offs between survival and fecundity, multiple groups have independently evolved live birth (viviparity), including 70 transitions in lizar

In this study, we develop and validate a model capable of accurately predicting gestation length in lizards!

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 🗺️ 🌡️

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

Climate change and the cost-of-living squeeze in desert lizards
Climate warming can induce a cost-of-living “squeeze” in ectotherms by increasing energetic expenditures while reducing foraging gains. We used biophysical models (validated by 2685 field observations...

How an infinite DNA glitch saved millions.
Our latest video is about Kary Mullis - quite possibly the weirdest person ever to win the Nobel Prize.

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....
