How to measure the planet’s heartbeat Ecosystem scientist Yadvinder Malhi takes us on a jaw-dropping journey through the hidden flows of energy that make life on Earth tick. From sun-soaked forests to tropical islands, he shows how his te...

On a busy day I had a TED talk published. This talk is about the energy flows of the living world, and how we need to centre this vibrancy as a core value when thinking about working with nature for climate change and other challenges

A wide range of abiotic and biotic variables leaves most variation in bird nest architecture unexplained | Proceedings of the Royal Society B: Biological Sciences Nests are the locations or containers for offspring, and mediate interactions between offspring and the environment. However, understanding how environmental factors shape the evolution of nest archit...

New paper today in Proc B @royalsociety.org. We explored nest architecture in 3,685 species of birds, modelling the multivariate nature of nests, i.e. how shape, location or attachment co-occur. Then we explored how the environment affected nest architecture evolution. Spoilers in the title! 🪺🐦🌍

A Causal Inference Framework for Climate Change Attribution in Ecology Accurately attributing ecological shifts to climate change remains a significant challenge. Here, we present an accessible causal inference framework designed for climate change attribution in observ...

not an average american, but living without a car and complaining about the terrible public transportation everyday

you might think N American species are getting common at their north range limit and rare at their south range limit as temps get warmer

but you would be wrong

Comprehensive assessment of snow leopard distribution and population in the Indian Trans-Himalaya, Ladakh: Standardizing methods for evidence-based conservation Effective conservation of threatened species depends on accurate scientific assessment of their occurrence and population status. This information is often lacking or has poor scientific reliability f...

📢 🐾New paper: We developed robust methods to monitor snow leopard population. By implementing it across 59000 sq.km., we found one of the world’s largest snow leopard population and highest densities in Indian Trans-Himalaya. All thanks to local communities and a wonderful collaboration

Reassessing niche partitioning in MacArthur’s warblers: foraging behaviour, morphology and diet differentiation in a phylogenetic context | Biology Letters Owing in large part to Robert MacArthur’s classic research, wood warblers in the family Parulidae are textbook exemplars of species competition and niche partitioning. Conventional wisdom suggests tha...

A lot of blood sweat and tears put into this one: we revisit Robert MacArthur's classic warbler study—with @eliotmiller.bsky.social and colleagues—using, among other techniques, fecal metabarcoding.

Why ‘de-extinct’ dire wolves are a Trojan horse to hide humanity’s destruction of nature Extinction is, for the time being, forever – and a symptom of our global economic system.

“It’s like claiming to have brought Napoleon back from the dead by asking a short French man to wear his hat.”

A short piece in The Conversation by me on why “de-extinction” is nothing of the sort, and bad, bad conservation.

species are on the move in many places due to climate change

we wrote a paper arguing that we need to focus more on the *types* of movements we are seeing, as true range shifts have really different consequences from say range expansions
