Our new @science.org paper is out! Cuckoos and hosts are locked in a coevolutionary arms race over egg mimicry.
But how are these egg types inherited, and could this drive speciation? We sequenced hundreds of genomes to find out!

Genomic architecture of egg mimicry and its consequences for speciation in parasitic cuckoos
Host-parasite arms races facilitate rapid evolution and can fuel speciation. Cuculus cuckoos are deceptive egg mimics that exhibit a broad diversity of counterfeit egg phenotypes, representing host-ad...

day 2 #InverteFest #invertebrate weird fact:
there are some ants with only a single chromosome, while some butterflies shred their genome into multiple "microchromosomes" 🧬🐜🦋

🚨🐜!!! Check out our new paper where we investigate the impact of a soil level (SoilTemp) dataset on niche shifts of introduced ant species globally — using soil temperatures often lessens the extent of niche shifts between native and introduced ranges! 🐜 🐜 onlinelibrary.wiley.com/doi/10.1111/...

1/7 Cumulative culture/knowledge occurs when information builds up across generations through a combination of innovation and transmission. In our new paper, we investigate the role of teaching and its coevolution with learning in this process.

Excited to share our new preprint on barn owls revealing how parental roles are flexibly negotiated outside the nest! Using simultaneous GPS + accelerometer tracking, we captured 20,000+ hunting attempts from 68 breeding pairs:
