Haar kept moth numbers down at Findhorn dunes (VC 95) last night, with a meagre return of 15 species across two traps. However i did find a nice Portland moth / Actebia praecox resting on the heather, and an attractive Arctosa perita sought refuge (or prey) inside one of the traps
🧪🚨Ever wondered why plant leaves 🍃look the way they do? Glad to contribute to work by Jamie Malone & team on developmental bias toward simple leaves! But there’s a backstory to it 1/4

Excited to see one of my PhD chapters now published! We found a trade-off between the quality of host plants and how warm they were for a declining grassland butterfly (Small Copper, Lycaena phlaeas) and looked at how this shaped their egg-laying choices: doi.org/10.1111/een....
Really excited to present the results of a fantastic collaboration with Jesse Veenvliet @jesseveenvliet.bsky.social @mpi-cbg.de @poldresden.bsky.social 🤩
We find a unique mechanism for body axis elongation in mammals, different from other vertebrate species

I am excited to share the first preprint from my postdoc work! We found that ligand-receptor pairs are not static and show an antagonistic spatial localization! We show ligand is important to fine tune the amplitude of Wnt oscillations ensuring robust tissue patterning! Check out the preprint!
The introduction and Part 1 of my South Africa blog are now published. Beware that this post is extremely long - so long, in fact, that I'm not sure how I'm going to find the time to keep this up for the rest of the trip

The relative influence of developmental bias and natural selection on evolutionary outcomes remains a central, unresolved question in evolutionary biology. Here, we combine large-scale phylogenetic tr...

Preprint alert!
We combined microfluidics, proteomics, and RNA-seq to map spatiotemporal protein expression during mouse somitogenesis and found a novel regulatory strategy: dynamic antagonistic gradients fine-tune signalling strength.
