Great time speaking at the #IBA2025 on nature-related financial disclosures.
For nature markets to be credible and avoid green-washing, we have to solve the Measurement, Reporting, and Verification problem and make reliable nature data a public good.

Blessed to find this beautiful electric blue Faxonius virilis while sampling the St. Lawrence for my doctoral work! This is a fairly rare phenotype for this native North American species!

Our new forum piece is out now in @cp-trendsecolevo.bsky.social 🥳

We argue that existing & expanding regulations to protect specific animal groups from light pollution 💡 (e.g. bats 🦇 marine turtles 🐢 insects 🦋) might co-protect many other organisms ...

🧵 REVEALED: Community energy projects in Scotland are generating 100x more local wealth than privately-owned wind farms.

But just 0.5% of the renewable power is community-owned. Why this staggering imbalance?

Happy #DeepDay. The deep sea seems so far away and yet we are more connected to it than we think.

I consider myself very lucky that my work allows me to go to and study this amazing ecosystem.

What if everyone had a biobank in a matchbox?
A distributed seedbank; shared by post, scattered with care.
Not stored in vaults like in Svalbard or Wakehurst Place but alive in our laneways, verges, windowsills.
Guerrilla rewilding.
Cheap. Communal. Powerful.
A future held in every pocket. 🌍
An ecosystem in a matchbox served as an ice-breaker at a meeting of a new Dublin biodiversity network on Saturday. It’s meant to be a forum for sharing ideas, and knowledge – and working together to push for change. www.dublininquirer.c...
