Welcome to the team Matt, and thank you for all the help with our field experiments over the summer!

Couldn't afford to include them with a capped budget of £2m. This molecular scale work is very expensive! Next project....

Do pass this on to any budding environmental and analytical chemists! Great opportunity to join this exciting programme!

Thanks. We've recruited two excellent freshwater scientists and are underway now with the first isotope experiments. We'll be recruiting for an experienced omics specialist at postdoc level, and a specialist technician to support them in the autumn. Please spread the word!

I would say we also need action to protect the native biota and food chains in freshwater and marine ecosystems that are distorted, diminished or replaced by these blooms. It's not just about protecting environmental goods and services for 'us' but protecting the environment on its own merits. 🧪
