Ever wondered how to make your stable isotope data more reliable? 🤔
A lesson from Nate Silver’s election polls might help.

Happy #WorldEggDay! 🥚
A few curious students and a few cartons of eggs led to one of my favourite isotope stories — testing whether “free range” eggs really lived up to their label. Spoiler: the isotopes told the truth.

Delighted to be back teaching on The Survivor's Guide to Stable Isotope Ecology for 2026 - its always a highlight of the year. A fantastic week of isotopic learning in a truly magnificent location. www.exedramc.com/courses/surv...

Food webs are the blueprint of ecosystems.

Want to know what fuels migrating birds? Or how invasive species disrupt rivers and lakes? The answers are in the food web — and stable isotopes let us read it.

Whats in a food web?

Food webs are the blueprint for ecosystems, detailing how nutrients and energy fuel every aspect of life on Earth.

Really neat work James and great to hear that beavers are having, at worst, no negative impact on migrating fishes, while also creating so much new habitat!

Newgrange • The Boyne Valley • Meath

Hoping for clear skies for the #WinterSolstice dawn tomorrow morning.

The world could use a little more light.

Aerial view of Newgrange Passage Tomb in the Boyne Valley, early in the morning. A light mist and low cloud hangs over the monument and surrounding fields.

New article by Rebecca Hale and others in Limnology and Oceanography: "Diel dissolved organic matter patterns reflect spatiotemporally varying sources and transformations along an intermittent stream" aslopubs.onlinelibrary.wiley.com/doi/full/10....

Diel dissolved organic matter patterns reflect spatiotemporally varying sources and transformations along an intermittent stream

Stream dissolved organic matter (DOM) is a globally important carbon flux and a locally important control on stream ecosystems, and therefore understanding controls on stream DOM fluxes and dynamics ...

Aquatic science folks: Would anyone mind sharing a conference poster that presents some kind of water quality time series data?

I'm developing a water science course where students will make a poster on water quality data they collect during the trimester. I would love to provide some examples!

The original ‘tosspot’, in the 16th century, was someone who ‘tossed back’ their ‘pot’ of beer and then immediately went back for another.
