By developing the first multispecies NIRS-based open-source model to quantify faecal nutrient concentrations in different herbivore species in the Icelandic tundra, we take an important step towards affordable, standardised monitoring and new insights into Arctic nutrient cycling.

... and that most nutrients were deposited early in the growing season: a crucial pulse for plant growth.

🔬 We scanned 300+ faecal samples and calibrated a NIRS model.
We found big differences between species and over the growing season.

Despite their small size, we found that geese contributed the most nutrients to the ecosystem, thanks to their large numbers & high defecation rates...

🦌🦢🌿How do tundra herbivores shape nutrient cycles?

We developed the first multispecies NIRS-based open-source model to quantify nitrogen, phosphorus & carbon in faeces of tundra herbivores in Iceland (geese, reindeer, sheep).

🌸Plant diversity dynamics over space and time in a warming Arctic 🌸

Our new study @nature.com analysed plant diversity change in >2000 tundra plots over 4 decades. We found that plants changed unevenly, mostly driven by warming and biotic interactions.

Today hundreds of Nuummiut and also Sisimiormiut Tasiilarmiit Qaanaarmiut and other greenlandic towns demonstrated peacefully against repeated threats to annex our country.

New paper out! 🦌 We dive into 30 years of research on Iberian wild ungulates. From hunting to disease dynamics, we review their impacts and call for adaptive management to balance conservation and coexistence. Read more here: onlinelibrary.wiley.com/doi/10.1111/...
