My research focuses on understanding how biodiversity changes in space and time and how disturbances, such as global fisheries and climate change, affect those patterns.

Planetary boundaries are not always protective. Guest Helmut Hillebrand warns that setting limits can lead to their full exploitation.

“Many scholars from historically overexploited countries (often referred to as the global south) expected that exposing the problem would trigger change. Four years on, I see it clearly: the scientific system was never designed for equity,” writes Dolors Armenteras in Nature. #Academicsky 🧪
Equity in science is a beautiful lie — and I’m done pretending
Science isn’t really moving towards equity; institutions are just perfecting the appearance of equity. We need to build an alternative system.

A study in Nature Climate Change shows that the ocean carbon sink unexpectedly declined in 2023 despite record-high sea surface temperatures (SSTs), primarily due to SST-driven outgassing of CO2 in the subtropics. 🌊 🧪
Unexpected decline in the ocean carbon sink under record-high sea surface temperatures in 2023 - Nature Climate Change
The ocean carbon sink strengthened in previous warm El Niño years due to reduced CO2 outgassing in the tropics. Here the authors show that the ocean carbon sink declined in 2023 despite record-high sea surface temperatures (SSTs), primarily due to SST-driven outgassing of CO2 in the subtropics.

In our new Nature Communications article led by Rashmi Paudel, we show that plant species that spread within their native range have a higher probability of becoming established outside their native range.
