We conducted a transplantation experiment along a 1000-m elevation gradient in the Alps to quantify changes in plant abundance due to climate warming and how those were predicted by eco-physiological performance versus common morphological traits. We show that while easily measured morphological traits partly predict plant abundance responses to climate, eco-physiological traits are needed to understand the underlying mechanism.

We developed and tested a submersible standalone pumping device allowing targeted marine water filtering to explore the biodiversity of two mesophotic ecosystems using #eDNA metabarcoding, one temperate along the Provence coast in the North-Western Mediterranean Sea and one tropical at the seamount La Pérouse in the Western Indian Ocean.

High resolution ~12,000 years sedimentary DNA from Lake Sulsseewli shows that alpine plant diversity is associated with human land use and climate change.

High resolution ancient sedimentary DNA shows that alpine plant diversity is associated with human land use and climate change - Nature Communications

Here, the authors use sedimentary DNA, pollen, fungal spores, chironomids, and microcharcoal from an alpine lake core to reconstruct vegetation across 12,000 years. They find that vegetation responded to climate in the early Holocene, followed by a shift to human activity from 6000 years onward corresponding with an increase in deforestation and agropastoralism.
