Drylands are globally resistant to invasive species!

Native biodiversity and aridity are key but increasing grazing pressure and eutrophication may change the game 🌐

Abiotic and biotic controls of non-native perennial plant success in drylands - Nature Ecology & Evolution

It is unclear whether the harsh abiotic conditions of drylands hinder biological invasions. This global analysis shows that drylands are vulnerable to non-native plants and are likely to become more s...

Concentrations of PFAS, or “forever chemicals,” in North Atlantic pilot whales peaked in 2011 and have since dropped by more than 60%, thanks to phase-outs of specific chemicals. Replacement chemicals are not showing up in whale tissue. In PNAS: https://ow.ly/YEFe50Y6yMS

We quantify multiple ecosystem services in rangelands with standardized global data from #NutNet 🦌🐄🦬, and show how their synergies and trade-offs shift with grazing exclusion and fertilization 🌿🌏💫

In herbaceous plants, phenols are driven by grazing pressure and foliar nitrogen, while woody plants respond mainly to climate (precipitation & temperature).

Livestock and climate change thus reshape plant secondary metabolites, with consequences for ecosystem functioning and forage quality 🌍🌱

Plant phenolics play a key roles in plant strategies.

Grazing is a major land use in drylands with major impact on ecosystems

In a new paper, we found that plant diversity is key to increase ecosystem resistance to increasing grazing pressure. This effect is driven by complementarity in plant traits
