Plant diversity enhances ecosystem resistance to increasing grazing pressure in global drylands - Nature Ecology & Evolution Grazing affects plant diversity, but plant diversity in turn may modulate the effect of grazing on the plant community. This global analysis explores the association between plant species richness and...

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

Yes, but no effects of landscape context were detected - except on natural pest control

🌾 Overall, cover crop choice matters: diverse cover crop maximize ecosystem benefits, while herbicide-based management reduces them. 🏞️ Surrounding semi-natural habitats (grasslands, woodlots) amplify positive effects of local mgmt especially for natural pest control (Photo: S. Richart-Cervera)

🔋 The strongest positive responses to extensive management were found for :
• Carbon sequestration +37.8%
• Erosion control +26.4%
• Soil fertility +19.9%
• Pest regulation +16.4%

🌱 “Extensive” practices include permanent cover crops, organic farming, and reduced pesticide use — all contributing to benefit biodiversity & ecosystem services

🍇 Check out this meta-analysis led by Silvia Winter about the impacts of vineyard management and landscape context on biodiversity & ecosystem services. Overall, we found that extensive management increases biodiversity and ecosystem services. www.sciencedirect.com/science/arti...

A graph of atmospheric carbon dioxide concentrations at the Mauna Loa observatory, Hawaii, from 1958 to 4th February 2025. It shows carbon dioxide levels rising at an accelerating rate over the decades. This is known to be due to emissions of carbon dioxide from human activity, mainly fossil fuel burning but also deforestation. The first CO2 concentration value in March 1958 was 315 parts per million (ppm). The latest daily value is 426 ppm. The graph also shows a seasonal cycle of a few ppm within each year, which is known to be linked to the growing season in the northern hemisphere causing a temporary uptake of carbon in spring and summer and release in autumn. The graph is produced routinely by the Scripps Institution of Oceanography, UC San Diego.

Although NOAA's page on atmospheric CO2 levels has vanished, you can still get this vital information from Ralph Keeling's team at the Scripps Institution of Oceanography, UC San Diego keelingcurve.ucsd.edu

We need to all collectively decide to stop propping up these journals (MDPI and “Frontiers In” megajournals) by lending them our credibility.

Every time you submit to, review for, guest edit, or even cite (??) these journals, you lend them your hard earned credibility.

Don’t do it.

Last but not least. 🍇
