Impacts of management on ecosystem service capacity in northeastern U.S. Appalachian forest stands Forests are critical resources that provide multiple ecosystem services. However, the capacity to produce these services depends on how forests are managed. The northeastern US is a highly forested an...

New paper in @canjforestres.bsky.social. We looked at changes in forest productivity and biodiversity in harvested and non-harvested forest stands in northern Appalachia. Lower harvest intensities and longer rotations support multiple ecosystem service capacity 🌎🧪🏡

Misinformatie in het zorgdebat Hoe RTL en NOS in een spookcijfer trapten

@rtl.nl en @nieuws.nos.nl verspreidden een spookcijfer. Al in 2017 werd dit getal uit 2011 gedebunkt, maar bij het verkiezingsdebat zeven jaar later (!) popt het gewoon weer op.

Hoe het wel zit? Dat laten wij zien in deze nieuwste nieuwsbrief.

Elon Musk donates $1 million for archaeological sites in Rome Through the Musk Foundation, the foundation established in 2021 to support international humanitarian and scientific projects, Elon Musk, has chosen to fund a program dedicated to Rome's archaeologica...

I am once again telling you that taking money from Musk makes you complicit in his instrumentalization of cultural heritage to support his beliefs. Taking funding from amoral entities is, in my opinion, not ethical and it is in fact harmful. www.finestresullarte.info/en/news/elon...

Want to learn something about #water and #climate change?
A simple approximation is that for every degree C of warming, the atmosphere holds 7% more water. That's one factor behind the growing number of extreme flooding events.

Too often, I see people talk about a replication as if the first study has established something, and the replication study is a double-check. What people often fail to understand is that we do not do replication studies to *check* a finding, but to *establish* a finding. 1/x

Bolton Museum displays rare Roman sun hat following restoration The 2,000-year-old hat, which kept soldiers cool in Ancient Egypt, is one of only three in the world.

The artefact, believed to be one of only three similar headpieces remaining in the world, was held in storage at Bolton Museum for more than a century until a private donation led to its restoration.

Energy chief suggests Trump administration is altering previously published climate reports | CNN Wright said the Trump administration is updating the National Climate Assessments that have been previously published, which the administration recently removed from government websites.

The Trump administration has deleted all previous National #Climate Assessments from government websites and fired the scientists working on the next report. Now they say they're going to rewrite the previous ones.
This is scientific sabotage and a rewriting of history.

Soviet poster titled "The enemy is full of guile and evil" - espionage, sabotage, slander, provocations, lies

1/ Donald Trump's reasons for his firing of the head of the US Bureau of Labor Statistics are an ominous echo of a notorious concept from Stalinist Russia and Nazi Germany: that of scapegoating individuals or groups as economic "wreckers" or "saboteurs". ⬇️

Continents are drying! 🔥 🧊 💧
