Check out this new paper led by Adam Spitzig in PNAS - how cultural changes in the past can shape biodiversity patterns

We have more #biodiversity data than ever — from 🛰️, field work, citizen obs., and Indigenous knowledge.
But, are we halting biodiversity loss? The answer is uncertain.
Why? Because the chain of evidence needs to be stronger
Our new #PNAS paper proposes a way forward

New PNAS study finds climate change could shrink 36–50% of global grazing land by 2100, threatening livelihoods of 100+ million pastoralists, with Africa among the hardest hit.

Hello Bluesky!
Does Nₑ really explain mutation rate (μ) or genome size (GS) in vertebrates?
We find the apparent Nₑ–μ link in Bergeron et al. (2023) is a “back-door” path via generation time, and GS is decoupled from both Nₑ and life-history traits.

Fruit flies change what they eat when they’re stressed and those choices can help them survive. New PNAS research highlights how illness drives adaptive “self-medicating” diets. 🧬🍃

our recent #PNAS article "The intensification of the strongest nor'easters"

Scanning electron microscope image of zircon crystals in black and white. Each crystal is about 0.1 millimeters in size, which is roughly the thickness of a human hair, and records cosmogenic krypton as a geochemical time archive. The pieces themselves are a range of shades from white to black with lines and patterns on them. The image belongs to the researcher Max Dröllner.
The researcher is photographed on a pale sandy beach in Australia. The landscape is empty and the sky is blue and sunny. There is lots of surf (white) in front of turquoise water and there is land with dark foliage in the background. The beach is strewen with dark seaweed and only the footprints of the researcher (Maximilian Dröllner) are visible on an otherwise smooth beach. He has binoculars and sunglasses but looks wrapped up against the cold or wind.

This funny pic reminded me of the 2014 nonsense paper about female hurricanes being deadlier than the male ones. Done by mathematical modeling at departments where nobody had any competence about meteorology.
(they meant female-named, which people would take less seriously). #PNAS, who else?
New paper in #PNAS tracking landscape evolution in deep-time through #cosmogenic krypton in #zircon. New tool adds additional versatility to the Swiss army knife timelord mineral enabling access to cryptic Earth surface aspects of grain histories.
