We are glad to share our recent article pulbished in @pnas.org, where we we demonstrate that plant species that occupy larger geographic ranges tend to have broader climatic niches and are more likely to achieve high local abundances.

Very happy to finally see this out in @pnas.org. Great work (masterfully) led by my dear friend @gabrielmoulatlet.bsky.social on a classic question on range sizes, climatic niches and dominance for plants at the global scale!

Thanks for the collab, Gabriel!

in "General laws of biodiversity: Climatic niches predict plant range size and ecological dominance globally", we provide key insights into species’ vulnerability to environmental change and the processes that structure biodiversity at global scales.

Why are some species widespread while others are found only in small, isolated areas? A study in Nature Communications shows that species with narrow ranges, and thus higher extinction risk, are often island-restricted, poor dispersers, and have evolved relatively recently. #evosky 🧪

A new @natcomms.nature.com study led by iDiv alumna @adrianaalzate.bsky.social @naturalis.bsky.social uncovered that across >26,000 species evolutionary age is positively linked to range size, except in marine mammals.

Older species tend to have large ranges – unless they live on islands
New Nature Communication publications sheds light on how ecological, evolutionary, and geographical processes can simultaneously shape species’ vulnerability to extinction.

New from me: How China's clean energy manufacturing boom is helping reduce CO2 emissions overseas. In 2024, China’s exports of solar panels, batteries and electric vehicles are shaved 1% off global emissions outside of China.
carbonbrief.org Carbon Brief @carbonbrief.org · Jul 21
NEW – Analysis: China’s clean-energy exports in 2024 alone will cut overseas CO2 by 1% | @laurimyllyvirta.bsky.social

Read here: buff.ly/V7BVSsL
China’s clean-energy footprint spans essentially the entire world, with exports to 191 of the 192 UN member states, excluding China, manufacturing plans in 25 countries in 12 of the 17 UN regions and clean-energy project financing in 27 countries in 11 regions.

I’m 39. 3 years ago I left academia.

My biggest regret?
Not building a network outside it.

I thought great science would be enough.
It wasn’t.

Visibility builds trust

Visibility opens doors — especially when you leave the lab.

Start showing up. Share your Science.

Start now.

Hand-drawn infographic showing two network diagrams. The first diagram is labeled “With Academic Networks” and shows a central circle labeled “You” connected to a few surrounding circles, each linked to a single star. The rest of the stars (representing opportunities) float disconnected in the background. The second diagram is labeled “With Academic + Non-Academic Networks” and shows the same central “You” circle connected to many surrounding circles, each linked to one or more stars, representing a higher number of opportunities. Below the diagrams, a key indicates that each star symbolizes an opportunity.
