We know that marine fishes 🐠 have an inverse gradient of speciation compared to that of spp richness, with higher speciation at higher latitudes. But, what about freshwater 🐟?

Exxon funded thinktanks to spread climate denial in Latin America, documents reveal Texas-based fossil fuel company financed Atlas Network in attempt to derail UN-led climate treaty process

Big Oil has a long history of interference in Latin America.

Documents reveal that "Exxon funded rightwing thinktanks to spread climate change denial," invest in "market-oriented public policies" and ensure "continued strong returns to Exxon’s investors.” 😑

How Ancient Indigenous Societies Made Today’s Amazon More Resilient - Eos Portions of the forest managed by pre-Columbian populations hold higher biomass and are more able to withstand climate change.

The future of the Amazon may rely on its past. According to study, landscape interventions by the forest’s pre-Columbian Indigenous inhabitants might still affect its ecological functions, including its capacity to store biomass, absorb carbon, and withstand climate change

Earth's largest land animals are limited by salt.

Sodium availability constrains the density and distribution of elephants, giraffes and rhinos across Africa, and offers a new explanation for the so-called 'missing megaherbivores'.

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!

Evolutionary age correlates with range size across plants and animals - Nature Communications Why are some species widespread while others are found only in small, isolated areas? This study shows that species with narrow ranges, and thus higher extinction risk, are often island-restricted, poor dispersers, and have evolved relatively recently.

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.

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.
