Do montane birds evolve more efficient wing shapes for flying at high elevations? Our global analysis published today suggests that they do! 🧵(1/8)⬇️ www.cell.com/current-biol....

Macroecological rules predict how biomass scales with species richness in nature
Despite advances in theory and experiments, how biodiversity influences the structure and functioning of natural ecosystems remains debated. By applying new theory to data on 84,695 plant, animal, and...

The lack of evidence for declining local diversity through time must be because everything is homogenizing, leading to larger-scale losses.

Right?!

Nope, says our analysis of 500+ meta-communities through time just published in Science Advances

Synthesis reveals approximately balanced biotic differentiation and homogenization
Homogenization is most common at large temporal and spatial scales but is balanced by differentiation at smaller scales.

If you missed @ymalhi.bsky.social talk last Friday on what an energetic view of life on Earth can tell us about nature decline and recovery, you can watch it here now: youtu.be/t35HLM6BZI0

Exciting update! @copernicusecmwf.bsky.social - launch the Interactive Climate Atlas

atlas.climate.copernicus.eu/atlas

This new tool builds on the data of the IPCC Climate Atlas and enables exploration of CMIP6 climate projections and other datasets including observations and reanalysis.

Between 10% and 47% of Amazonian forests may be exposed to climate stresses that could push the biome past a tipping point as soon as 2050, according to a paper in Nature. go.nature.com/4bG7nWC 🧪
This is figure 1, which explores ecosystem transition potential across the Amazon forest biome as a result of compounding disturbances.

Prob the best studied climate-related range expansion of any European #birds is the Cetti’s Warbler. This skulking brown bird is the sole European representative of a largely Asian genus & is a resident species of reedbeds & wet scrub. 1/N 🌿🌏 🧪

A rare relatively unobscured image of a Cetti's Warbler, probably singing. It is a warm brown on the head, back wings and tail fading to white on the throat and belly with a tiny white eye-stripe. Beady black eye and that's about it. Half hidden by a bunch of twigs.
