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....

A new study by @alexpigot.bsky.social and colleagues reveals the critical role of biodiversity in the functioning of ecosystems.

Looks interesting 🧐

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.
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 🌿🌏 🧪

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.
Here is the video recording of my talk exploring what energy flow through ecosystems can tell us about nature's health and functions, and in particular, bring the roles of animal wildlife more firmly into our understanding of how the biosphere functions

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

This is figure 1, which explores ecosystem transition potential across the Amazon forest biome as a result of compounding disturbances.
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 🧪
