Birds That Don't Exist: Niche Pre‐Emption as a Constraint on Morphological Evolution in the Passeroidea

open access: yesEcology Letters, Volume 29, Issue 2, February 2026.
We use topological data analysis to reveal a persistent morphological gap in a major group of songbirds (superfamily Passeroidea). The gap remained unoccupied for millions of years, even though nearby morphologies are common and the same body form exists in other groups of birds.

Variation in Tree Growth Increases With Global Warming

open access: yesEcology Letters, Volume 29, Issue 2, February 2026.
In recent decades, considerable research has focused on the long‐term trend of tree growth rates under global warming, yet little attention has been paid to trends in high‐frequency tree growth variations—that is, year‐to‐year differences in growth rates.

Multiple Key Hosts and Network Structure Shape Viral Prevalence Across Multispecies Communities of Bees

open access: yesEcology Letters, Volume 29, Issue 2, February 2026.
This study develops a quantitative framework that integrates field data, epidemiological models, simulations, and Bayesian inference to identify key viral hosts in multispecies bee communities. By estimating species‐specific R0 values from flower‐visitor networks and viral screening, we show that honeybees, as well as other wild bees, can drive the ...

Debate vicario de la vida política, la caricatura lleva siglos registrando el devenir social, sin ahorrarse los conflictos a los que se arriesga toda burla al poder. En este artículo, Macarena Langleib analiza la caricatura política, a partir de una recuperación histórica y una contextualización actual, en el mundo y en Uruguay. Aproximaciones teóricas

The Critical Role of Coefficients: Updating Allometric Normalisation Constants for Modern Ecology and Modelling

open access: yesEcology Letters, Volume 29, Issue 2, February 2026.
Allometry is central to a wide range of ecological research including dynamic food web modelling. Here we updated the often neglected allometric coefficients for metabolism and production, deriving new genus and metabolic group levels estimates with phylogenetic hierarchical modelling providing robust inference.

Development of a lip colour chart across four ethnicities

open access: yesInternational Journal of Cosmetic Science, Volume 48, Issue 1, Page 161-171, February 2026.
The present study revealed a large lip colour diversity across four ethnic groups. The inter‐group overlaps demonstrate that lip colour is not solely defined by individual ethnic belonging. The 53 lip tones described here could be used as target shades to create more inclusive nude lipsticks in the near future. Abstract In the human face, the lips play
