Temperature‐dependent pollinator‐mediated selection on floral thermoregulation

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1716-1726, February 2026.

Most plants cannot choose their microclimate, so understanding how they cope with thermal variability is of critical concern. Several floral traits can modify the floral thermal microenvironment, which may alleviate negative impacts of thermal extremes on gametophytes and

Trait‐based species selection for restoration: A case study from tropical landscapes dominated by bracken

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our results can be used by stakeholders to select the species best suited for active restoration projects in bracken‐dominated areas throughout the tropical region. Furthermore, our trait‐based approach, which considers seedling performance in disturbed areas, can serve as a guide for species selection in restoration programmes in other disturbed ...

A new phylogeny of Anastrepha (Diptera: Tephritidae) based on nuclear loci obtained by phylogenomic methods

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and

2D Assemblies Based on a Tetraphenylethylene D,L‐Cyclic Peptide Scaffold

open access: yesAngewandte Chemie, Volume 137, Issue 52, December 22, 2025.
A new scaffold based on four nanotube‐forming cyclic peptide units attached to a tetraphenylethene (TPE) core with pH‐dependent self‐assembly that provides light‐emitting 2D nanosheets with controlled thickness is described. Abstract Two dimensional (2D) materials and aggregation‐induced emission (AIE) fluorophores have recently gained attention due to
