The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

open access: yesBiological Reviews, Volume 101, Issue 4, Page 2053-2076, August 2026.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Studies on Pygmy Grasshoppers: Bogotatettix Cadena‐Castañeda, García‐García & Tavares, gen. nov. (Orthoptera: Tetrigidae), a New Genus From the High Andean Forests and Páramos

open access: yesAustral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT In this contribution to the study of pygmy grasshoppers, a new genus is described, which inhabits the high Andean forests and páramos surrounding the Bogotá Savannah, Colombia. Bogotattetix Cadena‐Castañeda, García‐García & Tavares, gen. nov. includes a new species, Bogotattetix chingazaensis Cadena‐Castañeda, García‐García & Tavares, sp. nov.

Si─Si Bonding in an Unsupported N‐Heterocyclic Silylene Dimer Stabilized by an Iminophosphorane‐Based Scorpionate Ligand Versus Head‐to‐Tail Coordination in the Sn and Pb Tetrylenes

open access: yesChemistry – A European Journal, Volume 32, Issue 25, 2 July 2026.
A new iminophosphorane‐based scorpionate ligand enabled the characterization of a head‐to‐head silylene dimer with unsupported Si─Si bonding, whereas the tetrylene species of Sn and Pb afforded head‐to‐tail coordination polymers in the solid state. ABSTRACT N,N‐chelating ligands disfavor element–element bonding in heavier alkene analogs of group 13 and

Seed encapsulation improves early recruitment in seed‐based restoration: Evidence from partitioned germination outcomes in a temperate forest

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Capsules in the forest: using unmanned aerial vehicle deployment, we tested pelleted capsules and engineered pods in greenhouse and field trials. Pods improved early field establishment compared with pelleted capsules, while predation remained a major limit to final survival.
