Exploring Andean foothill connectivity: insights from population divergence in the white‐tipped sicklebill, Eutoxeres aquila

Journal of Avian Biology, Volume 2026, Issue 3, May 2026.
The Northern Andes, acting both as barrier and corridor, exert strong influence in Neotropical biodiversity. Still, the diversification of foothill taxa inhabiting ecotonal zones between lowland rainforest and montane environments in this region remains poorly understood.

A new phylogeny and phylogenetic classification for Solanaceae

TAXON, Volume 75, Issue 2, April 2026.
Abstract Solanaceae are a globally distributed family of considerable economic importance. Recent phylogenetic work on various clades in the family has resulted in a plethora of names at various taxonomic levels. This results in a confusing set of names applied to clades at different ranks, and to the use of informal names that are often not accepted ...

Simplified, Portable and Cost‐Efficient Airborne eDNA Metabarcoding to Expand Tropical Biodiversity Assessments

Environmental DNA, Volume 8, Issue 2, March/April 2026.
This study introduces a liquid‐based sampling approach for airborne eDNA (A). Using a greenhouse mock‐community for optimization (B), we use the novel approach in the tropical Andes to demonstrate its versatility and the complementary nature of airborne and aquatic eDNA for molecular biodiversity assessments (C).

To be or Not to be Hybrids? A Case‐Study in an Allochthonous Population Involving Illegal Introductions of the Endangered Golden‐Headed and Golden Lion Tamarins

American Journal of Primatology, Volume 88, Issue 1, January 2026.
Genetic analyses of an allochthonous population of Leontopithecus, illegally introduced into an area of the Brazilian Atlantic Forest in Rio de Janeiro, did not detect signs of hybridization. This data provides crucial information to support conservation efforts and prevent new threats to the endangered lion tamarins. ABSTRACT Allochthonous species can
