Incomplete lineage sorting and hybridization as sources of gene tree discordance among species of the Geminata clade of Solanum (Solanaceae)

TAXON, Volume 75, Issue 2, April 2026.
Abstract Discordance among gene trees, including discrepancies with the species tree, is increasingly reported in analyses of phylogenomic data. Such discordance can result from technical issues such as misalignment, paralogy, or model misfit, or from biological processes such as incomplete lineage sorting (ILS), hybridization with introgression, or ...

Institutionalised Indigeneity, State Formation and Crisis: Lessons From the Indio Institucionalizado in Evo Morales' Bolivia

Bulletin of Latin American Research, Volume 45, Issue 2, April 2026.
ABSTRACT This article examines the institutionalisation of indigeneity in Bolivia under the governments of Evo Morales (2006–2019) as a central component of the MAS project of crafting state hegemony. We trace the emergence of what we call the indio institucionalizado from the social mobilisations of the 1990s and 2000s through the Constitutional ...

Height and phytotelm size affect the invertebrate communities of epiphytic bromeliads in the Amazon rainforest

Ecological Entomology, Volume 51, Issue 2, Page 221-234, April 2026.
The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

Abiotic drivers of co‐occurrence and diversity patterns of Calopterygidae species in Amazonian protected freshwaters

Ecological Entomology, Volume 51, Issue 2, Page 235-249, April 2026.
Species co‐occurrences rely on their ability to explore similar or distinct available resources, and possible niche overlap can prevent their presence and establishment in a given site Damselflies of the Calopterygidae family demonstrated negative co‐occurrences in streams inside and outside PAs, highlighting that their ecological similarity is ...

Stable isotope data indicate origins of mislabelled historical bird specimens

Ibis, Volume 168, Issue 2, Page 779-784, April 2026.
Natural history specimens provide valuable insights across diverse research fields, but those needing more accurate metadata have limited scientific value. We applied stable isotope analysis to investigate the origin of 19th century Atlantic Forest bird specimens attributed to the northeastern Brazilian state of Pernambuco, which are the only records ...
