Dispersal and delimitation: Phylogenomics of Connaraceae prompts revised generic delimitation in Cnestideae and reveals global biogeographic patterns

open access: yesTAXON, Volume 75, Issue 2, April 2026.
Abstract The tempo and mode of assembly of the world's most diverse, tropical floras remain poorly known. Evolutionary relationships within pantropical plant clades such as Connaraceae (Oxalidales, ca. 220 species) offer an opportunity to address this issue.

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

open access: yesTAXON, 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 ...

Tetraopes Milkweed Beetle Genomes Elucidate the Adaptive Basis of a Temperate Coevolutionary Radiation

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT The coevolutionary radiation of 27 species of Tetraopes longhorned beetles and their Asclepias milkweed hosts represents a classic example of adaptive evolution driven by plant chemical defences and herbivore counteradaptations. Investigations to date, however, have focused on a single species, Tetraopes tetrophthalmus, which feeds on the ...

Cuba's Three Autocratic Transitions: From Revolutionary Regime to (Post)Totalitarianism and New Authoritarianism?

open access: yesBulletin of Latin American Research, Volume 45, Issue 2, April 2026.
ABSTRACT Cuba is the oldest and most consolidated autocracy in the Americas. Its Revolution in 1959, the charisma of Fidel Castro, the single‐party system and the US embargo have made the island an exceptional case. However, recent developments such as popular protests, limited reforms, emigration or socio‐economic decline are bringing about some ...

Devolved Invisibility: Identity and Belonging Among Latin American Communities in Scotland

open access: yesBulletin of Latin American Research, Volume 45, Issue 2, April 2026.
ABSTRACT In a nation known for welcoming migrants and its history of transnational solidarity but marked by colonial amnesia, this article addresses the research gap on Latin American communities in Scotland. It focuses on first‐generation migrants who settled in Scotland in the 21st century, examining how they negotiate identity and belonging against ...

Revealing patterns of endemism in the transatlantic family Chelodesmidae (Polydesmida: Diplopoda)

open access: yesCladistics, Volume 42, Issue 2, Page 159-171, April 2026.
Abstract With fossil records dating back to the Silurian/Late Ordovician, millipedes stand out as one of the earliest terrestrial animal groups. Their limited vagility and high endemism make them valuable tools for formulating and testing biogeographic hypotheses, including those related to macro‐vicariance events.
