Phylogenetics and reticulation among koelerioid clades, part I: Contraction of Trisetum, expansion of Acrospelion, Graphephorum, and Tzveleviochloa; Graciliotrisetum gen. nov. and resurrection of Aegialina (Poaceae, Pooideae, Poeae, Aveninae)

open access: yesJournal of Systematics and Evolution, Volume 63, Issue 3, Page 629-655, May 2025.
Phylogenetic analysis of Koeleriinae clades A and B yielded mostly congruent topologies in nuclear and plastid trees. However, several lineages resolved in strikingly incongruent positions in trees from different data sets, suggesting a reticulate origin for these taxa.

Inequality and poverty in Spain: Insights from a regional convergence analysis

open access: yesInternational Journal of Finance &Economics, Volume 30, Issue 2, Page 1707-1723, April 2025.
Abstract We study the dynamics of inequality and poverty across 17 Spanish regions during 2008–2021. Through a club convergence approach, the results show noticeable differences in both indicators, income inequality (S80/S20) and poverty rate: two clubs are endogenously derived from inequality, while the analysis of the poverty was conducted in four ...

Geographic and Biological Drivers Shape Anthropogenic Extinctions in the Macaronesian Vascular Flora

open access: yesGlobal Change Biology, Volume 31, Issue 2, February 2025.
The anthropogenic extinction patterns and processes of the vascular flora in the model island region of Macaronesia have been investigated in the present study. We compiled all known extinction records, both at global and local scales, across the five archipelagos comprising the region (Azores, Madeira, Salvajes, Canary Islands, and Cabo Verde).

Climb forest, climb: diverse disperser communities are key to assist plants tracking climate change on altitudinal gradients

open access: yesNew Phytologist, Volume 245, Issue 3, Page 1315-1329, February 2025.
Summary Climate change is forcing species to shift their distribution ranges. Animal seed dispersers might be particularly important in assisting plants tracking suitable climates to higher elevations. However, this role is still poorly understood due to a lack of comprehensive multi‐guild datasets along elevational gradients.
