Fine‐scale genetic structure of the cloud forest tree Ocotea psychotrioides revealed by genome‐wide SNP data

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Recent advances in genomic technologies now enable the reconstruction of evolutionary histories at fine spatial scales, illuminating the complex dynamics that shape biodiversity patterns in naturally discontinuous, archipelago‐like ecosystems such as cloud forests.

A mid‐Cretaceous monocot flower from the Dakota Sandstone of Kansas and its potential implications for the fossil record of palms

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Although the megafossil flora of the upper Albian–lower Cenomanian Dakota Formation in Kansas is well known for angiosperms, monocots have not been reported previously. Methods A mesofossil flower was discovered by X‐ray analysis of a specimen collected more than a century ago from the Dakota Sandstone of central Kansas.

Genetic diversity and differentiation of a partial mycoheterotrophic orchid (Cymbidium macrorhizon) under urbanization

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Urbanization exerts substantial pressures on the genetic diversity of plant species, but the direction and magnitude of urbanization impacts may vary depending on species‐specific life history characteristics. To better understand the relationship between life history and urbanization effects, we assessed genetic diversity and ...

Border harm and affective injustice: The politics of anger at the Melilla border, Spain

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This article examines protests in a detention center in Melilla, Spain—a site where structural violence intersects with the everyday harms of confinement. Adopting a justice and dignity‐centered perspective, we analyze grassroots forms of resistance emerging at the border. The study focuses on the protests of Tunisian migrants and explores the
