The effect of extreme wildfire exposure on energy poverty: Evidence from Australia's Black Saturday bushfires

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This study assesses the effects of the 2009 Black Saturday Bushfires (BSB), which primarily occurred in rural regions of Victoria and represent the deadliest bushfire event in Australia's history, on household energy poverty. Using a linear panel event‐study, an entropy‐balanced event‐study, and a staggered difference‐in‐differences (DiD ...

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Success of coastal sage scrub restoration is influenced by local adaptations of shrub species

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Restoring plant communities is increasingly challenging with climate change. While practitioners have traditionally used local seed sources, many are recommending assisted migration, possibly from more extreme environments such as inland rather than coastal environments, for restoration.

Floral traits and hermaphrodite abundance shape female advantage in a gynodioecious plant

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Gynodioecy is maintained through female advantage in seed fitness that depends on the sex ratio of a population. We hypothesized that females of Silene acaulis would exhibit floral traits associated with elevated outcross pollination and that sex ratio would impact pollen limitation and inbreeding depression such that female advantage ...

A tribal‐scale phylogenomic perspective on ancestry and major lineages of the allotetraploid Hawaiian silversword alliance (Madieae, Compositae)

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Disentangling the ancestry of insular plant lineages is important for resolving their evolutionary histories but often complicated by polyploidy, an overrepresented condition in remote island floras. We used a phylogenomic approach to study the origin of subgenomes of the tetraploid Hawaiian silversword alliance and advance ...

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.

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
