Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Environmentally induced dynamics between intraindividual variation and trait means across vegetative, phenological, and floral traits

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Intraindividual variation in reiterated structures (e.g., leaves) represents an important dimension of phenotypic variation that contributes to functional diversity and the dynamics of ecological communities. It can be expressed differently across plant traits, but how environmental drivers affect intraindividual variation in different

Hemiparasitic Castilleja presence is correlated with increased plant biodiversity across montane plant communities

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Root hemiparasites form haustoria in belowground roots of hosts to extract nutrients and water from the surrounding hosts. Through parasitic symbiosis, these plants disproportionately affect plant communities relative to their abundance by reducing host size, altering nutrient flow, and eventually increasing local biodiversity.

Negotiating contested spaces and places: Narratives of social suffering and resistance in racialized Cape Town communities

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This study employs a schizocartographic approach to explore community narratives of space, memory, and violence in Kraaifontein, Cape Town. Through participants' accounts, ordinary places—gardens, shops, blocks, sports grounds, and streets—emerge as ambivalent geographies where trauma, resilience, and belonging intersect.

Health‐Related Quality of Life, Everyday Executive Functioning, and Eating Behavior in Adults With Bardet–Biedl Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Bardet–Biedl syndrome (BBS) is a rare genetic condition with a broad phenotypic spectrum. Knowledge about quality of life, executive functioning, and eating behavior in adults with BBS remains limited. This study aimed to assess health‐related quality of life (HRQoL), everyday executive functioning, and eating behavior in adults with BBS and ...
