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 ...

Longitudinal Echocardiographic Surveillance of Aortic Dilation in a Phenotype‐Enriched Turner Syndrome Cohort

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Turner syndrome (TS) is associated with thoracic aortopathy and increased risk for aortic dissection, yet the natural history of aortic dilation is not well understood. We performed a retrospective longitudinal study of individuals with TS who participated in the TS Society of the United States Healthy Heart Project between 2003 and 2023 ...

Scale‐space image analysis for mapping spotted knapweed in grassland ecosystems

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise This study investigates the value of scale‐space representations of spatial features for the identification and mapping of invasive plants using high‐resolution multispectral imagery. Scale‐space representations combine the two‐dimensional spatial domain with a third dimension representing spatial scale, such that features can be ...
