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

American 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)

American 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

American 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.

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

American 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 ...

Community partner perspectives on community‐academic health research partnerships with Black American communities: A scoping review

American Journal of Community Psychology, EarlyView.
Abstract Evaluations of community‐engaged research (CEnR) typically emphasize health outcomes rather than the partnership processes that contribute to intervention effectiveness. This scoping review synthesized community partner‐identified strategies for successful community‐academic health research partnerships with Black American communities and ...

Recurrent Neurodevelopmental Disorder Associated With a Dominant‐Negative TOP2B H63Y Variant

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT We describe a 7 year‐old boy with severe neurodevelopmental disorder, medically‐refractory epileptic encephalopathy, hyperkinetic movement disorder, hypotonia, cerebral and cerebellar atrophy and hypomyelination who was found to have a heterozygous de novo TOP2B NM_001330700.2:c.187C>T, p.(His63Tyr) variant.

Social Determinants of Health and Health‐Related Quality of Life: The Potential Mediating Role of Social Activities, Access to Medical Services, and Access to Social Services

Australian Journal of Social Issues, EarlyView.
ABSTRACT This study explored the mediating influences of access to social activities, social services, and health and medical services on the relationship between social determinants of health and health‐related quality of life. A survey of 602 adults was conducted in a regional area of Australia.

Has Inequity Faced by Young Australians With Disability Changed Since the Turn of the Century?

Australian Journal of Social Issues, EarlyView.
ABSTRACT Despite the introduction of various policies aimed at promoting equality for people with disability since Australia ratified the Convention on the Rights of People with Disabilities (CRPD) in 2008, there has been little evaluation regarding the extent of change in inequity since then.

A novel target capture probe set reveals widespread unknown hybridization in North American pondweeds (Potamogetonaceae)

Applications in Plant Sciences, EarlyView.
Abstract Premise Advancements in phylogenomics and bioinformatics provide opportunities to more robustly characterize hybrid lineages and incorporate them into phylogenetic hypotheses. Target capture remains the most cost‐effective molecular method of hybrid determination at scale.
