Long‐term demography and spatial genetic structure reveal mechanisms of Sassafras albidum population persistence through clonality

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Vegetative regeneration is a key mechanism of woody plant persistence in forest ecosystems, and the coupled roles of basal sprouting and clonal growth in shaping long‐term population dynamics have been understudied. Basal sprouting replaces stems at fixed ramet locations, whereas clonal growth via root suckering produces spatially ...

Integrative utilization of genomic resources for improved phylogenetic resolution in Sonerileae (Melastomataceae)

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Advances in new next‐generation sequencing (NGS) methods have revolutionized phylogenetics, yet challenges remain in effectively utilizing data from a wide range of sources. A well‐resolved and broadly sampled phylogeny for Sonerileae, the second‐largest tribe in Melastomataceae, is still lacking, hindering our understanding of its ...

Pollination by long‐proboscid horseflies and its implications for reproductive isolation among coflowering Satyrium orchids in South Africa

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Floral adaptations to pollinators can drive lineage diversification and promote coexistence of species. We investigated the reproductive biology of Satyrium longicolle, a South African orchid that we hypothesized to belong to a long‐proboscid horsefly pollination guild and examined overlap of pollinators and floral traits among ...

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

open access: yesAustralian 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.
