Aging and longevity in decades‐old genebanked seeds from U.S. endangered plant species: Assessments using survival and RNA integrity assays

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Seed longevity is critical for successful genebanking, but it is hard to detect or predict. We examined survival of genebanked seeds from species native to the United States to estimate longevity. We tested whether RNA integrity (RIN) can be used to detect aging and predict mortality. Methods Dry seeds from >100 species were stored for

Biological control of Rubus alceifolius (Rosaceae) in La Réunion Island (Indian Ocean): from investigations of the plant to the release of the biocontrol agent Cibdela janthina (Argidae) [PDF]

open access: yes, 2011
The giant bramble (Rubus alceifolius Poir.: Rosaceae), native to Southeast Asia, is one of the most invasive plants in La Réunion. A ten year research program was launched in 1997 with three components: i) genetic diversity, ii) development strategy, and

Soil, competition, and niche shifts shape the floral mosaic of an annual plant diversity hotspot

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Plant species with affinity for harsh substrates often have well‐defined edaphic (soil) niches and are ideal for exploring questions of community assembly. Vertic clay soils are chemically and physically challenging to plant establishment and productivity, and annual plant communities associated with these soils of the San Joaquin ...

Spring ephemeral Erythronium umbilicatum may not be vulnerable to phenological mismatch with overstory trees

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The defining life history strategy of spring ephemeral wildflowers is their avoidance of shading by trees during the brief, high‐light period before canopy leaf out. Studies suggest that spring ephemerals will experience increased light competition because canopy leaf out is more sensitive to warming than is the phenology of spring ...

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Retirement income systems, such as superannuation, are meant to be non‐discriminatory and consider disadvantage faced by members of society. There are significant differences between the life expectancies of Indigenous and non‐Indigenous peoples. The gap in life expectancies is not considered when determining when Indigenous peoples can retire.
