High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State
American Journal of Botany, EarlyView.Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

American Journal of Botany, EarlyView.Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

American Journal of Botany, EarlyView.Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

Success of coastal sage scrub restoration is influenced by local adaptations of shrub species
American Journal of Botany, EarlyView.Abstract Premise Restoring plant communities is increasingly challenging with climate change. While practitioners have traditionally used local seed sources, many are recommending assisted migration, possibly from more extreme environments such as inland rather than coastal environments, for restoration.

Sexual Propagation of Persian Shallot (Allium hirtifolium) Through Manual Pollination and In vitro Ovary Germination [PDF]
Journal of Medicinal Plants and By-products, 2013 For sexual reproduction of Allium hirtifolium, collected bulbs were planted in the field. In order to develop ovary embryo and seed setting, control self-pollination and natural open pollination took placed using honey bees under cages. Ovary development

Evolutionary relationship between organellar DNA inheritance patterns and traits of seed plants
American Journal of Botany, EarlyView.Abstract Premise In plants, organellar DNA is predominantly maternally inherited, but biparental and paternal inheritance have also been observed. Specific mechanisms, such as plastid exclusion during pollen mitosis or genome degradation, ensure maternal inheritance.

American Journal of Botany, EarlyView.Abstract Premise Calls to adopt seed‐sourcing strategies in biological restoration that preserve local adaptation while maximizing genetic variation (e.g., regional admixture provenancing) are increasingly common. Heterosis, the increased fitness of progeny from crosses between populations relative to progeny from crosses within populations, could ...

BarnebyLives: An R package to create herbarium specimen labels and clean spreadsheets
Applications in Plant Sciences, EarlyView.Abstract Premise Accessioning herbarium specimens is labor intensive, yet remains vital for research in ecology, evolution, and conservation. As institutional support for herbaria declines, efficient tools are needed to streamline this process. The R package BarnebyLives was developed to assist collectors by supplementing collection notes, verifying ...
