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.

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.

Exposure to heat waves and drought improves subsequent leaf heat tolerance for five oak species in southern California

American Journal of Botany, EarlyView.
Abstract Premise Given the threats of climate change, we investigated the impact of high temperatures separately and in combination with reduced soil water on leaf heat tolerance for five oaks (Fagaceae) with overlapping ranges in southern California, USA: Quercus agrifolia and Q. chrysolepis (evergreen species), Q. douglasii and Q.

Placing very long branch taxa in the plant tree of life: A case study with Dioscoreales mycoheterotrophs

American Journal of Botany, EarlyView.
Abstract Premise The inclusion of heterotrophic plants in broader systematic studies is challenging due to substantial morphological modification, gene loss, and accelerated substitution rates following photosynthesis loss. In particular, inclusion of very long branch (VLB) taxa with highly elevated rates may lead to phylogenomic misinference.

Palatability of geophyte underground storage organs partially explains their depth in the Cape Floristic Region, geophyte capital of the world

American Journal of Botany, EarlyView.
Abstract Premise The soil depth of underground storage organs (USOs) of geophytes involves cost–benefit trade‐offs and may relate to USO age, size, and disturbances such as fire and herbivory. Yet determinants of USO depth are poorly studied. We posit that belowground mammalian predation of USOs is a selective force for the positive relationship ...

Heterosis in crosses between remnant populations of the rare prairie forb Silene regia: Implications for restoration genetics

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 ...

The challenge for botanic garden science [PDF]

PLANTS, PEOPLE, PLANET, 2018
Societal Impact StatementPlants are fundamental to solving many of humanity's most important challenges: food insecurity, water scarcity, energy, health, and climate change. With more than 20% of the world's plant species currently threatened with extinction, the loss of plant diversity will result in reduced options for human innovation, adaptation ...
