Seedling survival in a giant sequoia forest

California Agriculture, 1969
Fire in seedbed preparation (including ash from burning debris), appears to be essential for giant sequoia seedling survival, and was beneficial to survival of white fir seedlings in these tests at Whitaker's Forest, Tulare County.

Increased seed survival and seedling emergence in a polyploid plant invader [PDF]

American Journal of Botany, 2013
• Premise of the study: Because seeds have essential functions in the life cycle of plants, even subtle changes in their characteristics may have important demographic consequences. In this study, we examined whether potential changes in seed characteristics as a result of polyploidy or postintroduction evolution may have contributed to the invasion of

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.

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

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 ...

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.

Sympatric Fagaceae Segregate Rodent Scatter-Hoarding Services for Similar Seed Dispersal Effectiveness in a Subtropical Forest in China

Animals
In forest ecosystems where seed dispersal is predominantly mediated by scatter-hoarding rodents, sympatric plants compete for these limited dispersal services.

Edge Effects on Seedling Diversity Are Mediated by Impacts of Fungi and Insects on Seedling Recruitment but Not Survival [PDF]

Frontiers in Forests and Global Change, 2019
La creciente conciencia del papel de los enemigos en la dinámica de la comunidad vegetal ha llevado a los ecologistas a explorar cómo cambian las interacciones planta-enemigo en los sistemas modificados por el hombre. Se descubrió que la proximidad a los bordes del bosque debilita el papel de dos grupos de enemigos de las plantas, los herbívoros de ...

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.
