A simple protocol for producing axenic seeds of Sorghum bicolor Open
Microbes within seeds can confound research on microbial colonization, symbiosis, and pathogenesis. Sterilization of both external and internal seed tissues is therefore essential in certain experiments, but the method must also preserve s…

Plasticity in Hydraulic Architecture: Riparian Trees Respond to Increased Temperatures With Genotype‐Specific Adjustments to Leaf Traits Open
Climate means and variability are shifting rapidly, leading to mismatches between climate and locally adapted plant traits. Phenotypic plasticity, the ability of a plant to respond to environmental conditions within a lifetime, may provide…

Hyperspectral Leaf Reflectance Detects Interactive Genetic and Environmental Effects on Tree Phenotypes, Enabling Large‐Scale Monitoring and Restoration Planning Under Climate Change Open
Plants respond to rapid environmental change in ways that depend on both their genetic identity and their phenotypic plasticity, impacting their survival as well as associated ecosystems. However, genetic and environmental effects on pheno…

Better utilization of inorganic nitrogen compared to organic nitrogen by a plant symbiotic fungal isolate of Alternaria alternata Open
Alternaria alternata, a fungus that causes plant diseases, is also a Dark Septate Endophyte (DSE) that can enhance host plant growth by improving access to soil nutrients like nitrogen. To test the environmental factors influencing …

Intensive leaf cooling promotes tree survival during a record heatwave Open
Increasing heatwaves are threatening forest ecosystems globally. Leaf thermal regulation and tolerance are important for plant survival during heatwaves, though the interaction between these processes and water availability is unclear. Gen…

The Relationship Between Maturation Size and Maximum Tree Size From Tropical to Boreal Climates Open
The fundamental trade‐off between current and future reproduction has long been considered to result in a tendency for species that can grow large to begin reproduction at a larger size. Due to the prolonged time required to reach maturity…

Variation of root functional traits indicates flexible below‐ground economic strategies of the riparian tree species <i>Populus fremontii</i> Open
Plant‐mycorrhizal type has been suggested as an integrator of plant functional traits, yet most of what is known about these relationships comes from studies of different plant taxa, where the effects of mycorrhizal type cannot be isolated…

Utilizing symbiotic relationships and assisted migration in restoration to cope with multiple stressors, and the legacy of invasive species Open
Introduction Climate change has increased the need for forest restoration, but low planting success and limited availability of planting materials hamper these efforts. Invasive plants and their soil legacies can further reduce restoration…

Microevolutionary Processes in a Foundation Tree Inform Macrosystem Patterns of Community Biodiversity and Structure Open
Despite an increased focus on multiscale relationships and interdisciplinary integration, few macroecological studies consider the contribution of genetic-based processes to landscape-scale patterns. We test the hypothesis that tree geneti…

Linking seed size and number to trait syndromes in trees Open
Aim Our understanding of the mechanisms that maintain forest diversity under changing climate can benefit from knowledge about traits that are closely linked to fitness. We tested whether the link between traits and seed number and seed si…

Sequential hybridization may have facilitated ecological transitions in the Southwestern pinyon pine syngameon Open
Summary Multispecies interbreeding networks, or syngameons, have been increasingly reported in natural systems. However, the formation, structure, and maintenance of syngameons have received little attention. Through gene flow, syngameons …

The effect of natural disturbances on forest biodiversity: an ecological synthesis Open
Disturbances alter biodiversity via their specific characteristics, including severity and extent in the landscape, which act at different temporal and spatial scales. Biodiversity response to disturbance also depends on the community char…

Evidence of climate-driven selection on both tree traits and trait plasticity across the climatic range of a riparian foundation species Open
Selection on quantitative traits by divergent climatic conditions can lead to substantial trait variation across a species range. In the context of rapidly changing environments, however, it is equally important to understand selection on …
