Maximum water stress is decoupled from climate, traits and growth in a xeric oak Open
Summary Widespread drought-induced forest mortality highlights the ecological consequences of climate change, yet our ability to explain, let alone predict, the spatial patterns of forest mortality remains limited. We conducted a range-wid…

Plasticity, geographic variation and trait coordination in blue oak drought physiology Open
Summary Our ability to predict drought stress across the landscape remains limited. This uncertainty stems in part from an incomplete understanding of within-species variation in hydraulic physiology, particularly coordinated variation acr…

PARTITIONING GENETIC AND ENVIRONMENTAL COMPONENTS OF PHENOLOGICAL VARIATION IN QUERCUS DOUGLASII (FAGACEAE) Open
Oaks (genus Quercus) often display a large range of phenotypic variation across many of their traits. The contribution of genetic and environmental sources, and their interaction, to this variation can be partitioned experimentally using c…

Evolutionary relationships between drought-related traits and climate shape large hydraulic safety margins in western North American oaks Open
Significance A fundamental association between sustained water transport and downstream tissue survival should select for xylem that avoids embolism in long-lived woody plants. Previous studies suggest that long-vessel species, such as oak…

Topoclimates, refugia, and biotic responses to climate change Open
Plant distributions are strongly influenced by both climate and topography. In an analysis of geographic and topographic distributions for selected tree species in California, we found that tree populations are increasingly restricted to e…

No local adaptation in leaf or stem xylem vulnerability to embolism, but consistent vulnerability segmentation in a North American oak Open
Summary Vulnerability to embolism varies between con‐generic species distributed along aridity gradients, yet little is known about intraspecific variation and its drivers. Even less is known about intraspecific variation in tissues other …
