. Using herbarium specimens spanning 133 years and field-collected measurements, we assessed intraspecific trait (leaf structural stomatal) variability from grass species in the Great Plains of North America. We focused on two widespread, closely related grasses tribe Paniceae:

Woody Encroachment Modifies Subsurface Structure and Hydrological Function

ABSTRACT Woody encroachment—the expansion of woody shrubs into grasslands—is a widely documented phenomenon with global significance for the water cycle. However, its effects on watershed hydrology, including streamflow and groundwater recharge, remain poorly understood. A key challenge is limited understanding how changes to root abundance, size distribution across soil depths influence infiltration preferential flow. We hypothesised that would increase deepen coarse‐root abundance effective porosity, thus promoting deeper increasing flow velocities. To test this hypothesis, we conducted study at Konza Prairie Biological Station in Kansas, where roughleaf dogwood ( Cornus drummondii ) predominant shrub encroaching native tallgrass prairie. quantified coarse fine roots leveraged moisture time series electrical resistivity imaging analyse beneath grasses. observed greater fraction compared grasses, which was concurrent saturated hydraulic conductivity porosity. Half‐hourly rainfall data show average through macropores 135% than grasses deepest B horizon, consistent conductivity. Soil‐moisture also indicated large events antecedent wetness promoted more layers These findings suggest encroachment alters hydrologic processes cascading consequences ecohydrological processes, increased vertical connectivity potential recharge.
