Water potential gradient, root conduit size and root xylem hydraulic conductivity determine the extent of hydraulic redistribution in temperate trees

Benjamin D Hafner, Benjamin D Hesse, Taryn L Bauerle & Thorsten EE Grams
1. Hydraulic redistribution (HR) of soil water through plant roots is widely described, however its extent, especially in temperate trees, remains unclear. Here, we quantified redistributed water of five temperate tree species. We hypothesized that both, HR within a plant and into the soil increases with higher water-potential gradients, larger root conduit diameters and root-xylem hydraulic conductivities. 2. Saplings of conifer (Picea abies, Pseudotsuga menziesii), diffuse-porous (Acer pseudoplatanus) and ring-porous species (Castanea sativa, Quercus robur)...

Data from: Soil organic carbon stability in forests: distinct effects of tree species identity and traits

Rising atmospheric CO2 concentrations have increased interest in the potential for forest ecosystems and soils to act as carbon (C) sinks. While soil organic C contents often vary with tree species identity, little is known about if, and how, tree species influence the stability of C in soil. Using a 40‐year‐old common garden experiment with replicated plots of eleven temperate tree species, we investigated relationships between soil organic matter (SOM) stability in mineral soils and...

Data from: Frequency and characteristics of MODY 1 (HNF4A mutation) and MODY 5 (HNF1B mutation) - Analysis from the DPV database

Objective. To characterize initial presentation and clinical course of patients with hepatocyte nuclear factor (HNF) 4A- and HNF1B-MODY in a multinational registry. Design, setting and participants. Within the Diabetes Patienten Verlaufsdokumentation (DPV) registry, 44 patients with HNF4A- and 35 patients with HNF1B-MODY were characterized and compared with patients < 20years old with type 1 diabetes (T1D)/type 2 diabetes (T2D). Main outcome measure. Clinical and laboratory parameters, therapy, metabolic control, and extrapancreatic symptoms in patients with...

Data from: Effect of plant chemical variation and mutualistic ants on the local population genetic structure of an aphid herbivore

1.Plants exhibit impressive genetic and chemical diversity, not just between species but also within species, and the importance of plant intraspecific variation for structuring ecological communities is well known. When there is variation at the local population level, this can create a spatially‐heterogeneous habitat for specialized herbivores potentially leading to non‐random distribution of individuals across host‐plants. 2.Plant variation can affect herbivores directly and indirectly via a third species, resulting in variable herbivore growth rates across...
