Hydrologic regulation of plant rooting depth.
Plant rooting depth affects ecosystem resilience to environmental stress such as drought. Deep roots connect deep soil/groundwater to the atmosphere, thus influencing the hydrologic cycle and climate. Deep roots enhance bedrock weathering, thus regulating the long-term carbon cycle. However, we know little about how deep roots go and why. Here, we present a global synthesis of 2,200 root observ...
متن کاملEcosystem rooting depth determined with caves and DNA.
Belowground vertical community composition and maximum rooting depth of the Edwards Plateau of central Texas were determined by using DNA sequence variation to identify roots from caves 5-65 m deep. Roots from caves were identified by comparing their DNA sequences for the internal transcribed spacer (ITS) region of the 18S-26S ribosomal DNA repeat against a reference ITS database developed for ...
متن کاملHalfspace Depth and Regression Depth Characterize the empirical Distribution
For multivariate data, the halfspace depth function can be seen as a natural and affine equivariant generalization of the univariate empirical cdf. For any multivariate data set, we show that the resulting halfspace depth function completely determines the empirical distribution. We do this by actually reconstructing the data points from the depth contours. The data need not be in general posit...
متن کاملRooting depth explains [CO2] x drought interaction in Eucalyptus saligna.
Elevated atmospheric [CO(2)] (eC(a)) often decreases stomatal conductance, which may delay the start of drought, as well as alleviate the effect of dry soil on plant water use and carbon uptake. We studied the interaction between drought and eC(a) in a whole-tree chamber experiment with Eucalyptus saligna. Trees were grown for 18 months in their C(a) treatments before a 4-month dry-down. Trees ...
متن کاملDepth Distribution in High Dimensions
Motivated by the analysis of range queries in databases, we introduce the computation of the Depth Distribution of a set B of axis aligned boxes, whose computation generalizes that of the Klee’s Measure and of the Maximum Depth. In the worst case over instances of fixed input size n, we describe an algorithm of complexity within O(n d+1 2 logn), using space within O(n logn), mixing two techniqu...
