Understanding and predicting ecosystem functioning (e.g., carbon and water fluxes) and the role of soils in carbon storage requires an accurate assessment of plant rooting distributions. Here, in a comprehensive literature synthesis, we analyze rooting patterns for terrestrial biomes and compare distributions for various plant functional groups. We compiled a database of 250 root studies, subdividing suitable results into 11 biomes, and fitted the depth coefficient β to the data for each biome… Expand
Studies in global plant biogeography have almost exclusively analyzed re- lationships of abiotic and biotic factors with the distribution and structure of vegetation aboveground. The goal of thisExpand
New model to predict rooting in diverse plant community compositions
Abstract A modelling approach based on generally valid geometrical formulas and simple statistical procedures is presented with the aim of predicting the total rooting density and rootingExpand
Plant rooting strategies in water-limited ecosystems
[1] Root depth and distribution are vital components of a plant's strategy for growth and survival in water-limited ecosystems and play significant roles in hydrologic and biogeochemical cycling.Expand
Root distribution by depth for temperate agricultural crops
The estimated root distribution patterns from the present study could be incorporated into agroecosystem models for good representations of belowground processes and enhance the accuracy of carbon and water cycling estimation in agroECosystem. Expand
Root distribution and soil moisture retrieval in perennial and annual energy crops in Northern Italy
Abstract This study focused on root size and distribution of energy crops which may be a reliable indicator of the capability of these crops to accumulate significant C stocks in the soil. Alike,Expand
Describing the vertical root distribution of alpine plants with simple climate, soil, and plant attributes
Abstract The vertical root distribution (VRD) in the soil remains unknown for most plant species, as studying root systems in different pedo-climatic settings is time-consuming and methodologicallyExpand

Incorporation of a dynamic root distribution into CLM4.5: Evaluation of carbon and water fluxes over the Amazon
Roots are responsible for the uptake of water and nutrients by plants and have the plasticity to dynamically respond to different environmental conditions. However, most land surface models currentlyExpand
Factors causing variation in fine root biomass in forest ecosystems
Abstract Fine roots form one of the most significant components contributing to carbon cycling in forest ecosystems. We study here the effect of variation in root diameter classes, sampling depth andExpand


Spatial Distributions of Grass and Shrub Root Systems in the Shortgrass Steppe
In water-limited ecosystems such as the shortgrass steppe of North America, the ability of plants to absorb sufficient water for growth and reproduction is dependent upon the characteristics of theirExpand
Maximum rooting depth of vegetation types at the global scale
Deep root habits are quite common in woody and herbaceous species across most of the terrestrial biomes, far deeper than the traditional view has held up to now, and has important implications for a better understanding of ecosystem function and its application in developing ecosystem models.

SummaryFine roots and mycorrhizae have recently been shown to produce a major portion of the organic matter entering decomposition. Roots and mycorrhizae constitute 63 to 70% of total net primaryExpand
Root Production and Root Turnover in a Wet Tundra Ecosystem, Barrow, Alaska
The wet tundra near Barrow, Alaska, is dominated by three species of graminoids: Dupontia fischeri, Carex aquatilis, and Eriophorum angustifolium, each species having a distinctive pattern and phenology. Expand
Patterns of fine root mortality in two sugar maple forests
It is reported here that roots in the northern forest consistently lived the longest, principally owing to greater rates of mortality early in the life of roots at the southern site, and differences in site factors suggest that warmer soil temperatures seem to be associated with the more rapid death of Roots at theSouthern site.

Soil-Root Relationships of Certain Native Grasses in Various Soil Types
A new method has been devised which consists of obtaining representative samples of entire root systems, of studying the intimate relations of roots and soils, and of measuring root production quantitatively at various soil levels. Expand

Fine-root biomass and soil properties in a semideciduous and a lower montane rain forest in Panama
The hypothesis that a largeRoot biomass in montane forests is related to nutrients in low concentration and diluted in organic soils with high CEC and low bulk density is supported, and that fine root biomass in tropical forests in inversely related to calcium availability but not a phosphorus as has been suggested for other forests.
