Root biomass allocation in the world's upland forests
Oecologia, 1997Because the world's forests play a major role in regulating nutrient and carbon cycles, there is much interest in estimating their biomass. Estimates of aboveground biomass based on well-established methods are relatively abundant; estimates of root biomass based on standard methods are much less common.

Variation and Plasticity of Biomass Allocation in Daphnia
Functional Ecology, 19941. For organisms with indeterminate growth a trade-off between growth and reproduction is expected. The detection of this trade-off depends not only on the covariance between these two traits, but also on the variation of their sum, the total production (TP = growth + reproduction).

Patterns of fucoid reproductive biomass allocation
British Phycological Journal, 1992The reproductive biomass allocation patterns (i.e. total reproductive effort) for eight perennial Northwest Atlantic fucoid algae (Ascophyllum nodosum, A. nodosum ecad scorpioides, Fucus distichus ssp. anceps, F. d. distichus, F. d. edentatus, F. d. evanescens, F. spiralis and F.

Biomass and nutrient allocation in a neotropical dioecious palm
Oecologia, 1984The sexes of Chamaedorea ernesti-augusti are largely undifferentiated in the distribution of biomass, nitrogen, phosphorus, potassium, and total non-structural carbohydrates, among leaves and stems. Males bear more inflorescences that are cheaper except in nitrogen, but most females bear greater annual energetic and nutritional burdens due to seed ...

Allelochemic control of biomass allocation in interacting shrub species
Journal of Chemical Ecology, 1993Aqueous leachates derived from canopy phyllodes of invasiveAcacia cyclops affected growth of a range of shrub species independently of nutrient input effects. All plants showed a sublethal phytotoxic response. Root mass was generally less adversely affected than shoot mass and, while decreasing significantly in response to the 10% concentration, showed

Plant Root-Shoot Biomass Allocation Over Diverse Biomes: A Global Synthesis
Global Ecology and Conservation, 2019 Globally, the allocation of root-shoot biomass is a key plant-adaptive strategy for terrestrial ecosystems to enhance carbon-sequestration capacity. However, the deep mechanisms of above-/below-ground biomass distribution remain unclear, partly due to ...

Reproductive biomass allocation in three Sargassum species
Oecologia, 1985Allocation of biomass to sexual reproductive (receptacle) tissue and vegetative (holdfast) tissue differed absolutely and relatively in three Sargassum species that form the bulk of the intertidal algal canopy in the northern Gulf of California. Sargassum herporhizum devoted a greater proportion of its thallus mass into its rhizoidal holdfast than did ...

BIOMASS ALLOCATION IN AN AGROPYRON SMITHII‐GLOMUS SYMBIOSIS
American Journal of Botany, 1987The type of response the steppe grass Agropyron smithii Rydb. exhibits to mycorrhizal fungi is dependent upon where along the resource gradient the experiment is conducted. At the lower end of a soil‐phosphorus (P) gradient (2 μg P g ‐1 soil ...

On the Comparative Allocations of Biomass, Energy, and Nutrients in Plants
Ecology, 1982The objective of this study was to test the assumption that biomass allocation, energy allocation, and nutrient element allocation are equivalent for studies involving ecological—strategy analysis in plants. The results for the semelparous Verbascum thapsus and five iteroparous Solidago species show that the mineral elements examined are allocated ...

Resource capture, biomass allocation and growth in herbaceous plants
Trends in Ecology & Evolution, 1991Plant species differ widely in their rate of biomass production, even when grown under optimal conditions. A key question concerns the extent to which these growth rates correlate with the uptake of carbon and nitrogen and with the biomass allocation between leaves and roots.
