Tree biomass allocation differs by mycorrhizal association

Ecology, 2022
AbstractTree biomass allocation to leaves, roots, and wood affects the residence time of carbon in forests, with potentially dramatic implications for ecosystem carbon storage. However, drivers of tree biomass allocation remain poorly quantified. Using a combination of global data sets, we tested the relative importance of climate, leaf habit, and tree

The Influence of Plant Nutrition on Biomass Allocation

Ecological Applications, 1991
The influence of nutrition on the allocation of dry matter is investigated using data from previously published experiments with the forest tree species (Betula pendular Roth., Picea babies (L.) Karst., Pinus contorta Doug., and Pinus Sibbaldia L.) where the nutrient status of the plants was maintained constant over a considerable period of time and ...

Biomass and its allocation of Chinese forest ecosystems [PDF]

Ecology, 2014
Forest biomass and its allocation have long been considered important in forest ecosystem structure and function. However, discrete forest biomass data and its allocation to various forest components must be standardized to explore many ecological questions, e.g., plant allometric scaling laws, biomass allocation theory, and terrestrial carbon cycling.

Biomass allocation in hermaphrodite flowers

Canadian Journal of Botany, 1982
Patterns of dry matter distribution to male and female organs and to ancillary floral organs were examined in five angiosperm species with hermaphrodite flowers (Lilium superbum, Hibiscus trionum, Podophyllum peltatum, Trillium grandiflorum, and Erythronium albidum).

Root biomass allocation in the world's upland forests

Oecologia, 1997
Because 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.

Patterns of fucoid reproductive biomass allocation

British Phycological Journal, 1992
The 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.

Variation and Plasticity of Biomass Allocation in Daphnia

Functional Ecology, 1994
1. 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).

Biomass and nutrient allocation in a neotropical dioecious palm

Oecologia, 1984
The 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 ...

Reproductive biomass allocation in three Sargassum species

Oecologia, 1985
Allocation 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 ...

Allelochemic control of biomass allocation in interacting shrub species

Journal of Chemical Ecology, 1993
Aqueous 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
