Consistency between an allometric approach and optimal partitioning theory in global patterns of plant biomass allocation [PDF]

Functional Ecology, 2007
Summary Optimal partitioning theory (OPT) suggests that plants should allocate biomass to the organ that acquires the most limiting resource. An implied assumption of this is that there are trade‐offs in allocation between leaf, stem and root functions.

Biomass allocation between reproductive and vegetative organs of Artemisia along a large environmental gradient [PDF]

BMC Plant Biology
Background Biomass allocation reflects functional tradeoffs among plant organs and thus represents life history strategies. However, little is known about the patterns and drivers of biomass allocation between reproductive and vegetative organs along ...

Contrasting allocation patterns in wheat and weeds: allometric belowground and reproductive investment versus optimal partitioning adaptations [PDF]

Frontiers in Plant Science
IntroductionModeling differences in biomass allocation between wheat and weeds—specifically to shoots (aboveground biomass), roots (belowground biomass), and seed mass (reproductive biomass)—enhances our understanding of sustainable weeds management ...

Biomass, Carbon and Nitrogen Partitioning and Water Use Efficiency Differences of Five Types of Alpine Grasslands in the Northern Tibetan Plateau. [PDF]

Int J Environ Res Public Health, 2022
(1) Background: Grassland covers most areas of the northern Tibetan Plateau along with important global terrestrial carbon (C) and nitrogen (N) pools, so there is a need to better understand the different alpine grassland growth associated with ecosystem

Biomass partitioning of plants under soil pollution stress. [PDF]

Commun Biol, 2022
Polluted sites are ubiquitous worldwide but how plant partition their biomass between different organs in this context is unclear. Here, we identified three possible drivers of biomass partitioning in our controlled study along pollution gradients: plant

Trade-Offs and Partitioning Strategy of Carbon Source-Sink During Fruit Development of Camellia oleifera [PDF]

Plants
Non-structural carbohydrates (NSCs), the main substrates and energy carriers of plants, play an important role in mediating the source-sink balance of carbon (C).

Confronting allometric and optimal partitioning theories in biomass allocation: evidence from Artemisia species along an elevational gradient in Southwest of China

Journal Of Plant Ecology
Abstract The allometric partitioning theory (APT) and optimal partitioning theory (OPT) emphasize the roles of plant size and resource constraints in shaping the adaptive strategies of plants growing under diverse environmental conditions.

An allometric prior enhances acoustic niche partitioning signal

Journal of the Royal Society Interface, 2022
The acoustic niche hypothesis suggests that vocal signals of sympatric animal species are structured so as to minimize acoustic interference and facilitate communication.

Allometric biomass partitioning under nitrogen enrichment: Evidence from manipulative experiments around the world

Scientific Reports, 2016
Allometric and optimal hypotheses have been widely used to explain biomass partitioning in response to resource changes for individual plants; however, little evidence has been reported from measurements at the community level across a broad geographic ...
