  2. Pin-point method (ecology) - Wikipedia

    en.wikipedia.org/wiki/Pin-point_method_(ecology)

    The pin-point method (or point-intercept method) is used for non-destructive measurements of plant cover and plant biomass. [1] [2] In a pin-point analysis, a frame (or a transect) with a fixed grid pattern is placed above the vegetation. A pin is inserted vertically through one of the grid points into the vegetation and will typically touch a ...

  3. Biomass partitioning - Wikipedia

    en.wikipedia.org/wiki/Biomass_partitioning

    Biomass partitioning is the process by which plants divide their energy among their leaves, stems, roots, and reproductive parts.These four main components of the plant have important morphological roles: leaves take in CO 2 and energy from the sun to create carbon compounds, stems grow above competitors to reach sunlight, roots absorb water and mineral nutrients from the soil while anchoring ...

  4. Tree allometry - Wikipedia

    en.wikipedia.org/wiki/Tree_allometry

    Stem profile measurement Electronic equipment (as Field-Map for example) is used for stem profile measurements and for measurements of profiles/projections of the crown. These key measurements are used for estimation of carbon sequestered in the plants. Forest structure measurement is needed for establishment of allometric equations.

  5. Biomass (ecology) - Wikipedia

    en.wikipedia.org/wiki/Biomass_(ecology)

    Biomass is the mass of living biological organisms in a given area or ecosystem at a given time. Biomass can refer to species biomass, which is the mass of one or more species, or to community biomass, which is the mass of all species in the community. It can include microorganisms, plants or animals. [3]

  6. Biomass allocation - Wikipedia

    en.wikipedia.org/wiki/Biomass_allocation

    A next level of analysis is to measure the growth allocation: what is the increase in total biomass of a plant, and to what extent is the increase due to growth of leaves, of stems and of roots. In young plants, growth allocation is often quite similar to the actual biomass allocation.

  7. Bioenergy - Wikipedia

    en.wikipedia.org/wiki/Bioenergy

    Bioenergy is a type of renewable energy that is derived from plants and animal waste. [1] The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants. [2] Thus, fossil fuels are not regarded as biomass under this definition.

  8. Biomass (energy) - Wikipedia

    en.wikipedia.org/wiki/Biomass_(energy)

    Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10]

  9. Theoretical production ecology - Wikipedia

    en.wikipedia.org/wiki/Theoretical_production_ecology

    Because an increased biomass implies higher respiration per surface unit and a limited increase in intercepted light, crop growth is a sigmoid function of crop biomass. Plant production distribution – Usually only a fraction of the total plant biomass consists of useful products, e.g. the seeds in pulses and cereals, the tubers in potato and ...
