This variable indicates the rate of biomass increase per unit leaf area, with typical values ranging from 5-15 g.m −2.day −1 for herbaceous species and 1-5 g.m −2.day −1 for woody seedlings. Although the ULR is not equal to the rate of photosynthesis per unit leaf area, both values are often well correlated.
A rank abundance curve or Whittaker plot is a chart used by ecologists to display relative species abundance, a component of biodiversity. It can also be used to visualize species richness and species evenness. It overcomes the shortcomings of biodiversity indices that cannot display the relative role different variables played in their ...
However, they are also highly relevant in ecology. [4] In general, the total above-ground biomass of a monostand increases with increasing density, up to the point where the biomass saturates. This is what has been dubbed 'constant final yield', [ 5 ] and refers to the total plant biomass per unit ground area.
Figure 1: A bi-phasic bacterial growth curve.. A growth curve is an empirical model of the evolution of a quantity over time. Growth curves are widely used in biology for quantities such as population size or biomass (in population ecology and demography, for population growth analysis), individual body height or biomass (in physiology, for growth analysis of individuals).
Biological exponential growth is the unrestricted growth of a population of organisms, occurring when resources in its habitat are unlimited. [1] Most commonly apparent in species that reproduce quickly and asexually , like bacteria , exponential growth is intuitive from the fact that each organism can divide and produce two copies of itself.
Procter & Gamble (NYSE: PG) is going to try to deflect activist efforts with its earnings report, although the growth here still seems anemic. The consumer products giant reported that core ...
Dividends are distributions from companies to shareholders. Although some companies pay dividends in shares of their stock, traditional dividends are distributed in cash, often quarterly. For...
The Leslie matrix is a discrete, age-structured model of population growth that is very popular in population ecology named after Patrick H. Leslie. [1] [2] The Leslie matrix (also called the Leslie model) is one of the most well-known ways to describe the growth of populations (and their projected age distribution), in which a population is closed to migration, growing in an unlimited ...
