Sentence examples for rate of resource use from inspiring English sources

Both of these models show that the rate of resource use per unit area is independent of plant size, although both models assume different allometric exponents.

The decline in leaf mass per individual with increasing density results in a decrease in the rate of resource use and the allometric exponent β (Fig. 5).

Assuming that the rate of resource use per unit leaf biomass, Ki, is constant in the same plant type (where i represents the different plant types or environmental conditions), we can generate the equation: Q = ML×Ki∝ML.

The rate of biomass production, however, may not adequately reflect the metabolic rate or the rate of resource use because growth rates only provide estimates of an organism's net assimilation, and exclude any dissimilation energy.

Enqusit et al. [9] extended the energetic equivalence rule from mammal populations to plant populations based on the WBE theory, R = NmaxQ∝M3/4M−3/4 = M0, where R is the rate of resource use per unit area; Nmax is the maximum population density; Q is the average rate of resource use or the metabolic rate per individual; and M is the average individual mass.

If the allometric exponent of the average rate of resource use per individual Q vs. plant mass is β, i.e. Q∝Mβ (where β is variable), according to the general model of energy equivalence, R = NmaxQ∝M0, the relationship between population density and plant mass should theoretically follow the model: Nmax∝Mδ, where δ = -β or δ/β = −1.

There is abundant evidence that the current rates of resource use are unsustainable, both in terms of their long-term availability (such as in fisheries and fossil fuels) or impacts (climate).

For example, some models suggest that competition among cancer cells resulting in resource overuse may contribute to invasion and metastasis, just as high rates of resource use lead to dispersal of organisms (Aktipis et al. 2011).

For example, rates of resource use were derived from a range of sources including: analysis of patient records or an observed sample, patient responses to surveys and national and insurance databases, with each of these methods having their own limitations.

In the case of heterotrophic microorganisms, the existence of a dilemma between selfish and cooperative strategies has been proposed to result from a metabolic trade-off between the rate and efficiency of resource use [ 5, 6].

These include overestimating the number and rates of admission and readmission, and underestimating mortality rates and measures of resource use, such as length-of-stay (LOS).
