Throughout the time series, national harvest disturbance rates varied between one and two percent, and were largely a function of harvest in the more heavily forested regions of the US (Mountain West, Northeast, and Southeast).
See Table 1 for a list of population parameter values, and Figures 1 and prior literature [12], [43] for the per recruit egg production and harvest-per-recruit as a function of harvest rate.
The objectives of this research were to explore the changes in the low back biomechanical responses during a harvesting task as a function of different harvesting techniques/postures and to explore the effects of an ergonomic intervention designed to reduce the low back stress during this work activity.
Fig. 4 The average transmit power as a function of the harvest energy threshold.
We evaluated these statements using information theory to compare models of population growth as a function of human harvest, for NRM wolves and other populations (Table 3).
On the other hand, the fitted age-at-harvest models resulted in a highly non-linear relationship as a function of age, with harvest rates of 2-year-old bears higher than those of yearlings, a decrease in harvest rates from age 2 through age 7, and then increasing harvest rates from age 7 to age 10+ (Figure 6D).
The population's abundance as a function of the maximal harvest probability is higher for poor than for normal freshwater survival conditions, whereas for good conditions, a nonmonotonic dependence on maximal harvest probability is found (Fig. 4E).
For each forest type (or plant functional type, as we grouped the data in this analysis), data describing its NEP response as a function of time since harvest was also needed.
For example, Equation 2 describes the annual change in the amount of wood C in single family homes (In-useSFH) as a function of the annual harvest input, the flow of C through the mills, into primary products and into the single family home pool, minus the amount of C retired from use.
Fluctuating levels of PA contamination in the consumer food supply, especially via certain herbal teas (e.g., comfrey), honey (Beales et al. 2004), dairy products, beef, and grains, are a function of drought and harvest or foraging conditions, and therefore exhibit aperiodic cycles of high expression.
