چکیده

If a population is growing in a randomly varying environment, such that the finite rate of increase per generation is a random variable with no serial autocorrelation, the logarithm of population size at any time t is normally distributed. Even though the expectation of population size may grow infinitely large with time, the probability of extinction may approach unity, owing to the difference between the geometric and arithmetic mean growth rates.

Effect of Varying Protein Levels and Preservation Methods and Duration on Egg Production Performance and External Egg Qualities of Japanese Quails in a Semi-Arid Environment

The study was conducted to determine the effect of varying protein levels and preservation method on external egg qualities of Japanese quails. A total of 180 birds were randomly allotted into three dietary treatments in a completely randomized design (CRD) replicated six times. A factorial arrangement of 3 × 4 × 4 which involves 3 protein levels (15, 20 and 25% crude protein), 4 storage method...

ESS germination strategies in randomly varying environments. I. Logistic-type models.

ESS germination strategies are studied in a model of annual plant population dynamics in a randomly varying environment. The possible strategies are different values of the annual germination fraction G, either constant over time or varying in response to a "cue" correlated with upcoming environmental conditions. The model generalizes D. Cohen's model (1966, J. Theor. Biol. 12, 119-129; 1968, J...

Time under Tension of muscle is one of the variables of strength training that contributes to its adaptation. The present study was conducted the effects of six weeks of resistance training with the varying Time under Tension of muscle on VEGF and endosotene serum levels  in healthy young women. This study was conducted on 20 female students (22.65±2.03years) Subjects were randomly and equally ...

Stochastic gene expression in switching environments.

Organisms are known to adapt to regularly varying environments. However, in most cases, the fluctuations of the environment are irregular and stochastic, alternating between favorable and unfavorable regimes, so that cells must cope with an uncertain future. A possible response is population diversification. We assume here that the cell population is divided into two groups, corresponding to tw...

Population Growth in a Random Environment: Which Stochastic Calculus?

Let N = N(t) be the size (number of individuals, density, biomass) of a population (of animals, plants, bacteria, cells) at time t ≥ 0 and assume the initial population size N(0) = N0 > 0 is known. A general density dependent growth model assumes that the per capita growth rate (abbrev. growth rate) has the form 1 N dN dt = f(N), where f(·) : (0,+∞) 7→ (−∞,+∞) is a continuously differentiable f...
