Sentence examples for environment fluctuation from inspiring English sources

The environment fluctuation provokes a great decline in the population without really menacing it.

Moreover, an environment fluctuation in our model is similar to a winter season for Daphnia.

This is not the situation in a standard simulation because when an environment fluctuation occurs the stabilization phase does not start necessarily with all unfit genotypes.

We see that a long stability period, π = 50, allows the population with 50% of asexuality to outcompete the other one by completing both the generation and amplification phases before the environment fluctuation.

Moreover, zooplankton communities are sensitive to anthropogenic impacts and their study may be useful in the prediction of long-term changes in lake ecosystems, as these communities are highly sensitive to environment fluctuations (Ferrara, Vagaggini, & Margaritora, 2002; Jeppesen et al., 2011; Kehayias, Chalkia, & Doulka, 2014; Preston & Rusak, 2010).

Gene regulation is an intrinsically noisy process, which is subject to intracellular and extracellular noise perturbations and environment fluctuations [ 8- 14] 14].

Because we want to study the influence of environment fluctuations on the populations with respect to their kind of reproduction, we found that μ = 0.2 gives understandable results.

The noise perturbations in the model can arise both intracellularly, due to the intrinsically noisy property of the gene regulation process, and extracellularly, due to environment fluctuations.

In particular, a greater percentage of sexual reproduction is advantageous either when the environment fluctuations are frequent or when the selection is strong, but it is disadvantageous either in a stable environment or in presence of mild selection.

Thus, our model can approximate the behaviour of a population with cyclical parthenogenesis by representing the length of the parthenogenetic phase with the percentage of asexual reproduction, and the diapause periods with environment fluctuations.

In the marine environment, fluctuations in sea level, water temperatures and sea ice caused by glacial cycles are believed to have had a major influence on species distributions and the population connectivity of marine species [ 1- 3].
