Using a spatially explicit simulation model, we studied the effect of the surrounding landscape of a protected area on the density and persistence of a predator population inhabiting inside the reserve in different conditions of environmental variability.
Under conditions of low variability, we would expect the probability for symmetric division to undergo selection for a longer period of time before reaching the mutation selection equilibrium.
The fields of resilience engineering and high reliability organising both seek to explain the key sources and characteristics of safety in organisations that operate under conditions of considerable complexity, variability and surprise.
Therefore, design and operation practices should evolve in order to be able to cope with performance uncertainty determined, for example, by evolution of climate conditions, variability of behavioural patterns and performance degradation of technological components.
Trajectory of primary macro-economic issues that are related to reporting the data for international comparisons are completed with third constitutive level – this is conditioned by variability of components that form the definitions of procedures, which are used in a process of data collection of surgical procedures.
Monte Carlo tests are in some conditions conducted to illustrate the effect of variability across different conditions.
Up through the reproductive ages, s x is more sensitive to changes in α3 than to changes in α1, indicating the importance of overall mortality conditions to the pattern of variability in lifespans.
If, in the more constrained conditions, the variability of only a small proportion of the reactions is decreased, the effect on the average would be very small, even when those rates were affected in a large extent.
Although most studies have focused on multimetric indices such as West Virginia Stream Condition Index, similar levels of variability are also present for individual metrics (e.g. see Timpano 2011).
These conditions, despite the variability of the clinical manifestations, may share common pathophysiologic mechanisms.
Environmental effects and changes in operational conditions are the main sources of variability in the structural response.
