However, when exposed to stress, Mtb has the ability to switch phenotype to a non-replicating form suitable for persistence (Deb et al., 2009).
An initial study [ 7] suggested that the tested XML database configurations without further optimizations were not suitable as persistence mechanisms for openEHR-based systems in production if population-wide ad hoc querying was needed.
Natural barriers and other factors may also accidentally obstruct the dispersal of marmots, vector fleas, or Y. pestis into the certain areas where habitats are suitable for persistence of natural foci.
Conditions over most of southern Australia appear to have remained suitable for population persistence, allowing endemic lineages of these lizards to persist.
The concentration effects are not significant for the more flexible PHF, and viscometry data are suitable for determining persistence lengths, even by linear approximation methods that use the ratio of intrinsic viscosity and molar mass.
Outputs from the spatial MCDA indicate that large areas of sub-Saharan Africa may be suitable for ASF persistence as part of either domestic or sylvatic transmission cycles.
A practical way to estimate the geographic distribution of a species is by characterizing the environmental conditions that are currently suitable for its persistence [ 49] and then identifying those areas where such conditions may be found [ 50].
It may be that harsher conditions in which there are very ephemeral moments of soil moisture creates higher levels of endemism of bdelloids, whereas environments in which soil moisture is sustained for longer periods of time allow for increased chances of long distance dispersal to suitable habitats and persistence.
Management practices that preserve dense stands of snags will promote the longer-term persistence of suitable snags as nesting habitat for cavity-nesting birds.
However, we find that in landscapes that offer fewer suitable sites for egg persistence (i.e., high sensitivity to local landscape characteristics), our model predicts greater variability in parasite prevalence among host groups, and a shift to source-sink parasite dynamics.
