We then test the primary prediction of the model – that host range should be negatively correlated with host abundance – by examining the ecological and evolutionary dynamics of phage populations in laboratory microcosms maintained at host densities above and below this threshold.
The alternative business models that can host the application are presented and related to the model's dimensions.
At best, semi-educated guesses, pulled out of models that make a host of assumptions over what the post-Brexit future holds.
Those authors argued that virus competition and evolution within small subpopulations of rabbits was the most likely scenario in Europe, but they also explored models that assumed infinite host populations and high connectivity between subpopulations.
Japan, for its part, is a model ally that hosts a large U.S. troop presence and makes multi-billion dollar payments to offset the costs of stationing these forces on its soil in what is by far the most generous host nation support provided by any of America's 27 allies.
We have previously presented a theoretical model that includes host fitness relationships with inbreeding and outbreeding, and the way in which genotypic variation may affect the expression of the endophyte mutualistic effect on the grass in terms of persistence and productivity (Gundel et al. 2010).
This effect is analogous to that in evolutionary models that examine how exploitation host strategies influence parasite virulence [32].
Electroporation of uninfected erythrocytes in the presence of ALA, however, resulted in robust intracellular porphyrin fluorescence, supporting our model that host enzymes have latent biosynthetic activity that requires a mechanism for ALA uptake across the normally impermeable erythrocyte membrane.
However, as population sequencing becomes common, there is a need for additional models that consider the role of host TE regulation and mating system.
In an attempt to establish quantifiable relationships among these essential components of human endotoxemia we have proposed the development of deterministic, semi-mechanistic based host response models that include transcriptional dynamics, signaling and physiological components for the modulation of the response [33], [34].
