However, host-pathogen systems are not static, and a community may move across the continuum either because of ecologic or evolutionary shifts of the host or pathogen (27 ).
This trade off indicates an evolutionary shift of what traits are most selected for in the current environment in terms of survival.
The Shift Network empowers a growing global movement of people who are creating an evolutionary shift of consciousness that in turn leads to a more enlightened society... one built on principles of sustainability, peace, health and prosperity.
However, we are still not clear about the abortion of the ventral stamens that has been involved in the evolutionary shifts of stamen number during the morphological diversification of zygomorphy in Lamiales s.l.l
In particular, as in Ernande et al. (2004); Dunlop et al. (2007), and Dunlop et al. (2009b), we found that harvesting resulted in evolutionary shifts of PMRN traits that caused earlier maturation at smaller size.
Mr. King takes on the story of Skinner Sweet, the first of the new breed that causes the evolutionary shift, set in the days of the Wild West.
If both native and introduced populations from human-modified habitats can tolerate such conditions, and native populations from natural habitats cannot, this would support the scenario of an evolutionary shift in the native range before long-distance dispersal into the introduced range.
That enhanced differences between sympatric species are the outcome of evolutionary shifts, not simply of the inability of similarly sized species to coexist (for example, because of competitive exclusion or introgression), seems likely owing to the adaptive background of the changes, but must be investigated further by fitness-related studies on traits under divergent selection.
Increasing the probability of harvest causes an evolutionary shift in the migration reaction norms for both age-1 and age-2 individuals: for an individual of the same size, the probability of migration is lowered as the maximal harvest probability increases (Fig. 3A,B).
For this purpose, this paper presents a heuristic optimization algorithm, called the evolutionary shift method, for minimization of the maximum bending moment by virtue of the structural shape or geometry optimization.
