Although the relative virulence of a P. ramosa isolate/clone appears to be a good indicator of its competitiveness during multiple infections, the relative dose may alter the competitive outcome.
For example, contest experience may alter future competitive performance.
Differences in the abilities of species to exploit nutrient patches may alter the competitive balance among plant species in plant communities (Bilbrough and Caldwell 1995, Tibbett 2000).
Note, however, that this does not permit exploring the effects of over-exploitation, which could alter competitive dynamics.
Phage can alter competitive interactions between bacterial species in a way that is consistent with the maintenance of coexistence.
It has also been suggested that C. nutans' allelopathic effects may alter the outcome of competitive interactions between grasses and legumes to favour grasses (Wardle et al. 1994).
At the community level, competitive interactions can lead to competitive exclusion, may alter community structure among co-occurring species (Lamb et al. 2009) and can influence plant invasions (Levine 2001; Gurevitch et al. 2011, Bennett et al. 2014).
At present, we are not in a position to make an informed guess about the composition of future phytoplankton communities, nor do we know how competitive interactions may alter the evolutionary response to elevated CO2.
One of the consequences of recommending EvoS for pre-med students, whether they major in a science or not, is that the competitive nature of pre-med students may alter the dynamic of the EvoS program.
This finding may alter the way employers utilize health insurance as a competitive benefit in the market for desired workers.
