The choice of resource regimes is a choice over the cost of transacting and the ability and willingness to cooperate.
Hence, it is argued that an important role of resource regimes is their capacity to define whether the issue is one of individual gain or cooperation.
In addition, the results suggest that lessons learned from common pool resources can be extended to the analysis of resource regimes other than common property, and emphasize the potential applicability of the framework used for assessing lessons about institutional durability from ongoing PWES.
Limited availability of resources should also promote trade-offs between fitness-related traits that compete for the same resource pool (e.g. somatic maintenance vs. reproductive investment), and thus the optimal within-individual allocation of resources is likely to change across resource regimes [1] [3].
Combinations of sugars were presented either simultaneously or as temporally fluctuating resource regimes.
After 2000 generations, the mean fitness of all populations had increased significantly under all seven resource regimes (Table 1).
(3) Among-population genetic variation for fitness was highest, and most sustained over time, in those groups that had evolved under fluctuating resource regimes.
Each population had the opportunity to adapt to one of seven different resource regimes, but other aspects of their environment (e.g., temperature and base minimal medium) were common to all of the selection regimes.
Although the specific adaptations that occurred in the populations are not yet known, we can imagine a scenario where one might well expect greater among-population divergence under the fluctuating resource regimes.
In this study, we monitored the evolution of 42 experimental populations of E. coli under 7 resource regimes for 2000 generations in order to investigate the effects of environmental complexity on their dynamics.
