Stability of policing is crucial for long term coexistence of multiple strategies, with faithful monogamy comprising substantial part of the population.
In conjunction with expression data, we demonstrated that both TFIIAγ genes following the duplication were functional and under strong selection constraint in Oryzeae and its relatives, providing no evidence that either gene evolved new functions or became a pseudogene despite their long-term coexistence for at least 50 MYA.
A simple theoretical framework reveals that for a broad set of cases, while inter-group competition generates incentives for violence, the presence of non-replicable, non-expropriable inter-group complementarities becomes necessary to sustain peaceful coexistence over long time horizons.
Yet many grizzly experts agree that teaching the bears to associate human settlements with unrelenting hard times is probably the best approach for long-term coexistence.
Even while we may not have created conditions necessary for long-term coexistence, our results point to a simple, yet important, conclusion that heterogeneity in-and-of-itself does not alter the effects of species richness on community biomass.
Several studies proposed that multiple factors need to act jointly for long-term coexistence of multiple resisto- and infectotypes [ 33].
As a preliminary step, an extensive exploration of the parameter space was carried out in order to determine which parameter combinations allow for long-term coexistence of pathogens and hosts.
This extension is critical given that antigenic mutations acquire their selective advantage through immune escape, which reduces competition for susceptible hosts and therefore in principle could allow for long-term coexistence of virus strains through niche partitioning of the host population (Cobey, 2014).
Regime supporters alarmingly brandish the spectre of fundamentalist Islamist rule as a hellish scenario for minorities, but this would be a first in Syria, blessed with peaceful coexistence long before the Assad regime's claim to fame on secularism.
For long-term stability, the government should encourage an informed and rational debate and preach peaceful coexistence among ethnic groups and religions.
