Finally, we determined (vi) extinction frequencies of the different types of protocols.
Bohrer et al. (2005) suggest that selection should favour long-distance dispersal under intermediate local extinction frequencies.
This process continues until either the growth rates of the two cell types are equal and their relative frequencies are stable or one cell type is driven towards extinction (zero frequency).
Invasion of S. aureus into a toxin-producing S. epidermidis resident was positively frequency-dependent with highest initial frequencies invading the fastest and lower initial frequencies going to extinction (Fig. 5A,C) (frequency × inhibition, F1,64 = 46.5, P < 0.001).
We use the model to investigate how equilibrium patch occupancy is influenced by four critical parameters: colonization rate, extinction rate, disturbance frequency and the rate of habitat succession.
Thus, we examined whether extinction alters the frequency of bursting in the mPFC.
The local extinction and colonization frequencies modelled by generalised linear mixed models, were significantly, although poorly, correlated to the respective observed frequencies of extinction (r2 = 0.50, P<0.0001) and colonization (r2 = 0.29, P<0.0001) prior to accounting for random effects.
Indeed, the re-sampling procedure that we performed in order to account for random processes showed that none of the explanatory variables had significantly positive absolute weights of evidence to explain either the local extinction or colonisation frequencies (Figs 5c and 5d).
We analyzed among-strain variation in extinction, successful transfer frequencies, developmental delay, and mortality for the nematodes evolved at N = 1.
In the case of strain rate forcing, the flame is found to undergo oscillatory extinction if the forcing frequency is less than the pulsation frequency.
