Invader success increases with disturbance
To understand the diversity loss at higher pulse frequencies in the invaded treatments, we quantified invader success (proportion and density of invader in the final community) and tested whether this differed with pulse frequency. Invader proportion significantly increased with increasing pulse frequency (effect size: 47.87, p<0.001; Fig. 3A) and with pulse frequncy2(effect size: -58.78, p<0.001), as did invader density (effect size of pulse: 37.79, p<0.001; effect size of pulse frequncy2: -53.51, p<0.001; Fig. 3B). Overall, these results show invader success is greater at higher pulse frequencies than low.
