Separating the effects of climate, bycatch, predation and harvesting on tītī (Ardenna grisea) population dynamics in New Zealand: A model-based assessment
Fig 2
Fit of the demographic models to harvest data.
Observed and predicted catch per unit effort (CPUE) data from harvesting of tītī chicks in New Zealand during the period 1979–1998. In both plots the solid line shows the model-averaged posterior mean for CPUE. In (a) the dashed lines show the 95% model-averaged credible interval; in (b) the dots are the observed CPUE values and the dashed lines show the 95% model-averaged 95% prediction interval. Model averaging was performed using WAIC model weights.
