We are thrilled to announce the release of the new interim PCoD code (v3.0) on the Marine Scotland website.
We have been working with John Harwood to develop and test the new code and are excited with the new code developments:
- The code now runs much faster than before which is great as it allows users to run more development scenarios/parameter combinations.
- The way in which residual days of disturbance is modelled has changed and the code can now model different amounts of residual disturbance depending on how close the animal was from the noise source when it was impacted
- The piling scenarios schedule is now simpler and easier to use
- The model can now include density dependence
- The way in which demographic stochasticity is modelled has been improved
- We have changed how the effects of “moderate” disturbance on survival or birth rate is calculated
The code comes with a shiny new helpfile that takes the user through the code step by step from installing and setting up R and R studio, to creating piling schedules, setting the user defined input parameters and interpreting the outputs. There is also an updated version of the Harwood and King paper which describes the sensitivity of UK marine mammal populations to renewable developments and provides updated recommended demographic parameters for different species.
