Using the ‘known fates’ model structure in RMark, and the black duck telemetry data set, create these additional models to explain survival
condition index and bird age have an additive effect on survival
there is an interaction between condition index and bird age in their effect on survival
there is an interaction between minimum temperatures and weight on their effect on survival
Perform model averaging of real parameter values
Using the ‘nest survival’ model structure in RMark (Chapter 17 and Appendix C.18, MARK book), and the mallard nest survival set, build some additional models predicting duck nest survival. Run the code and interpret the results:
Which one is the best model?
How is nest survival affected by nest age?
How is nest survival affected by surrounding vegetation?
Does nest survival vary with the habitat type where the nest was located?
Create model average predictions of nest survival in relation to Robel vegetation index and use R to create plots of predictions with unconditional confidence intervals
