Sensitivity analyses & confidence in parameterization

[Sz-Tim]

The model has a lot of parameters, and some are more robustly informed than others. This is a list of parameters, whether sensitivity analyses are crucial, and what the sources are.

• K Y: Density data from Tom, but primarily for WP
• pr.s Y: From japanese barberry & spicebush
• pr.f N: From our field data, Matt's data
• fec N: From our field data, Matt's data
• age.f Y: Tom's expert knowledge
• pr.sb Y: Mentions in the literature that seeds can survive at least 3 yrs
• pr.est N: Tom's field experiments, our field data
• sdd.max Y: From Merow et al 2011, LaFleur 2009
• sdd.rate Y: From Merow et al 2011, LaFleur 2009
• n.ldd Y: Pulled from thin air, currently implemented differently (seed) than other work
• pr.eat Y: From our field data
• bird.hab Y: From Merow et al 2011, LaFleur 2009
• pr.s.bird N: From various literature sources

Realistically, we may need to narrow down the list or decide on which combinations to vary at once, since we will not be able to do all combinations of all parameters.

[Sz-Tim]

We are using a global sensitivity analysis instead, where all parameters are varied simultaneously. This accounts for possible interactions between parameters.
