Slide 23 of 25
Notes:
I won’t go into the details of our sensitivity analysis, but will jump to the results. At the local scale, the relative ranking of pools is fairly insensitive to dispersal distance. This means that we don’t need a precise estimate of dispersal distances in order to get reliable results, and it also suggests that we’d be fairly safe applying the marbled salamander model to the rest of our vernal pool amphibians.
The regional metric, on the other hand, is somewhat sensitive to dispersal distance, and quite sensitive to number of dispersing juveniles, which varies over a couple of orders of magnitude. This means that we either need to better estimate of this parameter, or take the regional results with a grain of salt. We’re currently working on representing sensitivity for each pool, in order to find the pools that are important for connectivity across a range of parameter values.
