A Network Extension of Species Occupancy Models in a Patchy Environment Applied to the Yosemite Toad (Anaxyrus canorus)
Figure 4
Observed and predicted distribution of meadows and watersheds with A. canorus breeding in Yosemite National Park.
The watersheds (Cal 2.2.2 watershed planning units) are colored by the percent of meadows within the basin that are predicted by the Network Boosted GLM model to have breeding. The symbols are centroids for all 2,558 contiguous meadows in the park. Pink and/or red symbols indicate a meadow with observed A. canorus breeding at least once between 1992–2010. Blue symbols were visited at least once with no A. canorus detected. Small black dots are meadows that have not been visited. Solid read symbols are meadows with breeding that are in 90th percentile of impact on park-wide breeding probability if deleted. Note that meadows with high deletion impact are not in the watersheds with highest proportion of ‘good’ meadows.
