cabrera: Modified patch occupancy data of Cabrera vole
Description
One season patch occupancy dataset for Microtus cabrerae in SW
Portugal. This dataset is in the format produced by species.graph,
convert.graph or import.shape (class 'metapopulation'), and it was created by converting a
data frame using the function convert.graph. The data frame had the
information of one snapshot of patch occupancy data of Cabrera vole
(Microtus cabrera) in southwestern Portugal.format
A list with the following elements:
- mapsize - 8200 (landscape mosaic side length, in meters).
- minimum.distance - 10.04 (minimum distance between patches centroids).
- mean.area - 0.46 (mean area, in hectares).
- SD.area - 1.05 (SD of the area).
- number.patches - 793 (number of patches).
- dispersal - 800 (mean dispersal ability of the species).
- distance.to.neighbours - data frame with pairwise distance between patches.
- nodes.characteristics - data frame with the characteristics of each patch.

Original field data was obtained during project PERSIST (PTDC/BIA-BEC/105110/2008).Details
To create this sample dataset the occupancy status of patches was
scrambled, however the proportion of occupied patches was kept.
