Dianthus
An sf object with point data for 65 populations and 31 variables, in the following slots:
CRS("+init=epsg:31468")
Boundary box: spatial extent
Patch-level variables:
Patch ID
Sample size
Population size (2009) in five categories: "0": absent; "1": 1 - 3; "2": 4 - 39; "3": 40 - 99; "4": 100 or more. In most cases, all individuals were sampled for categories "1" and "2".
Grazing system: "East", "South", "West", NA (ungrazed)
Grazing intensity: "Continuous": grazed 3 - 5 times throughout growing season; "Intermittent": grazed only some years or only late in season; "Ungrazed"
Patch size in ha
Number of dynamic structural element types present in 2008 (rock debris, animal burrows, ant hills, erosion)
Species presence/absence in 1989
Species presence/absence in 2009
Shannon diversity index
Observed heterozygosity
Expected heterozygosity
Rarefied allelic richness
Inbreeding coefficient
Connectivity index Si, calculated based on Euclidean distances and using binary source patch weights (species presence/absence)
Connectivity index Si, calculated based on Euclidean distances and using patch weights proportional to patch size (if species present)
Connectivity index Si, calculated based on Euclidean distances and using patch weights proportional to the rank of PopSize (ranging from 0 - 4)
Connectivity index Si, calculated based on the number of continuously grazed patches between source and focal patch, using binary source patch weights (species presence/absence)

Connectivity index Si, calculated based on the number of continuously grazed patches between source and focal patch, using patch weights proportional to the rank of PopSize (ranging from 0 - 4)
Connectivity index Si, calculated based on the number of continuously or intermittently grazed patches between source and focal patch, using binary source patch weights (species presence/absence)
Connectivity index Si, calculated based on the number of continuously or intermittently grazed patches between source and focal patch, using patch weights proportional to patch size (if species present)
Connectivity index Si, calculated based on the number of continuously or intermittently grazed patches between source and focal patch, using patch weights proportional to the rank of PopSize (ranging from 0 - 4)
Connectivity index Si, calculated based on whether or not source and focal patch are in the same grazing system, using binary source patch weights (species presence/absence)
Connectivity index Si, calculated based on whether or not source and focal patch are in the same grazing system, using patch weights proportional to patch size (if species present)
Connectivity index Si, calculated based on whether or not source and focal patch are in the same grazing system, using patch weights proportional to the rank of PopSize (ranging from 0 - 4)
