cijk = joining between patch j and k (0 = unjoined, 1 = joined) of the same patch type, based on a user-specified threshold distance. ni = number of patches in the landscape of each patch type (i). |
| Description | CONNECT equals the number of functional joinings between all patches of the same patch type (sum of cijk where cijk = 0 if patch j and k are not within the specified distance of each other and cijk = 1 if patch j and k are within the specified distance), divided by the total number of possible joinings between all patches of the same type, multiplied by 100 to convert to a percentage. |
| Units | Percent |
| Range | 0 ≦ CONNECT ≦ 100 CONNECT = 0 when either the landscape consists of a single patch, or all classes consist of a single patch, or none of the patches in the landscape are "connected" (i.e., within the user-specified threshold distance of another patch of the same type). CONNECT = 100 when every patch in the landscape is "connected." |
| Comments | Connectance is defined on the number of functional joinings between patches of the same type, where each pair of patches is either connected or not based on a user-specified distance criterion. Connectance is reported as a percentage of the maximum possible connectance given the number of patches. Note, connectance can be based on either Euclidean distance or functional distance. |
