Spatial characteristics of habitat patches and population survival

The effect of the spatial arrangement of habitat patches on the survival of resident populations were considered in a stochastic model using population parameters appropriate to Peromyscus leucopus. The 34 possible arrangements of connections among five otherwise identical patches were simulated in order to determine the survival probabilities and population sizes.The main findings are that populations in completely isolated patches have lower survival probabilities than those in patches that are connected to other patches, are connected to the survival probabilities of populations in connected patches increases with the size of the largest geometric figure of which the patch is a part. The results are discussed in the context of resource management.
