Abstract: Motivated by recent findings of enhanced species survival when fragmented habitats are reconnected through narrow strips of land (Pimm and Jenkins, 2019), we study the effect of a corridor connecting two regions on the lifetime of three models exhibiting extinction/survival phase transitions: the basic contact process (CP), the diffusive contact process, and the two-species contact process (2SCP) using Monte Carlo simulations. For the basic contact process we also present semianalytic solutions on complete graphs. We find that connecting two regions increases the lifetime when the reproduction rate is greater than its critical value. The lifetime enhancement increases with the reproduction rate; for square regions, wide and short corridors provide the best enhancement.
