ImportanceExternal ecological connectivity can enhance resilience by facilitating recovery and renewal in systems, for example the dispersal of seeds or the spread of pollinators between similar habitats in different SES. Over-connectivity can, however, mean that disturbance events cascade rapidly through a system causing system collapse, for example impacts on marine ecosystems from run-off of land-based pollution. Some degree of modularity to "contain disturbances by compartmentalizing social-ecological systems" is beneficial for resilience (Carpenter et al. 2012)
Definition

External ecological connectivity is the manner and extent to which populatiions and species (e.g., eggs, larvae, juveniles, adults) or impacts (e.g., pollution spread by water flow) disperse, migrate or interact across ecological systems (e.g., land-sea, highlands-lowlands, transboundary ecosystem).
