The salt marsh harvest mouse has an average maximum age of 12 months, however most of the mice only live to about eight months. They do not have a high reproductive cycle as other species of mice would. They usually have around 4 offspring per litter and usually only once a year. They are a density- dependent species meaning when populations begin to rise the breeding time is pushed back into later spring. However if population density is too high, the populations can face the reality of extinction. Summer, when salinity of water and vegetation increases the mice have a notable advantage due to their ability to drink and survive purely on salt water. The northern species can survive purely on salt water, however prefers fresh to salt. Souther species can survive on either and does not display a preference to either.

Famous quotes containing the word lifestyle:
“The hippie is the scion of surplus value. The dropout can only claim sanctity in a society which offers something to be dropped out of—career, ambition, conspicuous consumption. The effects of hippie sanctimony can only be felt in the context of others who plunder his lifestyle for what they find good or profitable, a process known as rip-off by the hippie, who will not see how savagely he has pillaged intricate and demanding civilizations for his own parodic lifestyle.”
—Germaine Greer (b. 1939)
