Statement I is true because dispersal is a mechanism by which plants and animals ensure the survival and persistence of their populations. Statement II is not entirely accurate because while climate is a factor, other factors such as dispersal ability also play a role in colonizing devastated areas. Statement III is true because dispersed seeds can grow into new plants and help expand a plant population's range. Statement IV is false because dispersal can occur over short and long periods, and it is not limited to evolutionary time scales.
