This Concept Map, created with IHMC CmapTools, has information related to: Monarch Butterfly (2ndary article), Monarch Butterflies migrate by navigating and orienting, "slight decrease in temperature" = "slight cooling" (in the Mountains) triggering the responses of individuals: to migrate "North" now!, cooling temperatures & decreasing daylenght to avoid dying = "evolutionary consequence" of migrating South in Fall, Monarch Butterflies migrating North (Spring) from Mexico (mountains) (overwintering site), migration direction (now North) using cues from the "slight decrease in temperature" = "slight cooling" (in the Mountains), from Mexico (mountains) (overwintering site) in which the over-wintering populations, an internal compass in the monarch butterflies' antennae, navigating and orienting by using cues from the sun, from eastern US and southern Canada using cues from the cooling temperatures & decreasing daylenght, molecules in their body: causing changes in protein synthesis leading to changes in "ion channel function" (which can affect physiology), navigating and orienting by using cues from their Magenetic Sense, navigating and orienting by using cues from polarized light, "slight decrease in temperature" = "slight cooling" (in the Mountains) triggering the responses of molecules in their body: causing changes in protein synthesis, to Mexico (mountains) (overwintering site) using cues from the cooling temperatures & decreasing daylenght, the sun with an internal compass, from Mexico (mountains) (overwintering site) in which the to eastern US and southern Canada, Monarch Butterflies migrating South (Fall) from eastern US and southern Canada, Monarch Butterflies migrating North (Spring) to eastern US and southern Canada, Monarch Butterflies migrating South (Fall) to Mexico (mountains) (overwintering site), over-wintering populations change migration direction (now North)
