| How
Do the Rocky Mountains Affect Migration?
"Most
scientists would agree that the Rocky Mountains provide a barrier
that prevents complete intermixing of the two populations,"
says Dr. Karen Oberhauser. Cold
temperatures in the mountain region, not the height of the mountains
themselves, are probably an important factor that affects when and
where monarchs can travel. In addition to temperatures or wind direction,
what other factors could explain why monarchs migrate where they
do?
