Younger Dryas: Effects on Biota

Transport is a large factor on how or if a species can survive colder temperatures. Ocean currents may spread species over different areas and only those areas that are favored will allow for the continued growth and habitat of the species. Winds can also transport some things like spores or seeds, which may be dispersed to areas favorable to the species or not. If blown past their germination limit it may be distructive and may lead to death of the species, or it may extend growth range of the species if taken into more temperate regions like away from the advancing glacier.
