植物也遷徙 plants travel with birds

blog_illl160-12

多年來科學家不明白生在南美洲的苔蘚是如何直接傳播至遙遠的南極去,原來它們是坐了順風鳥!小型植物的種子會粘在鳥的羽毛上,然後季候鳥會帶著這些種子一起遷徙,把牠們傳播到半個地球外的地方!

it was unsure how plants could travel to arctic from the south america but nowhere else in between, now that the scientists explain they got a lift on migrating birds! little plant seeds are found trapped in the feathers of the birds, and they migrated with these birds to the other side of the earth!
