ARRIVAL
AND ESTABLISHMENT
When the tips of the Galapagos volcanoes first appeared
above the sea surface, some three to five million
years ago, they were isolated from life. We will never
know how colonization occurred, what we do know is
that one thousand kilometers separate the Galapagos
from the mainland and despite this barrier, a number
of species have made it to the islands. Of course,
species are present due to their capacity to disperse,
whether actively or passively, but also their ability
to establish themselves after arrival. |
