Relief begets diversity. Mountain land-
scapes host a rich variety of fl ora and
fauna, engendered by their concen-
trated diversity of climatic and ecolog-
ical conditions. Two centuries on from
Alexander von Humboldt’s pioneering
research in the Tropical Andes, moun-
tains remain fertile ground for study-
ing the interplay between the biological and
physical environment and for understanding
the evolutionary adaptations that permit sur-
vival of animals, plants, and people at higher
elevations. Mountains under the sea, too, are
magnets for a diversity of life, much of which
has yet to be explored and described.
Mountain environments are also fragile, as
they are in the fi ring line of human exploita-
tion and climate change. As temperatures rise,
vegetation zones shift upslope, squeezing the
ranges of montane organisms. As glaciers re-
cede and forests dwindle, the capacity of the
montane environment to supply water to sur-
rounding lowlands decreases. The protection
of the world’s uplands, for their natural riches
and the human communities that rely on them,
is becoming increasingly urgent.
