We may add a third axis representing salinity, thus defining a three- dimensional
space (Figure lb) containing a region representing tolerable combinations of
temperature, prey size and salinity. To take into account other environmental
factors, ...

What factors limit the geographic range of a species? Over a geographic transect
the environment usually changes gradually, but the edge 'of a species' range is
often abrupt. Why? Why should it be incapable of adapting enough to extend just
