[tdwg-content] Darwin Core Proposal - environment terms (biome)

Fri May 15 16:56:01 CEST 2015

It would be great to hear from Pier or others more familiar with ENVO on
this.

The ENVO definition of biome is : "A biome is an environmental system to
which resident ecological communities have evolved adaptations." (
http://purl.obolibrary.org/obo/ENVO_00000428)

A resident ecological community from the perspective of a microbe likely
does not care about the large-scale plant and animal communities, so it is
a matter of perspective taken from the point of view of the subject.  To
that end, leaf litter as the biome seems entirely reasonable if the
microbes resident there have evolved adaptations to leaf litter.
