|Ecosystem ecology is a subdiscipline within ecology that deals with energy flow and nutrient and
material cycling through landscapes or elements thereof. Ecosystem ecology represents a unique
approach to asking ecological questions as much as (or more than) particular types of ecological
questions per se, and as such, is a discipline to which not many students get exposed. It is,
however, an area of active research nationally and internationally, and perspectives gained from
the "ecosystem approach" have proven very valuable to conservation biologists, natural resource
management agencies, and governments at all levels.
