Ecology

Ecology is a science that examines the relationships organisms have with one another and with their environment. Greenhouse gas concentrations, such as those of carbon dioxide (CO₂), methane (CH₄), and water (H₂O), can directly and indirectly influence an ecosystem’s behavior and health. Gas concentrations, as well as isotopic signatures (e.g. δ¹³C), can act as indicators of ecosystem attributes such as transpiration levels or migratory patterns. Monitoring methods include ground sampling, ambient air measurements, and airborne surveys.
