    The Alveolar–arterial gradient (A-aO 2, or A–a gradient), is a measure of the difference between the alveolar concentration (A) of oxygen and the arterial (a) concentration of is used in diagnosing the source of hypoxemia.. The A–a gradient helps to assess the integrity of the alveolar capillary unit. For example, in high altitude, the arterial oxygen PaO.

Notes are numbered sequentially and grouped at the end, with the page(s) they originally appeared at the bottom of given within double brackets. Elevational diversity gradient (EDG) is an ecological pattern where trends in biodiversity occur at different EDG states that species richness tends to increase as elevation increases, up to a certain point, creating a "diversity bulge" at middle elevations.

There have been multiple hypotheses proposed for explaining the EDG, none of which accurately describe the phenomenon in full. Jackson, Stephen T., Postglacial vegetation changes along elevational gradient in the Adirondack Mountains (New York): A study of plant macrofossils.
