Paul Gordon Jarvis (23 May 1935 – 5 February 2013) FRS FRSE[1][3] was a leading ecologist and Professor of Forestry and Natural Resources at the University of Edinburgh from 1975 to 2001.

[9] He went to graduate school at the University of Sheffield where he was awarded a PhD in 1960 for research on the growth and regeneration of Irish oak Quercus petraea.

[1][9] His certificate of election reads: Professor Jarvis has made a unique contribution to plant ecology by elucidating the dependence of transpiration and photosynthesis on physiological and environmental factors over a wide range of scales from cellular to regional.

He was a pioneer in measuring photosynthesis and respiration in a forest stand and in estimating CO₂ fluxes as a function of light transmission and interception.

[18] He served on the editorial board of Photosynthetica, was the President of the Society for Experimental Biology from 1993 to 1995[9] and a Commissioner of the Countryside Commission for Scotland.
