Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Photosynthesis

His primary areas of study are Botany, Photosynthesis, Carbon dioxide, Transpiration and Stomatal conductance. His Botany research integrates issues from Humidity and Analytical chemistry. The Photosynthesis study combines topics in areas such as Electron transport chain, Partial pressure and Carboxylation.

His research integrates issues of Photorespiration, Starch, Isotopes of carbon, Photosynthetic capacity and Vascular bundle in his study of Carbon dioxide. His Transpiration research includes elements of Agronomy, Canopy, Turgor pressure, Water-use efficiency and Biomass. His Stomatal conductance study also includes

  • Horticulture and related Irrigation,
  • Ecology which is related to area like Plant growth.

His most cited work include:

  • A biochemical model of photosynthetic CO 2 assimilation in leaves of C 3 species (5976 citations)
  • Carbon Isotope Discrimination and Photosynthesis (5077 citations)
  • Some relationships between the biochemistry of photosynthesis and the gas exchange of leaves. (3940 citations)

What are the main themes of his work throughout his whole career to date?

Botany, Photosynthesis, Transpiration, Agronomy and Stomatal conductance are his primary areas of study. The study incorporates disciplines such as Carbon dioxide, Horticulture and Isotopes of carbon in addition to Botany. Graham D. Farquhar has researched Photosynthesis in several fields, including Atmospheric sciences and Respiration.

His Atmospheric sciences research incorporates elements of Ecology, Canopy and Pan evaporation. His Transpiration research is multidisciplinary, incorporating perspectives in Water use, Humidity, Leaf water, Xylem and Isotopes of oxygen. His work on Poaceae as part of general Agronomy research is often related to Genetic variation, thus linking different fields of science.

He most often published in these fields:

  • Botany (43.50%)
  • Photosynthesis (29.75%)
  • Transpiration (20.50%)

What were the highlights of his more recent work (between 2011-2021)?

  • Photosynthesis (29.75%)
  • Botany (43.50%)
  • Atmospheric sciences (13.00%)

In recent papers he was focusing on the following fields of study:

His scientific interests lie mostly in Photosynthesis, Botany, Atmospheric sciences, Transpiration and Stomatal conductance. Graham D. Farquhar combines subjects such as Respiration and Isotopes of carbon with his study of Photosynthesis. His biological study spans a wide range of topics, including Isotopes of oxygen and Agronomy.

His study in Atmospheric sciences is interdisciplinary in nature, drawing from both Evaporation, Pan evaporation, Precipitation, Carbon sink and Global change. In general Transpiration study, his work on Transpiration stream often relates to the realm of Genetic variation, thereby connecting several areas of interest. His work deals with themes such as Ecology, Canopy, Carbon dioxide and Relative humidity, which intersect with Stomatal conductance.

Between 2011 and 2021, his most popular works were:

  • Environmental and physiological determinants of carbon isotope discrimination in terrestrial plants (311 citations)
  • Impact of CO2 fertilization on maximum foliage cover across the globe's warm, arid environments (297 citations)
  • Sensitivity of plants to changing atmospheric CO2 concentration: From the geological past to the next century (234 citations)

In his most recent research, the most cited papers focused on:

  • Botany
  • Ecology
  • Photosynthesis

The scientist’s investigation covers issues in Photosynthesis, Botany, Stomatal conductance, Precipitation and Climate change. His Photosynthesis study combines topics in areas such as Crop growth, Agricultural engineering and Crop yield. His Botany research is multidisciplinary, relying on both Carbon dioxide and Isotopes of oxygen.

The concepts of his Stomatal conductance study are interwoven with issues in Ecology, Agronomy, Water-use efficiency and Horticulture. His work carried out in the field of Precipitation brings together such families of science as Arid, Eucalyptus, Atmospheric sciences and Allometry. Graham D. Farquhar interconnects Isotopologue and Isotopes of carbon in the investigation of issues within Transpiration.
