John D. Marshall

What is he best known for?

The fields of study he is best known for:

• Ecology
• Botany
• Ecosystem

John D. Marshall mostly deals with Botany, Isotopes of carbon, Water-use efficiency, Ecology and Stomatal conductance. His Botany research includes elements of Animal science and Horticulture. In his research on the topic of Horticulture, Canopy is strongly related with Biomass.

The concepts of his Isotopes of carbon study are interwoven with issues in δ13C and Photosynthetic pathway. His biological study spans a wide range of topics, including Terrestrial plant, Carbon uptake, Crassulacean acid metabolism and Range. The Ecosystem, Climate change and Intraspecific competition research he does as part of his general Ecology study is frequently linked to other disciplines of science, such as Gene–environment interaction, therefore creating a link between diverse domains of science.

His most cited work include:

• Environmental and physiological determinants of carbon isotope discrimination in terrestrial plants (311 citations)
• Environmental and physiological determinants of carbon isotope discrimination in terrestrial plants (311 citations)
• Sources of Variation in the Stable Isotopic Composition of Plants (291 citations)

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

His main research concerns Botany, Ecology, Photosynthesis, Canopy and Respiration. His Botany research includes themes of δ13C, Horticulture and Isotopes of carbon. His Photosynthesis study incorporates themes from Agronomy and Seasonality.

John D. Marshall works mostly in the field of Canopy, limiting it down to topics relating to Leaf area index and, in certain cases, Canopy conductance and Interception. His research integrates issues of Phloem, Carbon dioxide, Bark and Animal science in his study of Respiration. His study focuses on the intersection of Stomatal conductance and fields such as Water-use efficiency with connections in the field of Dry matter.

He most often published in these fields:

• Botany (43.88%)
• Ecology (26.62%)
• Photosynthesis (19.42%)

What were the highlights of his more recent work (between 2017-2021)?

• Conductance (2.16%)
• Ecosystem (8.63%)
• Scots pine (6.47%)

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

His scientific interests lie mostly in Conductance, Ecosystem, Scots pine, Soil water and Respiration. His Ecosystem research is within the category of Ecology. His study on Scots pine is covered under Botany.

His Botany research focuses on Bark in particular. His work investigates the relationship between Soil water and topics such as Microclimate that intersect with problems in δ13C and Growing season. His studies examine the connections between Respiration and genetics, as well as such issues in Phloem, with regards to Tracheid, Xylem, Shoot, Transpiration stream and Canopy.

Between 2017 and 2021, his most popular works were:

• The handbook for standardized field and laboratory measurements in terrestrial climate change experiments and observational studies (ClimEx) (25 citations)
• Photosynthetic refixation varies along the stem and reduces CO2 efflux in mature boreal Pinus sylvestris trees (13 citations)
• Forest productivity varies with soil moisture more than temperature in a small montane watershed (7 citations)

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

• Ecology
• Botany
• Ecosystem

His primary areas of study are Growing season, Microclimate, Water content, Vapour Pressure Deficit and δ13C. John D. Marshall has included themes like Carbon cycle and Metabolomics in his Growing season study. His study in Microclimate is interdisciplinary in nature, drawing from both Watershed, Soil water and Lapse rate.
