Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Botany
  • Ecosystem

Richard B. Thomas spends much of his time researching Photosynthesis, Botany, Carbon dioxide, Stomatal conductance and Agronomy. His studies deal with areas such as Ecology, Acclimatization and Carbon cycle as well as Photosynthesis. The Botany study combines topics in areas such as Biomass and Horticulture.

His Carbon dioxide research incorporates themes from Nutrient and Malvaceae. In his study, Photosynthetic acclimation, Biomass, Shoot and Starch is inextricably linked to Photosynthetic capacity, which falls within the broad field of Stomatal conductance. His Agronomy research includes themes of Primary production and Carbon dioxide in Earth's atmosphere.

His most cited work include:

  • Modelling photosynthesis of cotton grown in elevated CO2 (671 citations)
  • Root Restriction as a Factor in Photosynthetic Acclimation of Cotton Seedlings Grown in Elevated Carbon Dioxide (404 citations)
  • Net primary production of a forest ecosystem with experimental CO2 enrichment (403 citations)

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

Richard B. Thomas mostly deals with Botany, Photosynthesis, Carbon dioxide, Horticulture and Agronomy. His Botany research is multidisciplinary, incorporating perspectives in Nutrient and Animal science. The concepts of his Photosynthesis study are interwoven with issues in Acclimatization and Understory.

His Carbon dioxide research is multidisciplinary, incorporating elements of Dry weight, Phytotron, Malvaceae and Respiration. His Horticulture study combines topics from a wide range of disciplines, such as Neodiprion lecontei, Starch, Growing season and Sawfly. His studies in Agronomy integrate themes in fields like Nitrogen fixation, Reproduction, Rhizobium and Plant litter.

He most often published in these fields:

  • Botany (54.93%)
  • Photosynthesis (40.85%)
  • Carbon dioxide (38.03%)

What were the highlights of his more recent work (between 2006-2021)?

  • Ecology (15.49%)
  • Ecosystem (14.08%)
  • Photosynthesis (40.85%)

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

His primary areas of investigation include Ecology, Ecosystem, Photosynthesis, Stomatal conductance and Dendrochronology. His work on Forest ecology, Climate change, Climate model and Global warming as part of his general Ecology study is frequently connected to Toxicodendron radicans, thereby bridging the divide between different branches of science. His study on Primary production is often connected to Landscape ecology as part of broader study in Ecosystem.

The subject of his Photosynthesis research is within the realm of Botany. His research investigates the connection between Botany and topics such as Horticulture that intersect with issues in Growing season. His biological study spans a wide range of topics, including Acclimatization, Carbon dioxide, Tree species and Animal science.

Between 2006 and 2021, his most popular works were:

  • Forest carbon use efficiency: is respiration a constant fraction of gross primary production? (319 citations)
  • Elevated CO2 affects photosynthetic responses in canopy pine and subcanopy deciduous trees over 10 years: a synthesis from Duke FACE (119 citations)
  • Elevated temperatures increase leaf senescence and root secondary metabolite concentrations in the understory herb Panax quinquefolius (Araliaceae). (96 citations)

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

  • Ecology
  • Botany
  • Ecosystem

His primary scientific interests are in Ecosystem, Forest ecology, Understory, Deciduous and Photosynthesis. Richard B. Thomas has included themes like Experimental forest, Felling, Ecological succession, Clearcutting and Carbon sequestration in his Ecosystem study. His work deals with themes such as Agroforestry, Primary production and Temperate deciduous forest, which intersect with Forest ecology.

His Understory research integrates issues from Growing season, Horticulture and Stomatal conductance. His study in Deciduous is interdisciplinary in nature, drawing from both Liquidambar styraciflua, Canopy and Crown. The various areas that Richard B. Thomas examines in his Biomass study include Carbon cycle and Taiga.
