Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Botany
  • Gene

James H. Richards mainly investigates Ecology, Transpiration, Stomatal conductance, Botany and Shrub. Ecology is frequently linked to Genetic variation in his study. His Transpiration research integrates issues from Sarcobatus and Soil water, Water potential.

His Hydraulic conductivity study, which is part of a larger body of work in Soil water, is frequently linked to Chrysothamnus, bridging the gap between disciplines. His Stomatal conductance research is multidisciplinary, relying on both Carbon gain, Water metabolism, Agronomy, Carbon metabolism and photoperiodism. His study in Botany is interdisciplinary in nature, drawing from both Arabidopsis thaliana and Arabidopsis.

His most cited work include:

  • Hydraulic lift: consequences of water efflux from the roots of plants. (748 citations)
  • Nighttime Stomatal Conductance and Transpiration in C3 and C4 Plants (382 citations)
  • Genetics of drought adaptation in Arabidopsis thaliana: I. Pleiotropy contributes to genetic correlations among ecological traits (314 citations)

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

James H. Richards mainly focuses on Agronomy, Botany, Ecology, Transpiration and Soil water. His Agronomy study combines topics from a wide range of disciplines, such as Salinity and Nutrient. His research integrates issues of Quantitative trait locus, Genetic variation and Horticulture in his study of Botany.

His research in Transpiration intersects with topics in Nocturnal, Hydraulic conductivity, photoperiodism and Stomatal conductance. His Soil water research incorporates themes from Desert climate, Litter and Water content. His studies in Water potential integrate themes in fields like Canopy and Hydraulic redistribution.

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

James H. Richards mostly deals with Botany, Genetics, Genetic variation, Ecology and Agronomy. His Botany study deals with Horticulture intersecting with Plant species, Co2 concentration and Morning. His Gene, Allele and Quantitative trait locus study in the realm of Genetics connects with subjects such as Expression quantitative trait loci.

The study incorporates disciplines such as Adaptation, Arabidopsis thaliana and Phenology in addition to Genetic variation. Ecology and Field conditions are frequently intertwined in his study. As part of his studies on Stomatal conductance, James H. Richards often connects relevant subjects like Transpiration.

Between 2010 and 2019, his most popular works were:

  • Characterizing genomic variation of Arabidopsis thaliana: the roles of geography and climate. (153 citations)
  • Physiological Genomics of Response to Soil Drying in Diverse Arabidopsis Accessions (116 citations)
  • Pleiotropy of FRIGIDA enhances the potential for multivariate adaptation (94 citations)

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

  • Botany
  • Ecology
  • Gene

Genetic variation, Arabidopsis thaliana, Adaptation, Genetics and Water-use efficiency are his primary areas of study. James H. Richards has included themes like Phenology, Species distribution, Growing season and Geographical distance in his Adaptation study. The various areas that James H. Richards examines in his Water-use efficiency study include Transpiration, Genetic correlation and Stomatal conductance.

His Stomatal conductance research is within the category of Botany. His Agronomy research is multidisciplinary, incorporating perspectives in Flowering time, Indirect selection, Specific leaf area and Water content. His Local adaptation research entails a greater understanding of Ecology.
