Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Photosynthesis

Photosynthesis, Botany, Canopy, Agronomy and Leaf area index are his primary areas of study. Tadaki Hirose studies Photosynthetic capacity, a branch of Photosynthesis. In his research, Productivity, Fagaceae, Evergreen, Photosynthetic acclimation and Betula ermanii is intimately related to Deciduous, which falls under the overarching field of Photosynthetic capacity.

His research in the fields of Interspecific competition, Fagus crenata and RuBisCO overlaps with other disciplines such as Carboxylation. Canopy is a primary field of his research addressed under Ecology. The various areas that he examines in his Agronomy study include Plant community and Assimilation.

His most cited work include:

  • Photosynthesis or persistence: nitrogen allocation in leaves of evergreen and deciduous Quercus species (302 citations)
  • Leaf anatomy as a constraint for photosynthetic acclimation: differential responses in leaf anatomy to increasing growth irradiance among three deciduous trees (210 citations)
  • Allocation of nitrogen to cell walls decreases photosynthetic nitrogen‐use efficiency (201 citations)

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

Tadaki Hirose focuses on Photosynthesis, Botany, Agronomy, Canopy and Xanthium. Tadaki Hirose is interested in Photosynthetic capacity, which is a branch of Photosynthesis. His Botany study frequently links to other fields, such as Horticulture.

The concepts of his Agronomy study are interwoven with issues in Plant ecology and Plant physiology. He has included themes like Herbaceous plant and Leaf area index in his Canopy study. Tadaki Hirose works mostly in the field of Xanthium, limiting it down to topics relating to Competition and, in certain cases, Intraspecific competition.

He most often published in these fields:

  • Photosynthesis (62.96%)

  • Productivity (13.58%)
  • Dry weight (19.75%)

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

His primary areas of study are Agronomy, Productivity, Dry weight, Botany and Photosynthesis. His Agronomy research includes elements of Acclimatization, Evergreen and Plant physiology. His study looks at the relationship between Dry weight and fields such as Xanthium, as well as how they intersect with chemical problems.

Botany is closely attributed to Horticulture in his study. His Horticulture research is multidisciplinary, incorporating perspectives in Carbon dioxide and Allometry. His research ties Respiration and Photosynthesis together.

Between 2010 and 2020, his most popular works were:

  • Nitrogen use efficiency revisited (34 citations)
  • Optimal use of leaf nitrogen explains seasonal changes in leaf nitrogen content of an understorey evergreen shrub. (26 citations)
  • Effects of elevated CO2 concentration on seed production in C3 annual plants (25 citations)

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

  • Botany
  • Ecology
  • Photosynthesis

Tadaki Hirose focuses on Agronomy, Botany, Evergreen, Acclimatization and Photosynthesis. His research integrates issues of Endosperm and Interspecific competition in his study of Agronomy. His research on Botany frequently connects to adjacent areas such as Animal science.

His Evergreen study combines topics from a wide range of disciplines, such as Shrub, Aucuba japonica and Photosynthetic capacity.
