What is he best known for?
The fields of study he is best known for:
His primary scientific interests are in Soil respiration, Temperate deciduous forest, Ecology, Primary production and Agronomy.
His biological study spans a wide range of topics, including Temperate climate and Deciduous.
The study incorporates disciplines such as Atmospheric sciences and Phenology in addition to Temperate deciduous forest.
Hiroshi Koizumi focuses mostly in the field of Primary production, narrowing it down to matters related to Biomass and, in some cases, Grassland, Biometeorology, Diameter at breast height and Main stem.
Within one scientific family, he focuses on topics pertaining to Q10 under Agronomy, and may sometimes address concerns connected to Soil test and Arctic.
His work deals with themes such as Seasonality and Growing season, which intersect with Respiration.
His most cited work include:
- Seasonal changes in the contribution of root respiration to total soil respiration in a cool-temperate deciduous forest (213 citations)
- Seasonal and annual variations in soil respiration in a cool-temperate deciduous broad-leaved forest in Japan (139 citations)
- Differences in soil respiration between different tropical ecosystems (127 citations)
What are the main themes of his work throughout his whole career to date?
Hiroshi Koizumi spends much of his time researching Soil respiration, Agronomy, Ecology, Botany and Atmospheric sciences.
Hiroshi Koizumi has researched Soil respiration in several fields, including Temperate deciduous forest and Carbon dioxide.
His Temperate deciduous forest research incorporates elements of Phenology and Seasonality.
His Agronomy study integrates concerns from other disciplines, such as Soil water, Soil fertility, Carbon cycle and Water content.
As a part of the same scientific study, Hiroshi Koizumi usually deals with the Botany, concentrating on Horticulture and frequently concerns with Japonica.
His Atmospheric sciences research integrates issues from Snow, Eddy covariance, Ecosystem respiration and Hydrology.
He most often published in these fields:
- Soil respiration (32.85%)
- Agronomy (30.66%)
- Ecology (29.93%)
What were the highlights of his more recent work (between 2013-2021)?
- Agronomy (30.66%)
- Ecosystem (20.44%)
- Ecology (29.93%)
In recent papers he was focusing on the following fields of study:
Hiroshi Koizumi mainly focuses on Agronomy, Ecosystem, Ecology, Soil water and Primary production.
Hiroshi Koizumi combines subjects such as Soil carbon and Nutrient with his study of Agronomy.
His work in the fields of Carbon cycle overlaps with other areas such as Production.
All of his Soil water and Soil respiration and Soil organic matter investigations are sub-components of the entire Soil water study.
The Soil respiration study combines topics in areas such as Atmospheric sciences, Deciduous and Mangrove.
His studies deal with areas such as Biomass, Forest ecology and Forest floor as well as Primary production.
Between 2013 and 2021, his most popular works were:
- Utilization of ground-based digital photography for the evaluation of seasonal changes in the aboveground green biomass and foliage phenology in a grassland ecosystem (31 citations)
- Deposition and decomposition of cattle dung and its impact on soil properties and plant growth in a cool-temperate pasture (24 citations)
- Detection of the different characteristics of year-to-year variation in foliage phenology among deciduous broad-leaved tree species by using daily continuous canopy surface images (23 citations)
In his most recent research, the most cited papers focused on:
Hiroshi Koizumi mostly deals with Agronomy, Nutrient, Soil water, Ecosystem and Phenology.
Carbon cycle is the focus of his Ecosystem research.
His Phenology study results in a more complete grasp of Ecology.
His Canopy research is multidisciplinary, incorporating perspectives in Photosynthetic capacity, Temperate deciduous forest, Deciduous and Horticulture.
In his work, Soil horizon and Tree species is strongly intertwined with Atmospheric sciences, which is a subfield of Deciduous.
His work in Forest floor addresses issues such as Water content, which are connected to fields such as Carbon sequestration, Forest ecology, Plant litter, Soil science and Soil respiration.
