  • Ecology
  • Botany
  • Ecosystem

His scientific interests lie mostly in Ozone, Botany, Agronomy, Pollutant and Ambient ozone. His study in the field of Tropospheric ozone also crosses realms of Monitoring data. William J. Manning combines subjects such as Carbon dioxide and Horticulture with his study of Botany.

His study on Cultivar is often connected to Centaurea nigra and Native plant as part of broader study in Agronomy. His Pollutant research includes themes of Air pollution and Atmosphere. His Air pollution research integrates issues from Meteorology and Environmental protection.

His most cited work include:

  • Atmospheric ozone: Formation and effects on vegetation (347 citations)
  • The impact of ozone on assimilate partitioning in plants: A review (318 citations)
  • Climate change: potential effects of increased atmospheric carbon dioxide (CO2), ozone (O3), and ultraviolet-B (UV-B) radiation on plant diseases. (289 citations)

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

The scientist’s investigation covers issues in Ozone, Botany, Horticulture, Agronomy and Cultivar. His work deals with themes such as Environmental chemistry, Air pollution and Vegetation, which intersect with Ozone. His study on Air pollution also encompasses disciplines like

  • Pollutant together with Atmosphere,
  • Air quality index that intertwine with fields like Ecosystem and Environmental protection.

William J. Manning usually deals with Botany and limits it to topics linked to Ethylene diurea and Antiozonant and Biomonitoring. His Horticulture research is multidisciplinary, incorporating perspectives in Photosynthesis and Growing season. His Cultivar research is multidisciplinary, relying on both Botrytis cinerea, Plant growth and Yield.

He most often published in these fields:

  • Ozone (46.28%)
  • Botany (37.19%)
  • Horticulture (33.06%)

What were the highlights of his more recent work (between 2013-2020)?

  • Horticulture (33.06%)
  • Ozone (46.28%)
  • Photosynthesis (10.74%)

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

His primary areas of study are Horticulture, Ozone, Photosynthesis, Botany and Growing season. His work on Red maple as part of general Horticulture research is frequently linked to Resorption, thereby connecting diverse disciplines of science. His Ozone study integrates concerns from other disciplines, such as Mode of action and Stomatal conductance.

His biological study spans a wide range of topics, including Biomass, Maple and Chlorophyll a. His work focuses on many connections between Botany and other disciplines, such as Ethylene diurea, that overlap with his field of interest in Nitrogen fertilizer and Environmental chemistry. As a member of one scientific family, William J. Manning mostly works in the field of Growing season, focusing on Abscission and, on occasion, Plant physiology and Fumigation.

Between 2013 and 2020, his most popular works were:

  • Ozone levels in European and USA cities are increasing more than at rural sites, while peak values are decreasing. (137 citations)
  • Projected Carbon Dioxide to Increase Grass Pollen and Allergen Exposure Despite Higher Ozone Levels (62 citations)
  • Assessing the effects of ambient ozone in China on snap bean genotypes by using ethylenediurea (EDU). (40 citations)

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

  • Ecology
  • Botany
  • Ecosystem

William J. Manning mainly investigates Botany, Ozone, Stomatal conductance, Tropospheric ozone and Agronomy. His study in Botany is interdisciplinary in nature, drawing from both Ethylene diurea, Carbon dioxide and Animal science. His Stomatal conductance study often links to related topics such as Horticulture.

The Tropospheric ozone study combines topics in areas such as Vegetation, Air quality index and Environmental protection. His work on Plant breeding, Panicle, Fumigation and Growing season as part of general Agronomy study is frequently connected to Oryza, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. His Growing season research incorporates elements of Photosynthesis and Phaseolus.
