  • Improved Equations for the Prediction of Seed Longevity (438 citations)

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

Richard Ellis mostly deals with Agronomy, Horticulture, Botany, Germination and Water content. Sowing, Cultivar, Poaceae, Crop and Anthesis are among the areas of Agronomy where Richard Ellis concentrates his study. Richard Ellis regularly ties together related areas like Environmental factor in his Horticulture studies.

Richard Ellis combines subjects such as Desiccation and Seedling with his study of Germination. His work on Desiccation deals in particular with Desiccation tolerance, Recalcitrant seed and Orthodox seed. Among his research on Water content, you can see a combination of other fields of science like Longevity and Relative humidity.

He most often published in these fields:

  • Agronomy (36.34%)
  • Horticulture (32.10%)
  • Botany (25.46%)

What were the highlights of his more recent work (between 2006-2020)?

  • Astrophysics (19.10%)
  • Agronomy (36.34%)
  • Germination (25.20%)

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

His main research concerns Astrophysics, Agronomy, Germination, Horticulture and Galaxy. His work in the fields of Astrophysics, such as Supernova, Galaxy cluster and Hubble Deep Field, intersects with other areas such as Host. His Agronomy research is multidisciplinary, incorporating perspectives in Livestock and Water content.

His Germination study improves the overall literature in Botany. His work on Yield as part of general Horticulture study is frequently connected to Longevity, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. His study in the field of Redshift also crosses realms of Tully–Fisher relation.

Between 2006 and 2020, his most popular works were:

  • Extragalactic Science, Cosmology and Galactic Archaeology with the Subaru Prime Focus Spectrograph (PFS) (333 citations)
  • The intense starburst HDF 850.1 in a galaxy overdensity at z ≈ 5.2 in the Hubble Deep Field (239 citations)
  • Resolved Spectroscopy of Gravitationally-Lensed Galaxies: Recovering Coherent Velocity Fields in Sub-Luminous z~2-3 Galaxies (117 citations)

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

  • Botany
  • Ecology
  • Agriculture

His primary scientific interests are in Agronomy, Germination, Botany, Horticulture and Longevity. His studies deal with areas such as Quality development and Quality management as well as Agronomy. His work on Desiccation and Galanthus nivalis as part of general Botany research is frequently linked to Sindora siamensis, Cananga odorata and Cassia javanica, bridging the gap between disciplines.

His work on Peltophorum and Peltophorum pterocarpum as part of general Horticulture study is frequently linked to Hopea odorata, bridging the gap between disciplines. His study in Water content is interdisciplinary in nature, drawing from both Sesamum and Temperate climate. His Desiccation tolerance research is multidisciplinary, relying on both Inflorescence, Outcrossing, Dry weight and Point of delivery.
