Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Enzyme

His main research concerns Botany, Photosynthesis, Abies balsamea, Horticulture and Chlorophyll. Many of his studies on Botany involve topics that are commonly interrelated, such as Reflectivity. Graeme P. Berlyn combines subjects such as Soil science, Absorbance, Photosynthetic pigment and Chlorophyll b with his study of Reflectivity.

His Abies balsamea research focuses on subjects like Chlorophyll fluorescence, which are linked to Fern, Sorbus americana, Balsam and Temperate climate. His Horticulture research is multidisciplinary, incorporating elements of Epidermis and Betulaceae. His studies examine the connections between Chlorophyll and genetics, as well as such issues in Chlorophyll a, with regards to Red edge.

His most cited work include:

  • Botanical Microtechnique and Cytochemistry (959 citations)
  • An evaluation of noninvasive methods to estimate foliar chlorophyll content (727 citations)
  • Hemlock Woolly Adelgid (Homoptera: Adelgidae): Stylet Bundle Insertion and Feeding Sites (189 citations)

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

Graeme P. Berlyn mainly investigates Botany, Horticulture, Photosynthesis, Nuclear DNA and DNA. His Botany research focuses on Cuticle, Chlorophyll, Pinus , Abies balsamea and Photochemical Reflectance Index. Chlorophyll is closely attributed to Chlorophyll a in his study.

His study in the field of Germination is also linked to topics like Elevation and Water content. His Photosynthesis study combines topics in areas such as Canopy and Betulaceae. His DNA study is concerned with Biochemistry in general.

He most often published in these fields:

  • Botany (52.38%)
  • Horticulture (13.10%)
  • Photosynthesis (10.71%)

What were the highlights of his more recent work (between 2006-2021)?

  • Transpiration (8.33%)
  • Seagrass (5.95%)
  • Subtropics (4.76%)

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

Graeme P. Berlyn mostly deals with Transpiration, Seagrass, Subtropics, Agronomy and Biomass. His research integrates issues of Stomatal conductance, Pinaceae, Ecophysiology and Sowing in his study of Transpiration. His Stomatal conductance study is concerned with the field of Botany as a whole.

In general Seagrass, his work in Blue carbon is often linked to Southeast asian linking many areas of study. His Agronomy research integrates issues from Greening, Evapotranspiration and Fraxinus chinensis. His biological study spans a wide range of topics, including Shoot and Animal science.

Between 2006 and 2021, his most popular works were:

  • Drought response of two Mexican oak species, Quercus laceyi and Q. sideroxyla (Fagaceae), in relation to elevational position (44 citations)
  • Spectral reflectance of the seagrasses: Thalassia testudinum, Halodule wrightii, Syringodium filiforme and five marine algae (36 citations)
  • Variability in needle morphology and water status of Pinus cembroides across an elevational gradient in the Davis Mountains of west Texas, USA1 (16 citations)

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

  • Botany
  • Ecology
  • Enzyme

His primary areas of study are Water content, Ecology, Pinaceae, Transpiration and Thalassia testudinum. His Pinaceae research includes elements of Range and Pinus cembroides. His Transpiration research incorporates themes from Photosynthetic capacity, Ecophysiology, Pinus lambertiana and Stratification.

His study explores the link between Thalassia testudinum and topics such as Halodule that cross with problems in Chlorophyll a, Light intensity and Zostera marina. His study connects Botany and Syringodium filiforme. Much of his study explores Botany relationship to Horticulture.
