Overview

What is he best known for?

The fields of study he is best known for:

Botany
Ecology
Photosynthesis

Botany, Xanthophyll, Photosynthesis, Antheraxanthin and Photoprotection are his primary areas of study. His Botany study combines topics from a wide range of disciplines, such as Thylakoid, Antioxidant and Water content. Xanthophyll is often connected to Photosystem II in his work.

His Photosystem II research incorporates elements of Acclimatization, Chlorophyll fluorescence and Analytical chemistry. Barry A. Logan usually deals with Photosynthesis and limits it to topics linked to Chlorophyll and Spinacia, Spinach, Food science and Quenching. His multidisciplinary approach integrates Photoprotection and Glutathione reductase in his work.

His most cited work include:

Using chlorophyll fluorescence to assess the fraction of absorbed light allocated to thermal dissipation of excess excitation (633 citations)
Energy dissipation and radical scavenging by the plant phenylpropanoid pathway. (330 citations)
Acclimation of Foliar Antioxidant Systems to Growth Irradiance in Three Broad-Leaved Evergreen Species. (274 citations)

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

Barry A. Logan focuses on Botany, Photosynthesis, Xanthophyll, Chlorophyll fluorescence and Photoprotection. His Photosystem II, Acclimatization and Zeaxanthin study, which is part of a larger body of work in Botany, is frequently linked to Light intensity, bridging the gap between disciplines. As part of the same scientific family, he usually focuses on Photosynthesis, concentrating on Chlorophyll and intersecting with Growing season.

In his study, which falls under the umbrella issue of Xanthophyll, Tsuga is strongly linked to Understory. His research integrates issues of Quenching, Biological system and Chlorophyll a in his study of Chlorophyll fluorescence. Field conditions and Electron transport chain is closely connected to Biophysics in his research, which is encompassed under the umbrella topic of Photoprotection.

He most often published in these fields:

Botany (67.01%)
Photosynthesis (61.86%)
Xanthophyll (28.87%)

What were the highlights of his more recent work (between 2017-2021)?

Environmental science (18.56%)
Photosynthesis (61.86%)
Evergreen forest (6.19%)

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

His scientific interests lie mostly in Environmental science, Photosynthesis, Evergreen forest, Evergreen and Global change. Photosynthesis is a subfield of Botany that Barry A. Logan explores. In the subject of general Botany, his work in Podocarpaceae and Thallus is often linked to Prumnopitys taxifolia and Proline, thereby combining diverse domains of study.

Barry A. Logan has researched Evergreen in several fields, including Photochemical Reflectance Index, Canopy and Dormancy. Barry A. Logan interconnects Biodiversity, Salt marsh and Stomatal conductance in the investigation of issues within Global change. His Subalpine forest research is multidisciplinary, incorporating elements of Quenching and Climate change.

Between 2017 and 2021, his most popular works were:

Mechanistic evidence for tracking the seasonality of photosynthesis with solar-induced fluorescence (46 citations)
When are foliar anthocyanins useful to plants? Re-evaluation of the photoprotection hypothesis using Arabidopsis thaliana mutants that differ in anthocyanin accumulation (45 citations)
Limitations to winter and spring photosynthesis of a Rocky Mountain subalpine forest (32 citations)

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

Botany
Ecology
Photosynthesis

Barry A. Logan mainly investigates Environmental science, Evergreen, Horticulture, Photoprotection and Xanthophyll. His Horticulture study incorporates themes from Action spectrum, Photoinhibition, Photosystem II and Carotenoid. His work carried out in the field of Carotenoid brings together such families of science as Photosynthesis and Chlorophyll fluorescence.

His study on Photosynthetic capacity is often connected to Water transport as part of broader study in Photosynthesis. The various areas that Barry A. Logan examines in his Photoprotection study include Chlorophyll and Anthocyanin. The Primary production study combines topics in areas such as Photochemical Reflectance Index, Quenching and Climate change.
