Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Photosynthesis

His primary areas of investigation include Botany, Thallus, Lichen, Lobaria pulmonaria and Parietin. Botany is often connected to Horticulture in his work. His Thallus research is multidisciplinary, incorporating perspectives in Photosynthesis and Photosystem II.

His Lichen study combines topics in areas such as Epiphyte and Taiga. His research brings together the fields of Pulmonaria and Lobaria pulmonaria. His work carried out in the field of Parietin brings together such families of science as Photoprotection, Xanthoria elegans and Photosynthetically active radiation.

His most cited work include:

  • UV‐induction of sun‐screening pigments in lichens (162 citations)
  • Differences in the susceptibility to light stress between epiphytic lichens of ancient and young boreal forest stands (159 citations)
  • Phenolic contents and other health and sensory related properties of apple fruit (Malus domestica Borkh., cv. Aroma): Effect of postharvest UV-B irradiation (156 citations)

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

His primary areas of study are Botany, Lichen, Lobaria pulmonaria, Thallus and Horticulture. Photosynthesis, Chlorophyll fluorescence, Photoinhibition, Chlorophyll and Parietin are the subjects of his Botany studies. His Lichen research incorporates themes from Environmental chemistry and Epiphyte.

His Lobaria pulmonaria research is multidisciplinary, incorporating elements of Parmelia sulcata and Pulmonaria. His work on Foliose lichen as part of general Thallus research is often related to Trebouxia, thus linking different fields of science. His work on Powdery mildew, Plant morphology, Dry weight and Cultivar as part of general Horticulture study is frequently linked to Light intensity, therefore connecting diverse disciplines of science.

He most often published in these fields:

  • Botany (67.71%)
  • Lichen (44.79%)
  • Lobaria pulmonaria (34.38%)

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

  • Lichen (44.79%)
  • Botany (67.71%)
  • Horticulture (26.04%)

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

Lichen, Botany, Horticulture, Chlorophyll fluorescence and Photosynthesis are his primary areas of study. Knut Asbjørn Solhaug studies Lichen, namely Lobaria pulmonaria. His research ties Abiotic component and Botany together.

When carried out as part of a general Horticulture research project, his work on Plant morphology, Cultivar and Controlled environment chamber is frequently linked to work in Relative growth rate and Ultraviolet, therefore connecting diverse disciplines of study. His studies deal with areas such as Lipid peroxidation and Desiccation as well as Photosynthesis. As a part of the same scientific study, Knut Asbjørn Solhaug usually deals with the Photoinhibition, concentrating on Photoprotection and frequently concerns with Usnic acid, Vulpinic acid, Parietin and Letharia vulpina.

Between 2017 and 2021, his most popular works were:

  • Rapid resurrection of chlorolichens in humid air: specific thallus mass drives rehydration and reactivation kinetics (23 citations)
  • Modes of action and adverse effects of gamma radiation in an aquatic macrophyte Lemna minor. (10 citations)
  • Low-light recovery effects on assessment of photoinhibition with chlorophyll fluorescence in lichens (9 citations)

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

  • Botany
  • Ecology
  • Photosynthesis

His primary scientific interests are in Lichen, Environmental chemistry, Chlorophyll fluorescence, Photosynthesis and Photoinhibition. Lichen is a subfield of Botany that Knut Asbjørn Solhaug investigates. His Botany research integrates issues from Montane ecology and Abiotic component.

Knut Asbjørn Solhaug has researched Photosynthesis in several fields, including Lipid peroxidation and Reactive oxygen species. His study in Photoinhibition is interdisciplinary in nature, drawing from both Lobaria pulmonaria, Pseudocyphellaria and Cetraria. The study incorporates disciplines such as Green algae, Mode of action, Chlorophyll and Oxidative phosphorylation in addition to Photosystem II.
