Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Botany
  • Ecosystem

His primary areas of study are Photosynthesis, Botany, Lichen, Ecology and Atmospheric sciences. His Photosynthesis research is multidisciplinary, relying on both Productivity, Carbon dioxide and Water vapor. In his study, Respiration and Guard cell is inextricably linked to Horticulture, which falls within the broad field of Botany.

His Lichen study combines topics in areas such as Snow and Thallus. His research combines Relative humidity and Ecology. His Atmospheric sciences research includes elements of Precipitation and Water content.

His most cited work include:

  • Responses of stomata to changes in humidity. (376 citations)
  • Water and Plant Life (169 citations)
  • Long-term productivity in the cryptoendolithic microbial community of the Ross Desert, Antarctica. (143 citations)

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

Botany, Lichen, Ecology, Photosynthesis and Horticulture are his primary areas of study. His study on Botany is mostly dedicated to connecting different topics, such as Water content. His Lichen study integrates concerns from other disciplines, such as Dew, Thallus, Snow, Vegetation and Moisture.

His work on Habitat, Productivity, Ecosystem and Usnea as part of general Ecology research is frequently linked to Desert, bridging the gap between disciplines. His work on Ecophysiology as part of general Photosynthesis research is often related to Prunus armeniaca, thus linking different fields of science. The concepts of his Horticulture study are interwoven with issues in Air humidity, Growing season and Respiration.

He most often published in these fields:

  • Botany (46.40%)
  • Lichen (40.00%)
  • Ecology (33.60%)

What were the highlights of his more recent work (between 1996-2013)?

  • Ecology (33.60%)
  • Botany (46.40%)
  • Lichen (40.00%)

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

His main research concerns Ecology, Botany, Lichen, Ecosystem and Transpiration. His study ties his expertise on Crust together with the subject of Ecology. His Photosynthesis, Alnus glutinosa, Alder, Guard cell and Sexual reproduction study are his primary interests in Botany.

His Photosynthesis study incorporates themes from Xanthoria and Chlorophyll a. His Lichen study combines topics from a wide range of disciplines, such as Flora, Ecology, Thallus and Snow, Meltwater. The various areas that Ludger Kappen examines in his Transpiration study include Evapotranspiration, Horticulture and Stomatal conductance.

Between 1996 and 2013, his most popular works were:

  • Some aspects of the great success of lichens in Antarctica (109 citations)
  • Photosynthesis of Lichens from Antarctica (99 citations)
  • The ratio of transpiration versus evaporation in a reed belt as influenced by weather conditions (87 citations)

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

  • Ecology
  • Botany
  • Ecosystem

The scientist’s investigation covers issues in Botany, Lichen, Ecology, Transpiration and Photosynthesis. His Botany research incorporates elements of Condensation, Relative humidity and Analytical chemistry. His Lichen research incorporates themes from Global biodiversity, Peninsula, Snow, Meltwater and Vegetation.

His Ecology research integrates issues from Bay and Shetland. Ludger Kappen has included themes like Stomatal conductance, Water vapor, Humidity and Aegopodium in his Transpiration study. His Photosynthesis research is multidisciplinary, incorporating perspectives in Xanthoria, Carbon dioxide and Chlorophyll a.
