Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Ecosystem
  • Botany

His primary areas of study are Ecology, Agronomy, Soil water, Canopy and Hydraulic redistribution. His study in the field of Ecosystem, Biota and Periphyton also crosses realms of Snowmelt. Ronald J. Ryel studies Growing season, a branch of Agronomy.

His studies deal with areas such as Water use and Water content as well as Soil water. His research in Canopy intersects with topics in Photosynthesis, Forestry, Tropical rainforest and Interception. His biological study deals with issues like Water potential, which deal with fields such as Soil horizon.

His most cited work include:

  • Hydraulic redistribution in a stand of Artemisia tridentata: Evaluation of benefits to transpiration assessed with a simulation model (186 citations)
  • Herbivory of Leaf-Cutting Ants: A Case Study on Atta colombica in the Tropical Rainforest of Panama (169 citations)
  • Herbivory of Leaf-Cutting Ants (148 citations)

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

Ecology, Botany, Agronomy, Canopy and Soil water are his primary areas of study. His study in Ecosystem, Herbivore, Species richness, Range and Ecological succession are all subfields of Ecology. His Ecosystem study combines topics in areas such as Biodiversity and Vegetation.

His Agronomy research is multidisciplinary, incorporating perspectives in Shrub and Nutrient. His Canopy research is multidisciplinary, relying on both Photosynthesis, Forest floor and Interception. His Soil water research is multidisciplinary, incorporating elements of Water use and Water content.

He most often published in these fields:

  • Ecology (43.36%)
  • Botany (25.66%)
  • Agronomy (23.89%)

What were the highlights of his more recent work (between 2011-2017)?

  • Ecology (43.36%)
  • Botany (25.66%)
  • Range (6.19%)

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

The scientist’s investigation covers issues in Ecology, Botany, Range, Acclimatization and Quaking Aspen. Species distribution, Disturbance, Woody plant and Shrub are the subjects of his Ecology studies. His Botany study frequently involves adjacent topics like Hydraulic conductivity.

Ronald J. Ryel has included themes like Agroforestry, Herbivore, Riparian zone, Seral community and Adaptive management in his Range study. The concepts of his Acclimatization study are interwoven with issues in Transmittance, Chlorophyll, Chlorophyll fluorescence and Ultraviolet. Ronald J. Ryel usually deals with Quaking Aspen and limits it to topics linked to Species richness and Gene pool, Genetic distance, Genetic diversity, Abundance and Breeding bird survey.

Between 2011 and 2017, his most popular works were:

  • Continental-scale assessment of genetic diversity and population structure in quaking aspen (Populus tremuloides) (51 citations)
  • Widespread triploidy in Western North American aspen (Populus tremuloides). (48 citations)
  • Influence of sampling frequency on estimation of annual total phosphorus and total suspended solids loads (42 citations)
