Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Botany
  • Ecosystem

Ragan M. Callaway mainly focuses on Ecology, Competition, Botany, Plant community and Introduced species. His Ecology research integrates issues from Facilitation and Allelopathy. He has included themes like Resource and Interspecific competition in his Competition study.

His Botany study integrates concerns from other disciplines, such as Rhizosphere and Symbiosis. His work deals with themes such as Biomass, Global biodiversity and Plant ecology, which intersect with Plant community. His Introduced species research includes themes of Agronomy and Invasive species.

His most cited work include:

  • Positive interactions in communities. (2445 citations)
  • Competition and facilitation: a synthetic approach to interactions in plant communities (1550 citations)
  • Positive interactions among plants (1373 citations)

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

His main research concerns Ecology, Botany, Competition, Invasive species and Introduced species. As a part of the same scientific family, Ragan M. Callaway mostly works in the field of Ecology, focusing on Facilitation and, on occasion, Ecological systems theory. His Competition research focuses on Interspecific competition and how it connects with Intraspecific competition.

His Invasive species research focuses on subjects like Soil biology, which are linked to Rhizosphere. In the field of Introduced species, his study on Centaurea stoebe overlaps with subjects such as Acer platanoides. He focuses mostly in the field of Plant community, narrowing it down to matters related to Biodiversity and, in some cases, Ecosystem.

He most often published in these fields:

  • Ecology (75.68%)
  • Botany (30.48%)
  • Competition (24.32%)

What were the highlights of his more recent work (between 2015-2021)?

  • Ecology (75.68%)
  • Invasive species (24.32%)
  • Competition (24.32%)

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

His primary areas of investigation include Ecology, Invasive species, Competition, Botany and Introduced species. His study involves Range, Species richness, Native plant, Interspecific competition and Biomass, a branch of Ecology. His Invasive species research integrates issues from Plant ecology, Herbivore and Arid.

His work in Competition tackles topics such as Shoot which are related to areas like Priority effect, Senecio, Bromus marginatus and Abiotic component. Ragan M. Callaway combines subjects such as Ecological niche and Sequence analysis with his study of Botany. His studies deal with areas such as Abundance, Habitat, Pinus contorta, Eco evolutionary and Bromus tectorum as well as Introduced species.

Between 2015 and 2021, his most popular works were:

  • The Overlooked Role of Facilitation in Biodiversity Experiments (96 citations)
  • Relative importance of competition and plant–soil feedback, their synergy, context dependency and implications for coexistence (80 citations)
  • The Mechanisms and Consequences of Interspecific Competition Among Plants (72 citations)

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

  • Ecology
  • Botany
  • Habitat

Ragan M. Callaway mostly deals with Ecology, Introduced species, Botany, Competition and Invasive species. He integrates Ecology with Competitor analysis in his research. His work carried out in the field of Introduced species brings together such families of science as Pinus contorta, Canopy and Eco evolutionary.

His study in the field of Echium plantagineum and Seedling also crosses realms of Echium and Elevation. The study incorporates disciplines such as Resistance and Native plant in addition to Invasive species. Ragan M. Callaway has included themes like Plant ecology, Pseudoroegneria spicata and Stoebe, Centaurea stoebe in his Native plant study.
