Overview

What is he best known for?

The fields of study he is best known for:

  • Genus
  • Botany
  • Ecology

His primary scientific interests are in Botany, Monophyly, Evolutionary biology, Subgenus and Tribe. His work on Poaceae as part of general Botany study is frequently connected to Spartina maritima, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. His Monophyly research is multidisciplinary, incorporating perspectives in Citreae, Citrus medica and Sensu.

The various areas that Randall J. Bayer examines in his Evolutionary biology study include Peristome, Orthotrichum, Intergenic spacer and Maximum parsimony. Randall J. Bayer has included themes like Taxon and Cladistics in his Subgenus study. His Tribe research integrates issues from Craspedia, Ozothamnus, Gnaphalieae, Calocephalus and Asteroideae.

His most cited work include:

  • Everywhere but Antarctica: using a supertree to understand the diversity and distribution of the Compositae. (220 citations)
  • A molecular phylogeny of the orange subfamily(Rutaceae: Aurantioideae) using nine cpDNA sequences (132 citations)
  • Phylogenetic relationships in Lupinus (Fabaceae: Papilionoideae) based on internal transcribed spacer sequences (ITS) of nuclear ribosomal DNA. (127 citations)

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

Randall J. Bayer mostly deals with Botany, Monophyly, Asteraceae, Inuleae and Polyploid. His Botany study integrates concerns from other disciplines, such as Paraphyly and Clade. His Paraphyly study combines topics in areas such as Acacia, Mimosoideae, Subgenus and Molecular phylogenetics.

His work carried out in the field of Monophyly brings together such families of science as Evolutionary biology, Internal transcribed spacer and Genus, Tribe, Gnaphalieae. Randall J. Bayer interconnects Character evolution and Gene flow in the investigation of issues within Evolutionary biology. His study in the field of Antennaria rosea also crosses realms of Population genetics.

He most often published in these fields:

  • Botany (81.94%)
  • Monophyly (27.78%)
  • Asteraceae (27.78%)

What were the highlights of his more recent work (between 2000-2020)?

  • Botany (81.94%)
  • Monophyly (27.78%)
  • Molecular phylogenetics (11.11%)

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

His primary areas of study are Botany, Monophyly, Molecular phylogenetics, Paraphyly and Systematics. His studies in Botany integrate themes in fields like Asteroideae and Polyphyly. His Monophyly research includes themes of Evolutionary biology, Genus, Tribe and Acacia, Mimosoideae.

His Tribe research is multidisciplinary, incorporating elements of Asteraceae, Heliantheae, Ozothamnus, Calocephalus and Eupatorium. The concepts of his Molecular phylogenetics study are interwoven with issues in Reticulate evolution, Lineage and Introgression. The Taxon study combines topics in areas such as Taxonomy and Internal transcribed spacer.

Between 2000 and 2020, his most popular works were:

  • Everywhere but Antarctica: using a supertree to understand the diversity and distribution of the Compositae. (220 citations)
  • A molecular phylogeny of the orange subfamily(Rutaceae: Aurantioideae) using nine cpDNA sequences (132 citations)
  • Molecular phylogeny of hybridizing species from the genus Spartina Schreb. (Poaceae). (107 citations)

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

  • Genus
  • Botany
  • Ecology

Randall J. Bayer mainly investigates Botany, Monophyly, Tribe, Subgenus and Systematics. His Molecular phylogenetics research extends to the thematically linked field of Botany. His research in Molecular phylogenetics intersects with topics in Reticulate evolution, Lineage and Introgression.

His Monophyly study incorporates themes from Craspedia, Ozothamnus, Gnaphalieae, Calocephalus and Asteroideae. His Taxon research incorporates themes from Zoology, Taxonomy and Cladistics. His Eupatorieae research is multidisciplinary, relying on both Vernonieae, Liabeae, Heliantheae and Eupatorium.
