Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Genus
  • Ecology

His main research concerns Botany, Ecology, Phylogenetic tree, Evolutionary biology and Phylogenetics. The concepts of his Botany study are interwoven with issues in Clade, Monophyly and Molecular phylogenetics. His Monophyly research is multidisciplinary, incorporating perspectives in Cleomaceae and NdhF.

The various areas that Kenneth J. Sytsma examines in his Ecology study include Biological dispersal, Vicariance and Bromelioideae. His work on Chloroplast DNA and Molecular evolution as part of general Phylogenetic tree research is often related to Combinatorics, thus linking different fields of science. His Evolutionary biology study combines topics from a wide range of disciplines, such as Onagraceae, Saxifragales, Austrobaileyales, Nymphaeales and Amborellaceae.

His most cited work include:

  • Angiosperm phylogeny: 17 genes, 640 taxa (499 citations)
  • Molecular evolution and adaptive radiation (389 citations)
  • Angiosperm Phylogeny Inferred from 18S Ribosomal DNA Sequences (367 citations)

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

Kenneth J. Sytsma mostly deals with Botany, Phylogenetic tree, Evolutionary biology, Monophyly and Phylogenetics. His Botany research includes themes of Chloroplast DNA and NdhF. The Phylogenetic tree study combines topics in areas such as Zoology, Ecology and Nuclear gene.

His Ecology research includes elements of Biological dispersal, Lineage and Vicariance. As a part of the same scientific study, Kenneth J. Sytsma usually deals with the Evolutionary biology, concentrating on Molecular phylogenetics and frequently concerns with Systematics. In his work, Rosidae is strongly intertwined with Sister group, which is a subfield of Monophyly.

He most often published in these fields:

  • Botany (42.31%)
  • Phylogenetic tree (33.85%)
  • Evolutionary biology (30.00%)

What were the highlights of his more recent work (between 2013-2021)?

  • Ecology (25.38%)
  • Phylogenetic tree (33.85%)
  • Clade (18.46%)

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

His primary scientific interests are in Ecology, Phylogenetic tree, Clade, Evolutionary biology and Phylogenetics. His work is dedicated to discovering how Ecology, Biological dispersal are connected with Crown group, Capparaceae, Brassicaceae and Vicariance and other disciplines. His Phylogenetic tree study integrates concerns from other disciplines, such as Lamiaceae, Salvia, Botany, Niche differentiation and Plant community.

His Botany research is multidisciplinary, incorporating elements of Zoology and Chloroplast capture. His studies deal with areas such as Polemoniaceae, NdhF, Genome and Vochysiaceae as well as Evolutionary biology. His Phylogenetics study combines topics in areas such as Pollination, Pollinator and Morphometrics.

Between 2013 and 2021, his most popular works were:

  • Adaptive radiation, correlated and contingent evolution, and net species diversification in Bromeliaceae (201 citations)
  • Divergence times, historical biogeography, and shifts in speciation rates of Myrtales (70 citations)
  • Salvia united: The greatest good for the greatest number (55 citations)

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

  • Genus
  • Ecology
  • Botany

His primary areas of investigation include Ecology, Clade, Evolutionary biology, Phylogenetic tree and Taxon. His research brings together the fields of Lineage and Ecology. In his work, he performs multidisciplinary research in Clade and Brassicales.

Kenneth J. Sytsma interconnects Ericales, Phylogenetics, Cladogenesis, Genome and Phylogenomics in the investigation of issues within Evolutionary biology. His work in the fields of Arbutoideae overlaps with other areas such as Crypteroniaceae. Kenneth J. Sytsma has researched Taxon in several fields, including Vicariance and NdhF.
