Overview

What is he best known for?

The fields of study he is best known for:

  • Genus
  • Botany
  • Flowering plant

William L. Crepet mainly investigates Botany, Pollination, Ecology, Taxon and Cretaceous. His work in Botany is not limited to one particular discipline; it also encompasses Sister group. His research in Pollination intersects with topics in Insect, Ecology, Sexual reproduction and Resistance.

His work on Paleogene expands to the thematically related Ecology. His Taxon research is multidisciplinary, incorporating elements of Tricolpate, Clade and Pollinator. His Cretaceous study combines topics from a wide range of disciplines, such as Lineage and Molecular phylogenetics.

His most cited work include:

  • A reevaluation of seed plant phylogeny. (265 citations)
  • Fossil evidence and phylogeny: the age of major angiosperm clades based on mesofossil and macrofossil evidence from Cretaceous deposits. (212 citations)
  • Darwin’s second “abominable mystery”: Why are there so many angiosperm species? (145 citations)

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

William L. Crepet mostly deals with Botany, Pollen, Ecology, Cretaceous and Paleontology. His study ties his expertise on Ericales together with the subject of Botany. In general Pollen study, his work on Palynology often relates to the realm of Subfamily, thereby connecting several areas of interest.

His Ecology research includes elements of Paleogene and Morphology. His Cretaceous study deals with Genus intersecting with Synapomorphy. In his research, Calycanthaceae and Sister group is intimately related to Laurales, which falls under the overarching field of Paleontology.

He most often published in these fields:

  • Botany (61.11%)
  • Pollen (28.89%)
  • Ecology (26.67%)

What were the highlights of his more recent work (between 2008-2021)?

  • Taxon (24.44%)
  • Paleontology (24.44%)
  • Botany (61.11%)

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

His scientific interests lie mostly in Taxon, Paleontology, Botany, Cretaceous and Evolutionary biology. The concepts of his Taxon study are interwoven with issues in Sensu, Clade, Fossil Record and Morphology. The Biogeography, Structural basin and Neogene research William L. Crepet does as part of his general Paleontology study is frequently linked to other disciplines of science, such as Andean plateau and Elevation, therefore creating a link between diverse domains of science.

His work on Botany is being expanded to include thematically relevant topics such as Ericales. His studies in Cretaceous integrate themes in fields like Inflorescence, Genus and Cupressaceae. His work on Mosaic evolution as part of general Evolutionary biology research is frequently linked to Paleobotany, bridging the gap between disciplines.

Between 2008 and 2021, his most popular works were:

  • Darwin’s second “abominable mystery”: Why are there so many angiosperm species? (145 citations)
  • Is the anthophyte hypothesis alive and well? New evidence from the reproductive structures of Bennettitales. (67 citations)
  • Pentapetalum trifasciculandricus gen. et sp. nov., a thealean fossil flower from the Raritan Formation, New Jersey, USA (Turonian, Late Cretaceous). (27 citations)

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

  • Genus
  • Botany
  • Flowering plant

The scientist’s investigation covers issues in Botany, Ericales, Taxon, Sister group and Paleontology. His work in the fields of Ovule overlaps with other areas such as Theaceae. His Ericales research incorporates elements of Sensu, Clade, Stewartia and Cladistics.

William L. Crepet has researched Taxon in several fields, including Atherospermataceae, Monimiaceae, Biogeography and Morphology. His study in Sister group is interdisciplinary in nature, drawing from both Cycadeoidea, Pollen, Gynoecium and Fern. His Paleontology research incorporates themes from Inflorescence, Laurales and Genus.
