Overview

What is he best known for?

The fields of study he is best known for:

  • Genus
  • Botany
  • Paleontology

Kaj Raunsgaard Pedersen spends much of his time researching Botany, Cretaceous, Amborellaceae, Nymphaeales and Austrobaileyales. His study in the field of Chloranthaceae also crosses realms of Acorus. His work in Chloranthaceae covers topics such as Ecology which are related to areas like Trimeniaceae and Aptian.

His Cretaceous research is under the purview of Paleontology. His work in the fields of Mesozoic and Biostratigraphy overlaps with other areas such as Diversification. His study looks at the intersection of Amborellaceae and topics like Hydatellaceae with Illiciales, Nymphaeaceae and Cabombaceae.

His most cited work include:

  • The origin and early diversification of angiosperms (562 citations)
  • Early Flowers and Angiosperm Evolution (308 citations)
  • Early angiosperm diversification : The diversity of pollen associated with angiosperm reproductive structures in early Cretaceous floras from Portugal (181 citations)

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

His primary areas of study are Botany, Cretaceous, Pollen, Paleontology and Ecology. His study in Botany focuses on Stamen, Gynoecium, Chloranthaceae, Genus and Potomac Group. His studies deal with areas such as Ovule, Flora, Mesozoic and Taxon as well as Cretaceous.

The Tricolpate and Hypanthium research Kaj Raunsgaard Pedersen does as part of his general Pollen study is frequently linked to other disciplines of science, such as Pollen wall and Sporangium, therefore creating a link between diverse domains of science. In the subject of general Paleontology, his work in Aptian and Cenomanian is often linked to Microscopy and Synchrotron radiation, thereby combining diverse domains of study. Kaj Raunsgaard Pedersen interconnects Caytoniales and Bennettitales in the investigation of issues within Ecology.

He most often published in these fields:

  • Botany (74.49%)
  • Cretaceous (56.12%)
  • Pollen (27.55%)

What were the highlights of his more recent work (between 2016-2021)?

  • Cretaceous (56.12%)
  • Botany (74.49%)
  • Ecology (23.47%)

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

Kaj Raunsgaard Pedersen mainly investigates Cretaceous, Botany, Ecology, Paleontology and Genus. By researching both Cretaceous and Extant taxon, Kaj Raunsgaard Pedersen produces research that crosses academic boundaries. The study incorporates disciplines such as Magnoliids and Magnoliales in addition to Botany.

His Paleontology study frequently links to adjacent areas such as Laurales. His Biodiversity study incorporates themes from Austrobaileyales and Nymphaeales. His research in Flora intersects with topics in Potomac Group and Aptian.

Between 2016 and 2021, his most popular works were:

  • Palaeobotanical redux: revisiting the age of the angiosperms. (76 citations)
  • Paisia, an Early Cretaceous eudicot angiosperm flower with pantoporate pollen from Portugal (11 citations)
  • Chlamydospermous seeds document the diversity and abundance of extinct gnetalean relatives in Early Cretaceous vegetation (6 citations)

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

  • Genus
  • Botany
  • Paleontology

His primary scientific interests are in Cretaceous, Botany, Ecology, Diversity and Paleontology. Botany is represented through his Stamen, Whorl, Tepal, Gynoecium and Pollen research. His Stamen study combines topics from a wide range of disciplines, such as Potomac Group, Ovule, Receptacle, Tricolpate and Ranunculales.

Kaj Raunsgaard Pedersen works in the field of Ecology, namely Abundance. His study of Diversity brings together topics like Magnoliales, Bennettitales, Welwitschia, Vegetation and Gnetum. His work carried out in the field of Paleontology brings together such families of science as Macrofossil and Molecular dating.
