1943 - Fellow of the American Association for the Advancement of Science (AAAS)

Overview

What is he best known for?

The fields of study he is best known for:

  • Paleontology
  • Ecology
  • Genus

The scientist’s investigation covers issues in Paleontology, Ordovician, Paleozoic, Fauna and Ecology. Diachronous, Baltica, Biostratigraphy, Period and Biozone are among the areas of Paleontology where the researcher is concentrating his efforts. His Ordovician research is multidisciplinary, incorporating elements of Biodiversity, Phanerozoic, Sea level, Benthic zone and Extinction event.

The Biodiversity study combines topics in areas such as Reef and Katian. He works mostly in the field of Paleozoic, limiting it down to topics relating to Biogeography and, in certain cases, Proterozoic, Series and Palaeogeography, as a part of the same area of interest. His work in the fields of Pentamerida overlaps with other areas such as South china.

His most cited work include:

  • PAST: PALEONTOLOGICAL STATISTICAL SOFTWARE PACKAGE FOR EDUCATION AND DATA ANALYSIS (16811 citations)
  • Paleontological Data Analysis (801 citations)
  • Ordovician and Silurian sea–water chemistry, sea level, and climate: A synopsis (222 citations)

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

Paleontology, Ordovician, Fauna, Paleozoic and Ecology are his primary areas of study. David A. T. Harper has researched Paleontology in several fields, including Biodiversity, Benthic zone and Extinction event. His Extinction event research incorporates themes from Phanerozoic and Sea level.

His Ordovician research includes themes of Range and Terrane. His research integrates issues of Gondwana and Group in his study of Fauna. David A. T. Harper combines subjects such as Biostratigraphy and Palaeogeography with his study of Paleozoic.

He most often published in these fields:

  • Paleontology (87.04%)
  • Ordovician (60.56%)
  • Fauna (26.20%)

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

  • Paleontology (87.04%)
  • Ordovician (60.56%)
  • Fauna (26.20%)

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

His scientific interests lie mostly in Paleontology, Ordovician, Fauna, Biodiversity and Extinction event. His Paleontology study typically links adjacent topics like Benthic zone. His Ordovician study combines topics from a wide range of disciplines, such as Structural basin, Gondwana and Terrane.

His Fauna research incorporates elements of Range and China. His biological study spans a wide range of topics, including Period, Diachronous, Plankton, Spatial ecology and Devonian. His Extinction event research includes elements of Ecology and Glacial period.

Between 2013 and 2021, his most popular works were:

  • End Ordovician extinctions: A coincidence of causes (132 citations)
  • Onset of main Phanerozoic marine radiation sparked by emerging Mid Ordovician icehouse (86 citations)
  • A suspension-feeding anomalocarid from the Early Cambrian (81 citations)

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

  • Paleontology
  • Ecology
  • Genus

David A. T. Harper mostly deals with Paleontology, Ordovician, Biodiversity, Extinction event and Ecology. His work on Paleontology is being expanded to include thematically relevant topics such as Oyster. The concepts of his Ordovician study are interwoven with issues in Biozone, Paleozoic, Taxon, Sea level and Gondwana.

His research in Biodiversity intersects with topics in Period, Diachronous, Fauna, Katian and Benthic zone. David A. T. Harper interconnects Marine life and Facies in the investigation of issues within Fauna. His Extinction event study combines topics in areas such as Permian, Early Triassic, Mesozoic marine revolution and Ladinian.
