Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Paleontology
  • Genus

His primary areas of study are Ecology, Paleontology, Fossil Record, Taxon and Extinction. His Ecology study frequently draws connections to other fields, such as Pleistocene. James W. Valentine focuses mostly in the field of Paleontology, narrowing it down to topics relating to Biota and, in certain cases, Adaptive strategies, Plate tectonics, Fauna and Paleoecology.

He combines subjects such as Evolutionary biology, Cambrian explosion, Phanerozoic and Molecular clock with his study of Fossil Record. In his study, Genus and Ordovician radiation is strongly linked to Paleobiology Database, which falls under the umbrella field of Taxon. His studies examine the connections between Extinction and genetics, as well as such issues in Macroevolution, with regards to Biogeography, Extinction event, Tropical climate and Macroecology.

His most cited work include:

  • Out of the Tropics: Evolutionary Dynamics of the Latitudinal Diversity Gradient (590 citations)
  • Marine latitudinal diversity gradients: Tests of causal hypotheses (391 citations)
  • Phanerozoic marine diversity and the fossil record (335 citations)

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

Ecology, Paleontology, Evolutionary biology, Taxon and Extinction are his primary areas of study. His study in Biodiversity, Species richness, Species diversity, Range and Biogeography falls under the purview of Ecology. James W. Valentine focuses mostly in the field of Biodiversity, narrowing it down to matters related to Tropics and, in some cases, Ecosystem.

His studies deal with areas such as Paleobiology Database, Phanerozoic and Biota as well as Paleontology. His Evolutionary biology research also works with subjects such as

  • Phylum and related Zoology and Morphology,
  • Fossil Record which connect with Body plan. His work on Extinction event is typically connected to Origination and Diversification as part of general Extinction study, connecting several disciplines of science.

He most often published in these fields:

  • Ecology (47.62%)
  • Paleontology (26.53%)
  • Evolutionary biology (17.01%)

What were the highlights of his more recent work (between 2005-2018)?

  • Ecology (47.62%)
  • Biodiversity (12.24%)
  • Species richness (9.52%)

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

James W. Valentine mostly deals with Ecology, Biodiversity, Species richness, Extinction and Biogeography. Ecology is frequently linked to Macroevolution in his study. His Biodiversity study combines topics from a wide range of disciplines, such as Paleontology, Tropics and Species diversity.

The study incorporates disciplines such as Dominance and Extinction event in addition to Paleontology. His work in Biogeography covers topics such as Fauna which are related to areas like Oceanography, Benthic zone, Global change and Marine biology. His Taxon research is multidisciplinary, incorporating perspectives in Clade and Subgenus.

Between 2005 and 2018, his most popular works were:

  • Out of the Tropics: Evolutionary Dynamics of the Latitudinal Diversity Gradient (590 citations)
  • Out of the tropics, but how? Fossils, bridge species, and thermal ranges in the dynamics of the marine latitudinal diversity gradient (136 citations)
  • Climate Change and the Integrity of Science (122 citations)

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

  • Ecology
  • Paleontology
  • Genus

James W. Valentine spends much of his time researching Ecology, Biodiversity, Species richness, Macroevolution and Extinction. His Ecology research incorporates themes from Oceanography and Clade. As a member of one scientific family, James W. Valentine mostly works in the field of Biodiversity, focusing on Tropics and, on occasion, Continental shelf, Extratropical cyclone, Species diversity, Evolutionary dynamics and Paleoecology.

His work is dedicated to discovering how Species richness, Biological dispersal are connected with Range, Conservation biology, Ecology and Species distribution and other disciplines. His Extinction study frequently draws connections to adjacent fields such as Paleontology. James W. Valentine interconnects Tropical climate and Extinction event in the investigation of issues within Paleontology.
