Overview

What is he best known for?

The fields of study he is best known for:

Botany
Ecology
Genus

His main research concerns Botany, Ophiostomatales, Ambrosia fungi, Ophiostoma and Internal transcribed spacer. As part of his studies on Botany, he often connects relevant areas like Phylogenetics. The various areas that he examines in his Ophiostoma study include Sensu and Taxonomy.

The Internal transcribed spacer study combines topics in areas such as Theobroma, Host and Clade. His work deals with themes such as Ambrosiella, Xyleborini, Mycangium and Wilt disease, which intersect with Xyleborus glabratus. His Grosmannia study integrates concerns from other disciplines, such as Grosmannia clavigera, Dendroctonus, Phloem, Hylastes ater and Bark.

His most cited work include:

INTERACTIONS AMONG SCOLYTID BARK BEETLES, THEIR ASSOCIATED FUNGI, AND LIVE HOST CONIFERS (623 citations)
A Fungal Symbiont of the Redbay Ambrosia Beetle Causes a Lethal Wilt in Redbay and Other Lauraceae in the Southeastern United States (287 citations)
A PCR-based identification method for species of Armillaria (177 citations)

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

Thomas C. Harrington mostly deals with Botany, Ceratocystis, Ceratocystis fimbriata, Internal transcribed spacer and Phylogenetic tree. His study in Ribosomal DNA extends to Botany with its themes. His Ceratocystis study incorporates themes from Bark beetle and Genetics.

His Ceratocystis fimbriata research is multidisciplinary, incorporating perspectives in Clade, Colocasia esculenta, Eucalyptus, Ipomoea and Genetic variation. His work in Phylogenetic tree tackles topics such as Phylogenetics which are related to areas like Evolutionary biology, Taxon and Ribosomal RNA. His work is dedicated to discovering how Ambrosia beetle, Microascales are connected with Zoology and Genus and other disciplines.

He most often published in these fields:

Botany (71.23%)
Ceratocystis (20.55%)
Ceratocystis fimbriata (19.18%)

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

Botany (71.23%)
Ceratocystis (20.55%)
Ceratocystis fimbriata (19.18%)

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

Thomas C. Harrington focuses on Botany, Ceratocystis, Ceratocystis fimbriata, Phylogenetic tree and Zoology. His Botany research is multidisciplinary, relying on both Host and Genetic diversity. His biological study spans a wide range of topics, including Crown, Phylogenetics, Metrosideros polymorpha and Horticulture.

Thomas C. Harrington usually deals with Ceratocystis fimbriata and limits it to topics linked to Colocasia esculenta and Biological dispersal, Monophyly, Population genetics, Mycelium and Mating. Thomas C. Harrington interconnects Endophyte and Quercus spp in the investigation of issues within Phylogenetic tree. In his research on the topic of Zoology, Ambrosia beetle and Ambrosia fungi is strongly related with Microascales.

Between 2016 and 2021, his most popular works were:

New Ceratocystis species associated with rapid death of Metrosideros polymorpha in Hawai`i (30 citations)
Genetic variation in native populations of the laurel wilt pathogen, Raffaelea lauricola , in Taiwan and Japan and the introduced population in the United States (19 citations)
Patterns of coevolution between ambrosia beetle mycangia and the Ceratocystidaceae, with five new fungal genera and seven new species. (12 citations)

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

Botany
Fungus
Genus

The scientist’s investigation covers issues in Ambrosia beetle, Zoology, Botany, Fungus and Microascales. His studies deal with areas such as Xanthosoma, Phylogenetic tree, Metrosideros polymorpha and Invasive species as well as Zoology. His biological study focuses on Wilt disease.

His Wilt disease research focuses on UPGMA and how it relates to Ceratocystis. His research integrates issues of Mutualism, Species level, Genus and Coevolution in his study of Fungus. Thomas C. Harrington has included themes like Taxonomy, Ribosomal DNA, DNA barcoding and Ambrosia fungi in his Microascales study.
