Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Fungus
  • Ecology

His scientific interests lie mostly in Botany, Trichoderma, Hypocrea, Taxonomy and Hypocreales. His Botany study incorporates themes from Hypocreaceae and Monophyly. His study in Trichoderma is interdisciplinary in nature, drawing from both Internal transcribed spacer, Fungi imperfecti, Microbiology, Biological pest control and Conidium.

His Hypocrea research incorporates elements of Trichoderma harzianum and Phylogenetics, Ribosomal DNA. His research investigates the link between Taxonomy and topics such as Clade that cross with problems in Trichothecene. His Nectria research is multidisciplinary, incorporating elements of Bionectriaceae, Gliocladium, Nectriaceae and Neonectria.

His most cited work include:

  • Taxonomy and phylogeny of Gliocladium analysed from nuclear large subunit ribosomal DNA sequences (552 citations)
  • Genera of Bionectriaceae, Hypocreaceae and Nectriaceae (Hypocreales, Ascomycetes) (289 citations)
  • Trichoderma: a review of biology and systematics of the genus (278 citations)

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

Gary J. Samuels focuses on Botany, Trichoderma, Hypocrea, Taxonomy and Hypocreales. His Botany research integrates issues from Clade, Phylogenetic tree and Hypocreaceae. The various areas that Gary J. Samuels examines in his Phylogenetic tree study include Phylogenetics and DNA sequencing.

His studies examine the connections between Trichoderma and genetics, as well as such issues in Theobroma, with regards to Endophyte. His research investigates the connection between Hypocrea and topics such as Ribosomal DNA that intersect with issues in Sequence analysis. His Taxonomy research incorporates themes from Hypomyces and Species complex.

He most often published in these fields:

  • Botany (81.12%)
  • Trichoderma (35.66%)
  • Hypocrea (32.87%)

What were the highlights of his more recent work (between 2008-2017)?

  • Botany (81.12%)
  • Trichoderma (35.66%)
  • Hypocrea (32.87%)

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

Gary J. Samuels mostly deals with Botany, Trichoderma, Hypocrea, Taxonomy and Hypocreales. Gary J. Samuels combines subjects such as Phylogenetics, Clade, Species complex, Phylogenetic tree and Hypocreaceae with his study of Botany. His studies deal with areas such as Trichoderma harzianum, Theobroma, Hemicellulose, Forestry and Mycelium as well as Trichoderma.

His Hypocrea research includes themes of Ecology, Beta-glucosidase, Nomenclature, Xylan and Xylanase. The study incorporates disciplines such as Nectriaceae, Nectria and Ascomycota in addition to Taxonomy. Gary J. Samuels has researched Hypocreales in several fields, including Lophira alata, Moniliophthora, Conidium and Ochnaceae.

Between 2008 and 2017, his most popular works were:

  • Colletotrichum gloeosporioides s.l. associated with Theobroma cacao and other plants in Panama: multilocus phylogenies distinguish host-associated pathogens from asymptomatic endophytes. (165 citations)
  • Delimitation of Neonectria and Cylindrocarpon (Nectriaceae, Hypocreales, Ascomycota) and related genera with Cylindrocarpon-like anamorphs (134 citations)
  • Systematics of the Trichoderma harzianum species complex and the re-identification of commercial biocontrol strains (119 citations)

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

  • Botany
  • Fungus
  • Ecology

Gary J. Samuels spends much of his time researching Botany, Trichoderma, Hypocrea, Taxonomy and Hypocreales. His Botany research is multidisciplinary, incorporating perspectives in Nectriaceae and Clade. His Trichoderma study combines topics in areas such as Nomenclature and Nomenclature Committee.

He interconnects Monophyly, Species complex, Cylindrocarpon and Molecular phylogenetics in the investigation of issues within Taxonomy. His research in Hypocreales is mostly focused on Hypocreaceae. His work deals with themes such as Type, Bionectriaceae and Sordariomycetes, which intersect with Hypocreaceae.
