Everett M. Hansen

What is he best known for?

The fields of study he is best known for:

• Botany
• Ecology
• Fungus

His primary areas of investigation include Botany, Ecology, Phytophthora, Phytophthora ramorum and Taxonomy. Everett M. Hansen has researched Botany in several fields, including Microsatellite and Amplified fragment length polymorphism. Everett M. Hansen combines subjects such as Pathogen and Root rot with his study of Ecology.

His Phytophthora research incorporates elements of Taxon and Fagaceae. His Phytophthora ramorum research incorporates themes from Lithocarpus and Infestation. His Taxonomy study combines topics from a wide range of disciplines, such as Phylogeography and Phytophthora megasperma.

His most cited work include:

• Phytophthora ramorum: integrative research and management of an emerging pathogen in California and Oregon forests. (376 citations)
• Sudden Oak Death and Associated Diseases Caused by Phytophthora ramorum (147 citations)
• Multiple new phenotypic taxa from trees and riparian ecosystems in Phytophthora gonapodyides-P. megasperma ITS Clade 6, which tend to be high-temperature tolerant and either inbreeding or sterile. (139 citations)

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

His main research concerns Botany, Ecology, Phytophthora ramorum, Phytophthora and Sudden oak death. The study incorporates disciplines such as Inoculation and Internal transcribed spacer in addition to Botany. As part of the same scientific family, Everett M. Hansen usually focuses on Ecology, concentrating on Genetic diversity and intersecting with Population genetics.

Everett M. Hansen interconnects Host plants, Biological dispersal, Forestry and Lithocarpus in the investigation of issues within Phytophthora ramorum. Everett M. Hansen has included themes like Vaccinium ovatum and Rhododendron macrophyllum in his Lithocarpus study. His Phytophthora research also works with subjects such as

• Clade which is related to area like Taxonomy,
• Quercus agrifolia most often made with reference to Invasive species.

He most often published in these fields:

• Botany (43.56%)
• Ecology (36.81%)
• Phytophthora ramorum (36.20%)

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

• Ecology (36.81%)
• Phytophthora (30.06%)
• Botany (43.56%)

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

Everett M. Hansen focuses on Ecology, Phytophthora, Botany, Sudden oak death and Phytophthora ramorum. His work on Range and Host as part of general Ecology study is frequently connected to Pluvialis and Phytophthora pluvialis, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. The Phytophthora study combines topics in areas such as Forest ecology and Clade.

His Botany study integrates concerns from other disciplines, such as Inoculation and DNA sequencing. His studies deal with areas such as Pathogen and Forestry as well as Sudden oak death. His Phytophthora ramorum study which covers Biological dispersal that intersects with Outbreak, Infestation and Epidemiology.

Between 2013 and 2021, his most popular works were:

• Strategies of attack and defence in woody plant-Phytophthora interactions (66 citations)
• Compendium of Conifer Diseases (63 citations)
• Phytophthora Species Emerging as Pathogens of Forest Trees (44 citations)

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

• Botany
• Ecology
• Fungus

Everett M. Hansen spends much of his time researching Phytophthora, Botany, Ecology, Phytophthora ramorum and Woody plant. His research on Phytophthora focuses in particular on Phytophthora cinnamomi. The various areas that Everett M. Hansen examines in his Botany study include Common species and Species diversity.

In the subject of general Ecology, his work in Riparian zone is often linked to Aerial survey, Period and Rhizosphere, thereby combining diverse domains of study. His work in the fields of Sudden oak death overlaps with other areas such as Early introduction. His work carried out in the field of Woody plant brings together such families of science as Host plants, Stem bark and Compendium.
