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

Lowell P. Bush mainly focuses on Botany, Agronomy, Endophyte, Animal science and Ergovaline. His study in Botany is interdisciplinary in nature, drawing from both Epichloë, Nitrosamine and Nicotiana tabacum. While the research belongs to areas of Endophyte, Lowell P. Bush spends his time largely on the problem of Loline alkaloid, intersecting his research to questions surrounding Festuca and Epichloë coenophiala.

As a part of the same scientific study, he usually deals with the Animal science, concentrating on Acremonium coenophialum and frequently concerns with Litter. His work carried out in the field of Ergovaline brings together such families of science as Endocrinology and Lysergic acid. Lowell P. Bush has researched Alkaloid in several fields, including Biochemistry and Nicotine.

He most often published in these fields:

  • Botany (34.81%)
  • Agronomy (25.19%)
  • Endophyte (22.22%)

What were the highlights of his more recent work (between 2007-2019)?

  • Ergovaline (18.52%)
  • Botany (34.81%)
  • Endocrinology (10.37%)

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

His primary areas of study are Ergovaline, Botany, Endocrinology, Biochemistry and Animal science. His Ergovaline research includes elements of Vasoconstriction, Lysergic acid, Agronomy and Lolium. His Botany study frequently draws connections between related disciplines such as Epichloë.

His Biochemistry study combines topics in areas such as Nornicotine, Nicotine and Toxicity. His Animal science study combines topics from a wide range of disciplines, such as Fescue toxicosis, Rumen, Blood flow and Respiration rate. His Endophyte research is multidisciplinary, incorporating elements of Neotyphodium, Loline alkaloid, Host, Litter and Festuca arundinacea.

Between 2007 and 2019, his most popular works were:

  • Effects of multiple climate change factors on the tall fescue-fungal endophyte symbiosis: infection frequency and tissue chemistry (68 citations)
  • Hemodynamics are altered in the caudal artery of beef heifers fed different ergot alkaloid concentrations. (56 citations)
  • Alkaloids may not be responsible for endophyte‐associated reductions in tall fescue decomposition rates (55 citations)

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

  • Botany
  • Enzyme
  • Biochemistry

His scientific interests lie mostly in Ergovaline, Endocrinology, Lysergic acid, Endophyte and Ergocristine. His Ergovaline research is multidisciplinary, incorporating perspectives in Artery and Caudal artery. His studies deal with areas such as Hemodynamics and Anatomy as well as Endocrinology.

As part of the same scientific family, Lowell P. Bush usually focuses on Lysergic acid, concentrating on Vasoconstriction and intersecting with Myograph. His work deals with themes such as Lolium, Agronomy, Incubation and Loline alkaloid, which intersect with Endophyte. Festuca arundinacea is a subfield of Botany that Lowell P. Bush explores.
