Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Gene
  • Ecology

Andrew G. Stephenson mainly focuses on Botany, Pollen, Agronomy, Pollinator and Cucurbita pepo. His study looks at the intersection of Botany and topics like Horticulture with Natural selection. His Pollen study combines topics in areas such as Campanulaceae and Competition.

His research integrates issues of Fructification, Ripening, Squash and Multiple fruit in his study of Agronomy. In his study, Natural population growth, Pollen source and Cucurbita foetidissima is inextricably linked to Anthesis, which falls within the broad field of Pollinator. His studies examine the connections between Cucurbita pepo and genetics, as well as such issues in Cucurbitaceae, with regards to Cultivar.

His most cited work include:

  • Flower and Fruit Abortion: Proximate Causes and Ultimate Functions (1560 citations)
  • CHAPTER 6 – Male Competition, Female Choice, and Sexual Selection in Plants (384 citations)
  • Fruit Set, Herbivory, Fruit Reduction, and the Fruiting Strategy of Catalpa Speciosa (Bignoniaceae) (238 citations)

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

His main research concerns Botany, Pollen, Cucurbita pepo, Inbreeding depression and Inbreeding. His study in Horticulture extends to Botany with its themes. His Pollen research is multidisciplinary, relying on both Competition and Germination.

His Cucurbita pepo research includes elements of Agronomy, Cucurbita, Zucchini yellow mosaic virus, Cucurbitaceae and Erwinia. His studies examine the connections between Inbreeding depression and genetics, as well as such issues in Selfing, with regards to Outcrossing. Andrew G. Stephenson has researched Pollen tube in several fields, including Sporophyte, Ovary and Gynoecium.

He most often published in these fields:

  • Botany (68.70%)
  • Pollen (45.04%)
  • Cucurbita pepo (29.77%)

What were the highlights of his more recent work (between 2011-2021)?

  • Botany (68.70%)
  • Herbivore (19.08%)
  • Solanum (13.74%)

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

His primary areas of study are Botany, Herbivore, Solanum, Cucurbita pepo and Inbreeding. His works in Trichome and Pollen are all subjects of inquiry into Botany. His work in the fields of Pollen, such as Pollination, intersects with other areas such as Safer sex.

The various areas that he examines in his Herbivore study include Insect and Inbreeding depression. His Cucurbita pepo research is included under the broader classification of Horticulture. His work carried out in the field of Inbreeding brings together such families of science as Jasmonic acid and Larva.

Between 2011 and 2021, his most popular works were:

  • Pathogen effects on vegetative and floral odours mediate vector attraction and host exposure in a complex pathosystem. (72 citations)
  • Inbreeding alters volatile signalling phenotypes and influences tri-trophic interactions in horsenettle (Solanum carolinense L.) (71 citations)
  • Constitutive and herbivore‐induced structural defenses are compromised by inbreeding in Solanum carolinense (Solanaceae) (43 citations)

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

  • Botany
  • Gene
  • Ecology

Andrew G. Stephenson focuses on Botany, Solanum, Zucchini yellow mosaic virus, Herbivore and Plant defense against herbivory. While the research belongs to areas of Botany, Andrew G. Stephenson spends his time largely on the problem of Ecology, intersecting his research to questions surrounding Cucurbita. His Solanum study incorporates themes from Insect, Caterpillar and Trichome.

As a member of one scientific family, Andrew G. Stephenson mostly works in the field of Insect, focusing on Predation and, on occasion, Trophic level. His Zucchini yellow mosaic virus research focuses on Cucurbita pepo and how it connects with Pathogen and Wilt disease. The Herbivore study combines topics in areas such as Inbreeding and Weed.
