Overview

What is she best known for?

The fields of study she is best known for:

  • Ecology
  • Botany
  • Ecosystem

Her scientific interests lie mostly in Ecology, Endophyte, Botany, Mutualism and Herbivore. Kari Saikkonen has researched Ecology in several fields, including Symbiosis, Epichloë and Fungus. Her studies deal with areas such as Agrostis capillaris, Elymus repens and Festuca arundinacea as well as Endophyte.

Her biological study spans a wide range of topics, including Nutrient and Agronomy. Her research investigates the connection between Mutualism and topics such as Abiotic component that intersect with problems in Reactive oxygen species and Evolutionary ecology. Her Herbivore study integrates concerns from other disciplines, such as Competition and Ectomycorrhizae.

Her most cited work include:

  • FUNGAL ENDOPHYTES: A Continuum of Interactions with Host Plants (806 citations)
  • Evolution of endophyte-plant symbioses (409 citations)
  • Model systems in ecology: dissecting the endophyte–grass literature (237 citations)

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

Kari Saikkonen mainly investigates Botany, Endophyte, Ecology, Agronomy and Herbivore. Her study in the field of Plant use of endophytic fungi in defense, Festuca rubra and Betula pubescens is also linked to topics like Plant defense against herbivory. The study incorporates disciplines such as Mutualism, Symbiosis, Epichloë, Neotyphodium and Festuca pratensis in addition to Endophyte.

Her work deals with themes such as Festuca, Shoot, Litter, Festuca arundinacea and Abiotic component, which intersect with Epichloë. Ecology and PEST analysis are commonly linked in her work. Her Herbivore research is multidisciplinary, incorporating perspectives in Poaceae, Grazing and Predation.

She most often published in these fields:

  • Botany (46.51%)
  • Endophyte (45.74%)
  • Ecology (33.33%)

What were the highlights of her more recent work (between 2017-2021)?

  • Glyphosate (11.63%)
  • Epichloë (18.60%)
  • Ecology (33.33%)

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

Her primary scientific interests are in Glyphosate, Epichloë, Ecology, Festuca rubra and Botany. The Epichloë study combines topics in areas such as Endophyte, Host and Abiotic component. Her research is interdisciplinary, bridging the disciplines of Mutualism and Endophyte.

Her primary area of study in Ecology is in the field of Range. Her Festuca rubra research integrates issues from Zoology, Phenotypic plasticity, Herbivore and Genetic variation. Her Botany research is multidisciplinary, relying on both Integrated pest management and Metabolic pathway.

Between 2017 and 2021, her most popular works were:

  • Glyphosate decreases mycorrhizal colonization and affects plant-soil feedback. (28 citations)
  • Effects of a glyphosate-based herbicide on soil animal trophic groups and associated ecosystem functioning in a northern agricultural field (14 citations)
  • The recent northward expansion of Lymantria monacha in relation to realised changes in temperatures of different seasons (14 citations)

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

  • Ecology
  • Botany
  • Ecosystem

Her scientific interests lie mostly in Glyphosate, Ecosystem, Agronomy, Crop and Weed. Her study in Glyphosate is interdisciplinary in nature, drawing from both Livestock, Leptinotarsa and Plumage. Kari Saikkonen interconnects Microbiome, Biodiversity, Ecology and Environmental resource management in the investigation of issues within Ecosystem.

Her Agronomy study combines topics from a wide range of disciplines, such as Soil biology, Soil water, Decomposer, Plant litter and Arbuscular mycorrhiza. Her Crop research incorporates themes from Instar, Colorado potato beetle, Larva and Horticulture. Her studies in Weed integrate themes in fields like Endophyte, Perennial plant, No-till farming and Festuca pratensis.
