Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Botany
  • Ecosystem

Botany, Ecology, Root system, Glomus and Mycorrhiza are his primary areas of study. His Botany research focuses on Hypha in particular. His work in Ecology addresses subjects such as Rhizosphere, which are connected to disciplines such as Mutualism.

His biological study spans a wide range of topics, including Biological system, Toxicology, Mycorrhizal fungi and Field conditions. The Glomus study combines topics in areas such as Arbuscular mycorrhiza and Shoot. The subject of his Mycorrhiza research is within the realm of Symbiosis.

His most cited work include:

  • The Varying Success of Invaders (1100 citations)
  • Rapid Changes in Flowering Time in British Plants (1043 citations)
  • Biodiversity and ecosystem services: a multilayered relationship (951 citations)

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

Alastair Fitter mainly focuses on Botany, Ecology, Mycorrhiza, Agronomy and Symbiosis. His Botany study frequently draws parallels with other fields, such as Arbuscular mycorrhiza. As part of his studies on Ecology, Alastair Fitter often connects relevant subjects like Glomeromycota.

He interconnects Fungicide, Benomyl, Colonization, Carbon dioxide and Mycelium in the investigation of issues within Mycorrhiza. His study brings together the fields of Nutrient and Agronomy. His Symbiosis research incorporates themes from Holcus lanatus and Mycorrhizal fungi.

He most often published in these fields:

  • Botany (50.72%)
  • Ecology (31.88%)
  • Mycorrhiza (25.12%)

What were the highlights of his more recent work (between 2003-2015)?

  • Botany (50.72%)
  • Ecology (31.88%)
  • Mycorrhiza (25.12%)

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

His primary areas of investigation include Botany, Ecology, Mycorrhiza, Symbiosis and Glomeromycota. His research in Botany tackles topics such as Arbuscular mycorrhiza which are related to areas like Root system architecture. The Ecosystem, Community, Community structure and Environmental change research he does as part of his general Ecology study is frequently linked to other disciplines of science, such as Natural selection, therefore creating a link between diverse domains of science.

His research investigates the link between Symbiosis and topics such as Plantago that cross with problems in Shoot and Microcosm. His work carried out in the field of Respiration brings together such families of science as Acclimatization, Nutrient and Agronomy. Many of his research projects under Agronomy are closely connected to Shading with Shading, tying the diverse disciplines of science together.

Between 2003 and 2015, his most popular works were:

  • Biodiversity and ecosystem services: a multilayered relationship (951 citations)
  • Relative roles of niche and neutral processes in structuring a soil microbial community (536 citations)
  • AN ARCHITECTURAL APPROACH TO THE COMPARATIVE ECOLOGY OF PLANT ROOT SYSTEMS (410 citations)

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

  • Ecology
  • Botany
  • Ecosystem

His scientific interests lie mostly in Ecology, Ecosystem, Botany, Glomeromycota and Biodiversity. His work on Soil biology and Soil ecology as part of general Ecology research is frequently linked to Natural selection, bridging the gap between disciplines. His Ecosystem research includes elements of Ordination, Glomeraceae and Environmental resource management.

His work focuses on many connections between Botany and other disciplines, such as Symbiosis, that overlap with his field of interest in Microorganism. Alastair Fitter usually deals with Glomeromycota and limits it to topics linked to Mycelium and Evolutionary ecology, Mycorrhiza, Fungus and Organic matter. His Biodiversity research incorporates elements of Soil biodiversity, Ecosystem management and Ecosystem health, Ecosystem services.
