Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Predation
  • Habitat

Kai Norrdahl spends much of his time researching Ecology, Predation, Microtus, Vole and Population cycle. Ecology is closely attributed to Population density in his research. Kai Norrdahl has researched Microtus in several fields, including Range, Seasonal breeder, Least weasel and Field vole.

His work carried out in the field of Field vole brings together such families of science as Weasel, Aegolius, Overwintering, Density dependence and Bank vole. His Population cycle research is multidisciplinary, incorporating perspectives in Mortality factors and Rodent populations. His studies deal with areas such as Mammal and Generalist and specialist species as well as Predator.

His most cited work include:

  • Numerical and Functional Responses of Kestrels, Short‐Eared Owls, and Long‐Eared Owls to Vole Densities (346 citations)
  • Responses of stoats and least weasels to fluctuating food abundances: is the low phase of the vole cycle due to mustelid predation? (239 citations)
  • Experimental reduction of predators reverses the crash phase of small-rodent cycles (229 citations)

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

His primary scientific interests are in Ecology, Predation, Vole, Microtus and Predator. His study ties his expertise on Zoology together with the subject of Ecology. His research in Predation intersects with topics in Nest, Population density, Sorex and Seasonality.

His work in Vole tackles topics such as Bank vole which are related to areas like Aegolius. Kai Norrdahl works mostly in the field of Microtus, limiting it down to concerns involving Herbivore and, occasionally, Forage. His studies in Predator integrate themes in fields like Falconidae and Abundance.

He most often published in these fields:

  • Ecology (91.67%)
  • Predation (62.50%)
  • Vole (58.33%)

What were the highlights of his more recent work (between 2011-2020)?

  • Ecology (91.67%)
  • Shrub (5.56%)
  • Species richness (5.56%)

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

Kai Norrdahl focuses on Ecology, Shrub, Species richness, Habitat and Herbaceous plant. His research on Ecology frequently links to adjacent areas such as Biological dispersal. The concepts of his Habitat study are interwoven with issues in Nocturnal, Falco tinnunculus and Intraguild predation, Predator.

His Herbivore research integrates issues from Monoculture and Vole. His work deals with themes such as Microtus, Tree species and Alder, Alnus glutinosa, which intersect with Vole. His work on Optimal foraging theory as part of general Predation study is frequently linked to Chironomidae, bridging the gap between disciplines.

Between 2011 and 2020, his most popular works were:

  • What you need is what you eat? Prey selection by the bat Myotis daubentonii (65 citations)
  • Sediment organic tin contamination promotes impoverishment of non-biting midge species communities in the Archipelago Sea, S-W Finland (12 citations)
  • Population Genetics of Daubenton's Bat (Myotis daubentonii) in the Archipelago Sea, SW Finland (10 citations)

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

  • Ecology
  • Habitat
  • Predation

His primary areas of study are Ecology, Biological dispersal, Isolation by distance, Population genetics and Archipelago. Ecology is represented through his Plant ecology, Benthic zone and Optimal foraging theory research. The various areas that Kai Norrdahl examines in his Plant ecology study include Biomass, Woody plant, Herbaceous plant, Species richness and Introduced species.

In his research, Detritus is intimately related to Food web, which falls under the overarching field of Benthic zone. Kai Norrdahl is investigating Optimal foraging theory as part of his inquiry into Foraging and Predation. His Population ecology research incorporates themes from Biodiversity and Insectivore.
