Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Botany
  • Genus

Ecology, Epirrita, Autumnal moth, Lepidoptera genitalia and Predation are his primary areas of study. Kai Ruohomäki has researched Epirrita in several fields, including Population density and Population cycle. As a part of the same scientific family, Kai Ruohomäki mostly works in the field of Population density, focusing on Operophtera and, on occasion, Resistance.

His Population cycle research integrates issues from Fecundity and Adult stage. His work investigates the relationship between Lepidoptera genitalia and topics such as PEST analysis that intersect with problems in Folivore and Phenology. As a member of one scientific family, Kai Ruohomäki mostly works in the field of Predation, focusing on Pupa and, on occasion, Delayed density dependence and Nymph.

His most cited work include:

  • Consequences of herbivory in the mountain birch (Betula pubescens ssp tortuosa): importance of the functional organization of the tree. (174 citations)
  • Causes of cyclicity of Epirrita autumnata (Lepidoptera, Geometridae): grandiose theory and tedious practice (165 citations)
  • Realized fecundity in Epirrita autumnata (Lepidoptera: Geometridae): relation to body size and consequences to population dynamics (150 citations)

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

Kai Ruohomäki focuses on Ecology, Epirrita, Autumnal moth, Lepidoptera genitalia and Betula pubescens. Sex ratio is closely connected to Zoology in his research, which is encompassed under the umbrella topic of Ecology. His research integrates issues of Fecundity, Population density, Pupa and Parasitism in his study of Epirrita.

Kai Ruohomäki works mostly in the field of Autumnal moth, limiting it down to topics relating to Population cycle and, in certain cases, Generalist and specialist species, as a part of the same area of interest. Kai Ruohomäki works mostly in the field of Lepidoptera genitalia, limiting it down to topics relating to PEST analysis and, in certain cases, Biological dispersal. His Betula pubescens study combines topics in areas such as Canopy, Herbivore, Shoot and Betulaceae.

He most often published in these fields:

  • Ecology (72.37%)
  • Epirrita (59.21%)
  • Autumnal moth (39.47%)

What were the highlights of his more recent work (between 2014-2018)?

  • Ecology (72.37%)
  • Zoology (22.37%)
  • Ixodes ricinus (5.26%)

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

His primary scientific interests are in Ecology, Zoology, Ixodes ricinus, Borrelia miyamotoi and Tick. His work on Epirrita, Phenotypic plasticity, Range and Pupa as part of general Ecology study is frequently connected to Geography, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. His work on Autumnal moth as part of his general Epirrita study is frequently connected to Insect outbreak, thereby bridging the divide between different branches of science.

Kai Ruohomäki has included themes like Betula pubescens, Hatching, Phenology and Local adaptation in his Phenotypic plasticity study. The study incorporates disciplines such as Ricinus and Babesia in addition to Tick. His Betula pendula study combines topics from a wide range of disciplines, such as Field experiment, Intraspecific competition, Gall, Genetic diversity and Herbivore.

Between 2014 and 2018, his most popular works were:

  • Crowdsourcing-based nationwide tick collection reveals the distribution of Ixodes ricinus and I. persulcatus and associated pathogens in Finland (42 citations)
  • Tick-borne bacterial pathogens in southwestern Finland (35 citations)
  • Additive and non-additive effects of birch genotypic diversity on arthropod herbivory in a long-term field experiment (30 citations)

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

  • Ecology
  • Genus
  • Botany

Kai Ruohomäki mainly focuses on Ixodes ricinus, Borrelia miyamotoi, Ixodes persulcatus, Ecology and Zoology. His Ixodes ricinus study incorporates themes from Tick-borne disease and Bartonella, Microbiology. His Borrelia miyamotoi study spans across into fields like Distribution, Crowdsourcing, Tick and Ixodes.

His Ecology research incorporates themes from Betula pendula and Genetic diversity.
