Reference excerpt

Kari Korhonen (born July 24, 1943 in Sotkamo) is a Finnish mycologist and forest pathologist, known for his studies of fungi causing root rot. Korhonen graduated as a biologist from the University of Helsinki in 1968. He made his career as a researcher at the Finnish Forest Research Institute in Helsinki, beginning in 1973. From the start his research concentrated on the forest pathogen fungi then known as Heterobasidion annosum and Armillaria mellea. During his career over 40 years he collected more than 4000 isolates of these species in Scandinavia, Germany, Italy, Greece, USA, Canada, Estonia, Belarus, Siberia and China. Initially, following Veikko Hintikka's discovery of a technique to distinguish between Armillaria species by growing them together as single spore isolates on petri dishes and observing changes in the morphology of the cultures, Korhonen showed in 1978 that the European Armillaria mellea species complex could be separated into five reproductively isolated species. Similarly he studied the sexual incompatibility of bipolar systems also in Heterobasidion. As result of these studies the genus Heterobasidion was divided into three species while Armillaria has by now been divided into more than 40 species. Korhonen has published more than 50 scientific papers in international journals and edited books, almost all dealing with root rot fungi and their antagonists. For his pioneering work, he received an honorary doctorate from the University of Monaco of Bavaria in 1992. Fungal species named in honor of Korhonen include Entoloma korhonenii (Noordeloos 2004) and Hygrophorus korhonenii (Harmaja 1985).

Worked examples

Example 1 — a first encounter with Kari Korhonen (biologist)

Start with the simplest possible case. Write down what Kari Korhonen (biologist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kari Korhonen (biologist) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kari Korhonen (biologist) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kari Korhonen (biologist)

In research: Kari Korhonen (biologist) appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Kari Korhonen (biologist) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Kari Korhonen (biologist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1943 births, Finnish foresters, Finnish mycologists, so understanding it makes those chapters shorter.
In everyday life: Look for Kari Korhonen (biologist) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
