Reference excerpt

Jan-Peter Frahm (14 February 1945 – 5 February 2014) was a German botanist dedicated to the study of mosses. The standard author abbreviation J.-P.Frahm is used to indicate this person as the author when citing a botanical name.

Career Frahm studied biology and geography at the University of Hamburg before switching to the University of Kiel for his undergraduate degree. He returned to Kiel and earned his Ph.D. in botany in 1972. He then worked at the University of Duisburg, where he was appointed professor in 1981. Between 1978 and 1994 he issued a number of exsiccatae, among them Bryophyta Vogesiaca exsiccata (1985–1988) and Campylopodes exsiccatae (1980–1992). Research stays at foreign institutes (eg. Helsinki, Paris, Stockholm, Chicago) and a visiting professorship at the University of Alberta in 1989 followed. He moved from Duisburg to the University of Bonn in 1994. He was honored in 1995 with the Richard Spruce Award by the International Association of Bryologists for excellence in bryology. He was also awarded by the University of Helsinki. In recognition of his achievements, new species such as Sphagnum frahmii, Porotrichum frahmii, Cololejeunea frahmii, Pylaisiella frahmii and Porothamnium frahmii were named after him. The genus Frahmiella in the family Brachytheciaceae also bears his name. In 2014, he became the namesake of the bryological online journal Frahmia. Frahm conducted research on numerous topics of bryology and published more than 650 publications. Within his moss research, he was concerned with bioindication. Frahm noted that the improved air quality in cities has led to an increased number of lichen species colonizing urban areas. He also demonstrated that the release of ammonia by auto-catalysts causes nitrogen-loving lichens and mosses and nitrogen-emitting plants to settle along roads. Frahm was also passionate about cooking. He published his own cook book, 10000 Kochideen, in 2007.

Journalistic activity Frahm was the publisher of the following journals:

Archive For Bryology, an internet magazine Bryologische Rundbriefe, an electronic newsletter with information on moss research in Germany Limprichtia, a magazine for moss research in Germany Tropical Bryology, an international non-profit journal on the biology of tropical mosses; now under the title Bryophyte Diversity and Evolution

Worked examples

Example 1 — a first encounter with Jan-Peter Frahm

Start with the simplest possible case. Write down what Jan-Peter Frahm claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Jan-Peter Frahm 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 Jan-Peter Frahm 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 Jan-Peter Frahm

In research: Jan-Peter Frahm appears in astronomy 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 Jan-Peter Frahm 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: Jan-Peter Frahm is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1945 births, 2014 deaths, 20th-century German botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Jan-Peter Frahm 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.
