Reference excerpt

John Douglas Lynch (born July 30, 1942) is an American herpetologist. His research focuses on the neotropical herpetofauna.

Biography In 1964, Lynch conducted research in Mexico as part of his master's degree at the University of Illinois, studying the frog genus Eleutherodactylus. After receiving his Master of Science, he enrolled at the University of Kansas, where he studied zoology under William Edward Duellman. In 1967, he went on his first expedition to Ecuador, where he collected frogs of the genus Eleutherodactylus and members of the family Centrolenidae (glass frogs). He earned his Ph.D. in 1969 with the dissertation Evolutionary relationships and osteology of the frog family Leptodactylidae. During an expedition in 1980 with María Cristina Ardila Robayo and Pedro Ruiz in the highlands of the Colombian departments of Cauca and Huila, he discovered more than 20 new frog species. From 1969 to 1997, Lynch was a professor at the University of Nebraska–Lincoln. In 1997, he became an associate professor and curator of herpetology at the Instituto de Ciencias Naturales of the Universidad Nacional de Colombia. Since 1999, he has lived in Colombia. In the summer of 2000, he was among a group of scientists briefly kidnapped by the Colombian guerrilla organization ELN. Lynch has participated in the scientific descriptions of more than 200 frog species, including many taxa in the genera Eleutherodactylus, Pristimantis and Strabomantis. Lynch has a son and a daughter.

Eponyms Several taxa have been named in honor of John Douglas Lynch, including Atelopus lynchi, Rhaebo lynchi, Centrolene lynchi, Colostethus lynchi, Hyloscirtus lynchi, Noblella lynchi, and Pristimantis lynchi, as well as the genera Lynchophrys and Lynchius. The specific epithet of the salamander Pseudoeurycea lynchi refers to the zoologist James Francis Lynch.

Worked examples

Example 1 — a first encounter with John Douglas Lynch

Start with the simplest possible case. Write down what John Douglas Lynch 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 John Douglas Lynch 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 John Douglas Lynch 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 John Douglas Lynch

In research: John Douglas Lynch 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 John Douglas Lynch 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: John Douglas Lynch is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1942 births, 20th-century American zoologists, Academic staff of the National University of Colombia, so understanding it makes those chapters shorter.
In everyday life: Look for John Douglas Lynch 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.
