Gustaf von Paykull

Gustaf von Paykull is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Gustaf von Paykull rather than just read about it. In short: Gustav von Paykull (23 July 1757 – 28 January 1826) was a Swedish friherre (circa baron) and Marshal of the Court, ornithologist, and entomologist. He was a member of the Royal Swedish Academy from 1791 and a founder of the natural history museum (Naturhistoriska Riksmuseet) in Stockholm, through his 1819 donation of his extensive zoological collections to the academy (now in the Swedish Museum of Natural History).

Key takeaways

Gustaf von Paykull belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Gustaf von Paykull to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Gustaf von Paykull from memory before moving on to harder problems.

Reference excerpt

Gustav von Paykull (23 July 1757 – 28 January 1826) was a Swedish friherre (circa baron) and Marshal of the Court, ornithologist, and entomologist. He was a member of the Royal Swedish Academy from 1791 and a founder of the natural history museum (Naturhistoriska Riksmuseet) in Stockholm, through his 1819 donation of his extensive zoological collections to the academy (now in the Swedish Museum of Natural History). He was elected a member of the American Philosophical Society in 1801 and a Foreign Honorary Member of the American Academy of Arts and Sciences in 1804.

Publications His best-known publications are:

Monographia Histeroidum. Upsaliae : Palmblad iv 114 pp. (1811). Fauna Suecica. Insecta, Coleoptera. Upsala : Edman 3 volumes. (3 volumes, 1798, 1799, 1800)

Species named in his honor The red false black widow spider, Steatoda paykulliana The pantropical jumping spider, Plexippus paykulli The band-bellied crake, Porzana paykullii Scolopax paykullii, probably the red breasted snipe, or short-billed dowitcher, now known as Scolopax grisea Tortrix paykulliana – synonym of Epinotia ramella Alucita paykullella – synonym of Micropterix paykullella Amarygmus paykulii – Tenebrionine beetle Colymbetes paykulli – Dytiscid beetle

Worked examples

Example 1 — a first encounter with Gustaf von Paykull

Start with the simplest possible case. Write down what Gustaf von Paykull 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 Gustaf von Paykull 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 Gustaf von Paykull 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 Gustaf von Paykull

In research: Gustaf von Paykull 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 Gustaf von Paykull 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: Gustaf von Paykull is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1757 births, 1826 deaths, 18th-century Swedish zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Gustaf von Paykull 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.
