Othmar Reiser

Othmar Reiser 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 Othmar Reiser rather than just read about it. In short: Othmar Reiser or Otmar Rajzer (21 December 1861 – 31 March 1936, Pickern) was an Austro-Slovenian ornithologist and naturalist who worked as curator of the bird collections in the natural history museum at Sarajevo, working there from its foundation for thirty-three years during which he explored various regions including the Balkans and South America and collected specimens. Several species have been named after hi…

Key takeaways

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

Reference excerpt

Othmar Reiser or Otmar Rajzer (21 December 1861 – 31 March 1936, Pickern) was an Austro-Slovenian ornithologist and naturalist who worked as curator of the bird collections in the natural history museum at Sarajevo, working there from its foundation for thirty-three years during which he explored various regions including the Balkans and South America and collected specimens. Several species have been named after him.

Biography

Reiser was born in Vienna, son of a well known lawyer, Otmar Reiser sr. whose namesake father was a well-known mayor of Maribor. He studied at the local gymnasium, at Novo Mesto (matriculating in 1882) and then joined as a reserve lieutenant in the 47th Infantry Regiment. He then went to the College of Agriculture in Vienna (graduating in 1887). He was involved in founding the National Museum of Bosnia and Herzegovina in Sarajevo and then joined its department of Natural History and worked there until retirement in 1919. He worked at the ornithological observatory at Ljubljana and studied Balkan birds. He also studied the birds of Sarajevo and contributed specimens to the Maribor Museum. He received an honorary doctorate from the University of Graz in 1932. His collections of eggs and bird skins were donated to the museum in Sarajevo. Reiser exhibited his collections at the 1891 International Ornithological Congress in Budapest, at the Millenium Exhibition, Budapest and at the international hunting exhibition in Vienna (1910). He took part in expeditions to Montenegro, Bulgaria, Greece, Brazil, and Serbia. He also collected plants and was in charge of the herbarium after the death of the botanist Franz Fiala. In 1903 he took part in an expedition of the Austrian Academy of Sciences to north-east Brazil, during which he was the first to observe the Spix's macaw in the wild since its original discovery 84 years earlier.

Worked examples

Example 1 — a first encounter with Othmar Reiser

Start with the simplest possible case. Write down what Othmar Reiser 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 Othmar Reiser 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 Othmar Reiser 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 Othmar Reiser

In research
Othmar Reiser 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 Othmar Reiser 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
Othmar Reiser is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1861 births, 1936 deaths, Austrian biologist stubs, so understanding it makes those chapters shorter.
In everyday life
Look for Othmar Reiser 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.
