José Castulo Zeledón

José Castulo Zeledón 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 José Castulo Zeledón rather than just read about it. In short: José Castulo Zeledón (March 24, 1846 – July 16, 1923) was a Costa Rican ornithologist. He was the son of Don Manuel Zeledón, governor of the district of San José.

Key takeaways

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

Reference excerpt

José Castulo Zeledón (March 24, 1846 – July 16, 1923) was a Costa Rican ornithologist. He was the son of Don Manuel Zeledón, governor of the district of San José. José became interested in birds at an early age, and learned about ornithology from the German naturalist and physician Alexander von Frantzius, when he was employed at his pharmacy in San José. Zeledón started collecting birds locally, the specimens being sent to Jean Cabanis at the Berlin Museum. In 1868 Frantzius returned to Germany. En route, he took Zeledón to Washington, where Zeledón met Spencer Fullerton Baird and became an assistant at the Smithsonian Institution. It was here that he began a lifelong friendship with Robert Ridgway. In 1872 Zeledón returned to Costa Rica as zoologist on an expedition led by William More Gabb. During this expedition Zeledón made the first collection of birds in Talamanca. Zeledón took over the pharmacy set up by Frantzius, and this eventually made him a wealthy man. He continued to collect birds when time allowed, donating his collection to the Costa Rican National Museum when it was founded, mainly due to his own efforts. This collection was Zeledón's main contribution to ornithology, as it contained many new species, although these were often described by others. He was also able to assist other ornithologists who visited Costa Rica during his lifetime. Zeledón is commemorated in the scientific names of a number of birds, including the wrenthrush, Zeledonia coronata and the white-fronted tyrannulet, Phyllomyias zeledoni. Also, a species of snake, Geophis zeledoni, is named in his honor. He was married to Amparo de Zeledón.

Worked examples

Example 1 — a first encounter with José Castulo Zeledón

Start with the simplest possible case. Write down what José Castulo Zeledón 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 José Castulo Zeledón 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 José Castulo Zeledón 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 José Castulo Zeledón

In research
José Castulo Zeledón 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 José Castulo Zeledón 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
José Castulo Zeledón is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1846 births, 1923 deaths, Costa Rican biologists, so understanding it makes those chapters shorter.
In everyday life
Look for José Castulo Zeledón 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.
