Hynobius sonani

Hynobius sonani 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 Hynobius sonani rather than just read about it. In short: Hynobius sonani, the Taichū salamander, is a species of salamander in the family Hynobiidae, endemic to Taiwan, where it occurs in the Central Mountain Range above 2,750 m (9,020 ft). Its natural habitats are from open alpine habitats to shaded moist evergreen forests; it breeds in streams.

Key takeaways

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

Reference excerpt

Hynobius sonani, the Taichū salamander, is a species of salamander in the family Hynobiidae, endemic to Taiwan, where it occurs in the Central Mountain Range above 2,750 m (9,020 ft). Its natural habitats are from open alpine habitats to shaded moist evergreen forests; it breeds in streams. Adult males are 98–129 mm (3.9–5.1 in) and females are 90–105 mm (3.5–4.1 in) in length. The original specimens used to describe H. sonani (along with H. arisanensis and H. formosanus) were lost in the 1923 Great Kantō earthquake. Hynobius sonani has very fragmented distribution and is threatened by habitat loss, mainly caused by the development of infrastructure for tourism. It is present in Taroko National Park.

Worked examples

Example 1 — a first encounter with Hynobius sonani

Start with the simplest possible case. Write down what Hynobius sonani 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 Hynobius sonani 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 Hynobius sonani 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 Hynobius sonani

In research: Hynobius sonani 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 Hynobius sonani 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: Hynobius sonani is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibians described in 1922, Amphibians of Taiwan, Endangered Fauna of China, so understanding it makes those chapters shorter.
In everyday life: Look for Hynobius sonani 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.
