Tokyo salamander

Tokyo salamander 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 Tokyo salamander rather than just read about it. In short: The Tokyo salamander (Hynobius tokyoensis) is a species of salamander in the family Hynobiidae, endemic to Japan. Its natural habitats are temperate forests, freshwater springs, arable land, irrigated land, and canals and ditches.

Key takeaways

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

Reference excerpt

The Tokyo salamander (Hynobius tokyoensis) is a species of salamander in the family Hynobiidae, endemic to Japan. Its natural habitats are temperate forests, freshwater springs, arable land, irrigated land, and canals and ditches. It is threatened by habitat loss and raccoon (araiguma) predation. Many different species of amphibian have unbalanced sex ratios. This trend is no different in Hynobius Tokyoensis; the sex ratio between males and females is about 1.5:1. Although this does not play as large of a role as habitat destruction when it comes to the decline of this species, it is still significant. Considering their environmental preferences, they are usually found in paddy fields. Mid-Summer drainage from these fields hinders the population's ability to thrive as this would occur before these populations could complete metamorphosis.

Worked examples

Example 1 — a first encounter with Tokyo salamander

Start with the simplest possible case. Write down what Tokyo salamander 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 Tokyo salamander 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 Tokyo salamander 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 Tokyo salamander

In research: Tokyo salamander 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 Tokyo salamander 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: Tokyo salamander is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibians described in 1931, Endemic amphibians of Japan, Hynobius, so understanding it makes those chapters shorter.
In everyday life: Look for Tokyo salamander 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.
