Ningaui

Ningaui 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 Ningaui rather than just read about it. In short: Ningaui is a genus of small species of the marsupial dasyurid family. Along with the planigales, they are among the smallest marsupials.

Key takeaways

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

Reference excerpt

Ningaui is a genus of small species of the marsupial dasyurid family. Along with the planigales, they are among the smallest marsupials.

Taxonomy The genus was established in 1975 to accommodate two newly described species of dasyurids, the type species Ningaui timealeyi and Ningaui ridei. The author, Mike Archer, compared his specimens to those of Sminthopsis (the dunnarts), distinguishing the new taxon by the structure of the skull, the hindfoot, features of dentition and their smaller size, morphology that was presumed to be specialisations to a more arid environment. The author provided a diagnosis of two species that distinguished the populations by further details of cranial and dental characters. Archer notes the tentative alliance of the species to the genus Planigale by W. D. L. Ride in 1970, and provided a new definition of that genus to separate the new taxa. The three species of the genus are:

Wongai ningaui, Ningaui ridei Pilbara ningaui, Ningaui timealeyi Southern ningaui, Ningaui yvonneae The name "ningaui" refers to a creature from Aboriginal myth. Archer refers to a published story of minute hairy creatures that emerged at night and ate their food uncooked, as an apt description the new genus.

Description A genus of Dasyuridae. The tails of the species are all thin and lack any crest of brush-like fur, and equal to or greater in length than the head-body measurement. All ningaui are nocturnal hunters of invertebrates. In appearance they resemble mice or similar small rodents, but can be distinguished by their pointed snouts. The genus Ningaui was one of the last of the Australian marsupial genera to be erected; this occurred with the surprise discovery of the Wongai ningaui (N. ridei) and the Pilbara ningaui (N. timealeyi) in 1975. All species are found in Australia and restricted to arid regions of the south coast, central deserts and northwest of the continent.

Worked examples

Example 1 — a first encounter with Ningaui

Start with the simplest possible case. Write down what Ningaui 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 Ningaui 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 Ningaui 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 Ningaui

In research: Ningaui 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 Ningaui 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: Ningaui is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dasyuromorphs, Marsupial genera, Marsupials of Australia, so understanding it makes those chapters shorter.
In everyday life: Look for Ningaui 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.

Frequently asked questions

What is Ningaui in simple terms?

Ningaui is a genus of small species of the marsupial dasyurid family. Along with the planigales, they are among the smallest marsupials.

Why does Ningaui matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Ningaui?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
