List of data deficient mammals

List of data deficient mammals 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 List of data deficient mammals rather than just read about it. In short: In September 2016, the International Union for Conservation of Nature (IUCN) listed 783 data deficient mammalian species. Of all evaluated mammalian species, 14% are listed as data deficient.

Key takeaways

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

Reference excerpt

In September 2016, the International Union for Conservation of Nature (IUCN) listed 783 data deficient mammalian species. Of all evaluated mammalian species, 14% are listed as data deficient. The IUCN also lists 31 mammalian subspecies as data deficient. Of the subpopulations of mammals evaluated by the IUCN, four species and/or subpopulations have been assessed as data deficient. This is a complete list of data deficient mammalian species and subspecies evaluated by the IUCN. Species and subspecies which have data deficient subpopulations (or stocks) are indicated. Where possible common names for taxa are given while links point to the scientific name used by the IUCN.

Worked examples

Example 1 — a first encounter with List of data deficient mammals

Start with the simplest possible case. Write down what List of data deficient mammals 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 List of data deficient mammals 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 List of data deficient mammals 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 List of data deficient mammals

In research
List of data deficient mammals 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 List of data deficient mammals 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
List of data deficient mammals is common in secondary-school and first-year university syllabi. It links to neighbouring topics IUCN Red List data deficient species, Lists of animals by conservation status, Lists of mammals, so understanding it makes those chapters shorter.
In everyday life
Look for List of data deficient mammals 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.
