List of vulnerable arthropods

List of vulnerable arthropods 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 vulnerable arthropods rather than just read about it. In short: In July 2016, the International Union for Conservation of Nature (IUCN) listed 1080 vulnerable arthropod species. Of all evaluated arthropod species, 11% are listed as vulnerable.

Key takeaways

  • List of vulnerable arthropods 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 vulnerable arthropods to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of List of vulnerable arthropods from memory before moving on to harder problems.

Reference excerpt

In July 2016, the International Union for Conservation of Nature (IUCN) listed 1080 vulnerable arthropod species. Of all evaluated arthropod species, 11% are listed as vulnerable. The IUCN also lists 29 arthropod subspecies as vulnerable. No subpopulations of arthropods have been evaluated by the IUCN. For a species to be assessed as vulnerable to extinction the best available evidence must meet quantitative criteria set by the IUCN designed to reflect "a high risk of extinction in the wild". Endangered and critically endangered species also meet the quantitative criteria of vulnerable species, and are listed separately. See: List of endangered arthropods, List of critically endangered arthropods. Vulnerable, endangered and critically endangered species are collectively referred to as threatened species by the IUCN. Additionally 2875 arthropod species (30% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed". This is a complete list of vulnerable arthropod species and subspecies as evaluated by the IUCN.

Worked examples

Example 1 — a first encounter with List of vulnerable arthropods

Start with the simplest possible case. Write down what List of vulnerable arthropods 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 vulnerable arthropods 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 vulnerable arthropods 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 vulnerable arthropods

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