Harrisoniella hopkinsi

Harrisoniella hopkinsi is a science 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 Harrisoniella hopkinsi rather than just read about it. In short: Harrisoniella hopkinsi is a species of phtilopterid louse that lives on and eats the feathers of albatrosses. The species was first described by W.

Key takeaways

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

Reference excerpt

Harrisoniella hopkinsi is a species of phtilopterid louse that lives on and eats the feathers of albatrosses. The species was first described by W. Eichler in 1952. This species is dark brown with an elongated head, and extremely large – H. hopkinsi is one of the largest feather lice, with males reaching up to 9 millimetres (0.35 in) long. They live mostly on the wing feathers, but are quite able to move if disturbed or if their host bird should die. There are usually fewer than half a dozen adult specimens found on a single host bird; low compared with other species of feather lice, which may number in the hundreds. Harrisoniella hopkinsi has been found on the feathers of the wandering albatross (Diomedea exulans) and the southern royal albatross (Diomedea epomophora).

Worked examples

Example 1 — a first encounter with Harrisoniella hopkinsi

Start with the simplest possible case. Write down what Harrisoniella hopkinsi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Harrisoniella hopkinsi 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 Harrisoniella hopkinsi 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 Harrisoniella hopkinsi

In research: Harrisoniella hopkinsi appears in science 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 Harrisoniella hopkinsi 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: Harrisoniella hopkinsi is common in secondary-school and first-year university syllabi. It links to neighbouring topics Insects described in 1952, Lice, Louse stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Harrisoniella hopkinsi 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.
