Lorius

Lorius 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 Lorius rather than just read about it. In short: Lorius is a genus of lory in the parrot family Psittaculidae. The genus contains six species that are distributed from the Moluccas in Indonesia through New Guinea to the Solomon Islands.

Key takeaways

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

Reference excerpt

Lorius is a genus of lory in the parrot family Psittaculidae. The genus contains six species that are distributed from the Moluccas in Indonesia through New Guinea to the Solomon Islands. They have characteristic red plumage with varying amounts of blue (and in some yellow and white), green wings, and in all but one species a black crown. The bills are orange and the feet are grey. With lengths of up to 25 to 30 cm (9.8 to 11.8 in) and average weights of 132 to 190 g (4.7 to 6.7 oz), the members of this genus tend to be the largest of the Loriinae subfamily.

Taxonomy The genus Lorius was introduced in 1825 by the Irish zoologist Nicholas Aylward Vigors with the purple-naped lory as the type species. The word "lory" comes from the Malay lūri, a name used for a number of species of colourful parrots. The word was used by the Dutch writer Johan Nieuhof in 1682 in a book describing his travels in the East Indies. The spelling "laurey" was used by English naturalist Eleazar Albin in 1731 for a species of parrot from Brazil, and then in 1751 the English naturalist George Edwards used the spelling "lory" when introducing names for five species of parrot from the East Indies in the fourth volume of his A Natural History of Uncommon Birds. Edwards credited Nieuhof for the name.

Species The genus contains six species.

Worked examples

Example 1 — a first encounter with Lorius

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

In research: Lorius 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 Lorius 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: Lorius is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bird genera, Lorini, Lorius, so understanding it makes those chapters shorter.
In everyday life: Look for Lorius 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 Lorius in simple terms?

Lorius is a genus of lory in the parrot family Psittaculidae. The genus contains six species that are distributed from the Moluccas in Indonesia through New Guinea to the Solomon Islands.

Why does Lorius 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 Lorius?

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.
