Pelecanimorphae

Pelecanimorphae 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 Pelecanimorphae rather than just read about it. In short: Pelecanimorphae is a clade of aequornithean birds that comprises the orders Ciconiiformes, Suliformes and Pelecaniformes. In the past the name has been used as a synonym for Pelecaniformes.

Key takeaways

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

Reference excerpt

Pelecanimorphae is a clade of aequornithean birds that comprises the orders Ciconiiformes, Suliformes and Pelecaniformes. In the past the name has been used as a synonym for Pelecaniformes. Pelecanimorphae is defined in the PhyloCode by George Sangster and colleagues in 2022 as "the least inclusive clade containing Pelecanus onocrotalus, Sula leucogaster, and Ciconia ciconia". The less inclusive clade Pelecanes was named by Sangster et al, 2022 to unite Pelecaniformes and Suliformes and defined in the PhyloCode as the "least inclusive crown clade containing Pelecanus onocrotalus and Sula leucogaster". This cladogram follows the hypothesis that herons are sister to Pelecani.

Worked examples

Example 1 — a first encounter with Pelecanimorphae

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

In research: Pelecanimorphae 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 Pelecanimorphae 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: Pelecanimorphae is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bird stubs, Neognathae, so understanding it makes those chapters shorter.
In everyday life: Look for Pelecanimorphae 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.
