Tyler's tree frog

Tyler's tree frog 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 Tyler's tree frog rather than just read about it. In short: Tyler's tree frog or the southern laughing tree frog (Pengilleyia tyleri) is an arboreal species of tree frog. It is native to eastern Australia where it occurs from south-eastern Queensland to the southern coast of New South Wales.

Key takeaways

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

Reference excerpt

Tyler's tree frog or the southern laughing tree frog (Pengilleyia tyleri) is an arboreal species of tree frog. It is native to eastern Australia where it occurs from south-eastern Queensland to the southern coast of New South Wales. It is generally a coastal species and is not found inland.

Etymology The specific name tyleri honours Michael J. Tyler, an Australian herpetologist.

Description

This frog is grey-brown to fawn (of various shades) on its dorsal surface, and a whitish-yellow on its ventral surface. Females are larger than males and reach a maximum size of about 50 mm. It has green flecks on the back. The iris is golden in colour and it has cross-shaped pupils. This species is very similar to the Peron's tree frog, (Pengilleyia peronii). The easiest way to tell them apart is by call, but P. peronii has strong black and yellow marbling in the thighs, armpits, hands and feet. P. tyleri has only faint yellow and brown marbling in the legs and armpits, lacking marbling in the hands and feet. This species lacks a strong black line above the tympanum, this line is present in P. peronii. As it is an arboreal frog, the toe pads are larger than its toes and fingers, allowing it to grip well on branches. Its hands are partially webbed, its toes are completely webbed, and the tympanum is visible. During breeding, males can turn a very strong yellow colour.

Ecology and behaviour This species inhabits coastal forest and cleared land. It is normally found around permanent dams, swamps, and ponds. Males call from vegetation around the water body during spring and summer, often after rain. The call of this species resembles a short laughing noise, similar to that of the Peron's tree frog, but without a downward inflection.

As a pet In Queensland and New South Wales, this animal may be kept in captivity with the appropriate permit.

Worked examples

Example 1 — a first encounter with Tyler's tree frog

Start with the simplest possible case. Write down what Tyler's tree frog 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 Tyler's tree frog 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 Tyler's tree frog 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 Tyler's tree frog

In research: Tyler's tree frog 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 Tyler's tree frog 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: Tyler's tree frog is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibians described in 1979, Amphibians of New South Wales, Amphibians of Queensland, so understanding it makes those chapters shorter.
In everyday life: Look for Tyler's tree frog 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.
