Phrynomedusa marginata

Phrynomedusa marginata 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 Phrynomedusa marginata rather than just read about it. In short: Phrynomedusa marginata, the bicolored leaf frog, is a species of frog in the subfamily Phyllomedusinae. It is endemic to Brazil.

Key takeaways

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

Reference excerpt

Phrynomedusa marginata, the bicolored leaf frog, is a species of frog in the subfamily Phyllomedusinae. It is endemic to Brazil. People have seen it between 600 and 800 meters above sea level. This arboreal frog lives in the canopy in Atlantic rainforests. The female frog lays eggs in cracks in the rock over water. When the eggs hatch, the tadpoles fall into the water below. Scientists consider this critically endangered because it did not recover from a precipitous population drop that occurred after the fungal disease chytridiomycosis in its habitat in the 1980s or 1990s. They also revised the frog's numbers because many individuals counted as P. marginata in previous surveys have since been classified as P. dryade. The frog is also threatened by deforestation associated with agriculture, urbanization, and grazing. Scientists say that if the frog should be discovered again, it should be collected for an ex situ breeding program, the offspring relocated to suitable habitat.

Worked examples

Example 1 — a first encounter with Phrynomedusa marginata

Start with the simplest possible case. Write down what Phrynomedusa marginata 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 Phrynomedusa marginata 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 Phrynomedusa marginata 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 Phrynomedusa marginata

In research: Phrynomedusa marginata 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 Phrynomedusa marginata 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: Phrynomedusa marginata is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibians described in 1976, Amphibians of the Atlantic Forest, Arboreal amphibians, so understanding it makes those chapters shorter.
In everyday life: Look for Phrynomedusa marginata 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.
