Silver marsupial frog

Silver marsupial 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 Silver marsupial frog rather than just read about it. In short: The silver marsupial frog, plumbeous marsupial frog, or rana marsupial de plumbea (Gastrotheca plumbea) is a species of frog in the family Hemiphractidae. It is endemic to the Pacific slopes of Andes in northern and central Ecuador.

Key takeaways

Silver marsupial 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 Silver marsupial frog to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Silver marsupial frog from memory before moving on to harder problems.

Reference excerpt

The silver marsupial frog, plumbeous marsupial frog, or rana marsupial de plumbea (Gastrotheca plumbea) is a species of frog in the family Hemiphractidae. It is endemic to the Pacific slopes of Andes in northern and central Ecuador.

Description The adult male frog measures 42.1–61.0 mm long in snout-vent length and the adult female frog 58.2–73.0 mm. The skin of the dorsum is green in color with or without marks. The throat can be light green or yellow-brown in color. There is brown color on the legs with bronze marks. The feet are green or brown in color. The belly is broze or brown or yellow-green during the day and cream-white at night. Where the legs meet the body, thre is bronze and blue or green and blue color during the day and blue by itself at night. The iris of the eye is light olive-green in color.

Etymology Scientists gave the frog the Latin name plumbeus, for the metal lead, because the holotype appeared lead-gray in color in preservative.

Habitat This frog is arboreal and nocturnal. It lives in cloud forests but people sometimes see it in secondary forest. Scientists have seen the frog between 1,300 and 3,200 m (4,300 and 10,500 ft)above sea level. Scientists have reported the frog in protected places: Reserva Ecológica Los Ilinizas, Reserva Ecológica Cotacachi-Cayapas, Estación Científica Río Guajalito, Bosque Protector Mindo-Nambillo, and Bosque Protector Cashca Totoras.

Reproduction The female frog carries her eggs in a pouch on her back. Scientists have seen 20 to 28 eggs on one female at a time. After 8-10 months, the young emerge as small froglets. This frog is a direct developer with no free-swimming tadpole stage.

Threats The IUCN classifies this species as vulnerable to extinction. The principal threat is habitat loss associated with agriculture, logging, and cattle cultivation.

Worked examples

Example 1 — a first encounter with Silver marsupial frog

Start with the simplest possible case. Write down what Silver marsupial 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 Silver marsupial 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 Silver marsupial 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 Silver marsupial frog

In research: Silver marsupial 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 Silver marsupial 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: Silver marsupial frog is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibians described in 1882, Amphibians of the Andes, Arboreal amphibians, so understanding it makes those chapters shorter.
In everyday life: Look for Silver marsupial 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.
