Life zones of Peru

Life zones of Peru 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 Life zones of Peru rather than just read about it. In short: When the Spanish arrived, they divided Peru into three main regions: the coastal region (11.6% of Peru), that is bounded by the Pacific Ocean; the highlands (28.1% of Peru), that is located on the Andean Heights, and the jungle, that is located on the Amazonian Jungle (Climate of Peru).

Reference excerpt

When the Spanish arrived, they divided Peru into three main regions: the coastal region (11.6% of Peru), that is bounded by the Pacific Ocean; the highlands (28.1% of Peru), that is located on the Andean Heights, and the jungle, that is located on the Amazonian Jungle (Climate of Peru). But Javier Pulgar Vidal (es), a geographer who studied the biogeographic reality of the Peruvian territory for a long time, proposed the creation of eight Natural Regions. In 1941, he presented his thesis "Las Ocho Regiones Naturales del Perú" at the III General Assembly of the Pan-American Institute of Geography and History.

These eight Peruvian regions are:

Chala or Coast (subtropical dry and tropical savanna) Yungas Fluvial Yunga Loma-Vegetation Quechua Suni or Jalca Puna Janca Rupa - Rupa or Highland Jungle Omagua or Lowland Jungle

Example: Andes 10°S See also Altitudinal zonation

Classic version, Amazonic side

Sea level Estimated 22 - 24°C (75°F), but the cold Humboldt Current generates fog on the coast side Tierra caliente (Hot land, tropical) up to 2,500 ft (about 750 m - 1,000 m). Crops: Cacao, Banana, Sugarcane, Manioc, Sweet Potatoes, Yams. Tierra templada (Temperate land, subtropical) up to 6,000 ft (about 1,850 m – 2,000 m) The warmest month has an average temperature of below 22°C or 72°F. Crops: Coffee, Tobacco, Maize, Coca, Peruvian Pepper (Schinus molle), Avocado, Guave (Psidium guajava), Cherimoya, Plum, Citrus fruits. Tierra fría (Cool land, temperate) below 12,000 ft (about 3,600 m, treeline) The warmest month has an average temperature of below 18°C or 64°F. Crops: Potato, Maize, Squash, Passionfruit, Papaya, Peach, Wheat, Rye, and Barley. Farming of cattle. Tierra helada (Cold land) above 12,000 ft (about 3,600 m) The definition of treeline of Coniferae: the warmest month has an average temperature of below 10°C or 50°F ). Crops above tree line: Quinoa, Cañigua, Mashua, Oca, Tarhui, Broad beans and Ulluco. Farming of Sheep, Llamas and Alpacas. Terrestrial Biome Type 10: Montane grasslands and shrublands Tierra Nevada (Janca), above the snow line, 15,000 ft (about 4,500 m - 5,000 m) Just warmer than -1°C over rocks or just warmer than -3°C over snow, annual mean temperature).

Javier Pulgar Vidal's version The Peruvian geographer Javier Pulgar Vidal divided Peru in 8 regions (traditionally, it was costa, sierra and selva): Map from República del Perú - Instituto Geográfico Nacional

Chala (West, Pacific Coast) 0– 500 m Omagua (Lowland jungle or Selva baja, Amazonic rainforest) 80– 400 m Rupa-Rupa (Highland jungle, Selva alta) 400– 1,000 m Yungas (Aymaran for "Warm Lands", Cloud forest) Loma-Vegetation (West, "Yunga coastal" at the north of Peru) 450– 600 m Fluvial Yungas (East, "Yunga fluvial") 1,000- 2,300 m Quechua (East, High valleys) 2,300– 3,500 m Suni (or Jalca or Sallqa too, high plateaus and cliffs) 3,500– 4,100 m Puna (means "mountain top") 4,100– 4,800 m Janca (means white) above 4,800 m, permafrost, rocks, snow and ice

Worked examples

Example 1 — a first encounter with Life zones of Peru

Start with the simplest possible case. Write down what Life zones of Peru 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 Life zones of Peru 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 Life zones of Peru 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 Life zones of Peru

In research: Life zones of Peru 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 Life zones of Peru 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: Life zones of Peru is common in secondary-school and first-year university syllabi. It links to neighbouring topics Altitudinal life zones of Peru, Climatic and glaciological subregions of the Andes, Ecology of the Andes, so understanding it makes those chapters shorter.
In everyday life: Look for Life zones of Peru 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.
