Another part of the explanation of the high biodiversity of certain mountains is linked to the geological dynamics of mountain building. These geological processes, interacting with complex climate changes through time, provide ample opportunities for evolutionary processes to act.
Do mountains have high biodiversity?
Mountains support about one quarter of world’s terrestrial biodiversity and include nearly half of the world’s biodiversity ‘hotspots’. Of the 20 plant species that supply 80 % of the world’s food, six originated in mountains.
What role do mountains play on biodiversity?
Mountains provide for the freshwater needs of more than half of humanity, and are, in effect, the water towers of the world. … Mountain ecosystems are important for biological diversity, particularly in the tropics and warmer temperate latitudes. Isolated mountain blocks are often rich in endemic species.
Why do some regions of the world have high biodiversity?
There are at least three possible scenarios or “routes” that a region may follow to become a biodiversity hotspot: a region can have lots of species because it generates species at faster rates than nearby areas, or because they import species from their surroundings at faster rates (that is, they attract species), or …
What can you say about the biodiversity of this mountain region?
Biodiversity is high in mountain regions because of their wide range of habitats, varied micro-climates, and ecological conditions. These factors have resulted in a high degree of genetic diversity in terms of crop and livestock species and their wild relatives.
Why do mountains matter?
Mountains are the world’s “water towers,” providing 60-80% of all freshwater resources for our planet. At least half of the world’s population depends on mountain ecosystem services to survive – not only water, but also food and clean energy.
Why are mountains important to the environment?
Mountains aren’t just a sight to behold—they cover 22 percent of the planet’s land surface and provide habitat for plants, animals and about 1 billion human beings. The vital landforms also supply critical resources such as fresh water, food and even renewable energy.
What are the benefit of high mountains?
(1) Altitude may fight obesity. (2) It also lowers the risk of heart disease. (3) The mountains inspire physical activity. sleep.
Where are the highest levels of biodiversity on our planet?
Tropical ecosystems support higher levels of biodiversity than temperate or boreal ecosystems. Tropical rainforests and coral reefs are the most diverse ecosystems on the planet. Between 50 and 90 percent of Earth’s plant and animal species are found in tropical regions.
Which region of the Earth has the greatest biodiversity on Earth?
Amazon rain forest has the greatest biodiversity on planet.
Which region has greatest diversity?
Species diversity is greatest in the tropics, particularly in tropical forests and coral reefs. The Amazon basin in South America has the largest area of tropical forests.
