Where does Earth’s biodiversity peak?

Biodiversity is a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth, and is richer in the tropics.

Where is Earth’s biodiversity the greatest?

The area on Earth considered to have the greatest biodiversity is the Tropical Andes region covering 1,258,000 km² (485,716 miles²) and running through Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and a small area of northern Argentina.

When was the peak of the Earth’s biodiversity?

The tendency for species diversity to be greatest near the Equator developed 34 to 48 million years ago during the Eocene Epoch, Museum scientists have found. This global distribution pattern of species is a major feature of biodiversity today.

Where is the world’s highest concentration of biodiversity reside?

Brazil is considered THE most biodiverse country on the planet – where one-tenth of the world’s overall species call home.

Where is Earth’s greatest biodiversity quizlet?

Why is Earth’s biodiversity greatest near the equator? More species can live in warm climates than in cold climates.

How is biodiversity distributed across the earth?

Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions. Among other factors, the diversity of all living things (biota) depends on temperature, precipitation, altitude, soils, geography and the presence of other species.

What is the origin of biodiversity?

History of Biodiversity. … Charles Darwin [2] identified the first principle of the origin of modern biodiversity, namely that all species were linked in a single great phylogeny, or tree of life, and that all could be traced back to a presumed single original species at some distant time in the geological past.

How many biodiversity centers are there in the world?

There are 34 areas around the world which are qualified as Biodiversity hotspots.

Which of the following countries has highest biodiversity?

Brazil is the only country with highest biodiversity. Biodiversity accounts one-tenth of the world’s overall species.

What ecosystem has the highest biodiversity in the world?

Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest.

Which of the following has the highest biodiversity?

Brazil. It is the country with the greatest biodiversity of flora and fauna on the planet. Brazil has the highest number of species of known mammals and freshwater fish, and more than 50,000 species of trees and bushes, it takes first place in plant diversity.

Why is the Earth’s biodiversity greatest near the equator?

There might be more biodiversity near the equator because it’s warmer year round, allowing organisms to continue growing. Locations away from the equator will have cold winters that will slow growth for microorganisms, plants and animals.

Is there more biodiversity on Earth near the equator or pole?

Species diversity is higher at the equator than at the poles. In biological terms, this is referred to as the latitudinal diversity gradient (LDG), in which the number of species increases from the poles to the Equator. This ranks among the broadest and most notable biodiversity patterns on Earth.
