How much of the world’s biodiversity is in the tropics?

Tropical forests are incredibly biodiverse; they support at least two-thirds of the world’s biodiversity (1) despite covering less than 10% of Earth’s land surface (2).

How much biodiversity is in the tropics?

More than two thirds of the world’s biodiversity resides in tropical regions, providing important ecosystem functions and services at global and local levels.

What percent of species are in the tropics?

The tropics are home to nearly 80 percent of all species in the world. Those species, in their perennial warm temperatures, face the double punch from both human pressures, such as overfishing or logging, and environmental abuse, from droughts and heatwaves fueled by climate change.

Is there more biodiversity in the tropics?

The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity.

What percentage of the world’s known biodiversity can be found in tropical rainforests?

Biologists estimate that tropical rainforests contain about 50% of the world’s terrestrial plant and animal species, yet they encompass only about 6% of the world’s land area.

What are the tropics of the world?

The tropics are regions of the Earth that lie roughly in the middle of the globe. The tropics between the latitude lines of the Tropic of Cancer and the Tropic of Capricorn. The tropics include the Equator and parts of North America, South America, Africa, Asia, and Australia.

Why is biodiversity highest in the tropics?

The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity.

Which ecosystem has highest biodiversity?

Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than 25% of all marine life.

What percentage of the world’s plant and animal species can be found in tropical rainforests?

Because tropical rain forests are some of the oldest ecosystems on earth, they are home to a diverse population of plants and animals. In fact, around 50% of the world’s plants and animals can be found here—with new species still being discovered.

What percentage of living species live in tropical forests?

About 80% of the world’s documented species can be found in tropical rainforests, even though they cover only about 6% of the Earth’s land surface – less than half the area they covered not so very long ago.

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.

What is tropical biodiversity?

It is estimated that tropical forests contain more than half the species on Earth. The tropics represent a remarkable biodiversity, including plants, birds, insects like especially ants, beetles, butterflies and termites; amphibians, mammals, and other organism groups.

Why is biodiversity so high in the tropical rainforest?

Explanation: The high species richness or biodiversity found in tropical rain forests is mainly due to their geographic location and the amount of precipitation they receive. Tropical rainforests fall along the equator and receive a large amount of precipitation.

How many species live in the tropical rainforest?

Over 3 million species live in the rainforest, and over 2,500 tree species (or one-third of all tropical trees that exist on earth) help to create and sustain this vibrant ecosystem. More and more, biodiversity is at risk.

How much of the world’s surface is covered by rainforest?

Rainforests are Earth’s oldest living ecosystems, with some surviving in their present form for at least 70 million years. They are incredibly diverse and complex, home to more than half of the world’s plant and animal species—even though they cover just 6% of Earth’s surface.

How many of the world’s species live in the rainforest?

No one knows exactly how many species live in the world’s tropical rainforests — estimates range from 3 to 50 million species — rainforests are the undisputed champions of biodiversity among the world’s ecosystems, containing far higher numbers of species on a per-area basis relative to sub-tropical, temperate, and …
