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

Where are the tropics the most diverse areas?
The geographical area of the Mexican tropic has the most diverse ecosystems on Earth (most species in a given area), and also the most fragile. It is also the area with the great cultural richness, for which reason it has been classified as one of the regions with the greatest biocultural diversity.

Why are the tropics the most diverse areas quizlet?
The tropics harbour the highst rates of speciation (new species origination) & also have lower rates of extinction than speciation. Therefore, this generates high diversity as many species as being ‘born’ whilst few are disappearing.

What is one reason for more species diversity in the tropics?
One reason there is more species diversity in the tropics is: there is more solar energy available in the tropics than in the temperate zones.

Why there is greater biodiversity in tropics than temperate areas?
Greater biodiversity of the tropics is due to the following reasons: Tropics receive more solar energy which contributes to greater productivity and hence greater biodiversity due to greater availability of food. Less seasonal variations promote niche specialisation and lead to a greater species diversity.

What are the reason for species diversity?
What Causes Species Diversity? Species diversity is caused by evolution. A region becomes diverse with the evolution of different species in an area.

What are the tropics the most diverse areas?
The tropics are the most diverse region on Earth, hosting about 80% of the planet’s terrestrial species and over 95% of its corals and mangroves. Diverse and healthy natural ecosystems provide benefits vital for life on Earth and human wellbeing and prosperity.

Where are the tropics located?
The tropics are regions of 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.

Where would you expect more species biodiversity in tropics or in polar regions?
For more than three centuries Western science has known that biodiversity is greatest in the tropics.

Why are tropical regions warmer than temperate regions?
The tropics are warm all year, averaging 25 to 28 degrees Celsius (77 to 82 degrees Fahrenheit). This is because the tropics get more exposure to the sun. Because of all that sun, the tropics don’t experience the kind of seasons the rest of Earth does.

At what latitude would you find the greatest amount of biodiversity?
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.

Why are temperatures higher in the tropics than they are the poles quizlet?
Why are the tropics warm, and the poles cold? The tropics are warmer than temperate regions because the sun’s rays arrive almost perpendicular to regions near the equator. Near the poles, the angle of incidence of the sun’s rays spreads them out over a much greater area, providing less energy per unit area.

What is beta diversity in a region quizlet?
β (beta) diversity = the difference in species from one habitat to the next (turnover). High beta‐diversity implies low similarity between species composition of different habitats (e.g., reefs inside and outside reserves). Gamma diversity: – a measure of the overall diversity within a large region.

Does temperate or tropical have more biodiversity?
It is generally seen that there is more biodiversity in the tropical region than the temperate region because of a variety of factors: First is the constant temperature and climate. The temperate region has a severe climate which makes it very hard for animals to survive in such extreme climatic condition.

Why is species diversity greater in tropical regions than in temperate or polar regions?
The species diversity is rich in tropical regions due to the availability of sufficient sunlight and water. The species of tropical regions also have a longer evolutionary history.

Why is greater biological diversity at the tropics mainly?
their greater biological diversity? a. Unlike temperate regions subjected to frequent glaciations in the past, tropical latitudes have remained relatively undisturbed for millions of years and thus, had a long evolutionary time for species diversification.
