How does the equator affect biodiversity?

What is the effect on biodiversity when we move from pole to equator *?

Speciation is generally a function of time and environmental stability, so if conditions are too harsh, it is difficult for the species to survive and adapt. This results in decrease in biodiversity towards the poles. Species diversity decreases as we move away from the equator towards the poles.

What is the main cause of loss of biodiversity?

Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change.

Why is the equator the hottest?

Why is it hot at the Equator and cold at the poles? Due to the tilt of the Earth, the Equator is closer to the sun so receives more of its energy. The Equator has a smaller surface area so heats up quickly compared to the poles. … This means more heat from the sun makes it to the surface of the Earth.

Why is the equator so important?

The equator is a very important “imaginary line” for the GOES and GOES-R weather satellites. They orbit exactly above the equator, at a very great distance (22,300 miles), which allows them to make just one orbit per day.

How does biodiversity affect the stability of an ecosystem?

Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.

Why is there greater biodiversity in the tropics?

– Tropical latitudes produce more solar power than temperate zones, resulting in high productivity and high diversity of biodiversity. – There are fewer seasonal changes in tropical regions and they have a more or less stable climate. This encourages the specialization of the niche and hence the high wealth of animals.

What happens as we move away from the equator?

Latitude: Temperature range increases with distance from the equator. Also, temperatures decrease as you move away from the equator. This is because the suns rays are dispersed over a larger area of land as you move away from the equator. This is due to the curved surface of the earth.

How can biodiversity be affected?

The main threats facing biodiversity globally are: destruction, degradation and fragmentation of habitats. reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species.
