Frequent question: Does biodiversity decrease closer to the equator?

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 happens to biodiversity near the equator?

Today, plant and animal biodiversity across the globe tends to be highest at the equator and diminishes as one moves to higher latitudes. This pattern, called the latitudinal diversity gradient, has not always existed, new research finds.

Does biodiversity increase near the equator?

Biodiversity increases towards the equator because the equator has a favorable climate rich in nutrients and sunlight that promotes the development of…

Does biodiversity decrease near the equator?

This idea is also referred to as the latitudinal diversity gradient, meaning that as you move from the equator towards the poles, diversity lessens. … That the are is relatively stable in terms of environment when compared to polar regions has also been suggested as a reason for increased biodiversity at the equator.

Why does biodiversity decrease away from the 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 happens in the equator?

If you live on the equator you will experience the quickest rates of sunrise and sunset in the world, taking a matter of minutes. These places also have a constant twelve hours of day and night throughout the year, while north or south of the equator day length increasingly varies with the seasons.

Is it better to live closer to the equator?

It’s a question some researchers recently tackled at the University of Vermont. They found ‘happiness rises and falls with distance from the equator. ‘ In other words, the closer you live to the equator the happier you feel.

Why does biodiversity tend to be higher in areas closest to the equator or tropical areas quizlet?

Why are areas near the equator have more species richness? Greater amounts of solar energy, heat, and humidity at tropical latitudes lead to more plant growth, making areas nearer the equator more productive and able to support larger numbers of animals.

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 do more species live near the equator?

Biologists have long noted that life’s majesty grows grander and grander the closer you are to the equator. “Nearly all groups of organisms, from foraminifera to frogs, are most diverse in the tropics. … Another argues that more solar energy is received around the equator, allowing for greater species richness.

Why does biodiversity increase towards the tropics?

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

Does biodiversity increase as you go up a mountain?

Unique Biodiversity

Because mountain habitats can change quickly as elevations increase, they are often home to a greater diversity of plants and animals than nearby lowlands.

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.
