Does biodiversity increase with increasing latitude?

How does latitude affect biodiversity?

Biodiversity higher in the tropics, but species more likely to arise at higher latitudes. Summary: … The results suggest that the latitudinal diversity gradient may be due higher species turnover — speciation counterbalanced by extinction — towards the poles than near the equator.

Why is biodiversity higher in lower latitudes?

[1] Low-latitude areas have a greater incidence of solar energy, and often a higher air moisture content than higher-latitude areas. This fuels an elevated primary-productivity, providing more resources to the ecology as a whole, enabling competition, specialization and speciation.

Which latitude will have more biodiversity?

For more than three centuries Western science has known that biodiversity is greatest in the tropics. European explorers and traders returned from Africa, Asia and the Americas with thousands of specimens of previously unknown kinds of animals and plants.

How does diversity change with latitude and altitude?

The decrease in diversity when moving from lower latitudes towards higher latitudes is referred to as Latitudinal Diversity Gradient. Generally it is observed that the diversity richness is more in the areas near the equator than at the poles. … Altitude also affects the diversity richness inversely.

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 does biodiversity increase as you get closer to 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.

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.

Why species diversity is highest at the equator compared to higher latitudes?

A new study led by Oxford Earth Sciences’ Associate Professor Erin Saupe suggests that higher species diversity in equatorial regions may be caused by higher rates of speciation (the formation of new and distinct species in the course of evolution), driven by changes in precipitation across space and through time.

What is the relationship between diversity and latitude quizlet?

What is the relationship between diversity and latitude? As latitude increases, moving away from the equator at the center of the Earth toward either the North Pole or the South Pole, biodiversity decreases.

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.

Does biodiversity increase with precipitation?

In the woody flora across California, taxonomic diversity increased with increasing mean annual rainfall at the regional, site (four plots), and plot scales, with the steepest slope at the largest scale (Fig. 2).
