Why biodiversity is greater 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.

Why is biodiversity higher in lower latitudes?

Species density is higher in the tropics (low latitude) than in temperate regions (high latitude) resulting in a latitudinal biodiversity gradient (LBG).

At which latitude is biodiversity the greatest?

So why is life most diverse in the tropics? The number of hypotheses to explain the latitudinal diversity gradient (LDG) has only increased in recent decades. Pianka (1966) listed 6, Brown (1988) 8, Rohde (1992) 23, Willig et al. (2003) 27, and Lomolino et al.

Does biodiversity decrease with latitude?

Species richness, or biodiversity, increases from the poles to the tropics for a wide variety of terrestrial and marine organisms, often referred to as the latitudinal diversity gradient (LDG).

Why is biodiversity greater 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.

What are the reasons for 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 generally happens to biodiversity as the latitude increases?

1600. Species richness in both terrestrial and marine environments generally declines with latitude. … The species richness of terrestrial plants and animals generally increases with elevation.

What is the most important reason for decrease in biodiversity?

The most important reason for the decrease in Biodiversity is habitat destruction. Habitat destruction is also called habitat loss and habitat reduction. Habitat destruction is a process by which a natural habitat becomes incapable of supporting its native species.

Where does biodiversity tend higher?

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 does latitude affect a regions 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.

How does a species diversity vary with latitude?

Explanation: This idea is also referred to as the latitudinal diversity gradient, meaning that as you move from the equator towards the poles, diversity lessens. This pattern is one of the oldest observed in ecology.

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.

Why does biodiversity decrease towards the poles?

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.

Why is more biodiversity better?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. … Healthy ecosystems can better withstand and recover from a variety of disasters.

Why is there less diversity at the poles?

Any organisms in the poles must be able to withstand a cold, harsh climate. There are much less diverse food chains and webs that exist in these locations. Climate is a big factor in determining which biomes on the planet have greater biodiversity.
