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.
Would you expect to find greater biodiversity near Earth’s poles or near the equator use the term latitudinal gradient in your answer?
Would you expect to find greater diversity near Earth’s poles or near the equator? Toward the equator because of latitudinal gradient.
Where would you expect to find greater biodiversity?
Using this classification, aquatic biomes cover an immense area and therefore a very large number of species. However, if we look only at terrestrial biomes, tropical rainforests have the greatest biodiversity.
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.
Why is there less diversity at the poles?
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.
Which type of area would you expect to find along the equator?
Tropical rainforests are found near the equator due to the amount of rainfall and the amount of sunshine these areas receive. Most tropical rainforests fall between the Tropic of Cancer and the Tropic of Capricorn.
What ecosystem has greater biodiversity?
Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.
Does biodiversity tends to decrease nearer the equator?
Biodiversity tends to decrease nearer the equator. … Climate change can have global, not just local, impacts on biodiversity.
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 factors are present at the equator but not at the poles?
Earth’s Curvature and Temperature
The amount of solar energy in a given area is greater at the equator than in an equal area at the poles, which is why the equator temperature is warmer than the polar temperatures.
How can such diverse habitats be found at one location near the equator?
Another argues that more solar energy is received around the equator, allowing for greater species richness. … A third points out that equatorial tropics are the largest biome, so it makes sense that there would be more species.
