Why Is Biodiversity Higher In Tropics

There are more species in the tropics because tropical ecosystems have more niches. Tropical areas are rich in biodiversity than temperate regions because.

Effects Of Habitat Disturbance On Tropical Forest Biodiversity Pnas

Why is biodiversity so high in the tropical rainforest.

Why is biodiversity higher in tropics. Another explanation for this avian latitudinal diversity gradient is the climate stability hypothesis. Warm temperature and high humidity of tropical region are favourable for most of the species on earth. The most biodiverse ecosystems are generally ones closer to the equator and lower in altitude.

Soil nutrient is poor in tropical rain forests because the sunlight that is intended to reach the floor of the tropical forest is blocked by the tall and dense trees. Scientists dont know why biodiversity tends to concentrate around tropical regions but they have put forward several hypotheses. The hot and wet climate provides ideal conditions for many species of plants and animals to thrive.

There are several key reasons for high biodiversity in tropical ecosystems. The presence of natural enemies that target specific species and keep population size. First is the constant temperature and climate.

Biodiversity is high because the warm and wet consistent climate in tropical rainforests is able to sustain life in all different forms. The results suggest that the latitudinal. Why is biodiversity such a hot issue.

As an ecosystem the Amazon is one of the most biodiverse places on earth. The increase in species richness from the poles to the tropics referred to as the latitudinal diversity gradient is one of the most ubiquitous biodiversity patterns in the natural world. Despite this gap in understanding it is generally accepted that the tropics do have a higher rate of net species diversification resulting from the difference between the formation and the loss of species.

For example a tropical rainforest or a coral reef. There are a number of reasons for biodiversity in the tropical rainforest including. The tropics represent a fraction of the earths surface area but are the epicenter of incredible plant and animal dive.

However the number of niches in an ecosystem is determined by the number of. It is generally seen that there is more biodiversity in the tropical region than the temperate region because of a variety of factors. Researchers found that while the tropics harbor more species the number of subspecies increases in the harsher environments typical of higher latitudes.

In other words high biodiversity in the tropics is a result of efficient usage of available nutrients not necessarily a large amount of nutrients. High NPP directly contributes to α-diversity by supporting more species with minimum viable populations whereas enlarged populations of each organism increase overall mutation frequency and hence intraspecific genetic variation. This hypothesis suggests that the stable environment.

As you move towards higher latitudes and altitudes biodiversity tends to decline. The temperate region has a severe climate which makes it very hard for animals to survive in such extreme climatic condition. Tropical areas have more stable climate than temperate regions.

And postdoctoral researchers in the laboratory of Brian Enquist and the leading authors of the special issue. Perhaps they posited the astonishing plant diversity we find in tropical forests is enabled by two factors. In a study supported by the National Evolutionary Synthesis Center in North Carolina researchers found that while the tropics harbor a greater diversity of species the number of subspecies --.

Complete answer to this is here. Over time species radiated from their tropical origins so many temperate groups have tropical ancestors. One idea is that tropical regions harbor greater biodiversity because they are especially fertile grounds for the formation of new speciesie cradles of diversity Another idea is that.

It has long ago been proposed that the higher species diversity in the tropics could be explained by a larger number of habitats available for the organisms living there said Christine Lamanna and Cyrille Violle both recent PhD. Why biodiversity is rich in tropics. Over 3 million species live in the rainforest and over 2500 tree species or one-third of all tropical trees that exist on earth help to create and sustain this vibrant ecosystem.

More and more biodiversity is at risk.
