How does altitude affect biodiversity?

How does altitude impact biodiversity?

Researchers have shed light on how a changing altitude affects the evolutionary history and biodiversity of plants. … The researchers found that plant biodiversity initially increases with altitude, until it reaches a diversity peak at around 1 300 to 1 800 m, after which point it decreases with altitude.

Does altitude affect plant diversity?

Dwarf shrub cover was the main driver of plant diversity, whereas elevation did not affect species richness or beta-diversity. These findings suggest that elevation directly influences V. myrtillus growth but not plant diversity.

How do mountains affect biodiversity?

Mountains, with their uniquely complex environments and geology, have allowed the continued persistence of ancient species deeply rooted in the tree of life, as well as being cradles where new species have arisen at a much higher rate than in lowland areas, even in areas as amazingly biodiverse as the Amazonian …

Why does biodiversity decrease with altitude?

(1), the authors suggested that species richness decreases at high levels of habitat diversity because the area available per habitat decreases [area–heterogeneity tradeoff hypothesis (AHTO)].

How does altitude affect landscape?

The higher your garden’s elevation, the lower the air pressure. Air pressure has an effect on plant growth in a number of ways. Lower air pressure has less carbon dioxide, which plants need to grow, and it also means a slower rate of transpiration.

How does altitude affect the kind of vegetation soil type and crop production?

The more important factor limiting plants at higher elevations is the length of the growing season. … Plants can’t photosynthesize below a certain temperature threshold, but this varies across species. Many high-elevation plants are able to conduct photosynthesis at colder temperatures than low-elevation plants.

How does altitude affect agriculture?

At such times of the day, plants growing at high elevations have a relative advantage, as incident sunlight increases with altitude. … This results in closure of stomata and hence reduction in photosynthesis and may also bring about a more xeromorphic plant species composition (Cohen et al., 1981).

How does latitude and altitude affect biomes?

As latitude and altitude increase, biomes and vegetation change. Trees of tropical rainforests usually grow closer to the equator, while mosses and lichen of the tundra grow closer to the poles.

How does altitude affect soil type?

The study revealed that the moisture content and water holding capacity of soil increased with increasing altitudes while bulk density (BD) reduced with increasing altitude. The higher proportion of soil texture was contributed of sand > clay > silt in each altitude. The soil pH of entire forest was acidic in nature.

What is the impact of latitude and altitude on the distribution of biodiversity?

With the change in altitude and latitude there is a change in the sunlight distribution patterns which indirectly affects the viability and germination of the seeds. So plants thriving in areas with low light intensity will survive more in high altitude region and vice versa and hence more widely distributed.

Why does the type of vegetation change with altitude?

Answer: Elevation may affect the type and amount of sunlight that plants receive, the amount of water that plants can absorb and the nutrients that are available in the soil. As a result, certain plants grow very well in high elevations, whereas others can only grow in middle or lower elevations.

Why do mountains have more biodiversity?

Another part of the explanation of the high biodiversity of certain mountains is linked to the geological dynamics of mountain building. These geological processes, interacting with complex climate changes through time, provide ample opportunities for evolutionary processes to act.

Why do mountains have higher biodiversity?

Three main factors that link high diversity patterns to mountain systems are precipitation levels, gradients in environmental variables (elevational and climatic gradients), and environmental heterogeneity.
