India is the world’s 8th most biodiverse region with a 0.46 BioD score on diversity index, 102,718 species of fauna and 23.39% of the nation’s geographical area under forest and tree cover in 2020.
What are biodiversity patterns?
Biodiversity pattern in species is understanding that the number of species found on Earth vary globally, locally as well as with time. Many variations can be present within species, biomes, ecosystems and a particular area. 3.
Which is well known pattern of biodiversity?
Latitudinal gradient – This is the most well-defined and well-known pattern of biodiversity studies till date. According to this pattern, the species diversity follows a regular pattern as we move from the equator to the polar regions.
What is the pattern of biodiversity class 12?
Species diversity decreases as we move away from the equator towards the poles. Tropics harbor more species than temperate or polar areas. Colombia located near the equator has nearly 1,400 species of birds while New York at 41° N has 105 species and Greenland at 71° N only 56 species.
What is global pattern of biodiversity?
Biodiversity is the degree of variation of life forms within a given ecosystem, biome, or an entire planet. Biodiversity is a measure of the health of ecosystems. Biodiversity is in part a function of climate. In terrestrial habitats, tropical regions are typically rich whereas Polar Regions support fewer species.
What is biodiversity explain patterns of biodiversity?
Biodiversity is the variety observed in organisms at every level of biological organization. As ecologists studied biodiversity in the environment, they observed a regular pattern in which diversity was distributed over the entire area of the planet.
What are the three patterns of biological diversity?
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms.
Does biodiversity follow any patterns?
Does species diversity follow any patterns? The diversity of species is lowest at the poles and increases toward the equator, with the deserts being obvious exceptions. Tropical rainforests and coral reefs are among the planet’s richest and most complex ecosystems.
Which is the most well known pattern?
Checkered. One of the most popular and instantly recognizable patterns on the market, checked, or checkered, fabrics feature a simple checkerboard-style design with alternating colored squares.
What is diversity and biodiversity?
The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.
What are different patterns of biodiversity describe latitudinal gradients?
Latitudinal gradients of biodiversity are biogeographic patterns that define the way in which components of taxonomic, phylogenetic, functional, genetic, or phenetic dimensions change with latitudinal position on the surface of the earth.
How many hotspots are there in India?
India has four biodiversity hotspots, i.e., Eastern Himalayas, Western Himalayas, Western Ghats and Andaman and Nicobar Islands.
What are the global and Indian patterns of biodiversity?
It says that the species richness increases as we go from poles to the tropics. But in deserts , Tropical region is rich in species diversity. For example – Columbia has 1400 bird species where as India has 1200 bird species. Moreover Tropical Forest has greater species diversity than temperate forest.
What are some of the major global patterns in biodiversity?
This includes patterns in hotspots and coldspots (highs and lows) of diversity (including comparisons between biological realms and between biogeographical regions), variation with spatial scale (for example, species–area relationships and relationships between local and regional richness) and along gradients across …
What is importance biodiversity?
Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.
