where is the most biodiversity found on earth

So what’s the reason behind this incredible biodiversity? “Exceptions often clarify the rule and our research shows that the environmental history of a place is important to its levels of biodiversity. However, this assertion may be This is true not just for people, but for all life forms on earth. Clearing the land for grazing and crops for animal feed is the main activity that destroys the region. Protecting forests is key to this - they cover almost a third of the global land area and harbour most of the Earth’s terrestrial biodiversity. Biodiversity is the amazing variety of life on Earth. It encompasses diversity on many levels; the vast number of species of plants and animals, the genetic diversity within and between these species and the different biomes and ecosystems of which they are part, including rainforest, tundra and desert. Biodiversity is everywhere, but there are certain habitats and ecosystems around the world that contain a huge variety of plant and animal species found nowhere else on earth. It may sound drastic, but we wouldn’t have human societies without them. Bacteria to baboons, plants to people - the range of life on our planet is incredible. Species richness is the most common metric used in ecology. 22.01.10.

In some environments, virus particles exceed cell numbers by one to two orders of magnitude. For example, the grass in pastures feeds cattle. More than 25 species in the forest are critically endangered. 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. Without plants, there would be no oxygen. The forked watsonia. Areas with extremely high levels of biodiversity are called hotspots. On Earth there are many biomes, and all of them have biodiversity. A highland area, this hotspot initially covered more than 461,000 square km across Mexico and southern U.S. The diversity of plants and animals in Earth's arctic regions is moderate. There are only 35 such regions, called biodiversity hotspots. The level just broader is species diversity, which best fits the literal translation of biodiversity: the number of different species in a particular ecosystem or on Earth. Biodiversity is the abundance and variety of life found on Earth. Co-author of the study, Dr. Colin Beale from the Department of Biology at the University of York, said: “Our research focussed on the incredible diversity of the Cape Floristic Region because the competing theories of stability versus productivity can’t be untangled in the tropics, where both are true. These are Earth’s most biologically rich—yet threatened—terrestrial regions. Biodiversity hotspots are home to unique flora and fauna, most of which are endemic to the particular environment. Forests harbour most of Earth's terrestrial biodiversity. Kirstenbosch Botanical Gardens, Rhodes Drive, Newlands, Cape Town, South Africa. And due to the threat posed to the places on Earth where the most biodiversity exists, hotspots have become even more pivotal to human survival. The Polynesia-Micronesia hotspot has it all, from coastal wetlands and coral atolls to tropical rainforests and beautiful savannas. Coral reefs are the nurseries of the oceans, they are biodiversity hot spots. Other benefits of biodiversity are even more fundamental. -  Designed by Thrive Themes The country harbors between 600,000 and 700,000 different plants and animals. The international team of researchers – including scientists from the University of York (UK), Nelson Mandela University and the University of Cape Town – mapped the distributions of nearly all of the region’s 9400 plant species, from the king protea to the red disa. Learn what you can do to play your part. 52 Chapter 3 … According to experts, this is not surprising, given that hotspots represent the richest and most paramount ecosystems in the world. One of the most famous of these biodiversity hotspots is Madagascar, an island country with an extremely high rate of endemism (species unique to that location). Dr. Curtis Suttle, professor in the Department of Earth, Ocean and Atmospheric Sciences at the University of British Columbia presented a stunning perspective during a talk when he stated, “In a liter of coastal seawater, there are more viruses … Even though forests and other fragmented habitats in hotspots represent just 2.3 percent of Earth’s land surface, they represent one of the most important part of the planet. While biomes with low biodiversity tend to be inhospitable to most life, the biome with the highest biodiversity is inhospitable to most human settlement. The hotspot provides habitat for 8,000 endemic plant species and around 950 birds. It upholds some 4,400 endemic plant species, as well as some of the most fascinating animal species. But the most species aren’t described yet. The rivers and lagoons found within the park are home to the spectacled caiman, American crocodile and bull sharks. This will be the most comprehensive and ambitious biodiversity protection framework in history and aims to do for biodiversity protection what the Paris Agreement on Climate Change did for climate action. Biodiversity underpins all life on Earth. At the broadest most encompassing level, we have ecosystem diversity. d) Bahammas. There are currently 36 recognized biodiversity hotspots. Latin America and Caribbean has seen the most loss, with a 94% drop in average species populations, while Africa comes in second with a 65% drop.. The impact of climate change may be greater on areas where stability has been the norm over extremely long time periods. ... “I found it incredibly exciting as the first visible effects of major evolutionary events started to emerge,” Hoyal Cuthill says. Covering more than 185,427 square km of mountains, alluvial meadows, alpine grasslands, and subtropical forests. It is important as it promotes ecosystem productivity, as well as the sustainability of life in general. A common measure of this variety, called species richness, is the count of species in an area. To qualify as a biodiversity hotspot, an area must meet two strict criteria: Contain at least 1,500 species of vascular plants found nowhere else on Earth … At the equator sufficient rain fall, temperature, etc., favour luxuriant growth of the biodiversity. 15 Most Endangered Species on Earth Our planet, Earth, hosts more than 30 million animal species. Where would you expect to find more biodiversity? Insects are found on land, in water and in air in nearly all habitats and all continents including Antarctica. The loss and degradation of biodiversity negatively affects every level of the planet. Biodiversity: Biodiversity is the variety and differences among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are a part. However, there are places that are severely threatened in spite of being some of the most biologically rich corners on Earth. Keep up with the latest scitech news via email or social media. Although they cover a small area - less than 2% of Earth's surface - rainforests are home to about half the life on Earth. While the rate of loss varies across regions, WWF has identified five major threats that are linked to drops in species populations across all regions:. Similarly, near major ecological boundaries, such as forest to grasslands or shrublands to semi-desert, climate change is likely to cause major, long-lasting loss of biological diversity.”. a) China. But…. We can’t pay Biodiversity, but it does stimulate the economy and help us get a better understanding of that thing. Even though forests and other fragmented habitats in hotspots represent just 2.3 percent of Earth’s land surface, they represent one of the most important part of the planet. Q-30. The South American nation is the most biodiverse country on earth by area, and second overall behind the much larger Brazil. The study found that conservation action does work: in the first analysis of its kind, researchers found that the global biodiversity decline would have … Human interference is also minimum at this place compared to the other places of Northern Hemisphere. Humans share the planet with as many as 8.7 million different forms of life, according to what is being billed as the most accurate estimate yet of life on Earth. Because most coral reef species are more widely distributed than rain forest species, they may be less prone to extinction by the destruction of a single locality. c) 40 million. Even though the area has shrunk severely over the past few decades, it still provides shelter to large populations of wild water buffalo, tigers, elephants and vultures. However, due to coffee and sugar plantations, the forest was decimated to less than 0.1 million square km. The UK government is facing criticism for a lack of progress in hitting major biodiversity targets. 22.01.10. Many different reasons are in Ecuador: Yasuni - the most biodiverse place on Earth? Email address is optional. Some researchers believe that viruses might just be the most successful of earth’s inhabitants. However, a number of those species are at a risk of extinction due to man’s intervention for consumption or entertainment. Recent analysis from The Royal Society for the Protection of Birds (RSPB) has concluded that the UK has fallen severely short on its UN biodiversity objectives that were put forth a decade ago at the Convention of Biological Diversity in Japan. Allow us to introduce you to the unique country of Colombia. The biodiversity quiz is having multiple choice answers, participant must select the correct one either by tick it or circle it.

The biodiversity we see today is the result of 4.5 billion years of evolution and, increasingly, of human influence as well. The findings were published in the Science Advances Journal and used an assessment process […] But why might this be? Australia is 1st in the world for endemics. Coincidentally, the hotspot map overlays extraordinarily on the map of the natural regions that benefit people the most. Biodiversity is not evenly distributed on Earth. Latin America and Caribbean has seen the most loss, with a 94% drop in average species populations, while Africa comes in second with a 65% drop.. They host many endangered or vulnerable populations, all of them highly dependent on the environment to survive. The same hypotheses can explain tropical diversity; there is no need to invoke productivity.”. This is life, this is biodiversity. It upholds some 4,400 endemic plant species, as well as some of the most fascinating animal species. The Amazon rainforest is the most biologically diverse place on Earth. Endemic species—species that are only found in one particular location—are also found in hotspots. A thriving, diverse ecosystem provides many benefits to humans. The findings highlight the threat posed by climate change to some of the most extraordinary places on earth and the importance of giving nature the protection it needs to thrive, the authors of the study say. It’s one of the longest hotspots, crawling in a narrow corridor throughout the eastern coast of Somalia, Kenya, Tanzania and Mozambique. 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. Coniferous Forest Biome – Why They Are Important. A common measure of this variety, called species richness, is the count of species in an area. All this put together is biodiversity: the volume of life on Earth as well as how different species interact with each other and with the physical world around them. Caribbean Islands Hotspot- This Island Hotspot comprises of 30 nations and territories as Anguilla, Bermuda, British Virgi… The conservation of the world's biodiversity is thus utterly dependent on the way in which we interact with and use the world's forests. Life began there. Unfortunately, no less than 25 bird species became extinct in the past 200 years, due to invasive species and overhunting. For example, howler monkeys can be found in the rainforests of Brazil, northern Argentina, and Bolivia. However, if we look only at terrestrial biomes, tropical rainforests have the greatest biodiversity. Without bees, many of our crops would vanish. While the rate of loss varies across regions, WWF has identified five major threats that are linked to drops in species populations across all regions:. For the survival of humanity, we should learn to protect them. All life on Earth hangs on biodiversity. “Our study shows that the environmental stability of south-western South Africa, in conjunction with the region’s rugged topography, explains diversity gradients in the region. Biodiversity is greater inside the world’s protected areas, scientists have been able to show for the first time. Global biodiversity is the measure of biodiversity on planet Earth and is defined as the total variability of life forms. Places … Additionally, most of the species still found alive cannot grow enough to reproduce, "a clear sign that the biodiversity collapse will further continue," says Albano.
