Keep up with the latest scitech news via email or social media. The hotspot provides habitat for 8,000 endemic plant species and around 950 birds. Home to many endangered primates, the coastal forests are mainly under threat by unbridled agricultural expansion. Without bees, many of our crops would vanish. At the equator. Biodiversity also describes ecosystems or environments that contain a high degree of this variation — for example, the Amazon rainforest. This park has 500 tree species and various species of wildlife. found in a particular location and nowhere else; fully 25% of Hawaiian coral species are endemic to the area (Pacific Whale Foundation 2003). Q-30. The word biodiversity is a contraction of 'biological diversity'. Our planet’s biodiversity – the wide range of existence on Earth – is in the face of a historic crisis. It’s the yardstick by which we measure the health of our biodiversity. Coniferous Forest Biome – Why They Are Important. For the survival of humanity, we should learn to protect them. Although mountain regions cover only 25% of Earth’s land area, they are home to more than 85% of the world’s species of amphibians, birds, and mammals, and many of these are found only in mountains. With most of Earth's biodiversity still unidentified by science, the tree of life is far from finished. The Amazon rainforest is the most biologically diverse place on Earth. Copyright 2018 by Green and Growing. 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. At the equator sufficient rain fall, temperature, etc., favour luxuriant growth of the biodiversity. RELATED: [Coniferous Forest Biome – Why They Are Important]. Discover the most diverse countries in the world. According to experts, this is not surprising, given that hotspots represent the richest and most paramount ecosystems in the world. At the broadest most encompassing level, we have ecosystem diversity. On some tropical coral reefs, for example, there can be 1,000 species per m². Ocean acidification may render most regions of the ocean inhospitable to coral reefs, affecting tourism, food security, shoreline protection, and biodiversity. 52 Chapter 3 … 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. The Amazon rainforest is the most biologically diverse place on Earth. Our planet is a marvelous place to live on. However, due to coffee and sugar plantations, the forest was decimated to less than 0.1 million square km. With this in mind, it should come as no surprise that viruses are the most abundant biological entities on earth. What determines global patterns of biodiversity has been a puzzle for scientists since the days of von Humboldt, Darwin, and Wallace. More than 25 species in the forest are critically endangered. “Exceptions often clarify the rule and our research shows that the environmental history of a place is important to its levels of biodiversity.

Biodiversity is the name we give to the variety of all life on Earth. They host many endangered or vulnerable populations, all of them highly dependent on the environment to survive. — In the study, tropical flora was assessed across the continent. A large proportion of the world’s terrestrial biodiversity at the species level is concentrated in a small part of the world, mostly in the tropics. Credit: Colin Beale. It’s one of the longest hotspots, crawling in a narrow corridor throughout the eastern coast of Somalia, Kenya, Tanzania and Mozambique. Beautiful nature, exotic animals and a variety of orchid flowers will convince you that Colombia is one of the most extraordinary places on Earth. Nearly 4,000 endemic plant species exist here, but the hotspot is popular for the millions of colorful monarch butterflies migrating through the region each year. The study found that conservation action does work: in the first analysis of its kind, researchers found that the global biodiversity decline would have … At the equator. The biodiversity we see today is the result of 4.5 billion years of evolution and, increasingly, of human influence as well. The Polynesia-Micronesia hotspot has it all, from coastal wetlands and coral atolls to tropical rainforests and beautiful savannas. Situated in the Western Cape, this hotspot boasts the highest concentration of plant species per square kilometer in the world. Spread across Myanmar, Thailand, Cambodia, Vietnam, India and China, this biodiversity hotspot is home to 7,000 endemic plant species and numerous threatened endemic birds, mammals and amphibians. The biodiversity quiz is having multiple choice answers, participant must select the correct one either by tick it or circle it. Man-made development, pollution, and urbanization, they’re all contributing to an ever-growing effect on life. The impact of climate change may be greater on areas where stability has been the norm over extremely long time periods. 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. We can conserve most of life on Earth by protecting the most exceptional ecosystems and habitats. Like amphibians, insect species richness is greatest in tropical latitudes. However, the rainforest biome is the one with the highest species diversity. Endemic species—species that are only found in one particular location—are also found in hotspots. 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. 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 … c) 40 million.

Coral reefs are the nurseries of the oceans, they are biodiversity hot spots. “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. 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. Most plants in a biodiversity hotspot are endemic, meaning they are not found anywhere else on Earth. The hardwood trees in the rainforests that are our most effective above-ground carbon sinks are also the … Covering more than 185,427 square km of mountains, alluvial meadows, alpine grasslands, and subtropical forests. The amount of available energy or productivity is also thought to contribute to diversity, and tropical rainforests have a large amount of both. b) Scotland. The South American nation is the most biodiverse country on earth by area, and second overall behind the much larger Brazil. But the number of howler monkeys in each rainforest differs and this describes their species richness in each rainforest. Biodiversity is greater inside the world’s protected areas, scientists have been able to show for the first time. But…. 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). Some 90 other endemic bird species are currently threatened. Coincidentally, the hotspot map overlays extraordinarily on the map of the natural regions that benefit people the most. In general, diversity tends to decrease as one moves away from the equator and towards the poles. There are currently 36 recognized biodiversity hotspots.

Many different reasons are in 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. Senior author, Dr. Richard Cowling from Nelson Mandela University, added: “The extraordinary diversity of the Cape Floristic Region – as rich as the most diverse tropical forest regions – contradicts the long-held theory that high productivity is a requisite for high plant diversity. Originally boasting more than 1 million square km, the region has plummeted to just 226,000 square km in size. High numbers of endemic species of birds, amphibians and mammals live here, including a whopping 17,000 plant species. Without the many species living out there, we wouldn’t have air to breathe, water to drink, or food to eat. A common measure of this variety, called species richness, is the count of species in an area. The same hypotheses can explain tropical diversity; there is no need to invoke productivity.”. ‘Voices for Nature’ highlights initiatives and commitments for protecting the rich tapestry of life on planet earth. Stemming this crisis starts with protecting the biodiversity spots. 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:. Places … Biodiversity is the abundance and variety of life found on Earth. This is demonstrated repeatedly, across the planet, at the macro and microscopic scale. Ecuador: Yasuni - the most biodiverse place on Earth? On some tropical coral reefs, for example, there can be 1,000 species per m². You will find the answers of some questions of quiz on biodiversity is “true” or “False” type, it is specially designed to generate more awareness on biodiversity. Kirstenbosch Botanical Gardens, Rhodes Drive, Newlands, Cape Town, South Africa. Biodiversity loss, also called loss of biodiversity, a decrease in biodiversity within a species, an ecosystem, a given geographic area, or Earth as a whole. A haven of biodiversity, with more than 50,000 species of animals and plants. So… 15 Most Endangered Species on Earth Our planet, Earth, hosts more than 30 million animal species. Most of the Earth’s surface is ocean. Explanation: The equator has rich biodiversity. Coral reefs are the nurseries of the oceans, they are biodiversity hot spots. The 5 Major Threats for Biodiversity Loss. More than 2.2 million square km of the original ecosystem has already disappeared. But why might this be? Forests contain 60,000 different tree species, 80 percent of amphibian species, 75 percent of bird species, and 68 percent of the world's mammal species. This type of diversity simply looks at an area and reports what can be found there. It may sound drastic, but we wouldn’t have human societies without them. ... “I found it incredibly exciting as the first visible effects of major evolutionary events started to emerge,” Hoyal Cuthill says. 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. 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. But what are these biodiversity hotspots and where are they? Biodiversity is the primary source of Earth’s biosphere – the life web that produces everything humans need most: food, water, many modern medicines, and air. It even surpasses the plant density in the Amazon! Learn what you can do to play your part. They found that the region’s richness could be largely explained by the fact it had not experienced major changes in its climate over the past 140,000 years. 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. This is life, this is biodiversity. Conserving the species residing there will have a colossal impact in protecting the global biodiversity. 22.01.10. Researchers have discovered why the tropics and a handful of other areas across the globe have become the most biodiverse places on the planet. Species richness is the most common metric used in ecology. Q-31. Conserving the species residing there will have a colossal impact in protecting the global biodiversity. Terrestrial biodiversity is thought to be up to 25 times greater than ocean biodiversity. 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.. A new study has indicated that 31.7% of tropical African flora species are at risk of going extinct, affecting those countries that rely on its biodiversity for tourism and fuel. Kirstenbosch Botanical Gardens, Rhodes Drive, Newlands, Cape Town, South Africa. However, if we look only at terrestrial biomes, tropical rainforests have the greatest biodiversity. Amazonia represents the quintessence of biodiversity – the richest ecosystem on earth. Some researchers believe that viruses might just be the most successful of earth’s inhabitants. It forms the web of life, of which we are an integral part and upon which we so fully depend. More than 99 percent of all species that ever lived on Earth are estimated to be extinct. Although they account for just 2.3 percent of Earth’s land surface, they support over half of the world’s endemic plant species. The concept is broad and complex, but that complexity is what makes Earth a perfect place for humans to live. Habitat to 6,000 endemic plant species and numerous of bird species, the hotspot attracts eco-tourists who wish to see the Cebu flowerpecker and the Philippine eagle. As an ecosystem, the Amazon is one of the most biodiverse places on earth. 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.”. Share: FULL STORY. For example, howler monkeys can be found in the rainforests of Brazil, northern Argentina, and Bolivia. However, a number of those species are at a risk of extinction due to man’s intervention for consumption or entertainment. 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. Human interference is also minimum at this place compared to the other places of Northern Hemisphere. The country harbors between 600,000 and 700,000 different plants and animals. Changes in land-use and sea use It is important as it promotes ecosystem productivity, as well as the sustainability of life in general. The biodiversity hotspot concept first appeared in an article written by the scientist Norman Myers in 1988. Human interference is also minimum … The rivers and lagoons found within the park are home to the spectacled caiman, American crocodile and bull sharks. Origin Of The Concept. Biodiversity, also called biological diversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth. SciTechDaily: Home of the best science and technology news since 1998. 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. The equator has rich biodiversity. Costa Rica consists of only .03 of the world’s landmass, yet it consists of 5% of the earth’s biodiversity. The research set out to find an answer by focusing on the Cape Floristic Region in South Africa, a non-tropical heartland of biodiversity with around ten times as many native plant species as the UK, squeezed into an area a little smaller than Belgium. 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. Thank You. In spite of the shrinking area, researchers still discover new species, including the Annamite striped rabbit and the large-antlered muntjac. Likewise, insect species richness is immense in the Neotropics though the actual number of … Between 1999 and 2009, 1200 species of plants and vertebrates were identified for the first time. Previous scientific theories have suggested productivity – where large amounts of energy flow through an ecosystem – might explain biodiversity hotspots, but the researchers found this only played a minor role in the Cape Floristic Region’s thronging variety of life. All life on Earth hangs on biodiversity. 1. These regions have been identified as some of the world’s most important ecosystems. If provided, your email will not be published or shared. Ecosystems and species are the building blocks that sustain life on the planet, and we humans highly depend on them. They also boast almost 43 percent of endemic bird, reptile, mammal, and amphibian species. 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. The Cerrado is the name of the greatest woodland savannah in South America. So what’s the reason behind this incredible biodiversity? 22.01.10. a) China. Credit: Richard Cowling, “The results suggest that climatic variation will not affect the biodiversity of all regions evenly. However, this assertion may be Mammal extinction rate was highest in country. Ecuador: Yasuni - the most biodiverse place on Earth? The giant armadillo, giant anteater, and jaguar are amongst the mammals living in this biodiversity hotspot. Even among the larger and more mobile species, such as terrestrial vertebrates, more than one third of all species have ranges of less than 1,000 square kilometers. c) Australia. Ocean acidification may render most regions of the ocean inhospitable to coral reefs, affecting tourism, food security, shoreline protection, and biodiversity. The Cerrado is the name of the greatest woodland savannah in South America. The forked watsonia. The forests suffered due to excessive logging, reducing them to a fifth of their original size. This tremendous diversity is due to a few factors, some of which are still debated. These exist because species – both flora and fauna – do not live in the same densities around the planet. d) 59 million . Lead author, Dr. Jonathan Colville from the University of Cape Town said: “In South Africa we are fortunate to not only have incredible biodiversity, but also a uniquely detailed knowledge of where these plants are found, thanks to the collections at SANBI (South African Biodiversity Institute). Today, the Cerrado covers less than 450,000 square km, down from more than 2 million square km. Rare Star’s Giant Gamma-Ray Burst GRB 204015A Captured Close to Our Home Galaxy Earth gets blasted by mild short gamma-ray bursts (GRBs) most days. Without plants, there would be no oxygen. 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. There are only 35 such regions, called biodiversity hotspots. Sadly, 1,435 have also been classified as threatened. To understand this requires looking at the attributes that allow living organisms as well as viruses to thrive. Biodiversity underpins all life on Earth. Insects are found on land, in water and in air in nearly all habitats and all continents including Antarctica. The research suggests that biodiversity hotspots – such as the Daintree Rainforest in Australia and the Cloud Forests of Ecuador – are teeming with species because they have been ecologically stable for long periods of time, allowing evolution to forge ahead undisturbed. Biodiversity hotspots make up about 2.3 percent of Earth’s land surface, but 44 percent of the world’s plants and 35 percent of land vertebrates live in these regions. | Powered by WordPress, 10 Eco Resorts That Set the New Earth-Friendly Standard, #1: Atlantic Forest – Paraguay, Brazil, Argentina, #9: Polynesia-Micronesia, Southern Pacific Ocean. On Earth there are many biomes, and all of them have biodiversity. Biodiversity 1. Of the 9,000 different plant species, about 6,200 are endemic. All living things exist within their own communities, or ecosystems - oceans, forests, deserts, ice caps and even cities. We can’t pay Biodiversity, but it does stimulate the economy and help us get a better understanding of that thing. 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. Biodiversity hotspots are home to unique flora and fauna, most of which are endemic to the particular environment. Global biodiversity is the measure of biodiversity on planet Earth and is defined as the total variability of life forms. Clearing the land for grazing and crops for animal feed is the main activity that destroys the region. Biodiversity is not evenly distributed on Earth. 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. Some argue that a uniform climate in regards to temperature is important for biodiversity. The grasslands biomes are considered to have more biodiversity, but only grasses, wildflowers, and a few trees have adapted to its strong winds, seasonal droughts, and annual fires. Where would you expect to find more biodiversity? Places that are particularly rich in biodiversity. However, the word “Biodiversity” is relatively new, and is thought to have first been coined as a contraction of the term “biological diversity” in 1985 and then popularised by a number of authors1. 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.. Unfortunately, no less than 25 bird species became extinct in the past 200 years, due to invasive species and overhunting. These are Earth’s most biologically rich—yet threatened—terrestrial regions. Bacteria to baboons, plants to people - the range of life on our planet is incredible. Biodiversity found on Earth today consists of many millions of distinct biological species, the product of four billion years of evolution. The diversity of plants and animals in Earth's arctic regions is moderate. At the equator sufficient rain fall, temperature, etc., favour luxuriant growth of the biodiversity. The loss and degradation of biodiversity negatively affects every level of the planet. All of the Earth’s species work together to survive and maintain their ecosystems.
