where is the most biodiversity found on earth

Global biodiversity is the measure of biodiversity on planet Earth and is defined as the total variability of life forms. With this in mind, it should come as no surprise that viruses are the most abundant biological entities on earth. So… So… The loss and degradation of biodiversity negatively affects every level of the planet. 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. It’s the yardstick by which we measure the health of our biodiversity. Researchers have discovered why the tropics and a handful of other areas across the globe have become the most biodiverse places on the planet. Learn what you can do to play your part. 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. Biodiversity is greater inside the world’s protected areas, scientists have been able to show for the first time. 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. Some argue that a uniform climate in regards to temperature is important for biodiversity. Our planet’s biodiversity – the wide range of existence on Earth – is in the face of a historic crisis. Share: FULL STORY. The forked watsonia. But what are these biodiversity hotspots and where are they? Ranging from a coin sized pnk rigned frog to a 4 meter long anaconda, the findings confirm the Amazon as one the most biodiverse places on Earth… Forests harbour most of Earth's terrestrial biodiversity. Sadly, 1,435 have also been classified as threatened. Proteas in Kirstenbosch Botanic Gardens with natural vegetation on Table Mountain behind. A common measure of this variety, called species richness, is the count of species in an area. Situated in the Western Cape, this hotspot boasts the highest concentration of plant species per square kilometer in the world. 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. Ocean acidification may render most regions of the ocean inhospitable to coral reefs, affecting tourism, food security, shoreline protection, and biodiversity. The forests suffered due to excessive logging, reducing them to a fifth of their original size. Man-made development, pollution, and urbanization, they’re all contributing to an ever-growing effect on life. Most plants in a biodiversity hotspot are endemic, meaning they are not found anywhere else on Earth. However, there are places that are severely threatened in spite of being some of the most biologically rich corners on Earth. The UK government is facing criticism for a lack of progress in hitting major biodiversity targets. So what’s the reason behind this incredible biodiversity? The rate of extinction of species has never being higher – except for the legendary mass extinction of the dinosaurs. b) Scotland. The impact of climate change may be greater on areas where stability has been the norm over extremely long time periods. 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. a) China. The rivers and lagoons found within the park are home to the spectacled caiman, American crocodile and bull sharks. Most of the Earth’s surface is ocean. 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. Two of the Most Diverse Ecosystems on Earth Species richness is greatest in tropical ecosystems. It forms the web of life, of which we are an integral part and upon which we so fully depend. What determines global patterns of biodiversity has been a puzzle for scientists since the days of von Humboldt, Darwin, and Wallace. Australia is an interesting case of mega-biodiversity as it is one of two developed countries in the list. 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). Covering more than 185,427 square km of mountains, alluvial meadows, alpine grasslands, and subtropical forests. On some tropical coral reefs, for example, there can be 1,000 species per m². Earth’s Biodiversity Bursts Do Not Follow Expected Pattern. While other planets are likely rich in minerals of high monetary value here on Earth, no other planet that we know of have the conditions necessary for human civilization. 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 equator has rich biodiversity. 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. All of these species were found only in Lake Victoria; therefore, the 500 species of cichlids were endemic. 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. While biomes with low biodiversity tend to be inhospitable to most life, the biome with the highest biodiversity is inhospitable to most human settlement. In fact, tropical rainforests support the greatest biodiversity on Earth. More than 99 percent of all species that ever lived on Earth are estimated to be extinct. Today, the Cerrado covers less than 450,000 square km, down from more than 2 million square km. Biodiversity, also called biological diversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth. For example, the grass in pastures feeds cattle. Biodiversity, also called biological diversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth. The biodiversity we see today is the result of 4.5 billion years of evolution and, increasingly, of human influence as well. — In the study, tropical flora was assessed across the continent. The same hypotheses can explain tropical diversity; there is no need to invoke productivity.”. The hardwood trees in the rainforests that are our most effective above-ground carbon sinks are also the … Mammal extinction rate was highest in country. The word biodiversity is a contraction of 'biological diversity'. 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. These are Earth’s most biologically rich—yet threatened—terrestrial regions. Credit: Richard Cowling, “The results suggest that climatic variation will not affect the biodiversity of all regions evenly. a) 3.5 billion . Conserving the species residing there will have a colossal impact in protecting the global biodiversity. 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. 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. 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. The giant armadillo, giant anteater, and jaguar are amongst the mammals living in this biodiversity hotspot. The South American nation is the most biodiverse country on earth by area, and second overall behind the much larger Brazil. The country harbors between 600,000 and 700,000 different plants and animals. Places with unique animals and plants. Endangered species are found throughout the world. Biodiversity is the abundance and variety of life found on Earth. Some 90 other endemic bird species are currently threatened. d) 59 million . Biodiversity hotspots are home to unique flora and fauna, most of which are endemic to the particular environment. With most of Earth's biodiversity still unidentified by science, the tree of life is far from finished. “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. Columbia Research Shows How Energy Could Be Extracted, Humans Face a “Ghastly Future” Unless Extraordinary Action Is Taken Soon on Sustainability, New Research Finds Colleges Can Prevent 96% of COVID-19 Infections Without Vaccines, Stunning Martian Panorama Celebrates NASA’s Curiosity Rover’s 3,000th Day on Mars, Pioneering Research Reveals How Teeth Functioned and Evolved in Giant Mega-Sharks, Upper Ocean Temperatures Hit Record High in 2020 – Poses “A Severe Risk to Human and Natural Systems”, Harvard-Smithsonian Center for Astrophysics. Of all the known species in the world, 10% are in the Amazon rainforest. A common measure of this variety, called species richness, is the count of species in an area. Habitat loss and human activities, in general, have posed a high risk on these green spots. Of all the known species in the world, 10% are in the Amazon rainforest.
