The country harbors between 600,000 and 700,000 different plants and animals. On some tropical coral reefs, for example, there can be 1,000 species per m². Researchers have discovered why the tropics and a handful of other areas across the globe have become the most biodiverse places on the planet. 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. 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. There are only 35 such regions, called biodiversity hotspots. Australia is an interesting case of mega-biodiversity as it is one of two developed countries in the list. Although they account for just 2.3 percent of Earth’s land surface, they support over half of the world’s endemic plant species. c) 40 million. Copyright 2018 by Green and Growing. This is demonstrated repeatedly, across the planet, at the macro and microscopic scale. Biodiversity underpins all life on Earth. But marine life accounts for only 15 percent of the world’s species. 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. At the equator. 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… Stemming this crisis starts with protecting the biodiversity 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. 52 Chapter 3 … However, a number of those species are at a risk of extinction due to man’s intervention for consumption or entertainment. The biodiversity hotspot concept first appeared in an article written by the scientist Norman Myers in 1988. At the broadest most encompassing level, we have ecosystem diversity. Places … Researchers have discovered why the tropics and a handful of other areas across the globe have become the most biodiverse places on the planet. 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. 15 Most Endangered Species on Earth Our planet, Earth, hosts more than 30 million animal species. Amazing discoveries: 1200 new species found in the Amazon. The Cerrado is the name of the greatest woodland savannah in South America. The Amazon rainforest is the most biologically diverse place on Earth. For example, howler monkeys can be found in the rainforests of Brazil, northern Argentina, and Bolivia. The Mesoamerican forests – extending over Mexico, Guatemala, Belize, Honduras, El Salvedor, Nicaragua, Costa Rica, and Panama – amass a stunning collection of sub-tropical and tropical ecosystems. 22.01.10. 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.. At the equator sufficient rain fall, temperature, etc., favour luxuriant growth of the biodiversity. Places with unique animals and plants. d) 59 million . So what’s the reason behind this incredible biodiversity? | 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. 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. However, due to coffee and sugar plantations, the forest was decimated to less than 0.1 million square km. a) China. But the most species aren’t described yet.

According to experts, this is not surprising, given that hotspots represent the richest and most paramount ecosystems in the world. Biological diversity—or biodiversity—is the variety of life on Earth and the natural patterns it forms. Our planet’s biodiversity – the wide range of existence on Earth – is in the face of a historic crisis. “Exceptions often clarify the rule and our research shows that the environmental history of a place is important to its levels of biodiversity. Cattle then produce manure that returns nutrients to the soil, which helps to … Although they cover a small area - less than 2% of Earth's surface - rainforests are home to about half the life on Earth. In some environments, virus particles exceed cell numbers by one to two orders of magnitude. We can’t pay Biodiversity, but it does stimulate the economy and help us get a better understanding of that thing. d) Bahammas. Credit: Richard Cowling, “The results suggest that climatic variation will not affect the biodiversity of all regions evenly. Coincidentally, the hotspot map overlays extraordinarily on the map of the natural regions that benefit people the most. Mountain regions—especially those in the tropics—are hotspots of extraordinary and baffling biodiversity, according to new research. ... “I found it incredibly exciting as the first visible effects of major evolutionary events started to emerge,” Hoyal Cuthill says. Without plants, there would be no oxygen. The hardwood trees in the rainforests that are our most effective above-ground carbon sinks are also the … Ocean acidification may render most regions of the ocean inhospitable to coral reefs, affecting tourism, food security, shoreline protection, and biodiversity. They also boast almost 43 percent of endemic bird, reptile, mammal, and amphibian species. Like amphibians, insect species richness is greatest in tropical latitudes. The Himalaya hotspot may just be the most widespread of them all, covering China, Nepal, Bhutan, Pakistan, Bangladesh, and Myanmar. 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. There would be no human society at all. However, the rainforest biome is the one with the highest species diversity. Coniferous Forest Biome – Why They Are Important. 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. Coral reefs are the nurseries of the oceans, they are biodiversity hot spots. Credit: Colin Beale. 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. 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. The UK government is facing criticism for a lack of progress in hitting major biodiversity targets. 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. 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. However, if we look only at terrestrial biomes, tropical rainforests have the greatest biodiversity. Share: FULL STORY. 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. 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. So… Discover the most diverse countries in the world. Biodiversity, also called biological diversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth. On Earth there are many biomes, and all of them have biodiversity. The same hypotheses can explain tropical diversity; there is no need to invoke productivity.”. c) Australia. 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. More than 99 percent of all species that ever lived on Earth are estimated to be extinct. But the number of howler monkeys in each rainforest differs and this describes their species richness in each rainforest. Between 1999 and 2009, 1200 species of plants and vertebrates were identified for the first time. Many different reasons are in Q-30. “This rich resource enabled us to pull together an interdisciplinary team from South Africa and the UK to tackle one of the most challenging questions in ecology and highlights how important international collaborations are to the future success of South African research and the conservation of its biodiversity.”, Reference: “Plant richness, turnover, and evolutionary diversity track gradients of stability and ecological opportunity in a megadiversity center” by Jonathan F. Colville, Colin M. Beale, Félix Forest, Res Altwegg, Brian Huntley and Richard M. Cowling, 5 August 2020, Proceedings of the National Academy of Sciences. RELATED: [10 Eco Resorts That Set the New Earth-Friendly Standard]. High numbers of endemic species of birds, amphibians and mammals live here, including a whopping 17,000 plant species. Earth’s Biodiversity Bursts Do Not Follow Expected Pattern. Beautiful nature, exotic animals and a variety of orchid flowers will convince you that Colombia is one of the most extraordinary places on Earth. The rate of extinction of species has never being higher – except for the legendary mass extinction of the dinosaurs. Some argue that a uniform climate in regards to temperature is important for biodiversity. Life began there. So… As an ecosystem, the Amazon is one of the most biodiverse places on earth. Where would you expect to find more biodiversity? Tropical rainforests are found right around the equator. Australia is 1st in the world for endemics. 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. -  Designed by Thrive Themes 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. SciTechDaily: Home of the best science and technology news since 1998. California Floristic Province- It lies in the region that extends from Santa Barbara in Southern California to the parallel 30th in Northern Baja California (about 220 miles from San Diego) 2. But…. It is virtually synonymous with “Life on earth”. 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. It is important as it promotes ecosystem productivity, as well as the sustainability of life in general. 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. Earth’s biodiversity is the very basis for our own survival. Human interference is also minimum … 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. Proteas in Kirstenbosch Botanic Gardens with natural vegetation on Table Mountain behind. 1. Ecologists have long sought to understand why some areas of the planet are extraordinarily rich in species. The loss and degradation of biodiversity negatively affects every level of the planet.

On some tropical coral reefs, for example, there can be 1,000 species per m². This is life, this is biodiversity. This website uses cookies to ensure you get the best experience on our website. The Cerrado is the name of the greatest woodland savannah in South America. Insects are found on land, in water and in air in nearly all habitats and all continents including Antarctica. It upholds some 4,400 endemic plant species, as well as some of the most fascinating animal species. 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). Thank You. Lake Victoria contained almost 500 species of cichlids alone, ignoring the other fish families present in the lake. Biodiversity also describes ecosystems or environments that contain a high degree of this variation — for example, the Amazon rainforest. So what can we do about it? It even surpasses the plant density in the Amazon! Explanation: The equator has rich biodiversity. Today, the Cerrado covers less than 450,000 square km, down from more than 2 million square km. 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.”. 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.. These exist because species – both flora and fauna – do not live in the same densities around the planet. With this in mind, it should come as no surprise that viruses are the most abundant biological entities on earth. To understand this requires looking at the attributes that allow living organisms as well as viruses to thrive. This biodiversity hotspot originally covered about 1.2 million square km. 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. These are Earth’s most biologically rich—yet threatened—terrestrial regions. 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. Below is the most bio-diverse country. Biodiversity found on Earth today consists of many millions of distinct biological species, the product of four billion years of evolution. A common measure of this variety, called species richness, is the count of species in an area. At the equator sufficient rain fall, temperature, etc., favour luxuriant growth of the biodiversity. 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. Clearing the land for grazing and crops for animal feed is the main activity that destroys the region. And as the places on Earth where the most biodiversity is under the most threat, hotspots are critical to human survival. Let’s start with biodiversity. Most plants in a biodiversity hotspot are endemic, meaning they are not found anywhere else on Earth. In general, diversity tends to decrease as one moves away from the equator and towards the poles. There are only 35 such regions, called biodiversity hotspots. The equator has rich biodiversity. Without the many species living out there, we wouldn’t have air to breathe, water to drink, or food to eat. The giant armadillo, giant anteater, and jaguar are amongst the mammals living in this biodiversity hotspot. A highland area, this hotspot initially covered more than 461,000 square km across Mexico and southern U.S. Other benefits of biodiversity are even more fundamental. It may sound drastic, but we wouldn’t have human societies without them. There are more than 378 species of mammals, 828 species of birds, 300 different lizards, 140 species of snakes, etc. 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.
