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). 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:. High numbers of endemic species of birds, amphibians and mammals live here, including a whopping 17,000 plant species. All living things exist within their own communities, or ecosystems - oceans, forests, deserts, ice caps and even cities. While biomes with low biodiversity tend to be inhospitable to most life, the biome with the highest biodiversity is inhospitable to most human settlement. 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 same hypotheses can explain tropical diversity; there is no need to invoke productivity.”. The Cerrado is the name of the greatest woodland savannah in South America. Biodiversity is the amazing variety of life on Earth. To understand this requires looking at the attributes that allow living organisms as well as viruses to thrive. 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. It forms the web of life, of which we are an integral part and upon which we so fully depend. 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. If provided, your email will not be published or shared. Today, the Cerrado covers less than 450,000 square km, down from more than 2 million square km. | 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. 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… On Earth there are many biomes, and all of them have biodiversity.

Ocean acidification may render most regions of the ocean inhospitable to coral reefs, affecting tourism, food security, shoreline protection, and biodiversity. The South American nation is the most biodiverse country on earth by area, and second overall behind the much larger Brazil. b) Scotland. Learn what you can do to play your part. Ecologists have long sought to understand why some areas of the planet are extraordinarily rich in species. Email address is optional. The biodiversity quiz is having multiple choice answers, participant must select the correct one either by tick it or circle it. In spite of the shrinking area, researchers still discover new species, including the Annamite striped rabbit and the large-antlered muntjac. Two of the Most Diverse Ecosystems on Earth Species richness is greatest in tropical ecosystems. Earth’s Biodiversity Bursts Do Not Follow Expected Pattern Life’s great radiations do not always line up with mass extinctions, a new study shows By Riley Black on January 14, 2021 Ecosystems and species are the building blocks that sustain life on the planet, and we humans highly depend on them. So what can we do about it? Amazing discoveries: 1200 new species found in the Amazon. Of the 9,000 different plant species, about 6,200 are endemic. Let’s start with biodiversity. Man-made development, pollution, and urbanization, they’re all contributing to an ever-growing effect on life. Researchers have discovered why the tropics and a handful of other areas across the globe have become the most biodiverse places on the planet. Tropical rainforests are found right around the equator. At the equator sufficient rain fall, temperature, etc., favour luxuriant growth of the biodiversity. Australia is an interesting case of mega-biodiversity as it is one of two developed countries in the list. However, this assertion may be There are only 35 such regions, called biodiversity hotspots. Most plants in a biodiversity hotspot are endemic, meaning they are not found anywhere else on Earth. 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. For a region to qualify as a biodiversity hotspot, it must meet the two following criteria: Only 35 areas around the globe qualify as hotspots. Thank You. Biodiversity is not evenly distributed on Earth. 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. Some researchers believe that viruses might just be the most successful of earth’s inhabitants. The uneven distribution means that certain regions boasts unbelievable numbers of endemic species. The biodiversity we see today is the result of 4.5 billion years of evolution and, increasingly, of human influence as well. 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. 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. 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. — In the study, tropical flora was assessed across the continent. Credit: Colin Beale. Copyright © 1998 - 2021 SciTechDaily. A highland area, this hotspot initially covered more than 461,000 square km across Mexico and southern U.S. 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. However, a number of those species are at a risk of extinction due to man’s intervention for consumption or entertainment. It upholds some 4,400 endemic plant species, as well as some of the most fascinating animal species. It is important as it promotes ecosystem productivity, as well as the sustainability of life in general. 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. However, if we look only at terrestrial biomes, tropical rainforests have the greatest biodiversity. 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.”. Although they cover a small area - less than 2% of Earth's surface - rainforests are home to about half the life on Earth. The staggering fact is that one in every 10 species of flora and fauna that is found on earthcan be found in Colombia. This is demonstrated repeatedly, across the planet, at the macro and microscopic scale. Mammal extinction rate was highest in country. 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. 1. 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. The impact of climate change may be greater on areas where stability has been the norm over extremely long time periods. c) 40 million. Earth’s biodiversity is the very basis for our own survival. found in a particular location and nowhere else; fully 25% of Hawaiian coral species are endemic to the area (Pacific Whale Foundation 2003). Copyright 2018 by Green and Growing. But the most species aren’t described yet. Places with unique animals and plants.

Caribbean Islands Hotspot- This Island Hotspot comprises of 30 nations and territories as Anguilla, Bermuda, British Virgi… Endangered species are found throughout the world. The UK government is facing criticism for a lack of progress in hitting major biodiversity targets. The giant armadillo, giant anteater, and jaguar are amongst the mammals living in this biodiversity hotspot. The rate of extinction of species has never being higher – except for the legendary mass extinction of the dinosaurs. Ecuador: Yasuni - the most biodiverse place on Earth? The Philippines hotspot is one of the richest regions in biodiversity, including more than 7,100 islands in the Pacific Ocean. This is true not just for people, but for all life forms on earth. Biodiversity 1. The findings were published in the Science Advances Journal and used an assessment process […] But…. The rivers and lagoons found within the park are home to the spectacled caiman, American crocodile and bull sharks. In general, diversity tends to decrease as one moves away from the equator and towards the poles. For example, howler monkeys can be found in the rainforests of Brazil, northern Argentina, and Bolivia. This tremendous diversity is due to a few factors, some of which are still debated. Areas with extremely high levels of biodiversity are called hotspots. 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. The Polynesia-Micronesia hotspot has it all, from coastal wetlands and coral atolls to tropical rainforests and beautiful savannas. 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. In fact, tropical rainforests support the greatest biodiversity on Earth. 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. 15 Most Endangered Species on Earth Our planet, Earth, hosts more than 30 million animal species. 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. Endemic species—species that are only found in one particular location—are also found in hotspots. Costa Rica consists of only .03 of the world’s landmass, yet it consists of 5% of the earth’s biodiversity. This type of diversity simply looks at an area and reports what can be found there. However, due to coffee and sugar plantations, the forest was decimated to less than 0.1 million square km. Biodiversity underpins all life on Earth. 22.01.10. Discover the most diverse countries in the world. Our planet is a marvelous place to live on. Kirstenbosch Botanical Gardens, Rhodes Drive, Newlands, Cape Town, South Africa.
