  1. Biodiversity

    Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (genetic variability), species (species diversity), and ecosystem (ecosystem diversity) level.Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural processes that sustain life. Rapid environmental changes typically cause mass extinctions. More than 99.9% of all species that ever lived on Earth, amounting to over five billion species, are estimated to be extinct. Estimates on the number of Earth's current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86% have not yet been described. The total amount of related DNA base pairs on Earth is estimated at 5.0 x 1037 and weighs 50 billion Tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as four trillion tons of carbon. In July 2016, scientists reported identifying a set of 355 genes from the last universal common ancestor (LUCA) of all organisms living on Earth. The age of the Earth is about 4.54 billion years. The earliest undisputed evidence of life dates at least from 3.7 billion years ago, during the Eoarchean era after a geological crust started to solidify following the earlier molten Hadean eon. There are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia. Other early physical evidence of a biogenic substance is graphite in 3.7 billion-year-old meta-sedimentary rocks discovered in Western Greenland. More recently, in 2015, "remains of biotic life" were found in 4.1 billion-year-old rocks in Western Australia. According to one of the researchers, "If life arose relatively quickly on Earth...then it could be common in the universe."Since life began on Earth, five major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic aeon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosion—a period during which the majority of multicellular phyla first appeared. The next 400 million years included repeated, massive biodiversity losses classified as mass extinction events. In the Carboniferous, rainforest collapse led to a great loss of plant and animal life. The Permian–Triassic extinction event, 251 million years ago, was the worst; vertebrate recovery took 30 million years. The most recent, the Cretaceous–Paleogene extinction event, occurred 65 million years ago and has often attracted more attention than others because it resulted in the extinction of the non-avian dinosaurs. The period since the emergence of humans has displayed an ongoing biodiversity reduction and an accompanying loss of genetic diversity named the Holocene extinction, and often referred to as the sixth mass extinction. The reduction is caused primarily by human impacts, particularly habitat destruction. Conversely, biodiversity positively impacts human health in many ways, although a few negative effects are studied.

  1. biodiversity

    Biodiversity refers to the variety and variability of life on Earth. It includes the variety of all forms of life, including different plants, animals, microorganisms, the genetic information they contain and the ecosystems they form. It is typically measured in terms of the richness, evenness, or abundance of species and ecosystems present in a particular area. Biodiversity supports multiple ecosystem functions and services, including food and water supply, pollination of plants, control of pests and diseases, and regulation of climate.

  1. Biodiversity

    Biodiversity is the degree of variation of life forms within a given species, ecosystem, biome, or planet. Terrestrial biodiversity tends to be highest at low latitudes near the equator, which seems to be the result of the warm climate and high primary productivity. Marine biodiversity tends to be highest along coasts in the Western Pacific, where sea surface temperature is highest and in mid-latitudinal band in all oceans. Biodiversity generally tends to cluster in hotspots, and has been increasing through time but will be likely to slow in the future. Rapid environmental changes typically cause mass extinctions.

Examples of biodiversity in a Sentence

  1. Extinction Rebellion:

    We are watching, in real-time, as people's lives are destroyed around the world and in the UK; unless action is taken to halt biodiversity loss and reduce greenhouse gas emissions to net zero, these tragedies are set to worsen.

  2. Joseph Wilson:

    I heard a commissioner say that only 10 % of the land at Grand-Staircase has any scenic value, to them 90 % of this was worthless, but that underestimates the importance of biodiversity here and we can assume that things that cause a lot of disturbance to the area will have negative consequences.

  3. Tierra Curry:

    Climate change threatens life on Earth, we have to fight climate change and biodiversity loss at the same time. Climate changes gets a lot more attention than extinction, but extinction is a big problem.

  4. Frederick Hubbard:

    Now, the question is, what do we need to do to get them to recover ? said Dr. Frank Ridgleyhead of conservation and research at Zoo Miami. Biologists believe they have the answer. Executives of the Patch of Heaven Sanctuary, a nonprofit organization dedicated to creating habitats for wildlife, in February finished building what they claim is the largest bat house in the world in an effort to save Floridas high flyers. Nobody else is doing this kind of work. Not on this scale, said Frederick Hubbard, the sanctuarys executive director. The two-tier structure can house up to 250,000 bats. The University of Florida boasts large bat houses of The University of Florida own.According to the [ UF ] web site, theyre the biggest occupied bat houses in the world, Frederick Hubbard told the Miami Herald. Our bat house is technically bigger. Were trying to get the wording right on that. Frederick Hubbard says the batstend to form colonies, living together and procreating. The new two-tier bat house can hold up to 250,000 total bats. ( Elina Shirazi/Fox News) Theres usually a dominant male, a large male who establishes and claims these coveted kinds of spaces and then he tries to attract females and the females tend to then be attracted to a male who is going to defend the territory and keep a safe space for them, Ridgley said. CLICK HERE TO GET THE FOX NEWS APP Ridgley says the bats are vital to biodiversity and in fact helpful to humans. Theyre cleaning up our skies. Theyre providing all these services and in some parts of the country, you know, bats literally provide billions of dollars of services to the residents, Ridgley said. Ridgley said its hard to know the history of the bats since they were only discovered as a unique species in 2004. There was very little known about this bat just about a decade ago. I mean they only knew of one place where they were roosting and it was a mystery across their whole range here in South Florida. Anything about them, you know, what kind of groups they had, what they need to survive. So there was a lot of intensive study going into answering some of these questions, said Ridgley. Ridgley estimates their population is now only in the hundreds, and technology is helping them to keep track. One device they use, an echo meter, plugs into a cell phone and identifies the type of bat and itslocation based off of sound. They do a type of echolocation and supposedly they have some recorded sounds that theyre going to be able to put up into the bat-house that will attract them, said Frederick Hubbard. Creators claim this bat house at the Patch of Heaven Sanctuary is the largest in the world. Frederick Hubbard said that if their project accomplishes its aim, it may help rewrite the fate of these bats who have lost almost all of their habitat. For now, Frederick Hubbard said they are patiently waiting for the bats to rent out their space. Come home.

  5. Luiz Rocha:

    Though the species is quite abundant and therefore not currently at a high risk of overexploitation, it's still unsettling when a fish is already being commercialized before it even has a scientific name, it speaks to how much biodiversity there is still left to be described from coral reef ecosystems.
