why is species diversity important

Genetic diversity, which refers to genetic variation within and between populations, has a big role, too. A species’ future potential for adaptation depends on the genetic diversity held in the genomes of the individuals in populations that make up the species. It will not be able to maintain in the face of stressors like disease or compromised air or water quality and it will face imminent extinction. For example in the figure below, Alpha Diversity of Site A = 7 species, Site B = 5 species, Site C = 7 species. More diverse ecosystem tend to be more productive. For crops and domestic animals, diversity within species is at least as important as diversity between species and has been greatly expanded through agriculture. However, species richness increases with sample size. Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. A.6. So to make a more efficient, productive and sustainable ecosystem, it is important to maintain high species diversity. The animal classification system characterizes animals based on their anatomy, morphology, evolutionary history, features of embryological development, and genetic makeup. The more equal species are in proportion to each other, the greater the evenness of the site. The largest study of this kind investigated the diversity of unique functional traits represented by rare species in coral reef fishes, alpine plants, and tropical trees. High species diversity is important for the processes and functions of all ecosystems, whether terrestrial or marine, mountain top or deep sea trench. People, including the sum of their selves, knowledge, and experience, are the raw ingredients for our businesses. According to the Encyclopedia of Earth, species diversity is a measurement of an ecosystem’s species richness and species evenness. Beta Diversity = expression of diversity between habitats. Biodiversity, or biological diversity, is the incredible variety of life on Earth. With between 3 and 30 million species on earth, here are the reasons why they are important. Biodiversity is categorized into species diversity, genetic diversity and ecosystem diversity. Yes, for evolution it is because it creates evolved species that can survive with the climate and Earth changes but also diversity is important because it brings new knowledge, new behaviour, and … A keystone species is an organism that helps maintain species diversity within an ecosystem by keeping the numbers of other species in an ecosystem constant. Environments that can support large numbers of species, such as tropical areas, tend to have greater species richness. It depicts heterogeneity that persists in nature. A diverse species assemblage also contributes to ecosystem diversity. I understand why ecologists want to preserve species that serve a vital part in the ecosystem. biodiversity. It is important for species to have diversity in order to maintain resilience against unanticipated events, For example, natural disasters such as earthquakes, tsunamis, volcanic eruptions and more. Essentially, by having greater genetic diversity within a fish species (e.g., many discrete populations with different life history strategies rather than a single homogenized population), the species is more apt to withstand variable conditions. Prof. E. O Wilson, in How Our Health Depends on Biodiversity, Chivian, E., Bernstein A., Center for Health and the Global Environment, Harvard Medical School, 2010 . Species evenness is a measure of the relative abundance of the different species making up the richness of an area. More From Reference. Because of the availability of different species, humans are able to obtain a range of materials and foods used to support their well-being and health. The more even the number of animals per species within an ecosystem, the greater the species diversity. Species diversity depends as much on the genetic diversity as on the environmental condition. Created by. The Encyclopedia of Earth defines species evenness as “the variation in the abundance of individuals per species within a community.” If a community has a large disparity between the number of individuals within each species it has low evenness. Tree selection based on size is also important. For example, as genetic diversity of the main tree species is lost, other species, like insects and fungi, that are specifically associated with certain trees may disappear too, leaving the whole forest ecosystem biologically impoverished. Robert Balun has been writing both creatively and academically for more than eight years. Diversity is important because first and foremost, it helps buffer environmental stresses on an ecosystem. They must identify traits that are common to all animals as well as traits that can be used to distinguish among related groups of animals. For example in the figure below, Alpha Diversity of Site A = 7 species, Site B = 5 species, Site C = 7 species. By not allowing one species or another to become overly dominant, a keystone species maintains species diversity and ecosystem integrity. If community B has ten individuals divided between two species, with species 1 having four individuals and species 2 having six, then community B has high evenness and higher species diversity. the ecosystem with a great variety of producer species will produce large biomass to support a greater variety of consumer species 2. Understanding and classifying the great variety of living species help us better understand how to conserve the diversity of life on earth. If community A has 10 individuals divided between two species, but species 1 represents nine individuals, while species 2 has only one, then community A has a low evenness and lower species diversity. In disease resistance, genetic diversity is important because a disease can decimate a homogeneous population in which all the individuals are equally susceptible to the disease. More specifically, genetic diversity can be a species natural defense system against disease and survival even under extreme weather conditions but more importantly, genetic diversity can help weed out unfavorable traits in species which maximizes opportunities for thriving in any environment . If an invasive species forces out too many other species, the species diversity will drop, which could cause an ecosystem to function inefficiently or fail. Match. Do they include ash or maple?
