Island Biodiversity - Why is it Important? In order to discuss why living organisms are so diverse it is firstly important to discuss what diversity actually is. This will help you in acing your NEET exam effectively. Save. by noeli870_26447. Genetic diversity is important because it helps maintain the health of a population, by including alleles that may be valuable in resisting diseases, pests and other stresses. This encompasses race, ethnicity, gender, age, sexual orientation, physical … The natural disaster prevention mechanisms in most ecosystems and other free services we all get from the surrounding environment are not easily replaceable or replicable, so maintaining biodiversity is important. Biology. As the preeminent scientist Theodosius Dobzhansky stated, “Nothing in biology makes sense except in the light of evolution.” Evolution is the only scientific explanation for the diversity of life. The Convention on Biological Diversity includes variation between species (species diversity), within a species (genetic diversity) and between ecosystems (ecosystem diversity) within their definition. This diversity occurs at three levels: genetic, species, and ecosystem. What is Species Diversity? Why does biodiversity consist of several parts: genetic diversity, species diversity and ecosystem diversity? Diversity refers to the variety of differences between individuals. Species diversity in a forest ecosystem depends on the genetic diversity of key tree species. Without biodiversity, the health of the planet is at stake. Many islanders are endowed with unique cultures and derive much of their economic, environmental and cultural well-being directly or indirectly from the rich natural resources in their immediate environment. Also Read: Biodiversity in Plants and Animals. Biodiversity and its maintenance are very important for sustaining life on earth. Understanding why some species are more abundant than others is particularly important because communities that are strongly dominated by one or a few species often have low species diversity overall. Biodiversity or biological diversity is a term that describes the variety of living beings on earth. Species diversity is a measure that combines the number of species in a community with the relative abundances of those species. Biological diversity is one of the most important values of the Earth. ADVERTISEMENTS: Microbes are one of the dominant life forms which occur in the universe, but most of us are ignorant of their true profile. Biodiversity loss can impact on community traditions and livelihoods centred on traditional medicinal practices that utilise wild animals and plants, particularly for indigenous and local communities. Millions of people depend upon Genetic diversity within a population is the variety of different alleles (versions) of genes present, which lead to a variety of phenotypes. Biodiversity can be defined broadly as the variety of life of Earth. Biology - species diversity; How do you measure the diversity of species? 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. Understanding evolution is critical for understanding biology. It is important for a number of reasons, such preventing inbreeding and allowing the population to more adaptable to changing environments. Chemical diversity is one way to measure diversity that is important to human health and welfare. 1 Answer Linica Uday Apr 10, 2017 Species evenness is a measure of the relative abundance of the different species making up the richness of an area. Biology is subdivided into separate branches for convenience of study, though all the subdivisions are interrelated by basic principles. Why Biology? Biodiversity is the total variation between all living things and can be measured to help identify species that need to be supported. Biodiversity, short for biological diversity, is the term we use for the variety of animals, plants, fungi, bacteria, and other intertwined life forms within any ecosystem… “from towering redwood trees to tiny, single-cell algae that are impossible to see without a microscope.”.
