Biodiversity - 626 Words

Biodiversity a.Biodiversity- is the degree of variation of life. It is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation, ecosystem variation, or species variation (number of species) within an area, biome, or planet. Terrestrial biodiversity tends to be highest near the equator, which seems to be the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth. It is the richest in the tropics. Marine biodiversity tends to be highest 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†¦show more content†¦As ecosystems are defined by the network of interactions among organisms, and between organisms and their environment, they can be of any size but usually encompass specific, limited spaces. f. species diversity- is the number of di fferent species that are represented in a given community (a dataset). The effective number of species refers to the number of equally abundant species needed to obtain the same mean proportional species abundance as that observed in the dataset of interest (where all species may not be equally abundant). Species diversity consists of two components: species richness and species evenness. Species richness is a simple count of species, whereas species evenness quantifies how equal the abundances of the species are. g. species richness-is the number of different species represented in an ecological community, landscape or region. Species richness is simply a count of species, and it does not take into account the abundances of the species or their relative abundance distributions. 2. Differentiate the following Genetic diversity | Community diversity | Landscape diversity | level of biodiversity, refers to the total number of genetic characteristics in the genetic makeup of a species. It is distinguished from genetic variability, which describes the tendency of genetic characteristics to vary. | An ecosystem is a higher level of community.

Biodiversity can be studied on a global level all the way down to studying it within a microscopic ecosystem (National Wildlife Federation, 2015). It is important to understand that biodiversity can be looked at genetically as well as environmentally as well. For example, genetic biodiversity is seen in the variation of different breeds within the dog species, while environmental biodiversityRead MoreBiodiver sity And Its Effects On Biodiversity1691 Words   |  7 PagesAbstract. Biodiversity is a variety of life and it is important to maintain biodiversity because it provides everyone’s needs for food source, water source and shelter. Currently, Georgia Gwinnett College expanding with construction around the area, will this cause a disturbance where the campus will not be able to have biodiversity or having some disturbance can increase it? The research measured biodiversity in 5 different places around campus, these locations varying levels of disturbance andRead MoreEconomics to Biodiversity989 Words   |  4 Pagesi. Biodiversity First Even if many conservation organisations and many others have been engaged in the environmental protection, yet there is a divide about how people look at it and are ready to get engaged in such activities. Environmental education should -create awareness, -transmit information, -teach knowledge, -develop habits and skills, -promote values, and provide criteria and standards and present guidelines for problem solving and decision-making. This needs classroom as well fieldRead MoreThe Study of Biodiversity939 Words   |  4 PagesBiodiversity – the amount of living things; animals, microorganisms and plants. It also includes the genetic information these living things contain, and the ecosystems and biomes they form. 3 ways biodiversity can be studied: - GENETIC DIVERSITY: The amount of different genetic characteristics of the species in their genetic make up. - SPEICIES DIVERSITY: the amount of species in a particular area in the world. - ECOSYSTEM DIVERSITY: the amount of ecosystems in a given region or biome. - PlacesRead MoreThe Importance of Biodiversity1521 Words   |  7 Pages‘Define Biodiversity and using examples, explain why it is important’ Biodiversity is the variety of life on earth. A fuller definition is given in the Convention on Biological Diversity (CBD) from the 1992 Earth summit: ‘Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part ; this includes diversity within species, between species and of ecosystems’ (Hambler, C., 2004Read MoreBiodiversity. Biodiversity Is The Variability Among Living1684 Words   |  7 PagesBiodiversity Biodiversity is the variability among living organisms from all sources including terrestrial, marine and other aquatic ecosystems. This includes diversity within species, between species, and ecosystems. The three main aspects of biodiversity include genetic diversity, species diversity, and ecosystem diversity. Biodiversity levels can change over time due to long-term natural processes including habitat loss. The importance of biodiversity is vital to all life on earth, determiningRead More biodiversity Essay476 Words   |  2 Pages quot;BIODIVERSITYquot; nbsp;nbsp;nbsp;nbsp;nbsp;Biodiversity, as defined by E.O. Wilson, quot;is meant to be all inclusive- its the genetic based variation of living organisms at all levels, from the variety of genes in populations of single species, through species, on up to the array of natural ecosystems.quot; This includes plants, animals, insects, fungi, bacteria, and all microorganisms. All of these things create what is known as a web. These things interact with each other inRead MoreWhy Is Biodiversity Loss A Concern To Us Today? Biodiversity1520 Words   |  7 Pages Why is biodiversity loss a concern to us today? Biodiversity builds ecosystems, and ecosystems sums up the diversity of all life on Earth. Ecosystems provide the basic necessities of our lives such as food, uncontaminated water, and clean air. Without them humans would be in a very bad situation, ridden with disease and infected my harmful water. Different species belong to each ecosystem provide a vital role in our survival. Mussels and clams clean our ocean and provide a cleaner body of waterRead MoreBiodiversity, Or Biological Diversity1720 Words   |  7 PagesBiodiversity, or biological diversity, is a technical term that captures diversity of the whole living world, from genes to individual species, through plant and animal communities and entire biomes (Defra, 2010). In other words, biodiversity represents genes, species, and ecosystems, which are the structural elements that are nestled within each other, and their ecological functions, in an area (Cepel, 1997; Ozcelik, 2006 ). Biodiversity provides the building blocks for our ecosystems to functionRead MoreBiodiversity Loss and Extinction1220 Words   |  5 PagesBiodiversity loss and Extinction Biodiversity loss can lead to extinction, and hurt human life. It is our responsibility to take care of the environment. We bring in machines that harm the environment and destroy animal life. We need to limit ourselves on how much land and resources we consume. There are major issues that are causing species to become extinct and hurt our way of life and other animals do to the change in food chain. Many of the issues of biodiversity loss can be traced back to human
