Biology Forum Why did the ‘Diversity’ term be coined? Biodiversity is the biological variety and variability of life on Earth. The variety and variability of animals, plants and micro-organisms that are used directly or indirectly for food and agriculture, including crops, livestock, forestry and fisheries. for atoms of other elements. Biodiversity can be measured globally or in smaller settings, such as ponds. In each of these disciplines, diversity is a measure of the range and distribution of certain features within a given population. agerdman16 PLUS. ( general) The state of being diverse; variety. everything that is … Biodiversity comes from two words Bio meaning life and diversity meaning variability. Agro-forest An agro-forest is a complex of treed areas within an area that is broadly characterised as agricultural or as an agro-ecosystem. Biological Diversity. Genetic Diversity Explained With the Best Available Examples. However, it is common for conservation biologists to speak of species diversity even when they are actually referring to species richness. Biodiversity, also called biological diversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth. The article presents a brief overview of the commonest indices used in ecological studies. Much of the early work was based on evidence from mitochondrial DNA, but this has been supplemented by important information from nuclear DNA from both the … Genetic diversity refers to both the vast numbers of different species as well as the diversity within a species. Information and translations of unity in diversity in the most comprehensive dictionary definitions resource on the web. Diversity is simply counts of taxa (sets of organisms related together by certain characteristics). At just over one inch long, it is the smallest known chameleon. Lewontin’s Fallacy: The fallacious (misleading, and irrelevant) claim that there is more genetic diversity within a population than between populations. Taxonomic diversity is relative abundance of a species as well as the ancestor descendant relationships of species to each other. Fundamental divisions … But if there are 40 foxes and 42 dogs, the community is quite even. Inbred organisms may suffer from what is called reduced biological fitness. The current kingdoms are the Archaebacteria, Eubacteria, protists, fungi, plants and animals. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. The number and variety of … Biology 1: Molecular Diversity. Biological diversity is the variety of life on earth. This includes all the different plants, animals, and microorganisms; the genes they contain; and the ecosystems they form on land and in water. What is Taxonomic diversity? The diversity definition refers to the existence of variations of different characteristics in a group of people. Species Diversity is simply the number and relative abundance of species found in a given biological organisation (population, ecosystem, Earth). Definition for Diversity. It is increased by new genetic variation and reduced by extinction and habitat degradation. Biological diversity, or biodiversity, is a generic term for the variety of life on Earth.Such variety is described in Genesis as the "swarms" of creatures Earth brings forth (Gen. 1:20-25). length. Biological diversity is constantly changing. In addition to diversity among species, the concept of biodiversity includes the genetic diversity within species. One example is our own species, for we differ in a wide variety of characteristics that are partly or wholly genetically determined, including height, weight, skin and eye colour, behavioral traits,... An ecosystem is a community plus the physical environment that it occupies at a given time. The term “Biodiversity” refers to the heterogeneity present in the world or a habitat, ranging from macromolecules within the cells to biomes. What Does Species Diversity Mean? Diversity of cells The cell is the tiniest building unit in the organism’s body capable of carrying out all the functions of life , Cells are vary in shape , structure and size, The biggest cell in size is the cell of the unfertilized egg of ostrich , The tiniest cell in size is the bacterial cell , … Figure 1. Biology > Molecular Genetics > Genetic Diversity – Definition, Importance, Examples. Species diversity: Measures the species number variations in different genera at a particular habitat Evolution and diversity result from the interactions between organisms and their environments and the consequences of these interactions over long periods of time. This includes all the different plants, animals, and microorganisms; the genes they contain; and the ecosystems they form on land and in water. One basic measure of biodiversity is species, though other indicators run a spectrum from genetic alleles (variants) through ecosystems and landscapes. In biology, diversity may pertain to the variation of life forms present in different ecosystems. An ecosystem can exist at any scale, for example, from the size of a small tide pool up to the size of the entire biosphere. Species are the basic units of biological classification and hence, this is the measure most commonly associated with the term 'biodiversity'. Meanings range from a state or fact of being diverse or different, to a variety of opinions. The core of the orthodoxy consists of three dogmas: - Gender is a social construct. Biology (A-Level Revision) Applied Ecology. Leukophobia: The fear of white people organizing racially. The aquatic plants include red, brown and green algae and the land plants include mosses, ferns, gymnosperms and angiosperms. The resultant diversity indices are a key feature of communities which can throw light on many aspects of conservation. In the Department of Biology, we continue to strive for an inclusive and welcoming departmental culture that recognizes and encourages individual differences, that fosters the constructive expression of ideas, and that promotes shared values such as intellectual curiosity, creativity, collegiality, and sense of mission. Organisms belong to one of six kingdoms of life. Biology Plant Biology Plant Diversity PLANT DIVERSITY - AN ASSORTMENT OF AWESOMENESS Land plants are amazingly diverse and adaptable, but they owe their leap out of the pond as it were to some hereditary assistance 400 mya from their closest living relatives, green algae.
