BIODIVERSITY CONSERVATION g a
Alexander von Humboldt (1769-1859) V The most famous German of his time, was celebrated as a geographer explorer, and naturalist He was less well known for his valuable contributions to the development of the social sciences. Observations Species richness increases with increased explored area (but only up to a limit) The relationship between species richness with wida varieties and the area is a rectangular hyperbola
Species - Area relationships The species-area relationship or species-area curve describes the relationship between the area of a habitat, or of part of a habitat, and the number of species found within that area. V The species-area relationship is usually constructed for a single type of organism, such as all vascular plants or all species of a specific trophic level within MNOSPER NGIOSPER PTERIDOPH TES MS MS
The relationship bet species richness witl varieties and the a straight line. (on a logarithmic sca Log S = log C + Z log Where, S Species richness z = slope of the line (Regression Coefficie C Y- intercept S = (CA)to the power z Log S log C Z I Area
According to ecologists, the value of Z lies in the range of 0.1 0.2 (irrespective of the taxonomic group or the region.) Also found that, the species area relationship among very large areas like the entire continents are much steeper. (0.6 - 1.2) Steeper slopes signifies that number of species found increases faster than the area
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in a taxonomic hierarchy. Examples of taxonomic ranks are species, genu kingdom, domain, Kingdom Phylum Class Order Family Genus Species
Climax community, or climatic climax community, V Is a historic term for a biological community of plants, animals, and fungi V Which, through the process of ecological succession in the development of vegetation in an area over time, have reached a steady state. This equilibrium was thought to occur because the climax community is composed of species best adapted to average conditions in that area.
