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. Larger areas tend to contain larger numbers of species, and empirically, the relative numbers seem to follow systematic mathematical relationships. [ 1 ]
Kleiber's law, like many other biological allometric laws, is a consequence of the physics and/or geometry of circulatory systems in biology. [5] Max Kleiber first discovered the law when analyzing a large number of independent studies on respiration within individual species. [2]
n 0 is the number of species in the modal bin (the peak of the curve) n is the number of species in bins R distant from the modal bin a is a constant derived from the data. It is then possible to predict how many species are in the community by calculating the total area under the curve (N): =
Rarefaction curves generally grow rapidly at first, as the most common species are found, but the curves plateau as only the rarest species remain to be sampled. [ 1 ] The issue that occurs when sampling various species in a community is that the larger the number of individuals sampled, the more species that will be found.
the length of the organism, as the surface area of just the front 2/3 of the organism has an effect on the drag. The resistance to the motion of an approximately stream-lined solid through a fluid can be expressed by the formula: C fρ (total surface)V 2 /2, [19] where: V = velocity ρ = density of fluid C f = 1.33R − 1 (laminar flow) R ...
The rank abundance curve visually depicts both species richness and species evenness. Species richness can be viewed as the number of different species on the chart i.e., how many species were ranked. Species evenness is reflected in the slope of the line that fits the graph (assuming a linear, i.e. logarithmic series, relationship).
The distributions of a wide variety of physical, biological, and human-made phenomena approximately follow a power law over a wide range of magnitudes: these include the sizes of craters on the moon and of solar flares, [2] cloud sizes, [3] the foraging pattern of various species, [4] the sizes of activity patterns of neuronal populations, [5] the frequencies of words in most languages ...
