Genet is a plant produced by sexual reproduction. 9. 2 the distribution of a population defines its spatial location. An area that encompasses all individuals of a species, the distributions describes the population"s geographic range. Population distribution is influenced by suitable environmental conditions -> high tolerance allows for widespread geographic range. Individuals are not distributed equally in a geographic range. Crude density is number of individuals in an area. However individuals do not cover an area equally. Uniform distribution came from negative interaction, i. e. competition. Spatial distribution of individuals can be described at multiple spatial scales. Ecological density is the number of individuals per unit of available living space. Quadrats, used mostly for sessile animals, good for uniform, not clumped. Age structure is the number or proportion of individuals in different age classes.
