What is random population distribution?
Individuals of a population can be distributed in one of three basic patterns: uniform, random, or clumped. In a random distribution, individuals are spaced at unpredictable distances from each other, as seen among plants that have wind-dispersed seeds.
What is uniform population distribution?
Individuals may be distributed in a uniform, random, or clumped pattern. Uniform means that the population is evenly spaced, random indicates random spacing, and clumped means that the population is distributed in clusters.
What can cause a population to be in a uniform distribution?
Uniform patterns of dispersion are generally a result of interactions between individuals like competition and territoriality. Clumped patterns usually occur when resources are concentrated in small areas within a larger habitat or because of individuals forming social groups.
What is clumped population distribution?
Clumped dispersion is when individuals in a population are clustered together, creating some patches with many individuals and some patches with no individuals. In uniform dispersion, individuals are spaced evenly throughout an area. It can also be caused by social interactions between individuals.
What are the physical and human factors that influence the distribution of population?
Physical factors that affect population density include water supply, climate, relief (shape of the land), vegetation, soils and availability of natural resources and energy. Human factors that affect population density include social, political and economic factors.
What are the factors affecting world population distribution?
Physical factors that affect population distribution include altitude and latitude, relief, climate, soils, vegetation, water and location of mineral and energy resources. It is important to note that most of the physical factors influence population distribution only indirectly through climatic conditions.
What are three human induced factors that may influence carrying capacity?
We can think of carrying capacity as being determined by three main factors, 1. The size of the population, 2. The amount of resources in an area and, 3. How the population uses the available resources.
