PPT-Population Density and Distribution

When we examine the population of the world we see that it is distributed unevenly some places are more populated than others Population Distribution The way people are spread across a given area. 248O. Hpopulation is given (H(i)A boundary and a total population NxydS,,1(ii)Travel time (iii)The total uncomfortableness of the space is expressed by the following integral: Exyxydxdy,,,2 xyUx Population Distribution. Population distribution explains . where people . live.. Why do some people prefer to live in region A compared to region B?. What factors are involved in people migrating (moving) from one place to another?. 2.1 Density Curves and the Normal Distributions. 2.2 Standard Normal Calculations. 2.

Population Size and Density. Populations are constantly in flux. They move, change and are influenced by their environment. Various ecosystems and their abiotic components make up a biome. Density. Density describes the number of organisms in a defined area.. Can be found with the following formula:. D. p. = N / A (or D = N / S in Nelson). D. p. is density. N is number of organisms . What is population?. Group of individuals of the same species that live in the same area. Does population change?. Sea otters, kelp, and sea urchins. Kelp forests offer a habitat for sea otters. Sea urchins feed on kelp. Species distribution. Density . and size are useful measures for characterizing populations. Scientists gain additional insight into a species' biology and ecology from studying how individuals are spatially distributed. Dispersion or distribution patterns show the spatial relationship between members of a population within a habitat. Patterns are often characteristic of a particular species; they depend on local environmental conditions and the species' growth characteristics (as for plants) or behavior (as for animals).. and Applications . (Common Core Standard G-MG.2) Practice applying concepts of density with an area and volume modeling situation.. What is Density??. Density is a measure of how much matter is in a certain volume or area .. 3 characteristics of all populations. Density. The number of organisms of the same species per unit area (25 people per classroom). Dispersion. The pattern of population distribution. Ranges. Limited by biotic and abiotic factors. Trends. Decentralization of jobs. Decentralization of people. The Spatial Distribution of Jobs and People. Distribution of Employment. Employment decentralization. In 1948 jobs in central city were twice those in suburban areas. Most . populations . live together in clumps or patches.. Populations can grow, shrink, or remain stable. Population Dynamics. Age Structure. – proportions of individuals at various ages. Population Density. Course Objectives.
