Sustainability” is a popular idea these days. . What does “sustainability” in the ecosystem mean?. What does “sustainability” in human communities mean?. W. O. R. K. T. O. G. By: Taylor Thomason. Heather Caldwell. Intro. In this project we observed the effect the cheetah population had on the springbok population. . We discovered that through this the correlation between the two is positively moderate.. SWBAT compare the factors affecting animal populations to human populations . Why should you study human populations and their growth?. Bellwork. Demography. . is the study of the characteristics of populations, especially human populations.. : . . AP Environmental Science . Human Population Dynamics. There are just three sources of change in population size:. Fertility. Mortality. "natural decrease" refers to population decline resulting from more deaths than births. Environmental Science. 9.1 Studying Human Populations. The human population has grown . faster. . in the . 20th. . century than it has ever before.. This rapid growth has led to . environmental problems. . The Human Population. . More than 6.3 billion people currently . * U.S. 300 . . Million. Last 25 yrs population grew by 2 billion. Projected that population will be 10 billion by 2050. An interbreeding group of the . same species. living in the same general area. may be distinguished by natural or . . arbitrary boundaries. Population Density vs Dispersion. the number of individuals per unit area or volume. . Core. Define population as a group of organisms of one species, living in the same area at the same time.. State the factors affecting the rate of population growth for a population of an organism (limited to food supply, predation and disease), and describe their importance .Identify the lag, exponential (log), stationary and death phases in the sigmoid population growth curve for a population growing in an environment with limited resources. is concerned with the question of whether a particular allele or genotype will become more common or less common over time in a population, and Why.. Example: . Given that the CCR5-. D. 32 allele confers immunity to HIV, will it become more frequent in the human population over time?. Introduction to linking demography, population growth and extinction due to climate warming. What is Population Ecology? . Goal is to understand . factors. and . processes. that govern . abundance. 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. SW: discuss with their groups how estimating a population could be used in a real world situation.. Population Ecology. Measuring a population. Growth Curves. Biotic Potential vs. Environmental. Resistance. . Distribution. Spread of . population; pattern of human settlement. Aka dispersed distribution. Relates to density. Humans live only in certain areas (that they can get food, water, and shelter) and there is a pattern to it.
