APES Population, Questions and answers, 100% Accurate. Rated A+ population ecology - ✔✔-The study of populations in relation to the environment, including environmental influences on populati... on density and distribution, age structure, and variations in population size population density - ✔✔-number of individuals per unit area birth rate - ✔✔-the number of babies born per 1,000 people in an area death rate - ✔✔-the number of deaths per 1,000 people in an area growth rate - ✔✔-the natural increase of a population, expressed as percent per year dispersal - ✔✔-movement of individuals among populations immigration - ✔✔-dispersal of individuals into a population from another area or country emigration - ✔✔-dispersal of individuals from a population, bound for another are or country in which to live natural increase rate - ✔✔-The percentage growth of a population in a year, computed as the crude birth rate minus the crude death rate. biotic potential - ✔✔-maximum rate at which a population could increase under ideal conditions exponential population growth - ✔✔-Growth of a population in an ideal, unlimited environment, represented by a J-shaped curve when population size is plotted over time. environmental resistance - ✔✔-All the limiting factors that tend to reduce population growth rates and set the maximum allowable population size or carrying capacity of an ecosystem carrying capacity - ✔✔-(K) represents the largest population that can be maintained for an indefinite period by a particular environmnet survivorship - ✔✔-probability that a given individual in a population will survive to a particular age density- dependent factor - ✔✔-an environmental factor whose effects on a population change as population density change: it tends to retard pop. growth as population density increases and enhance pop growth as pop density decreases density- independent factor - ✔✔-an environmental factor that affects the size of pop but is not influenced by changes in pop density zero population growth - ✔✔-when a pop is no longer increasing (or decreasing) (b)rate = (d)rate doubling time - ✔✔-the number of years it will take a population to double in size, given its current growth rate infant mortality rate - ✔✔-the # of infant deaths per 1,000 live births replacement- level fertility - ✔✔-# of children a couple must have to "replace" themselves total fertility rate - ✔✔-the average number of children born to each woman during her lifetime MDCs - ✔✔-USA, Canada, France, Germany, Sweden, Australia, Japan MDC - ✔✔-low growth rate highly industrial low birth rates low infant mortality rates longer life expectancy moderately developed countries - ✔✔-(b)rates & IMR are higher than MDCs. medium level of industrialization LDCs - ✔✔-Bangladesh, Nigera, Ethiopia, Laos, Cambodia LDC - ✔✔-opposite of MDC status demographic transition - ✔✔-The process of change in a society's population from a condition of high crude birth and death rates and low rate of natural increase to a condition of low crude birth and death rates, low rate of natural increase, and a higher total population. preindustrial stage - ✔✔-(b)rates and (d)rates are high, pop grows at a modest rate. IMF is high (Finland during the late 1700s) transitional stage - ✔✔-lowered (d)rate, (b)rate is still high, pop grows rapidly (Finalnd in mid-1800s) industrial stage - ✔✔-decline in (b)rate and takes place during industrialization process. pop growth, (d)rate is low (Finland in early 1900s [Show More]
