Population Dynamics Flashcards
Concerned with the factors influencing the expansion, decline, or maintenance of populations
Population Dynamics
What organism was used to study population dynamics?
Apis mellifera
Western Honey Bee
An important aspect of population dynamics that can increase or decrease local population densities
Dispersal
What organism was used to study dispersal?
Eurasian Collared Doves
Changes in the density of predator populations in response to increased prey density
Numerical Responses
Who said this:
Because the reproductive rate of small mammals is so high, there was an almost immediate increase in density with increase in food
Holling (1959)
A group of subpopulations living on such patches connected by exchange of individuals among patches
Metapopulations
A part of a larger population with which it sustains a limited exchange of individuals through immigration and emigration
Subpopulation
What organism was used to study metapopulations?
Parnassius smintheus
Rocky Mountain Parnassian Butterfly
Summarizes the pattern of survival in a population
Survivorship Curve
Book-keeping devices that list both the survivorship and deaths in populations
Life Tables
A group born during the same time period
Cohort
A life table made from data collected from a group born during the same time period
Cohort Life Table
A life table made by recording the age at death of a large number of individuals
Static Life Table
Consists of the proportion of individuals of different ages within a population
Age Distribution
Who studied and what organism was used to study High Survival Among the Young?
Adolf Murie
Dall Sheep
Assumes that the difference in number of individuals in one age class and the next is the result of mortality
Static Life Table
Who studied and what organism was used to study High Mortality Among the Young?
Ahmed Hegazi
Cleome droserifolia
Type of Survivorship Curve
Juvenile survival is high and most mortality occurs among older individuals
Type I
Type of Survivorship Curve
Individuals die at equal rates, regardless of age
Type II
Type of Survivorship Curve
Individuals die at a high rate as juveniles and then at much lower rates later in life
Type III
Indicates periods of successful reproduction, high and low survival, and whether the older individuals in a population are replacing themselves or if the population is declining
Age Distribution
The […] of a population reflects its history of survival, reproduction, and potential for future growth
age distribution
Who studied and what organism was used to study dynamic population in a variable climate?
Rosemary & Peter Grant
Cactus Finch
A term used in mammals and other live-bearing organisms, meaning the number of young born per female in a period of time
Birthrate
Refers to any other processes that produce new individuals in the population
Birth
The tabulation of birthrates for females of different ages in a population
Fecundity Schedule
