Population Dynamics Flashcards
a group of individuals of the same species associated with a specific area or place
population
a record of the birth and death rates for organisms at the different stages age-based or size-based
life tables
basic tool for analyzing population dynamics
cohort table
organisms born at approximately the same time
cohort
average number of daughters produced by a female that lives to a maximum age reached in that cohort
Gross Reproductive Rate (GRR)
average number of daughters produced by each female entering the population
Net Reproductive Rate (NRR)
a simplified graphical presentation of elements of the life table
survivorship curves
lack of skin pigment
albinism
condition of having extra digits on hands or toes
polydactyly
occurs at a higher frequency in maels than in females
baldness
a rare disorder wherein blood does not clot normally due to lack of blood-clotting proteins
hemophilia
a picture of a population at a specific time
age structure
growth of the population without environmental resistance factors
exponential
the total number of that the individuals that the environment can support
carrying capacity
population growth rate ultimately plateau when the resources get diminished
logistics
factors that limit population growth: biotic factors
density-dependent factors
factors that limit population growth: abiotic factors
density-independent factors

Jean Baptise de Lamarck
species evolve by inheriting characteristics acquired by use and disuse of body parts
Lamarckism
a group of individuals that actually or potentially interbreed in nature
species
