Exam 2

The diversification of a taxonomic group to fill a set of newly available niches.

A population that occurs in multiple different places

Any behavior that increases the fitness of others but decreases the fitness of the altruist

Striking color patterns that serve as a warning signal to predators

A mode of reproduction in which offspring arise from a single parent and inherit its genes directly

The idea that males experience greater variance in reproductive success than females

non-harmful species that resembles a harmful one

Idea that organisms experiencing unpredictable environments should reduce variation in fitness by spreading out risk of reproductive failure

Number of individuals that can be supported by the resources available to a population

Shift in the niches of competing species that reduces competition among them. Natural selection chooses individuals from each species whos resource use overlaps less with that of another species

Spatial variation in the environment that is large relative to mobility of organism

Probability that two alleles are identical by descent (F)

Proportion of genes shared by two individuals (r)

A set of adaptations/counteradaptations in exploitative interaction

A life table based on following a single cohort from birth to the death of the last individual

Experimental design that distinguishes between genetic variation and phenotypic plasticity; phenotypically different plants from different environments grown in same garden, persisting differences are genetic while similar phenotype developments indicate plasticity

any action by one individual that alters probability of behavior in another

Extinction of one species due to competition from another

Link between two or more populations by dispersal of individuals

reduction in genetic contribution to the offspring (in sexual species)

Population processes that change with the population density

Evolutionary population unit; a group of randomly mating individuals

Changes in the relative size of the birth and death rates in human population from preindustrial to industrial societies

The quantitative description of a population and its characteristics
