Concepts

The concept that organisms face competing demands for limited resources during development that create trade-offs between different fitness components

The spatial arrangement and connectivity of subpopulations across a landscape that influences local population dynamics

Some environments will be resource rich and produce a high amount of offspring (sources) while other environments will be resource low and produce a low amount of offspring (sinks)

A principle stating that allele and genotype frequencies remain constant in a population under certain conditions

Population response where decreases in fitness due to other factors are offset by increases in another demographic parameter
