Concepts

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

Growth limitation of organisms due to insufficient availability of essential nutrients like nitrogen or phosphorus

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

The hypothesis that disposing of excess dietary nutrients imposes a growth cost on organisms, creating hump-shaped relationships with diet stoichiometry

Paedomorphosis becomes the preferred life strategy when growing conditions such as prey abundance, water temperature, and population density are poor, so individuals opt to cut losses and become sexua...

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

Biogeographic classification of species based on their broader distributional affinities and evolutionary origins

Habitat structure that provides protection from predation by offering shelter or hiding places
