Evolutionary theory developed by J. Philip Grime in collaboration with Simon Pierce describing the general limits to ecology and evolution based on the trade-off that organisms face when the resources they gain from the environment are allocated between either growth, maintenance or regeneration – known as the universal three-way trade-off.
Understanding the differences between the CSR theory and its major alternative the R* theory has been a major goal in community ecology for many years.
Size-asymmetric competition refers to situations in which larger individuals exploit disproportionately greater amounts of resources when competing with smaller individuals.
Contrasting assumptions about size-asymmetry characterise the two leading and competing theories in plant ecology, the R* theory and the CSR theory.
Qualitative and quantitative measures of a given invasive species probability to invade a given ecosystem.
This is shown directly through Tilman's R* rule.
Plant strategies include mechanisms and responses plants use to reproduce, defend, survive, and compete on the landscape.
G. David Tilman developed the R* rule in support of resource competition theory.
