Concepts

Movement of genes between populations through migration and reproduction

Selection that maintains multiple alleles in a population at frequencies above those expected from mutation alone

A gradual change in a trait across an environmental gradient, where width is expected to be proportional to dispersal distance divided by square root of difference in selection between ends of the cli...

How plant population density affects individual plant growth, morphology, and susceptibility to herbivory through competition and resource availability

Genetic variation in defensive traits maintained within populations

A state where viable seeds do not germinate immediately even under favorable conditions

Selection on body mass accounting for juvenile survival until reproduction but may weaken after recruitment
