Concepts

A process by which adaptive evolutionary change occurs sufficiently rapidly to counteract a decline in population size under initially unfavorable conditions

Secondary metabolites that mediate interactions with herbivores and pathogens in Brassicaceae

Movement of genes between populations through migration and reproduction

Widespread reductions in pollinator abundance and diversity observed globally, attributed to multiple environmental stressors

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

Ability of forest ecosystems to maintain function during water-limited conditions through adaptive water use strategies

The study of traits controlled by multiple loci with continuous phenotypic distributions and measurable heritability

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...

The mechanism by which organisms measure day and night length to regulate seasonal activities like diapause

Statistical approach to identify genetic variants associated with traits by scanning the entire genome

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

When single genes or alleles influence multiple, seemingly unrelated traits

Biochemical pathway producing anthocyanin pigments responsible for purple coloration

Selection pressure from non-biological environmental factors such as rain or wind

Chromosomal rearrangement where a segment is reversed in orientation, potentially suppressing recombination and maintaining linkage between beneficial alleles

An individual locus shows strong adaptive fitness effects in one habitat, but little or no cost in other habitats

Genetic variation in defensive traits maintained within populations

Requirement for extended cold treatment to trigger flowering in some plant species

The proportion of aliphatic GS derived from branched-chain amino acid (Val and Ile) precursors, representing quantitative trait variation controlled by known biosynthetic locus

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

The introduction of a species to previously inhabited areas or to new suitable regions
