Concepts

Selection where individual fitness depends on the local frequency rather than global frequency, creating population structure with groups varying in genetic and phenotypic composition

The formation of new species involves divergence of phenotypes and development of reproductive isolation, where initial divergence results from divergent natural selection and reproductive isolation a...

Demographic models that project population dynamics using continuous size or stage distributions

Chemical compounds emitted by flowers that contribute to floral scent and can influence pollinator attraction and plant-herbivore interactions

Movement of genes between populations through migration and reproduction

A geographic region where genetically distinct populations meet and produce offspring of mixed ancestry

Interbreeding between taxa that alters the pool of genetic variation available for population responses to changing environments

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

Reproduction in which pollen from a flower fertilizes ovules in the same flower or on the same plant

The geographic or environmental boundaries beyond which species cannot persist, potentially influenced by biotic interactions

Per-capita population growth rate λ calculated as the dominant eigenvalue of the projection matrix at equilibrium

Transparent chambers commonly used in climate change experiments to raise air and soil temperature in remote areas by creating a passive warming effect

Fine particulate matter generated by vehicular traffic on unpaved roads that settles on plant surfaces

The tendency for flower foragers to visit a single flower species during foraging trips even when alternative rewarding species are available

The number and proportion of developed seeds produced by an individual plant, used as a measure of fecundity

The duration from when a flower's corolla first opens until either the corolla falls off or the stigma closes after opening

Selective feeding behavior of herbivores that favors certain plant traits or genotypes over others

Mathematical models that represent how different pollinators perceive color based on their photoreceptor sensitivities and opponent color processing

Genetic mechanisms that prevent self-fertilization by recognition and rejection of self pollen

Sequential developmental stages of individual flowers progressing through male phases (M1, M2), inter-phase, and female phase

Color-based visual contrast as perceived by animal visual systems

The extent of possible variation in a particular phenotypic trait where different dimensions represent the extent of phenotypic variation in two traits

Conflicts between opportunities of a flower to receive fitness contributions from different visitor groups due to competition over limited floral resources
