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

Natural selection on floral traits that occurs through differential pollinator visitation and resulting differences in reproductive success

The rate at which plants convert carbon dioxide and water into glucose using light energy, measured as gas exchange

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...

The hypothesis that predispersal seed predators preferentially attack high-quality flowers, potentially masking negative effects of environmental stressors

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

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

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

Percentage of leaf biomass composed of water, calculated as difference between wet and dry weight divided by wet weight

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 impacts of dust from unpaved roads on plant physiology and reproduction

Chemical compounds emitted by plants as signals to other organisms, interrelated with atmospheric chemistry and climate change

Theory suggesting that offspring sex ratios might vary according to maternal condition, hence females should vary the sex of their offspring according to their ability to physically invest in their of...
