Abstract Germination timing of Arabidopsis thaliana displays strong plasticity to geographic
location and seasonal conditions experienced by seeds. We identified which plastic
responses were adaptive using recombinant inbred lines in a field manipulation of ...

The size of eggs that evolves within a population will in theory reflect a balance between
selection for large eggs and for increased fecundity. Theory also predicts that the intensity of
selection for large eggs (via effects of egg size on progeny survival and growth) increases ...

... paternally influenced. Since fruit set, seeds per fruit, and seed weight are traits arguably
related to fitness, the additive genetic variance in these traits should reflect the potential
for natural selection to operate on them. I specifically ...

Japanese camellia (Camellia japonica) and its seed predator, the camellia weevil (Curculio
camelliae), provide a notable example of a geographic mosaic of coevolution. In the species
interaction, the offensive trait of the weevil (rostrum length) and the defensive trait of the ...

Abstract Plants may express two separate seed-size characters during their lifetimes: the
size of the seeds from which they germinate (initial seed size) and the mean size of seed
they produce as adults (maternal seed size). Many empirical studies indicate that ...

The effect of various environmental conditions during dormancy on the germination
response of Oenothera seeds was tested. Germination response varied widely according to
the strain of seed as well as the storage conditions. The storage of seed wet at 15⚬ C was ...

Abstract• Premise of the study: The processes maintaining flower color polymorphisms have
long been of evolutionary interest. Mechanistic explanations include selection through
pollinators, antagonists, local environments, drift, and pleiotropic effects. We examined the ...

Complex ecological characters such as flowers are likely the outcome of diverse, interacting
selection pressures from both mutualistic pollinators and antagonistic herbivores. These
interactions are expected to be particularly strong when both pollinator and herbivore ...
