Wind pollination (anemophily) of angiosperms probably evolved from insect pollination
(entomophily) in response to pollinator limitation and changes in the abiotic environment …

Background The rich literature that characterizes the field of pollination biology has focused
largely on animal-pollinated plants. At least 10% of angiosperms are wind pollinated, and …

The transport and capture of pollen in∼ 20% of all angiosperm families occurs in air and
water. In other words, pollination is abiotic and occurs via the fluid media, not an animal …

The effects of corolla size, pollen production, and pollinator visitation frequency on pollen
removal (an estimate of male reproductive success) and pollen deposition and seed …

▪ Abstract Examples of androdioecy, the coexistence of males and hermaphrodites, was
unknown when the subject was last reviewed about two decades ago. Since then, several …

Marine life histories differ from terrestrial life histories because seawater is denser and more
viscous than air, because desiccation is not a problem for organisms in water, and because …

Evolutionary biologists have produced a solid body of evidence to explain patterns of
diversification, both within and among species. Recent textbooks are weighted towards …

A fundamental problem in plant population biology and evolutionary ecology is determining
the extent to which natural selection changes the gene pool of populations in the wild. While …

Steady reduction of once-extensive forested habitats into isolated fragments will have
unintended consequences for genetically disrupted tree populations. Gene flow in forest …

Background The male fitness pathway, from pollen production to ovule fertilization, is
thought to strongly influence reproductive trait evolution in animal-pollinated plants. This …
