On 'various contrivances': pollination, phylogeny and flower form in the Solanaceae.
Members of the euasterid angiosperm family Solanaceae have been characterized as remarkably diverse in terms of flower morphology and pollinator type. In order to test the relative contribution of phylogeny to the pattern of distribution of floral characters related to pollination, flower form and pollinators have been mapped onto a molecular phylogeny of the family. Bilateral flower symmetry (...
متن کاملMacroevolutionary Tests of Pollination Syndromes: a Reply to Fenster Et Al
Studies of floral ecology and evolution are often centered on the idea that particular floral trait combinations, or syndromes, represent adaptations for particular pollinators. Despite the conceptual importance of pollination syndromes, few macroevolutionary studies have statistically examined the relationship between pollinators and floral traits. Using 15 species of Iochroma, Smith et al. (2...

متن کاملThe role of pollinator shifts in the floral diversification of Iochroma (Solanaceae).
Differences in floral traits among plant species have often been attributed to adaptation to pollinators. We explored the importance of pollinator shifts in explaining floral divergence among 15 species of Iochroma. We examined four continuously varying floral traits: corolla length, nectar reward, display size, and flower color. Pollinator associations were characterized with a continuously va...
متن کاملTight Genetic Linkage of Prezygotic Barrier Loci Creates a Multifunctional Speciation Island in Petunia
Most flowering plants depend on animal vectors for pollination and seed dispersal. Differential pollinator preferences lead to premating isolation and thus reduced gene flow between interbreeding plant populations. Sets of floral traits, adapted to attract specific pollinator guilds, are called pollination syndromes. Shifts in pollination syndromes have occurred surprisingly frequently, conside...
