Concerted changes in flower morphology and pollinators provide strong evidence on adaptive evolution. Schizanthus (Solanaceae) has zygomorphic flowers and consists of 12 species of annual or biennial herbs that are distributed mainly in Chile and characterized by bee-, hummingbird-, and moth-pollination syndromes. To infer whether flowers diversified in relation to pollinator shifts, we traced the evolutionary trajectory of flower traits and visitors onto a phylogeny based on sequence data from…

Evolution of floral morphology and pollination system in Bignonieae (Bignoniaceae).

Positive and negative evolutionary correlations among traits fit patterns expected under the pollination syndrome perspective, suggesting that interactions between Bignonieae flowers and pollinators likely played important roles in the diversification of the group as a whole.

Evolutionary breakdown of pollination specialization in a Caribbean plant radiation.

Results suggest that pollinator depauperate faunas on islands select for the evolution of reproductive assurance mechanisms, including generalization and autogamy.

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

The Role of Pollinator Shifts in the Floral Diversification of Iochroma (Solanaceae)

It is found that nonphylogenetic models typically fit the data better than phylogenetic models (Brownian motion, Ornstein–Uhlenbeck, and thus results varied little across trees), and species with high nectar reward and large displays are significantly more likely to be pollinated by hummingbirds and less likely toBe pollination by all groups of insects.

Contrasting phylogenetic signals and evolutionary rates in floral traits of Neotropical lianas

Study of the pattern of evolution of quantitative floral traits in a group of Neotropical lianas found opposite signals were found in floral traits associated with the attraction of pollinators and pollen transfer, suggesting a differential role of selection in different floral whorls.

Morphological aspects and phylogenetic analyses of pollination systems in the Tylophora-Vincetoxicum complex (Apocynaceae-Asclepiadoideae) in Japan

Principal component analysis based on 13 floral characters indicated that the size of the pollinator tended to increase with sizes of all characters measured, and species that have developed interstaminal parts of the corona and concealed stigmatic chambers tend to be pollinated by long-tongued insects.

Convergent evolution of floral shape tied to pollinator shifts in Iochrominae (Solanaceae) *

This study uses morphometric approaches to quantify shape variation across the Andean clade Iochrominae and estimates the relationship between changes in shape and shifts in pollination system using phylogenetic comparative methods, infer multiple shifts from an ancestral state of narrow, tubular flowers toward open, bowl‐shaped, or campanulate flowers as well as one reversal to the tubular form.

Phylogenetic analysis of floral integration in Schizanthus (Solanaceae): does pollination truly integrate corolla traits?

The results suggest that corolla integration inpollinator‐dependent species was shaped by pollinator‐mediated selection, and decoupling of nonfunctional traits in these species may result from a relaxation of correlational selection or from selection acting against a default covariation provided by genetic and developmental connections.

Evolution of pollination niches and floral divergence in the generalist plant Erysimum mediohispanicum.

It is conjectured that the geographic variation in pollination niches has contributed to the observed floral divergence in E. mediohispanicum, suggesting a landscape where a few populations locally adapted to their pollination environment (generalist pollination ecotypes) coexist with many populations where this local adaptation has failed and where the plant phenotype is not primarily shaped by pollinators.



Phylogeny and radiation of pollination systems in DISA (Orchidaceae).

The patterns of adaptive radiation in Disa, a large orchid genus in southern Africa, suggest that a few dominant pollinator species in a region may be sufficient to generate diversification in plants through repeated floral shifts that never retrace the same pathways.

It is concluded that pollination systems in Dalechampia have been evolutionarily labile, relative to most morphological features, with repeated parallelisms and reversals.

Predicting mating patterns from pollination syndromes: the case of "sapromyiophily" in Tacca chantrieri (Taccaceae).

The results indicate that despite considerable investment in extravagant display, populations of T. chantrieri are highly selfing, and it is argued that future studies of pollination syndromes would benefit by investigation of both pollination and mating biology.

Floral diversity and evolution in the Solanaceae

The potential for future developmental work on the evolution of floral form in the Solanaceae is examined, particularly in relation to taxa with potential as model organisms such as Petunia and Nicotiana, which are well understood at the genetic level.

Radiation of pollination systems in Gladiolus (Iridaceae: Crocoideae) in Southern Africa

With an inferred minimum of 32 shifts in pollination system in the 165 species in southern Africa, Gladiolus appears to have an unusually labile floral morphology, which may account for its extensive adaptive radiation.

Rapid speciation and the evolution of hummingbird pollination in neotropical Costus subgenus Costus (Costaceae): evidence from nrDNA ITS and ETS sequences.

A molecular clock approach suggests that diversification of the neotropical clade has been recent and rapid and that it coincides with dramatic climatic and geologic changes, Andean orogeny, and the closing of the Panama isthmus that occurred in the Pliocene and Pleistocene epochs.

Floral integration, phenotypic covariance structure and pollinator variation in bumblebee‐pollinated Helleborus foetidus

Results of this study suggest that between‐population differences in magnitude and pattern of floral integration in H. foetidus are probably best explained as a consequence of random genetic sampling in the characteristically small and ephemeral populations of this species, rather than reflecting the selective action of current pollinators.

The relative lability of floral vs. non-floral characters and a morphological phylogenetic analysis of Cobaea (Polemoniaceae)☆

A morphology-based phylogeny was constructed and is congruent in most regards with a previously published molecular phylogeny, but significant incongruence was found in the placement of two taxa.

Pollination Syndromes and Floral Specialization

It is shown that pollination syndromes provide great utility in understanding the mechanisms of floral diversification and the importance of organizing pollinators into functional groups according to presumed similarities in the selection pressures they exert.

The pollination biology of Manfreda virginica (Agavaceae) : relative contribution of diurnal and nocturnal visitors

The pollination biology of Manfreda virginica is studied to measure the relative contribution of nocturnal and diurnal visitors to seed set, and to what extent floral characters and visitation rates predict contribution to seedSet.
