Phylogenetic evidence for pollinator-driven diversification of angiosperms.
TLDR
It is shown that pollinator shifts are common, being associated with at least a quarter of documented divergence events, and shift frequency and directionality vary extensively, owing to variation in intrinsic factors such as floral features and phylogenetic history.Abstract:
Since Darwin, the diversity of flowers has been attributed to selection by pollinators. Although pollinators commonly act as selective agents on floral traits, determining the extent to which they have influenced angiosperm diversification requires a historical perspective. Here we review recent studies that combine species-level phylogenies with pollinator data and show that pollinator shifts are common, being associated with at least a quarter of documented divergence events. However, shift frequency and directionality vary extensively, owing to variation in intrinsic factors such as floral features and phylogenetic history, as well as extrinsic factors such as interactions with local pollinator assemblages. Despite technical advances, phylogenies remain limited in their power to distinguish among various pollinator-driven evolutionary processes.read more

TL;DR: The first systematic review of pollination syndromes that quantitatively tests whether the most effective pollinators for a species can be inferred from suites of floral traits for 417 plant species supports the syndrome concept.

Pollinator-driven ecological speciation in plants: new evidence and future perspectives
Timotheüs van der Niet,Timotheüs van der Niet,Timotheüs van der Niet,Rodney Peakall,Steven D. Johnson +4 more
TL;DR: Evidence for the four components of ecological speciation in the context of plant-pollinator interactions is focused on, and it is predicted that examples of pollinator-driven speciation will be among the most widespread and compelling of all cases of ecological Speciation.

Real-time divergent evolution in plants driven by pollinators
TL;DR: This study uses experimental evolution with fast cycling Brassica rapa plants to demonstrate adaptive evolution driven by different pollinators, showing pollinator-driven divergent selection as well as divergent evolution in plant traits.

Confluence, synnovation, and depauperons in plant diversification.
TL;DR: This review of the empirical phylogenetic literature on plant diversification highlights challenges in separating the effects of speciation and extinction, in specifying diversification mechanisms, and in making convincing arguments by introducing the term 'synnovation' and 'confluence' for an interacting combination of traits with a particular consequence.

The evolution of plant reproductive systems: how often are transitions irreversible?
TL;DR: The directionality of many transitions clearly refutes the notion of unconstrained reproductive flexibility, but novel adaptive solutions generally do not retrace earlier patterns of trait evolution.

Pollination Syndromes and Floral Specialization
TL;DR: 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.

Bayesian estimation of ancestral character states on phylogenies.
TL;DR: This work describes how to combine information about the uncertainty of the phylogeny with uncertainty in the estimate of the ancestral state and shows how to reconstruct ancestral states of uncertain nodes using a most-recent-common-ancestor approach.

Adaptive Radiation of Reproductive Characteristics in Angiosperms, I: Pollination Mechanisms
TL;DR: In angiosperms, the adaptive significance of differences between most higher categories, as well as between a large proportion of related species, is most probably associated with reproductive efficiency and successful establishment of seedlings rather than with any of the morphological characteristics of the vegetative parts.
