Pollinator-Mediated Selection on Floral Display and Spur Length in the Orchid Gymnadenia conopsea (2010, background): “…trait mapping in Aquilegia has indicated that an evolutionary trend for longer spurs is associated with shifts to pollinators with lon- ger tongues (Whittall and Hodges 2007), and population mean spur length has been found to be positively correlated with the tongue lengths of local pollinators…”
Extended phylogeny of Aquilegia: the biogeographical and ecological patterns of two simultaneous but contrasting radiations (2010, background): “The main pollinators can be syrphiid flies, bumblebees, hawkmoths or hummingbirds (Whittall and Hodges 2007; Tang et al. 2007).”
Associations between floral specialization and species diversity: cause, effect, or correlation? (2008, background): “…spiral or serial pollinator switches, as appears to be the case for the long spurs of some orchid and columbine flowers and their long-tongued pollinators (Darwin 1877; Nilsson et al. 1987; Nilsson 1988; Wasserthal 1997; Whittall and Hodges 2007; Ennos 2008; Hodges and Whittall 2008).”
Ecology of plant speciation (2010, background): “Taken as a whole, these findings argue strongly that transgressive hybridization and ecologi cal selection have played a central role in speciation and ecological diver gence in North American sunflowers.”
PART OF A SPECIAL ISSUE ON POLLINATOR-DRIVEN SPECIATION Pollinator shifts and the evolution of spur length in the moth-pollinated orchid Platanthera bifolia (2014, background): “Based on a comparative phylogenetic study, Whittall and Hodges (2007) suggested that interspecific differences in spur length in Aquilegia have evolved as a result of pollinator shifts rather than coevolution.”
Interactions between hawkmoths and flowering plants in East Africa: polyphagy and evolutionary specialization in an ecological context (2013, background): “Overall, asymmetry in these flower–hawkmoth interactions, especially those involving short-tubed flowers and short-tongued moths, makes it unlikely that they have been shaped by pairwise coevolution (Janzen, 1980; Whittall & Hodges, 2007).”
The role of frugivory in the diversification of bats in the Neotropics (2012, background): “Selection generated by pollinator shifts promotes morphological diversification but does not promote species diversity (Whittall & Hodges, 2007).”
Explaining Evolutionary Shifts between Bee and Hummingbird Pollination: Convergence, Divergence, and Directionality (2008, background): “Whittall and Hodges (2007) studied them all, revealing that much of floral evolution occurred through pollinator shifts.”
