Associations between floral specialization and species diversity: cause, effect, or correlation? (2008, methodology): “commonly defined as use of many of the available pollinators in a habitat and specialized pollination as use of few of the available pollinators (Waser et al. 1996; Fenster et al. 2004; Armbruster 2006).”
Why flower visitation is a poor proxy for pollination: measuring single‐visit pollen deposition, with implications for pollination networks and conservation (2013, background): “Other possible proxies such as ‘contact with reproductive structures’ (Petanidou & Potts 2006; Gibson et al. 2011), number of stigma touches (Olsen 1997), measurements of visit duration (Fishbein & Venable 1996; Kaiser-Bunbury et al. 2010) and of pollen removal (Ivey, Martinez & Wyatt 2003) are…”
The best wildflowers for wild bees (2019, background): “These plants chiefly target long-tongued bumblebees (Corbet 2006), and the sowing of these seed mixtures on farms has led to an increase in the abundance of a few common bumblebee species (Wood et al.”
Generalist foraging of pollinators: diet expansion at high density (2008, background): “Compared to a richness measure, the Levins index downplays the importance of rarely visited hosts, and is best used to compare the diets of insects foraging within the same community (Cane & Sipes 2006; and references therein).”
Foraging distances in six species of solitary bees with body lengths of 6 to 15 mm, inferred from individual tagging, suggest 150 m-rule-of-thumb for flower strip distances (2020, background): “While the two Osmia species are polylectic (meaning they forage for pollen on a wide taxonomic variety of plants; Cane and Sipes 2006), the others are oligolectic (they collect pollen at only a few plant families), with Chelostoma florisomne specialized on Ranunculus (Ranunculaceae), C.”
Indices, Graphs and Null Models: Analyzing Bipartite Ecological Networks (2009, background): “Previously heralded as a showcase for co-evolution by ecologists (Darwin 1862), evidence has now accumulated that shows strict specialization to be the exception rather than the rule (Waser et al. 1996; Waser 2006).”
Ecological networks, nestedness and sampling effort (2007, background): “Vázquez & Aizen (2006) indicated that relative specialists are less abundant than generalists, inducing a potential sampling bias towards the core of generalist species and thus underestimating the presence of the more specialized species.”
The tolerance of island plant–pollinator networks to alien plants (2011, background): “We also present network connectance, C = 100 · (I ⁄S) based on the mean connectance for each time period (Medan et al. 2006).”
Nectar‐feeding bird and bat niches in two worlds: pantropical comparisons of vertebrate pollination systems (2008, background): “These terms have been widely discussed in the recent literature (e.g. Waser et al., 1996; Armbruster et al., 2000; Johnson & Steiner, 2000; Fenster et al., 2004; Armbruster, 2006; Ollerton et al., 2006, 2007), and several types of specialization need to be distinguished.”
Explaining Evolutionary Shifts between Bee and Hummingbird Pollination: Convergence, Divergence, and Directionality (2008, background): “We suggest, however, that Aquilegia differs from Penstemon and the other genera we have mentioned in having many anthers, which might predispose it to sphingophily.”
