Butterflies and moths are conspicuous flower visitors but their role in plant-pollinator
interactions has rarely been quantified, especially in tropical rainforests. Moreover, we have …

Abiotic factors (eg, temperature, precipitation) vary markedly along elevational gradients and
differentially affect major groups of pollinators. Ectothermic bees, for example, are impeded …

Aim To investigate the role of alien plants in mutualistic plant–hummingbird networks,
assessing the importance of species traits, floral abundance and insularity on alien plant …

The pollination syndrome hypothesis predicts that plants pollinated by the same pollinator
group bear convergent combinations of specific floral functional traits. Nevertheless, some …

Since the time of Darwin, biologists have considered the floral nectar spur to be an
adaptation representing a high degree of plant specialization. Nevertheless, some …

Many tropical plants are pollinated by birds and several bird phylogenetical lineages have
specialised to a nectar diet. The long‐assumed, intimate ecological and evolutionary …

Pollination syndromes and their predictive power regarding actual plant-animal interactions
have been controversially discussed in the past. We investigate pollination syndromes in …

The drivers behind plant‐pollinator interactions still need to be fully understood. Previous
research has suggested that observed interactions result from either neutral interaction …

Abstract Background and Aims Floral diversity as a result of plant–pollinator interactions can
evolve by two distinct processes: shifts between pollination systems or divergent use of the …

Floral variation among closely related species is thought to often reflect differences in
pollination systems. Flowers of the large genus Impatiens are characterized by extensive …
