ENDANGERED MUTUALISMS: The Conservation of Plant-Pollinator Interactions
▪ Abstract The pollination of flowering plants by animals represents a critical ecosystem service of great value to humanity, both monetary and otherwise. However, the need for active conservation ofExpand
Tolerance of pollination networks to species extinctions
Mutually beneficial interactions between flowering plants and animal pollinators represent a critical ‘ecosystem service’ under threat of anthropogenic extinction. We explored probable patterns ofExpand
Global warming and the disruption of plant-pollinator interactions.
Anthropogenic climate change is widely expected to drive species extinct by hampering individual survival and reproduction, by reducing the amount and accessibility of suitable habitat, or byExpand
Flower Constancy, Insect Psychology, and Plant Evolution
Abstract Individuals of some species of pollinating insects tend to restrict their visits to only a few of the available plant species, in the process bypassing valuable food sources. The question ofExpand
Flower Constancy: Definition, Cause, and Measurement

A pollinator that restricts its visits to one flower type, even when other rewarding types are accessible, can be said to exhibit flower constancy. This usage distinguishes constancy from fixedExpand
Plant-pollinator interactions: from specialization to generalization.
Just as flowering plants depend on their pollinators, many birds, insects, and bats rely on plants for energy and nutrients. This plant-pollinator relationship is essential to the survival of naturalExpand
Competition for Hummingbird Pollination and Sequential Flowering in Two Colorado Wildflowers
The simultaneous flowering of co—occurring plant species with similar pollinator affinities may result in interspecific pollen transfer and consequent fecundity reductions due to wastage of pollen,Expand
New frontiers in competition for pollination.
BACKGROUND Co-flowering plant species frequently share pollinators. Pollinator sharing is often detrimental to one or more of these species, leading to competition for pollination. Perhaps because itExpand

Introduced alien species influence many ecosystem services, including pollination of plants by animals. We extend the scope of recent ‘single species’ studies by analysing how alien plant speciesExpand
The production of dilute nectars by hummingbird and honeyeater flowers
A survey of data from tropical and temperate regions confirms that nectars of hummingbird and honeyeater flowers are dilute, especially relative to nectars of bee flowers. We use these data, alongExpand
