Chronic intake of fermented floral nectar by wild treeshrews [PDF]

Proceedings of the National Academy of Sciences, 2008
For humans alcohol consumption often has devastating consequences. Wild mammals may also be behaviorally and physiologically challenged by alcohol in their food. Here, we provide a detailed account of chronic alcohol intake by mammals as part of a coevolved relationship with a plant.

The Campsis-Icterus association as a model system for avian nectar-robbery studies

Scientific Reports, 2022
Avian nectar-robbing is common in some floras but its impact on plant-pollinator mutualisms, flowering phenology, and the evolution of floral traits remains largely unexplored.

Pollinator adaptation and the evolution of floral nectar sugar composition [PDF]

Journal of Evolutionary Biology, 2016
AbstractA long‐standing debate concerns whether nectar sugar composition evolves as an adaptation to pollinator dietary requirements or whether it is ‘phylogenetically constrained’. Here, we use a modelling approach to evaluate the hypothesis that nectar sucrose proportion (NSP) is an adaptation to pollinators.

Nectar chemistry is not only a plant's affair: floral visitors affect nectar sugar and amino acid composition [PDF]

, 2021
Floral nectar is the primary reward directly consumed by floral visitors and its chemical composition affects their behaviour and fidelity. In turn, floral visitors are expected to alter floral nectar composition directly or indirectly through the ...

Nectar-dwelling microbes of common tansy are attractive to its mosquito pollinator, Culex pipiens L.

BMC Ecology and Evolution, 2021
Background There is widespread interkingdom signalling between insects and microbes. For example, microbes found in floral nectar may modify its nutritional composition and produce odorants that alter the floral odor bouquet which may attract insect ...

Sodium‐enriched nectar shapes plant–pollinator interactions in a subalpine meadow

Ecology and Evolution
Many plants have evolved nutrient rewards to attract pollinators to flowers, but most research has focused on the sugar content of floral nectar resources.

I've been robbed! - Can changes in floral traits discourage bee pollination?

PLoS ONE, 2019
Some floral visitors collect nectar by piercing flower external whorls, acting as nectar robbers. They leave robbery vestiges, which can cause changes in floral characteristics, including physical and chemical signals that may influence flower ...

Shining a light on UV-fluorescent floral nectar after 50 years

Scientific Reports
Nature is aglow with numerous captivating examples of UV-fluorescence in the animal kingdom. Despite a putative role as a visual signal, exploration of UV-fluorescence in plants and its role in plant-animal interactions is lagging in comparison.
