Plant–pollinator interactions and floral and nectar traits shape the diversity of the nectar mycobiome [PDF]
Scientific ReportsBeyond its essential role in plant–pollinator interactions, floral nectar serves as habitats for diverse fungal communities that can influence plant–animal mutualism.

The role of jasmonates in floral nectar secretion. [PDF]
PLoS ONE, 2010 Plants produce nectar in their flowers as a reward for their pollinators and most of our crops depend on insect pollination, but little is known on the physiological control of nectar secretion.

Floral nectar guide patterns discourage nectar robbing by bumble bees. [PDF]
PLoS ONE, 2013 Floral displays are under selection to both attract pollinators and deter antagonists. Here we show that a common floral trait, a nectar guide pattern, alters the behavior of bees that can act opportunistically as both pollinators and as antagonists ...

Yeasts in floral nectar: a quantitative survey [PDF]
Annals of Botany, 2009 One peculiarity of floral nectar that remains relatively unexplored from an ecological perspective is its role as a natural habitat for micro-organisms. This study assesses the frequency of occurrence and abundance of yeast cells in floral nectar of insect-pollinated plants from three contrasting plant communities on two continents.

Shining a light on UV-fluorescent floral nectar after 50 years [PDF]
Scientific ReportsNature 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.

How scent and nectar influence floral antagonists and mutualists
eLife, 2015 Many plants attract and reward pollinators with floral scents and nectar, respectively, but these traits can also incur fitness costs as they also attract herbivores.

Contrasting effects of yeasts and bacteria on floral nectar traits. [PDF]
Ann Bot, 2018 Flowers can be highly variable in nectar volume and chemical composition, even within the same plant, but the causes of this variation are not fully understood. One potential cause is nectar-colonizing bacteria and yeasts, but experimental tests isolating their effects on wildflowers are largely lacking.

Chemical Fingerprint of Floral Nectar in Apple (Malus sp.) Cultivars Grown in Norway [PDF]
AntioxidantsThis study included the nectar of nine standard apple (Malus × domestica) cultivars (‘Red Aroma’, ‘Discovery’, ‘Summerred’, ‘Rubinstep’, ‘Elstar’, ‘Asfari’, ‘Eden’, ‘Fryd’, and ‘Katja’) and two crab apple (Malus sylvestris) cultivars (‘Dolgo’ and ...

Eco-evolutionary processes shaping floral nectar sugar composition [PDF]
Scientific ReportsFloral nectar sugar composition is assumed to reflect the nutritional demands and foraging behaviour of pollinators, but the relative contributions of evolutionary and abiotic factors to nectar sugar composition remain largely unknown across the ...

Nicotine in floral nectar pharmacologically influences bumblebee learning of floral features. [PDF]
Sci Rep, 2017 AbstractMany plants defend themselves against herbivores by chemical deterrents in their tissues and the presence of such substances in floral nectar means that pollinators often encounter them when foraging. The effect of such substances on the foraging behaviour of pollinators is poorly understood.
