Floral nectar reabsorption and a sugar concentration gradient in two long-spurred Habenaria species (Orchidaceae)
BackgroundFloral nectar is the most common reward flowers offered to pollinators. The quality and quantity of nectar produced by a plant species...

Floral nectar (FN): drivers of variability, causes, and consequences
This review article aims to compile updated information on the drivers of variability in floral nectar (FN), focusing mainly on concentration,...
-
Nectar tyramine decreases the duration of bumblebee visits on flowers
Several studies on floral nectar demonstrated that the behaviour of visit performed by pollinators is influenced by nectar chemistry. Biogenic amines...

Nectar secretion patterns are associated to nectar accessibility in a guild of crepuscular-nocturnal flowering plants
Floral morphology can determine the type of animal that can be an effective pollinator. In flowers with nocturnal anthesis long-tubed flowers may...

Nectar-Inhabiting Bacteria Affect Olfactory Responses of an Insect Parasitoid by Altering Nectar Odors
Floral nectar is ubiquitously colonized by a variety of microorganisms among which yeasts and bacteria are the most common. Microorganisms inhabiting...

Nectar characteristics of hummingbird-visited ornithophilous and non-ornithophilous flowers from Cerrado, Brazil
Hummingbirds in the Cerrado, the seasonal savannas in Central Brazil, visit both ornithophilous and non-ornithophilous flowers to collect nectar,...

Caffeine and ethanol in nectar interact with flower color impacting bumblebee behavior
AbstractCaffeine and ethanol are naturally occurring compounds in floral nectar. We examined how these compounds influenced pollinator behaviors...

Nectar concentrating behavior by bees (Hymenoptera: Anthophila)
Nectar is one of the most important resources used by bees. It has long been known that some bees concentrate nectar externally with their...

Floral attractants in an alpine environment: linking floral volatiles, flower size and pollinators
In high mountain environments, the availability of pollinators may decrease as elevation increases, affecting plant reproductive success. Floral...
