Floral nectar reabsorption and a sugar concentration gradient in two long-spurred Habenaria species (Orchidaceae)

BMC Plant Biology, 2023
Background Floral nectar is the most common reward flowers offered to pollinators. The quality and quantity of nectar produced by a plant species provide a key to understanding its interactions with pollinators and predicting rates of reproductive ...

Kin discrimination in plants: overview and implications for population and community ecology

Biological Reviews, EarlyView.
ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...

Potential of Bee Pollen as a Nutraceutical And/Or Functional Ingredient for Metabolic Syndrome Management: In Vitro Antioxidant, Anti‐Inflammatory, and Digestive Enzyme Inhibitory Activities

Food Chemistry International, EarlyView.
Bee pollen samples from China and Spain exhibited in vitro antioxidant, anti‐inflammatory, and digestive enzyme inhibitory activities due to their composition, suggesting their potential as a nutraceutical or functional ingredient to help counteract oxidative stress, chronic inflammation, and metabolic disorders.

Nectar as food for birds: The physiological consequences of drinking dilute sugar solutions [PDF]

, 2003
Nectarivory has evolved many times in birds: although best known in hummingbirds, sunbirds and honeyeaters, it also occurs on an opportunistic basis in a varied assortment of birds. We present a phylogenetic analysis of the distribution of nectarivory in

Nectar secretion rate.

, 2013
While proboscis length diverges for all values of nectar secretion rate (triangles), divergence of corolla- -tube depth is only observed for low and intermediate values of nectar secretion rate (circles).

Effect of Abiotic Factors on Nectar Quality and Secretion of Two Early Spring Species, Galanthus nivalis L. and Helleborus niger L.

Diversity
Floral nectar is mainly a reward in the form of food for pollinators. In early spring, when snow can still be present, pollinators have trouble finding food.

Dietary management and feeding considerations of pediatric aerodigestive and upper gastrointestinal motility disorders: A position paper by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) Neurogastroenterology and Motility Committee

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objective Pediatric aerodigestive and upper gastrointestinal (UGI) motility disorders are common and may be associated with compromised nutritional status and decreased quality of life. Traditional dietary recommendations for aerodigestive and UGI motility disorders have been rudimentary and largely based upon experience and common sense ...

Is there a diel pattern to nectar secretion in the Red Bloodwood Corymbia gummifera? [PDF]

, 2013
Nectar secretion was measured at 6-h intervals over a 24-h period in flowers of the Red Bloodwood, Corymbia gummifera (family Myrtaceae). Secretion varied among time periods and among trees. There was no clear diurnal or nocturnal pattern.
