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 ...

Bee pollen as functional food and environmental bioindicator: current evidence and future challenges

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Bee pollen (BP), a plant‐derived product collected by honey bees, is increasingly promoted as a functional food due to its content of proteins, essential amino acids, lipids, vitamins, minerals, and bioactive compounds such as polyphenols and flavonoids.

Area‐restricted search under realistic constraints

Oikos, EarlyView.
Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

Sweet Scents: Nectar Specialist Yeasts Enhance Nectar Attraction of a Generalist Aphid Parasitoid Without Affecting Survival

Frontiers in Plant Science, 2018
Floral nectar is commonly inhabited by microorganisms, mostly yeasts and bacteria, which can have a strong impact on nectar chemistry and scent. Yet, little is known about the effects of nectar microbes on the behavior and survival of insects belonging ...

A plant–pollinator invasional meltdown: the Japanese pagoda tree Styphnolobium japonicum facilitates the invasion of the giant resin bee Megachile sculpturalis

Oikos, EarlyView.
An invasional meltdown can occur when a non‐native species facilitates the spread of another non‐native species in the invaded area, increasing its likelihood of survival or its ecological impact. Plant–pollinator systems pose an exceptional study system to test this concept, which remains poorly known.

Nectary Structure and Nectar Secretion Characteristics Among Various Cultivars of Paeonia lactiflora

Plants
Background: Paeonia lactiflora Pall. produces substantial quantities of nectar during the bud stage. In the production of cut flowers, this nectar attracts contaminants that compromise the quality of the flowers.

Demonstrating limitations of area‐restricted search as a foraging mechanism

Oikos, EarlyView.
Foragers often rely on simple behavioral rules that translate local environmental cues into movement decisions. One of the most widespread rules is area‐restricted search (ARS), in which movement becomes less directional following resource encounters. ARS is generally considered effective for exploiting clustered resources, yet recent conceptual work ...

The potential effect of megafaunal extinctions on modern conservation of horse chestnut Aesculus hippocastanum

PLANTS, PEOPLE, PLANET, EarlyView.
Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

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.

The Octadecanoid Pathway, but Not COI1, Is Required for Nectar Secretion in Arabidopsis thaliana

Frontiers in Plant Science, 2018
Over 75% of crop species produce nectar and are dependent on pollinators to achieve maximum seed set, yet little is known about the mechanisms regulating nectar secretion.
