Physiological barriers to oral intake in survivors of critical illness: A scoping review
Nutrition in Clinical Practice, Volume 41, Issue 2, Page 461-485, April 2026.Abstract Oral nutrition is the predominant mode of nutrition delivery on the post–Intensive Care Unit (ICU) ward; yet, it is associated with lower intake than via enteral or parenteral nutrition. There are limited data on barriers that influence oral intake in ICU survivors.

Oikos, Volume 2026, Issue 4, April 2026.Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.

The ecological and evolutionary importance of nectar‐secreting galls [PDF]
Ecosphere, 2019 AbstractSome species of cynipid wasp engage in mutualisms with ants by producing nectar‐secreting galls, providing carbohydrates, and receiving protection from parasitoids. The galls are functionally similar to extrafloral nectaries, plant structures well known for their role in ant–plant mutualisms.

Ecological Entomology, Volume 51, Issue 2, Page 395-404, April 2026.Extrafloral nectar mediates interactions among plants, ants and herbivores; its contingency on damage amount and within‐plant uniformity is poorly understood. Here, we explore these factors in wild cotton (Gossypium hirsutum). Herbivory amount drove increases in extrafloral nectar induction per nectary, whereas within‐plant variability in damage ...

The beast initiate: the lycanthropy of Heracles [PDF]
, 2019 The obscurantist Hellenistic poet Lycophron referenced the initiation of Heracles as a beast suckling the breast of the goddess Hera. This was the event that was the mythological origin of the Galaxy and of the lily flower that incarnated the same ...

Nectar secretion in the flowers of comfrey (Symphytum officinale L.) and nectar chemistry
Acta Agrobotanica, 2013 Nectar secretion and nectar chemistry in the flowers of comfrey (<i>Symphytum officinale</i> L.) were examined in the four stages of anthesis: large buds, before pollen exposure: II - freshy opened flowers with the beginning of anther dehiscence: III- completely opened flowers in the maximum of pollen exposure: lV- flowers at the final ...

The Floral Nectary ofDigitalis purpureaL., Structure and Nectar Secretion [PDF]
Annals of Botany, 1998 Abstract The floral nectary of the foxglove (Digitalis purpureaL.), located at the base of the ovary, was examined by: scanning electron microscopy; quantitative bright-field microscopy via computer-aided 3-D reconstruction from serial sections; morphometric procedures; transmission electron microscopy and measurement of nectar efflux under different

Continuous and discontinuous nectar secretion in some pear cultivars
International Journal of Horticultural Science, 2000 Hourly nectar secretion was studied in five pear cultivars between 1997-1999. Some cultivars (e.g. ‘Csákvári téli') secreted nectar continuously during the whole day, offering both nectar and pollen for pollinating insects. Discontinuous secretion (e.g. cvs. ‘Viki', `Nyárig tartó 6/19') is less advantageous from the viewpoint of insect attraction.

Distribution, structural and ecological aspects of the unusual leaf nectaries of Calolisianthus species (Gentianaceae) [PDF]
, 2011 Nectaries in leaves of Gentianaceae have been poorly studied. The present study aims to describe the distribution, anatomy, and ecological aspects of extrafloral nectaries (EFNs) of three Calolisianthusspecies and in particular the ultrastructure of EFNs
