Soft Lithography Using Nectar Droplets [PDF]

open access: yesLangmuir, 2015
In spite of significant advances in replication technologies, methods to produce well-defined three dimensional structures are still at its infancy. Such a limitation would be evident if we were to produce a large array of simple and, especially, compound convex lenses, also guaranteeing that their surfaces would be molecularly smooth.

Distasteful Nectar Deters Floral Robbery [PDF]

open access: yesCurrent Biology, 2017
Toxic nectar is an ecological paradox [1, 2]. Plants divert substantial resources to produce nectar that attracts pollinators [3], but toxins in this reward could disrupt the mutualism and reduce plant fitness [4]. Alternatively, such compounds could protect nectar from robbers [2], provided that they do not significantly alter pollinator visitation to

Physiological barriers to oral intake in survivors of critical illness: A scoping review

open access: yesNutrition in Clinical Practice, EarlyView.
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.

Do Flowers Reabsorb Nectar?

open access: yesFunctional Ecology, 1991
The rate of change in the standing crop of nectar allowed to accumulate in flowers, described here as the apparent secretion rate, can be resolved into two components: gross secretion rate and apparent reabsorption rate. A simple model shows how changes in these component rates may affect the apparent secretion rate.

Differences in reproductive performance traits of two Platanthera species

open access: yesNordic Journal of Botany, EarlyView.
The species Platanthera bifolia and P. chlorantha (Orchidaceae) are both declining in Europe, but P. bifolia has been diminishing relatively more. Loss of habitats and landscape heterogeneity due to agricultural intensification or abandonment of less fertile areas are primary drivers of decreasing orchid populations.
