Heat drastically alters floral color and pigment composition without affecting flower conspicuousness

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.

Inherited biotic protection in a Neotropical pioneer plant [PDF]

open access: yes, 2011
Chelonanthus alatus is a bat-pollinated, pioneer Gentianaceae that clusters in patches where still-standing, dried-out stems are interspersed among live individuals.

Flower trade-offs derived from nectar investment in female reproduction of two Nicotiana species (Solanaceae)

open access: yesActa Botânica Brasílica
Animal-pollinated flowers may orient resources for competing activities, such as nectar production for attracting flower visitors but then saving nectar (through inhibiting nectar production or by final resorption) for the subsequent maturation of fruits

Intraspecific Variation in Nectar Chemistry and Its Implications for Insect Visitors: The Case of the Medicinal Plant, Polemonium Caeruleum L.

open access: yesPlants, 2020
Floral nectar, being a primary reward for insect visitors, is a key factor in shaping plant–pollinator interactions. However, little is known about the variability in nectar traits, which could potentially affect pollinators and the reproduction of the ...

Nectar Production by Invasive Lantana camara and Endemic L. peduncularis in the Galápagos Islands [PDF]

open access: yes, 2012
Measurements of nectar volume and sugar concentration along two elevational gradients, in flower exclusion experiments, and over a diurnal cycle of nectar production, were compared for invasive Lantana camara and endemic Lantana peduncularis in the ...

Nectar Impact

open access: yes, 2016
Nectar Impact documents the work of the Nectar Virtual Laboratories, rich online environments that are built and led by the Australian research sector; and the Nectar Research Cloud, which provides computing infrastructure, software and services that allow Australia’s research community to store, access, and run data, remotely, rapidly and autonomously.

Floral specialization for beetle pollination and its implications for pollen dispersal in an African orchid

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Pollination by beetles is relatively rare in orchids, and this has been attributed to the clumsy behavior of beetles being unsuitable for the precise pollen transfer mechanisms that characterize the orchid family. We investigated floral specialization for beetle pollination in the rare fire‐dependent South African orchid Disa elegans ...

Quantifying Nectar Secretion Potential of Hygrophila auriculata (Schum.), Heine (Acanthaceae), and Salvia leucantha Cav. (Lamiaceae) for Honey Production

open access: yesAdvances in Agriculture, 2022
The study was conducted to quantify the nectar secretion dynamics, and honey production capacity of Hygrophila auriculata and Salvia leucantha. One day before nectar collection, a group of flowers was enclosed with mesh bags to measure accumulated nectar

Nectar Dynamics and Pollinators Preference in Sunflower

open access: yesInsects, 2022
Nectar is a complex biochemical substance secreted with particular rhythm by flower nectaries. Nectar is the base of a mutualism in which pollinators consume nectar, as food source, and are involuntarily responsible for the transport of pollen and ...

Modeling chronic periodontitis in rats: Persistent alveolar bone loss mediated by periodontal pathogens

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Irrigation of periodontal pockets with human periopathogens, in combination with a 14‐day ligature‐induced periodontitis protocol, significantly enhances alveolar bone loss and sustains bacterial colonization for up to 28 days following ligature removal, thereby more closely replicating the chronic nature of human periodontitis compared to the ligature
