Interpopulation variation in nectar production in Aconitum columbianum (Ranunculaceae)

Oecologia, 1980
In Aconitum columbianum there are extreme interpopulation differences in rates of nectar secretion per flower. Since nectar sugar concentration varies little among populations, increased nectar secretion results in a greater mass of sugar per flower for pollinator attraction. These differences in the amount of reward offered per flower account at least

Factors affecting nectar sugar composition in chiropterophilic plants

Revista Mexicana de Biodiversidad, 2016
Most pollinators prefer the sugars present in the nectar they consume, so it has been hypothesized that they have molded nectar trait evolution. However, nectar-feeding bats do not exhibit preferences for the sugars present in their diet. We analyzed the

The Patterns of Intraspecific Variations in Mass of Nectar Sugar along a Phylogeny Distinguish Native from Non-Native Plants in Urban Greenspaces in Southern England

Plants, 2023
To serve human needs, non-native species are selected based on an array of functional traits, which generally confer competitive advantages to these species in their recipient environments. Identifying non-obvious functional traits that indirectly inform

Producción de néctar en matorrales del sur de España: (Andalucía) [PDF]

, 1995
Nectar production in scrubland of southern Spain (Andalusia). The aim of this work is to evaluate the alimentary resources for the Apis mellifera. A study has been carried out about the nectar production of the most representative species of a scrubland ...

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

Advanced Science, EarlyView.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

CMOS‐Integrated Synaptic Photoreceptor Chip Inspired by Insect Visual Processing

Advanced Science, EarlyView.
CMOS‐integrated Si QDs/ReS2 synaptic photoreceptor array mimics the parallel processing and wavelength‐selective strategy of insect vision. By combining intrinsic ultraviolet‐violet sensitivity with synaptic plasticity, the chip enables frontend sensory redundancy reduction without external filters, offering a scalable pathway toward lowpower ...

Warming temperatures affect meadow‐wide nectar resources, with implications for plant–pollinator communities

Ecosphere, 2022
Nectar production may be a point of sensitivity that can help link primary and secondary trophic responses to climate shifts, and is therefore important to our understanding of ecosystem responses.

NECTAR PRODUCTIVITY OF SUNFLOWER LINES AND HYBRIDS

Сборник материалов 11-й Всероссийской конференции молодых учёных и специалистов «Актуальные вопросы биологии, селекции, технологии возделывания и переработки сельскохозяйственных культур», 2021
Common sunflower is an entomophilous crop; therefore, the presence of pollinating insects is necessary for the realization of the potential productivity of plants. Nectar is the main attractant of sunflower. In this work we determined the nectar bearing capacity and sugar content (dry matter content) of nectar in tubular flowers of various sunflower ...

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.

Evaluating the African arid corridor hypothesis: A meta‐analysis including the phylogenetic and biogeographical history of Sesamothamnus

American Journal of Botany, EarlyView.
Abstract Premise We examined the African arid corridor (AAC) disjunction pattern of vascular plants between northeastern and southwestern Africa in the context of geological and climatic events since the late Miocene. We developed a phylogenetic and biogeographical framework for the arid‐adapted genus Sesamothamnus (Pedaliaceae), a classic example of ...
