Extrafloral-nectar-based partner manipulation in plant–ant relationships [PDF]

AoB PLANTS, 2015
Plant-ant interactions are generally considered as mutualisms, with both parties gaining benefits from the association. It has recently emerged that some of these mutualistic associations have, however, evolved towards other forms of relationships and, in particular, that plants may manipulate their partner ants to make reciprocation more beneficial ...

Is bacterial microbiome from the Polemonium caeruleum L. (Polemoniaceae) nectar geographically variable?

Acta Societatis Botanicorum Poloniae, 2019
Floral nectar is one of the key rewards in the mutualistic interactions between plants and pollinators. However, there is a growing amount of evidence that shows that another group of organisms may be involved in the pollination process, namely the ...

Catching the thief: Nectar robbing behaviour by bumblebees on naturalised Fuchsia magellanica in Ireland

Journal of Pollination Ecology, 2021
Fuchsia magellanica (Ongaraceae) is a plant with a traditionally ornithopholous pollination system, pollinated primarily by hummingbirds in its native range. As a naturalised alien plant in Ireland, F.

Differential Effects of Climate Warming on the Nectar Secretion of Early- and Late-Flowering Mediterranean Plants

Frontiers in Plant Science, 2018
Floral nectar is a vital resource for pollinators, thus having a very important role in ecosystem functioning. Ongoing climate warming could have a negative effect on nectar secretion, particularly in the Mediterranean, where a strong temperature rise is

Differences in Nectar Traits between Ornithophilous and Entomophilous Plants on Mount Cameroon

Plants, 2021
Despite a growing number of studies, the role of pollinators as a selection agent for nectar traits remains unclear. Moreover, the lack of data from some biogeographic regions prohibits us from determining their general importance and global patterns. We

Plant protection product residues in plant pollen and nectar: A review of current knowledge

Environmental Research, 2020
Exposure to Plant Protection Products, PPPs, (fungicides, herbicides and insecticides) is a significant stressor for bees and other pollinators, and has recently been the focus of intensive debate and research. Specifically, exposure through contaminated pollen and nectar is considered pivotal, as it presents the highest risk of PPP exposure across all

Floral nectar microbial communities exhibit seasonal shifts associated with extreme heat: Potential implications for climate change and plant-pollinator interactions

Frontiers in Microbiology, 2022
Floral nectar contains vital nutrients for pollinators, including sugars, amino acids, proteins, and secondary compounds. As pollinators forage, they inoculate nectar with bacteria and fungi.

Eco-evolutionary processes shaping floral nectar sugar composition

Scientific Reports
Floral nectar sugar composition is assumed to reflect the nutritional demands and foraging behaviour of pollinators, but the relative contributions of evolutionary and abiotic factors to nectar sugar composition remain largely unknown across the ...

Sodium‐enriched nectar shapes plant–pollinator interactions in a subalpine meadow

Ecology and Evolution
Many plants have evolved nutrient rewards to attract pollinators to flowers, but most research has focused on the sugar content of floral nectar resources.

Pollen Analysis of Bees’ Crop Nectar as an Effective Method to Determine Nectar Sources: Comparison with Traditional Approaches

Applied Biosciences
Identifying the nectar sources of stingless bees is essential for understanding plant–pollinator interactions and for promoting sustainable meliponiculture.
