Spatial Relation of Bumblebees (Hymenoptera-Apidae) with Host-Plant and their Conservation Issues: An Outlook from Urban Ecosystem of Kathmandu Valley, Nepal [PDF]
, 2019 Ecology and conservation status of bumblebee species remains poorly understood, especially in rapidly degrading urban ecosystems, which is important considering the role of bumblebees in the pollinations. We collected more than 200 bumblebee (Bombus

Honey volatiles as a fingerprint for botanical origin: a review on their occurrence on monofloral honeys [PDF]
, 2020 Honeys have specific organoleptic characteristics, with nutritional and health benefits, being highly appreciated by consumers, not only in food but also in the pharmaceutical and cosmetic industries. Honey composition varies between regions according to

Chronic intake of fermented floral nectar by wild treeshrews [PDF]
Proceedings of the National Academy of Sciences, 2008 For humans alcohol consumption often has devastating consequences. Wild mammals may also be behaviorally and physiologically challenged by alcohol in their food. Here, we provide a detailed account of chronic alcohol intake by mammals as part of a coevolved relationship with a plant.

Frontiers in Ecology and Evolution, 2018 Most pollinators visit flowers in the search of nectar rewards. However, as the floral nectar can often not be directly detected by pollinators, many flower visitors use secondary metabolites such as odor- or taste-proxies to anticipate nectar quantity ...

Floral abundance and resource quality influence pollinator choice [PDF]
, 2016 1. Pollinator declines caused by forage habitat loss threaten insect pollination services. Pollinating insects depend on adequate floral resources, and their ability to track these resources.

The Campsis-Icterus association as a model system for avian nectar-robbery studies
Scientific Reports, 2022 Avian nectar-robbing is common in some floras but its impact on plant-pollinator mutualisms, flowering phenology, and the evolution of floral traits remains largely unexplored.

Nectar-dwelling microbes of common tansy are attractive to its mosquito pollinator, Culex pipiens L.
BMC Ecology and Evolution, 2021 Background There is widespread interkingdom signalling between insects and microbes. For example, microbes found in floral nectar may modify its nutritional composition and produce odorants that alter the floral odor bouquet which may attract insect ...

Cognition-mediated evolution of low-quality floral nectars
Science, 2017 Sweet, but not too sweet Nectar-feeding pollinators, when given a choice, tend to prefer nectar with high concentrations of sugar. Nectar-producing plants, however, tend to produce more dilute nectar. This mismatch between selective force and trait value has long been seen as an evolutionary paradox. Nachev et al.
