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

open access: yesFrontiers 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.

Nectar chemistry modulates the impact of an invasive plant on native pollinators [PDF]

open access: yesFunctional Ecology, 2015
Summary Invasive species are considered a main driver of pollinator declines, yet the direct effects of invasive alien plants on pollinators are poorly understood. Abundant, invasive plant species can provide a copious nectar resource for native pollinators.

Nectar-living yeasts of a tropical host plant community: diversity and effects on community-wide floral nectar traits [PDF]

open access: yesPeerJ, 2017
We characterize the diversity of nectar-living yeasts of a tropical host plant community at different hierarchical sampling levels, measure the associations between yeasts and nectariferous plants, and measure the effect of yeasts on nectar traits. Using

Agri-environment nectar chemistry suppresses parasite social epidemiology in an important pollinator [PDF]

open access: yes, 2021
Emergent infectious diseases are a principal driver of biodiversity loss globally. The population and range declines of a suite of North American bumblebees, a group of important pollinators, have been linked to emergent infection with the microsporidian Nosema bombi .

Nectar chemistry is tailored for both attraction of mutualists and protection from exploiters [PDF]

open access: yesPlant Signaling & Behavior, 2009
Plants produce nectar to attract pollinators in the case of floral nectar (FN) and defenders in the case of extrafloral nectar (EFN). Whereas nectars must function in the context of plant-animal mutualisms, their chemical composition makes them also attractive for non-mutualistic, exploiting organisms: nectar robbers and nectar-infesting microorganisms.

Free amino acids in nectar: its composition and variability among bat-pollinated plants

open access: yesRevista Mexicana de Biodiversidad, 2021
Regardless of the low concentrations at which amino acids are present in floral nectar of bat-pollinated plants, their role as nectar flavor providers and their influence on bats’ foraging decisions have been recognized.

Phenology and foraging bias contribute to sex‐specific foraging patterns in the rare declining butterfly Argynnis idalia idalia

open access: yesEcology and Evolution, 2023
Variation in pollinator foraging behavior can influence pollination effectiveness, community diversity, and plant–pollinator network structure. Although effects of interspecific variation have been widely documented, studies of intraspecific variation in

Honey bees avoid nectar colonized by three bacterial species, but not by a yeast species, isolated from the bee gut. [PDF]

open access: yesPLoS ONE, 2014
The gut microflora of the honey bee, Apis mellifera, is receiving increasing attention as a potential determinant of the bees' health and their efficacy as pollinators. Studies have focused primarily on the microbial taxa that appear numerically dominant
