Distasteful Nectar Deters Floral Robbery [PDF]
Current Biology, 2017 Toxic nectar is an ecological paradox [1, 2]. Plants divert substantial resources to produce nectar that attracts pollinators [3], but toxins in this reward could disrupt the mutualism and reduce plant fitness [4]. Alternatively, such compounds could protect nectar from robbers [2], provided that they do not significantly alter pollinator visitation to

Can floral nectars reduce transmission of Leishmania? [PDF]
PLOS Neglected Tropical Diseases, 2021 ABSTRACT Insect-vectored Leishmania are the second-most debilitating of human parasites worldwide. Elucidation of the environmental factors that affect parasite transmission by vectors is essential to develop sustainable methods of parasite control that do not have off-target ...

The role of abiotic environmental conditions and herbivory in shaping bacterial community composition in floral nectar. [PDF]
PLoS ONE, 2014 Identifying the processes that drive community assembly has long been a central theme in ecology. For microorganisms, a traditional prevailing hypothesis states that "everything is everywhere, but the environment selects".

Nectar sugar production across floral phases in the Gynodioecious Protandrous Plant Geranium sylvaticum [corrected]. [PDF]
PLoS ONE, 2013 Many zoophilous plants attract their pollinators by offering nectar as a reward. In gynodioecious plants (i.e. populations are composed of female and hermaphrodite individuals) nectar production has been repeatedly reported to be larger in hermaphrodite ...

, 2021 Current models of floral nectar production do not include a contribution from photosynthesis by green nectary tissue, even though many species have green nectaries.

The Sensory and Cognitive Ecology of Nectar Robbing
Frontiers in Ecology and Evolution, 2021 Animals foraging from flowers must assess their environment and make critical decisions about which patches, plants, and flowers to exploit to obtain limiting resources. The cognitive ecology of plant-pollinator interactions explores not only the complex

Fertilizer and herbicide alter nectar and pollen quality with consequences for pollinator floral choices [PDF]
PeerJ, 2023 Background Pollinating insects provide economically and ecologically valuable services, but are threatened by a variety of anthropogenic changes. The availability and quality of floral resources may be affected by anthropogenic land use.

Ecological Solutions and Evidence, 2023 One of the main reasons why insect pollinators are declining is a lack of floral resources. In agricultural landscapes, remaining seminatural grasslands play a key role for providing such resources.

A dataset of nectar sugar production for flowering plants found in urban green spaces
Ecological Solutions and Evidence, 2023 Nectar and pollen are floral resources that provide food for insect pollinators, so quantifying their supplies can help us to understand and mitigate pollinator declines.

Nicotine in floral nectar pharmacologically influences bumblebee learning of floral features [PDF]
Scientific Reports, 2017 AbstractMany plants defend themselves against herbivores by chemical deterrents in their tissues and the presence of such substances in floral nectar means that pollinators often encounter them when foraging. The effect of such substances on the foraging behaviour of pollinators is poorly understood.
