Mutualism and Antagonism in a Post‐Extinction Hawaiian Bird–Lobelioid Pollination System

open access: yesEcology and Evolution
Extinction of specialized pollinators can alter the balance between mutualism and antagonism in plant–animal interactions, yet the mechanistic consequences of partner loss remain poorly resolved. We examined plant–bird interactions among three endangered

Floral trait variation across individual plants within a population enhances defense capability to nectar robbing

open access: yesPlant Diversity, 2023
Floral trait variation may help pollinators and nectar robbers identify their target plants and, thus, lead to differential selection pressure for defense capability against floral antagonists.

Florivory and Pollination Intersection: Changes in Floral Trait Expression Do Not Discourage Hummingbird Pollination

open access: yesFrontiers in Plant Science, 2022
Many flowers are fed on by florivores, but we know little about if and how feeding on flowers affects their visual and chemical advertisement and nectar resource, which could disrupt pollination.

Distasteful Nectar Deters Floral Robbery [PDF]

open access: yesCurrent 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

Nectar biosynthesis is conserved among floral and extrafloral nectaries [PDF]

open access: yesPlant Physiology, 2021
AbstractNectar is a primary reward mediating plant–animal mutualisms to improve plant fitness and reproductive success. Four distinct trichomatic nectaries develop in cotton (Gossypium hirsutum), one floral and three extrafloral, and the nectars they secrete serve different purposes.

The role of abiotic environmental conditions and herbivory in shaping bacterial community composition in floral nectar. [PDF]

open access: yesPLoS 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]

open access: yesPLoS 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 ...

Floral resources in Swedish grasslands remain relatively stable under an experimental drought and are enhanced by soil amendments if regularly mown

open access: yesEcological 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.

The Sensory and Cognitive Ecology of Nectar Robbing

open access: yesFrontiers 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
