nectar

, 2017
To establish if foliar herbivory causes changes in floral rewards that could alter floral visitation, we selected another 30 pairs of plants (15 pin and 15 thrum) of P. angustifolia. On each pair, we selected branches with inflorescences at the bud stage

Kin discrimination in plants: overview and implications for population and community ecology

Biological Reviews, EarlyView.
ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...

Nectar Production and Three Main Sugars in Nectar of Salvia pratensis and Salvia glutinosa in Correlation with Abiotic Factors

Agriculture
Floral nectar is mainly a reward in the form of food for pollinators. Its composition plays an important role when pollinators choose their food. Several studies have shown that the popularity of flowers with nectar is influenced by the concentration and

Land birds on atolls: diversity, origin, and function

Biological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Diurnal nectar secretion dynamics in Roscoea cautleoides (Zingiberaceae) reveal the role of non-sugar chemicals in plant–pollinator interaction

Current Plant Biology
Floral nectar is essential for plant-pollinator interactions, directly influencing plant reproduction. Although the composition of nectar has been widely studied, the daily dynamics of non-sugar components in the nectar remain unknown.

It Is Not All about Being Sweet: Differences in Floral Traits and Insect Visitation among Hybrid Carrot Cultivars

Insects, 2020
Cytoplasmically male-sterile (CMS) carrot cultivars suffer from low pollination rates. In this study, insect visitation varied more than eightfold between 17 CMS carrot cultivars in a field-based cultivar evaluation trial.

Responsible Leadership for Sustainable Agritourism: A Multilevel Causal Mechanism Analysis and the Facilitating Roles of Social Capital

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the causal mechanisms by which responsible leadership (RL) promotes sustainable agritourism development in the Mekong Delta, Vietnam. Using focus groups and multiple case studies across five exemplary agritourism operations, we examine how RL operates across multiple levels to influence sustainable agritourism outcomes.

Among-population variation in microbial community structure in the floral nectar of the bee-pollinated forest herb Pulmonaria officinalis L.

PLoS ONE, 2013
BackgroundMicrobial communities in floral nectar have been shown to be characterized by low levels of species diversity, yet little is known about among-plant population variation in microbial community composition.Methodology/principal findingsWe ...

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

PeerJ, 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

, 2013
Total nectar sugar produced by H. virgata flowerheads in 1 x 1 m plots of varying floral densities at the sites and dates used in Visitation.csv. Flowerheads were bagged in the morning before insects became active and nectar measured in the late morning
