The influence of pigmentation patterning on bumblebee foraging from flowers of Antirrhinum majus [PDF]

, 2013
Patterns of pigmentation overlying the petal vasculature are common in flowering plants,and have been postulated to play a role in pollinator attraction.

Indicators of Bioactivity and Floral Origin of New Zealand Honeys [PDF]

, 2009
The hypothesis that NIR might be capable of discriminating one floral source from another was explored. No prior analysis of NIR for New Zealand honeys has been reported.

Nectar

, 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

Sweet Scents: Nectar Specialist Yeasts Enhance Nectar Attraction of a Generalist Aphid Parasitoid Without Affecting Survival [PDF]

, 2018
Floral nectar is commonly inhabited by microorganisms, mostly yeasts and bacteria, which can have a strong impact on nectar chemistry and scent. Yet, little is known about the effects of nectar microbes on the behavior and survival of insects belonging ...

Laboratory studies examining aspects of scent marking, traplining and remote detection of reward in the foraging bumblebee. [PDF]

, 2007
PhDEnergy from food is essential for the survival of all animals. For decades, bumblebees have been used as model organisms for studying animal foraging strategies.

Fluorescent nectar in non-flying mammal-pollinated plants – observations and considerations in some Asparagaceae [PDF]

Plant Ecology and Evolution
Background and aims – Fluorescence is the emission of light by a fluorophore that has absorbed light of shorter wavelengths. While the role of fluorescence in visual communication has been documented in some animals (budgerigars, gelatinous zooplankton),

Effects of shading, fertilization, and irrigation on floral display and honey yield in Agastache rugosa in controlled pot culture

Frontiers in Plant Science
Sustainable cultivation of Agastache rugosa requires quantitative guidance on how to balance ornamental floral display with nectar-mediated honey production under realistic limitations in light, nutrients, and water.

Olfactory information use for foraging in "Microplitis mediator", a parasitoid of the cabbage moth "Mamestra brassicae" [PDF]

, 2013
My PhD project was at the interface between behavioural ecology and biological control, two disciplines that do not easily intertwine because of their divergent aims.

Nectar Robbery by Native and Invasive Bumblebees Reduces Floral Rewards but Not Seed Production in Desfontainia fulgens

Ecology and Evolution
Nectar robbery is common in hummingbird‐pollinated plants and is often assumed to reduce plant reproductive success by depleting floral rewards and disrupting pollination.

Native insect flower visitor diversity and feral honeybees on jarrah (Eucalyptus marginata) in Kings Park, an urban bushland remnant [PDF]

, 2005
This study aims to determine firstly the diversity of native insect visitors to flowers on the mass-flowering canopy tree jarrah (Eucalyptus marginata), and secondly the relative abundance of feral honeybees and native insects visiting jarrah flowers ...
