Efekt zkušeností a květních vlastností na projev preferencí a věrnosti u Eristalis tenax
… over its lifetime based on experience with the flowers they have visited. Very few studies have examined the effect of experience on preferences and especially constancy in relation to multiple floral traits in hoverflies (Syrphidae, Diptera), which are an important pollinator group. In this …

Understanding the development, evolution, and function of bullseye pigmentation patterns in Hibiscus trionum
… were found to discriminate between, and prefer, artificial flowers with H.trionum-like bullseye patterns to H.richardsonii-like bullseye patterns.

Petal cell shape and flower-pollinator interaction in Nicotiana
… petal cell shape interact in the perception of flowers by model pollinator Bombus terrestris using biomimetic artificial flowers. Pollinator behaviour experiments indicate that the bumblebees can discriminate flowers with conical from flowers with non-conical surfaces, on a red and on a white …

From Hand Craft to Digital Technology: a practice-based material culture analysis of the historical and contemporary ancillary trades of the London élite fashion industry
… scale, bespoke manufacturing of items such as artificial flowers and buttons; and the provision of specialist finishes such as bead-work, embroidery and pleating. These trades have developed little over the last century or more and most still involve varying degrees of skilled hand-making …

Grip, slip, petals, and pollinators: Linking the biomechanics, behaviour and ecology of interactions between bees and plants
… importance for the interactions between bees and flowers. In this thesis, I explore the biomechanics of attachment and morphological diversity of bee attachment devices, linking this to the behavioural ecology of bee interactions with flowers. Attachment devices come in two main kinds: claws or …

Petals, pigments and pollinator preferences
… bee behaviour laboratory, I have used plastic artificial ‘flowers’ and lab colonies of bumblebees to test bee responses to the limits of observed variation in shape, in terms of recognition and finding speed, and found that more stellated flower outlines result in a small but non-significant …

Sensory Ecology of Foraging in Bumblebees
… processes that constrain the search for flowers. I measured search time for artificial flowers of various sizes and colors, a key variable defining the value of a prey type in optimal foraging theory. When flowers were large, search times correlate well with the color contrast of the …
