The influence of linear landscape features on pollinator behaviour
… both natural and artificial linear features on pollinator behaviour at medium and landscape scales. Observations along 30m transects, perpendicular to eight different hedgerows revealed that non-foraging pollinators were far more likely to exhibit linear flight next to the hedgerow than they …

Pollinator behaviour and the evolutionary genetics of petal surface texture in the Solanaceae
… trait across the angiosperms, and influence pollinator behaviour and pollination success. This work explores two key aspects of conical cell evolution: firstly, why conical cells are so prevalent across many diverse species, and secondly, why some species have lost conical petal cells. Using …

Petal cell shape and flower-pollinator interaction in Nicotiana
… epidermal cells may increase grip for insect pollinators and enhance flower colouration compared to non-conical cells. Nicotiana (Solanaceae) presents a diverse range of petal cell shapes. Interestingly, sister species in at least two phylogenetically distinct clades of the genus have …

Community ecology of small-mammal pollinated proteas
… was to determine whether there is a variation in pollinator efficiency of different animal species. Floral characteristics that may influence plantpollinator interactions were measured, including floral dimensions, nectar production and spectral reflectance. Live-trapping was conducted using …

Evolution in the genus Arum: a comparative analysis of morpohological and genetic variation.
… of isolation by distance, presumably a result of pollinator behaviour and seed dispersal. Leaf patterning in A. maculatum did not correspond to evolutionary lineages. However, similar leaf patterning characters in A. italicum are used to classify the two subspecies neglectum and italicum and the …
