  1. Role of KNOX genes in the evolution and development of floral nectar spurs

    Box, Mathew S.University of Cambridge2010

    … produce new morphologies during evolution. The nectar spur is an evolutionarily labile structure known to influence speciation in a broad range of angiosperm taxa. Here, the genetic basis of nectar spur development, and the evolution of differences in nectar spur morphology, is investigated in …

  2. The Evolution and Development of Nectar Spurs

    Cullen, Erin, VictoriaUniversity of Cambridge2020

    Nectar spurs (tubular outgrowths of a floral organ which contain or give the appearance of containing nectar) are hypothesized to be a ‘key innovation’ which can lead to rapid speciation within a lineage, because they are involved in pollinator specificity. However, given that there are no …

  3. The Evolution and Development of Nectar Spurs

    Fisk, BenjaminUniversity of Cambridge2024

    Nectar spurs are tubular structures usually borne from perianth tissue, which contain, or appear to contain, a floral reward such as nectar or oil. Nectar spurs have convergently evolved in many disparate angiosperm lineages, often in association with long-proboscid pollinators. The spur provides a …

  5. Predicting Multi-trophic Consequences of an Emerging Disease

    Chupp, Adam D.2015

    … I monitored pollinator visitation and measured nectar spur lengths of P. ciliaris flowers and proboscis lengths of its floral visitors (at GBNERR). Papilio palamedes was the primary visitor (44 visits) but Phoebis sennae was also observed (4 visits). There were no significant differences among …
