2. Identify Pollination Agents: - The agents of pollination can include wind, water, and insects. Each of these agents plays a significant role in the transfer of pollen. 3. Examples of Wind-Pollinated Flowers: - Wind-pollinated flowers typically have lightweight pollen that can be easily...
Market System Dynamics (MSD) and Constructivist Market Studies (CMS) have both emerged to return markets to the center of marketing thought. Arguing that the two fields have only rarely engaged in intellectual exchange, we compare MSD and CMS and consider the potential for their cross-pollination...
The presence of pollen limitation but not dispersal limitation, despite both services depending on the same bird, is influenced by the much faster rates of flower ripening per day compared with fruit ripening (1554 times faster in P. tetrapetala). In New Zealand, pollination failure probably ...
partnership dialogues, and responsiveness to the changing context. In the case of medical financial assistance, the dynamic was characterized by long-term commitment to addressing local needs, on-site mutual learning and understanding
This study views sustainability after the exit of development assistance for health (DAH) as a shared responsibility between donors and recipients and sees transitioning DAH-supported interventions into domestic health policy as a pathway to this sustainability. It aims to uncover and understand the re...
Explain the different types of pollination. List two agents of pollination. How does suitable pollination lead to fertilization? View Solution Explain how is velocity different from speed. View Solution Define a nerve and explain the three different kinds. View Solution Define the term inflorescence...
In her doctoral thesis at Columbia University, entitled "Nineteenth Century American Flower Painting and the Botanical Sciences" (1979, pp 308-311), Forshay comments on Darwin's interest in orchid pollination but correctly notes that "Darwin did not recognize that any orchid species were pollinate...
Gene flow and polyploidy have been found to be important in Juniperus evolution. However, little evidence has been published elucidating the association of both phenomena in juniper taxa in the wild. Two main areas were studied in Spain (Eastern Iberian
pollination efficiencypollinator attractionpollinator‐mediated selectionIdentifying traits and agents of selection involved in local adaptation is important for understanding population divergence. In southern Sweden, the moth‐pollinated orchid Platanthera bifolia occurs as a woodland and a grassland ecotype ...
During the day, they are visited by species of Hesperiidae (Lepidoptera), which remove the pollinia. The flowers of E. orchidiflorum open at night, are green with nuptial and extranuptial nectaries, and have a strong odour at night, suggesting nocturnal pollination agents, possibly moths. To...
