Vi Ngo Bio 100LW, Wed. 1-3:50pm TA: Daniela Bruckman Writing Assignment #2: Annotation Aphelandra acanthus , a shrub species, was studied in order to determine how well bats and hummingbirds act as pollinators and how they contribute to the overall pollination scheme of A. acanthus . The methods of examining the species’ phenology and determining the number of visits each pollinator makes to the species (pollinator “quantity”) and the amount of pollen the pollinators leave behind (pollinator “quality”) were performed. The data was analyzed by observing the characteristics of A. acanthus , calculating each pollinator’s visitation rates, and analyzing the amount of pollen collected on tape samples. In conclusion, bats are A. acanthus ’s primary pollinators and hummingbirds are their secondary pollinators because bats have a more effective pollinator “quality.” Muchhala, N., Caiza, A., Vizuete, J.C., Thomson, J.D. 2009. A generalized pollination system in the tropics: bats, birds, and Aphelandra acanthus .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
