Dissertation Research: The Pollination Ecology of Calyptrogyne sarapiquensis

花的展示可以在相同的植物和动物之间变化 物种，这种变化可能会影响繁殖成功。 显示可能会有所不同，在他们的能力，以吸引传粉者， 它们对破坏性食花动物的吸引力。 我将研究如何 花展示的变化影响传粉者的访问， Calyptorgyne sarapiquensis的食花动物，雨林林下植物 手掌 尽管一些花很可能已经进化到 最大限度地长期繁殖成功，植物很少设置结果 从所有雌花中分离出来 水果集可能会减少许多 因素，包括缺乏授粉，花朵的捕食， 缺乏发展水果的资源。 在第一场比赛中，我 将研究这些因素的自然变化水平， 把它们和地里的果实数量联系起来。 这些相关 数据将被用来设计第二个操纵实验 田野季节 这些实验将考虑的相互作用， 决定坐果的因素 植物也能实现繁殖 成功传播花粉。 花粉传播的距离 会影响植物繁殖的关键因素 生态学，如未来配偶的数量，可用性 花粉的雌性，交配人口的大小和 它覆盖的区域。 我将通过追踪花粉的运动 花粉类似物。

Floral display can vary between plants and animals of the same species, and this variation can affect reproductive success. Displays may vary in their capacity to attract pollinators, and in their attraction to destructive florivores. I will examine how the variation in floral display affects visitation by pollinators and florivores of Calyptorgyne sarapiquensis, a rain forest understory palm. Although a number of flowers may well have evolved to maximize long-term reproductive success, plants rarely set fruit from all of their female flowers. Fruit set may be reduced by many factors, including lack of pollination, predation of flowers, and lack of resources to develop fruit. In the first field season I will examine the natural levels of variation in these factors and relate them to amount of fruit set in the field. These correlative data will be used to design manipulative experiments for the second field season. These experiments will consider the interaction of factors determining fruit set. Plants also achieve reproductive success by dispersing their pollen. The distance over which pollen is moved influences key elements of the plant's reproductive ecology, such as the number of prospective mates, the availability of pollen for females, the size of the mating population and the area it covers. I will examine pollen flow by tracing the movement of a pollen analog.
