Research on tropical plants and animals is especially important at this time because of the current high rates of destruction of tropical forests and the imminent extinction of many species that inhabit them. Dr. John Kress of the Marie Selby Botanical Gardens plans to study the South American species of the banana-relative Heliconia, a genus which includes the horticultural lobster-claw plants. Field collecting will be conducted in northern South America, to acquire living materials and preserved specimens. These will serve as the basis for study of macroscopic and microscopic features of the plants. Especially important will be investigations of pollen structure using the scanning electron microscope, in which Dr. Kress has already found distinctive patterns for many species. Information from morphology, geographic distributions, and habitats will be integrated into a comprehensive taxonomic treatment of the estimated 80 species of Heliconia that produce hanging or pendent inflorescences and their relatives. The study will improve understanding of tropical forest diversity and help in analyzing processes of speciation and evolution in tropical environments.

对热带植物和动物的研究尤其重要。 这一点很重要，因为目前的高利率 热带森林遭到破坏， 许多物种栖息于其中。 玛丽号的约翰·克雷斯博士 塞尔比植物园计划研究南美物种 香蕉相关的Heliconia，一个包括 园艺龙虾爪植物。 现场采集将 在南美洲北方进行，以获取生活材料 保存的标本。 这些将作为研究的基础 植物的宏观和微观特征。 尤其重要的是花粉结构的研究 使用扫描电子显微镜，克雷斯博士已经 已经发现了许多物种的独特模式。 从形态学、地理分布和 栖息地将被纳入一个全面的分类 处理估计80种的Heliconia， 悬挂的或悬垂的花序和它们的亲戚。 研究 将增进对热带森林多样性的了解， 在分析热带地区的物种形成和进化过程中， 环境.
