Dissertation Research: Phylogenetic Systematics and Evolutionary Ecology of Dioecious Figs and their Pollinators

9801259多诺霍系统发育和比较分析将被用来研究雌雄异株榕树(桑科：榕属亚种)之间相互作用的进化。以及传粉无花果小蜂(膜翅目：小蜂亚科)。来自野外的雌雄异株无花果和无花果黄蜂的配对收集是由魏布伦在1995-1997年间完成的。这些收集的形态和分子数据将用于平行的系统发育分析。无花果属植物核糖体DNA的内转录间隔区(ITS)和无花果黄蜂线粒体细胞色素氧化酶I(COI)的3‘端将被测序。荷兰莱顿国立博物馆van Natuurlijke历史馆的大量无花果黄蜂收藏品将被用来确认选定授粉物种的身份并探索形态特征。扫描电子显微镜将记录无花果和无花果黄蜂的形态特征，用于系统发育和比较分析。比较研究的目的是在系统发育的背景下评估共同进化假说，包括平行多样化和相互作用的谱系之间相互适应的情况。

9801259 Donoghue Phylogenetic and comparative analyses will be used to examine the evolution of interactions between dioecious figs (Moraceae: Ficus subg. Ficus) and their pollinating fig wasps (Hymenoptera: Agaoninae). Paired collections of dioecious figs and fig wasps from the field were made by Weiblen during 1995-1997. Morphological and molecular data from these collections will be used in parallel phylogenetic analyses. The internal transcribed spacer (ITS) region of nuclear ribosomal DNA from selected fig species and the 3' end of mitochondrial cytochrome oxidase I (COI) from fig wasps will be sequenced. The extensive fig wasp collections at the Rijksmuseum van Natuurlijke Historie, Leiden, The Netherlands, will be used to confirm the identities of selected pollinator species and to explore morphological characters. Scanning electron microscopy will document fig and fig wasp morphological characters used in phylogenetic and comparative analyses. Comparative studies are designed to evaluate coevolutionary hypotheses in a phylogenetic context, including parallel diversification and cases of reciprocal adaptations between interacting lineages.
