9311727 Kornfield This research involves a detailed phylogenetic and biogeographic study of endemic killifishes of Lake Titicaca in South America. The experimental approach will entail extensive collecting in the lake followed by a detailed genetic analysis of mitochondrial DNA sequence variation within and among species. These genetic data will be used to both construct a phylogeny for the these endemic fishes and examine population and historical processes related to this unusual diversification in this South American lake. %%% This investigation will provide a detailed assessment of the various processes (both biotic and abiotic) responsible for the diversity of endemic (unique) killifishes seen in Lake Titicaca. Investigations of the genetic uniqueness of isolated populations of killifish will facilitate the formulation of conservation policies optimized for preservation of the biotic diversity of this rare and unusual fish fauna. This is important as the entire Andean Altiplano ecosystem is becoming threatened by increased human activities. ***

小行星9311727 这项研究涉及南美洲的的喀喀湖特有的鳉鱼的详细系统发育和鱼类地理学研究。 实验方法将需要在湖中进行广泛的收集，然后对物种内和物种间的线粒体DNA序列变异进行详细的遗传分析。 这些遗传数据将用于构建这些特有鱼类的遗传学，并研究与这个南美湖泊中这种不寻常的多样化有关的人口和历史过程。 这项调查将提供一个详细的评估的各种过程（生物和非生物）负责的喀喀湖特有的（独特的）鳉鱼的多样性。 调查的遗传独特性的孤立群体的？ 这一点很重要，因为整个安第斯高原生态系统正受到人类活动增加的威胁。 ***
