In extension of a previous project dedicated to study the genetic diversity of the so-called Tugai forests in the extremely arid Tarim basin of Chinas Xinjiang province, we want to investigate reproductive biology and the performance of sexes in Populus euphratica, as well as the gene flow between stands to explain the high degree of genetic diversity distributed within stands. This should allow deriving sound recommendations for a conservation strategy of the Tugai forests. In addition, we want to extent the existing body of data on mapped and genotyped old-growth stands to derive a sex aggregation index and show its usefulness for estimating stand clonality by comparison with the clonality index derived from microsatellite genotyping. Due to a change of methods for genotyping (from AFLP to a high-throughput microsatellite multiplex PCR) we saved money to genotype three more stands. This will provide consumables for one Ph.D. student (currently payed by a scholarship from the state of Mecklenburg-Western Pomerania) to complete her Ph.D. thesis.

在以前的项目致力于研究中国新疆极端干旱的塔里木盆地所谓的土改森林的遗传多样性的延伸，我们想调查胡杨的生殖生物学和性别的表现，以及林分之间的基因流动，以解释林分内分布的高度遗传多样性。这将有助于为Tugai森林的保护战略提出合理的建议。此外，我们要扩大现有的身体的数据映射和基因分型的古老的生长的立场，以获得性别聚集指数，并显示其有用性估计的克隆性与来自微卫星基因分型的克隆性指数进行比较。由于基因分型方法的改变（从AFLP到高通量微卫星多重PCR），我们节省了对另外三个株进行基因分型的资金。这将为一个博士提供消耗品。学生（目前由梅克伦堡-西波美拉尼亚州奖学金支付）完成博士学位。论文
