Developing strategies for the protection of taxa consisting of interconnected sexual and parthenogenetic reproducing strains

科学：将建立一个模型，以了解从两性起源种群到单性生殖先驱种群的基因流动，从而分析这种网络对遗传漂变现象的抵抗力。这是第一次，相关的踏脚石栖息地可以进行分析，因为稀缺的潜在人口的原产地以及踏脚石栖息地，后者很容易被识别，其特有的特点（内陆咸水网站-稀缺，因为它们以前的重要性，作为一个盐的来源，有充分的记录）。此外，还将安装一个模型，以解开切换到单性生殖的触发器，从而进行基础分子生物学研究。社会/政策：通过了解两性种群的起源和他们的孤雌生殖的女儿种群之间的连接保持它们之间的基因流的重要性将被量化，因此，保护措施的效率提高，通过确定关键的踏脚石栖息地，或者，直接的措施，重新安装遗传交换。为保护区制定多用途管理计划，允许保护基本上不同的物种群体（在这种情况下是轮藻和鸟类），将提高保护区的接受程度和效率。关于本提案的目标物种，该项目将通过保护健康水生生态系统的关键要素（生境工程师）来促进欧盟水框架指令的要求，该要素已被证明能够稳定已经恶化的系统的良好环境状态。

Scientific: a model for understanding gene-flow from bisexual populations of origin to parthenogenic pioneer populations will be developed, allowing analysis of resistance of such networks against genetic drift phenomena. For the first time, the relevance of stepping-stone habitats can be analysed in total because of the scarcity of potential populations of origin as well as stepping-stone habitats, the latter ones easy to be recognized by their peculiar characteristics (inland brackish water sites – scarce and, because of their former importance as a source of salt well documented). In addition, a model for unravelling the trigger for switching to parthenogenesis will be installed, allowing for basic molecular biology research. Societal/policy: By understanding the connectivity between the bisexual populations of origin and their parthenogenetic daughter populations the importance of keeping gene-flow between them will be quantified and, consequently, efficiency of conservation measures improved by identifying crucial stepping-stone habitats or, alternatively, direct measures to re-install genetic exchange. Developing multi-purpose management schemes for protected areas, allowing for protection of largely different species groups (in this case charophytes and birds) will increase acceptance and efficiency of protected areas. With respect to the target species of this proposal, the project will contribute to the requirements of the EU-Water Framework Directive by protection of a crucial element (habitat engineer) of healthy aquatic ecosystems, shown to be able to stabilize good environmental status of already deteriorated systems.
