项目摘要

The Mottled Duskywing (Erynnis martialis) is an endangered butterfly species in Canada. To reverse the contraction in its geographic range observed over the last several decades, recovery-planning documents suggest re-establishing the species at historical sites where suitable habitat remains and/or assisting colonization at previously unoccupied sites with suitable habitat. In 2015, Natural Resource Solutions Inc. (NRSI) began coordinating a multi-year collaborative project to work towards this goal by addressing key actions and knowledge gaps identified in the Draft Recovery Strategy for Mottled Duskywing. The proposed research will contribute to this multi-year collaborative recovery initiative by addressing key knowledge gaps relating to the genetics of the Mottled Duskywing. We will develop microsatellite genetic markers for Mottled Duskywing and complete genetic sampling throughout the species' range in Ontario and nearby locations in the US. This will provide information about the genetic diversity and differentiation of the Ontario subpopulations, effective population size (related to census population size), and, in conjunction with mark-recapture data being collected by collaborators, indirect estimates of gene flow. Given that genetic techniques are now widely used in conservation biology to identify source populations for reintroductions and to assess extinction risk (Frankham et al. 2002), the proposed research will directly inform Mottled Duskywing population augmentation and re-introduction efforts in Ontario.

斑驳的Duskywing（Erynnis martialis）是加拿大濒临灭绝的蝴蝶物种。为了扭转过去几十年来观察到的地理范围内的收缩，恢复计划的文件表明，在历史遗迹上重新建立该物种，在历史遗迹中保留合适的栖息地和/或协助在以前没有居住地的居住地，具有合适的栖息地。 2015年，自然资源解决方案有限公司（NRSI）开始协调一个多年的合作项目，通过解决莫特尔·多斯基温（Mottled Duskywing）恢复策略草案中确定的关键行动和知识差距，以实现这一目标。拟议的研究将通过解决与斑驳的Duskywing遗传学有关的关键知识差距，为这项多年的合作恢复计划做出贡献。我们将在安大略省和美国附近的整个物种范围内开发微卫星遗传标记，以用于斑驳的duskywing和完整的遗传抽样。这将提供有关安大略省亚群的遗传多样性和分化的信息，有效的人口规模（与人口普查人口规模相关）以及合作者共同收集的标记 - 重新获得数据的间接估计。鉴于遗传技术现已广泛用于保护生物学，以鉴定重新引入的来源人群并评估灭绝风险（Frankham等，2002），拟议的研究将直接为安大略省的斑驳的Duskywing人口增强和重新引入工作提供信息。
