Quantitative reconstructions of Holocene and Late Pleistocene palaeotemperatures in Yakutia, North-Eastern Russia using regional Chironnomid inference model

尽管俄罗斯北方地区对全球气候发展具有重要意义，但该地区定量古气候研究的实例很少。重建方法的主要缺点是缺乏区域校准数据集。任何应用非区域模型进行To重建都会造成数据解释的困难，并使结果存在争议和不相容。该项目的目标是：完成一个区域摇蚊推断的空气温度，水深，水传导率模型，并作出高分辨率重建全新世和晚更新世的古气候变化在雅库特中部，使用这些区域模型和先进的分析化石摇蚊动物从长沉积物芯（超过10万年BP）。该项目将导致：第一个基于俄罗斯摇蚊的区域校准数据集;第一个关于亚化石摇蚊的泛欧亚数据库;摇蚊平均7月气温，水深，电导率推断模型;第一次用区域模型估计该地区与气候相关的参数;对未来气候变化如何影响极端条件下的淡水生态系统的见解;关于这一研究不足地区摇蚊动物群的新生态数据;俄罗斯北方摇蚊的第一个分类数据库和基于网络的鉴定指南。拟议的工作是多代理研究的一部分。

In spite of a high importance of Northern Russia for global climate development there are only few examples of quantitative palaeoclimate studies in this region. The main drawback of the reconstruction approach is the lack of a regional calibration datasets. Any application of non-regional models for To reconstruction causes difficulty in data interpretation and makes results controversial and incompatible. The aims of the project are: To complete a regional chironomid-inferred air temperature, water depth, water conductivity models and to make, a high resolution reconstructions of Holocene and Late Pleistocene palaeoclimate variability in Central Yakutia, using these regional models and advanced analysis of the fossil chironomid fauna from long sediment cores (more than 10 ka BP). The project will lead to: first regional Russian chironomid-based calibration data set; first pan-Eurasian database on subfossil chironomids; chironomid mean July air temperature, water depth, conductivity inference models; the first estimates of climate-related parameters for this area made with regional models; insights into how future climate change might affect freshwater ecosystems in extreme conditions; new ecological data about chironomid faunas from this poorly-studied region; the first taxonomic database and web-based identification guide to chironomids from Northern Russia. The proposed work is a part of multi-proxy studies.
