Occurrence of small mammals in Mordovia State Nature Reserve and National Park “Smolny” (European Russia)

Our dataset includes 7950 records of small mammals (Erinaceomorpha, Soricomorpha, Chiroptera and Rodentia) in Mordovia State Nature Reserve and National Park “Smolny” (European Russia). The data on 35 species of micromammals belonging to 4 orders, 21 genera and 9 families are presented. The dataset summarizes small mammals’ occurrences obtained by field studies in the territory of this protected area between 2018 to 2023. Each occurrence record contains the species name, basis of record, age and sex of studied animals, females’ reproductive conditions, geographic coordinates, coordinate accuracy, date of the record and authors of the record and species identification. All occurrence records are georeferenced. The dataset is based on research of the staff of the Institute of Ecology of the Volga River basin of the Russian Academy of Sciences and the Joint Directorate of the Mordovia State Nature Reserve and National Park “Smolny”. A major part of the data set was obtained during our helminthological study of micromammals. Another part of the data was obtained when studying ecology and abundance of chiropterans using mist nets. Our studies of rodents and insectivores were conducted by trap lines and direct observations in nature.

本数据集收录了位于莫尔多维亚国家自然保护区及国家公园‘斯莫尔尼’（欧洲俄罗斯）的7950条小型哺乳动物（刺猬目、食虫目、翼手目和啮齿目）的记录。数据集展示了隶属于4个目、21个属和9个科的35种小型哺乳动物的详细信息。该数据集汇总了2018年至2023年间在该保护区域进行的实地研究中获取的小型哺乳动物的分布情况。每条分布记录均包含物种名称、记录依据、研究动物的年龄和性别、雌性动物的繁殖状况、地理坐标、坐标精度、记录日期以及记录和物种鉴定者的信息。所有分布记录均已进行地理编码。本数据集基于俄罗斯科学院伏尔加河流域生态研究所及莫尔多维亚国家自然保护区和国家公园‘斯莫尔尼’联合管理处的科研人员的研究成果。数据集的大部分数据来源于我们对小型哺乳动物进行的寄生虫学调查研究。另一部分数据则是在使用迷网研究翼手目的生态学和丰富度时获得。我们对啮齿目和食虫目的研究则通过陷阱线和野外直接观察进行。
