A life between wild water and steep rock. Population-ecological examination at the yellow-bellied hamlet (Bombina variegata) in the Gesäuse National Park

From May to September 2016, a catch-re-catching study was carried out in the Gesäuse National Park on the yellow belly hamlet (Bombina variegata). The study area extends between 490 m and 2 369 m above sea level. During the four to six visits at the different sites, the animals were caught, photographed on the belly side, sex determined, biometric data measured and water parameters recorded. A sample of 13 animals was tested for the presence of chytrid fungi Batrachochytrium dendrobatidis (Bd). For comparative data, areas close to the National Park and the Kalkalpen National Park were investigated.2016年5月至9月，研究团队于格萨乌国家公园（Gesäuse National Park）针对黄腹铃蟾（Bombina variegata）开展了捕获重捕研究。该研究的样地海拔范围为490米至2369米。在针对不同样地进行的4至6次走访调查中，研究人员捕获受试个体，拍摄其腹部腹面图像，鉴定个体性别，测量生物特征参数，并记录水体理化参数。随后，研究人员对13个个体样本开展了蛙壶菌（Batrachochytrium dendrobatidis，简称Bd）的感染检测。为获取对比数据，研究团队同时对格萨乌国家公园周边区域以及卡尔卡彭国家公园（Kalkalpen National Park）开展了调查。
