摘要
Small human-used root cellars are the most widespread bat hibernacula in Latvia, but their importance was hitherto underestimated. We compared bat species diversity and numbers of individuals in root cellars with that in other types of bat hibernacula in Latvia over 35 years. Both species diversity and number of bats hibernating in root cellars were significantly lower than that in other roost types. However, two species, Plecotus auritus and Eptesicus nilssonii, extensively used root cellars as hibernacula. The maximum population size of bat species hibernating in root cellars in Latvia was estimated to be from 27,600 to 42,450 individuals for P. auritus and from 7940 to 12,210 for E. nilssonii. We conclude that root cellars are crucial hibernation sites for P. auritus and E. nilssonii in Latvia.

人类使用的小型根窖是拉脱维亚最普遍的蝙蝠冬眠，但其重要性迄今为止被低估了。我们比较了窖藏物种多样性和根窖中个体数量与拉脱维亚其他类型蝙蝠冬眠的数量超过35年。在根窖冬眠的物种多样性和蝙蝠数量都显着低于其他栖息类型。然而，两种物种，Plecotus auritus和Eptesicus nilssonii，广泛使用根窖作为冬眠。拉脱维亚根窖冬眠蝙蝠物种的最大种群数量估计为P. auritus的27,600至42,450个体，以及E. nilssonii的7940至12,210个体。我们得出结论，根窖是拉脱维亚P. auritus和E. nilssonii的重要冬眠地点。
