用蝙蝠箱对瑞典最南端的两个种群管蝠进行了连续8个繁殖季节的研究。与居住在农村地区的人口相比，居住在工业区附近的人口有下降的趋势。当脂肪在冬眠前开始积累时，9月份的质量指数也低于农村地区的指数。居住在工业区附近的人口中，有机氯残留物和镉的水平也较高。然而，下降的最直接原因被认为是由于排水和水污染导致的饲养条件恶化。
Two populations of the pipistrelle batPipistrellus pipistrellusin southernmost Sweden were studied for eight consecutive breeding seasons using bat boxes. The population living in the vicinity of an industrial area had a declining population trend when compared to that form a rural area. Mass indices in September, when fat accumulation prior to hibernation has started, were also lower compared to those obtained in the rural area. The levels of organochlorine residues and of cadmium were also higher in the population living close to the industrial area. The proximate cause of the decline, however, is assumed to be deteriorating feeding conditions due to drainage and water pollution.
