背景气候变化可能对野生动物种群中寄生虫的分布、丰度、传播和毒力产生重要影响。方法/主要发现在这里，我们分析了几年前和2010年的24种鸟类宿主的89个寄生虫种群的配对信息，平均间隔为10年。寄生虫类群包括原生动物、羽毛寄生虫、双翅目、蜱、螨和蚤。我们调查了寄生虫丰度和流行率的变化是否与宿主的身体状况、繁殖和种群大小的变化有关。我们基于整个数据集进行了分析，但也基于研究年间隔为5-15年的受限数据集进行了分析。当将分析限制在间隔5-15年的数据集时，寄生虫丰度随着时间的推移而增加，在研究地点之间繁殖时温度变化没有显着影响。宿主身体状况和窝卵数的变化与第一和第二研究年之间的温度变化有关。此外，窝卵数、育雏数和宿主身体状况的变化与寄生虫丰度的变化相关。最后，宿主种群规模的变化与寄生虫丰度或其流行率的变化没有显着相关。结论/意义气候变化与寄生虫丰度的普遍增加有关。产卵日期的变化取决于地点，并与纬度，而主机的身体状况与温度的变化。由于离合器大小，育雏大小和身体状况与寄生的变化，这些结果表明，寄生虫，可能介导的温度的间接影响，可能会影响其主机的繁殖力和条件。当使用间隔为5-15年的限制数据集时，结论特别符合预测，这表明短间隔可能会使结果产生偏差。
Background Climate change potentially has important effects on distribution, abundance, transmission and virulence of parasites in wild populations of animals. Methodology/Principal Finding Here we analyzed paired information on 89 parasite populations for 24 species of bird hosts some years ago and again in 2010 with an average interval of 10 years. The parasite taxa included protozoa, feather parasites, diptera, ticks, mites and fleas. We investigated whether change in abundance and prevalence of parasites was related to change in body condition, reproduction and population size of hosts. We conducted analyses based on the entire dataset, but also on a restricted dataset with intervals between study years being 5–15 years. Parasite abundance increased over time when restricting the analyses to datasets with an interval of 5–15 years, with no significant effect of changes in temperature at the time of breeding among study sites. Changes in host body condition and clutch size were related to change in temperature between first and second study year. In addition, changes in clutch size, brood size and body condition of hosts were correlated with change in abundance of parasites. Finally, changes in population size of hosts were not significantly related to changes in abundance of parasites or their prevalence. Conclusions/Significance Climate change is associated with a general increase in parasite abundance. Variation in laying date depended on locality and was associated with latitude while body condition of hosts was associated with a change in temperature. Because clutch size, brood size and body condition were associated with change in parasitism, these results suggest that parasites, perhaps mediated through the indirect effects of temperature, may affect fecundity and condition of their hosts. The conclusions were particularly in accordance with predictions when the restricted dataset with intervals of 5–15 years was used, suggesting that short intervals may bias findings.
