Seasonal changes in infection status and parasitemia in juvenile house sparrows. Changes in infection status (% blood-positive individuals) and infection intensity (log10 parasitemia, box plot where the bottom and top of the box indicates the first and third quartiles, the central line corresponds to the median, the whiskers represent the highest and lowest value within 1.5 * the interquartile range respectively) for H. passeris (green bars) and P. relictum (blue bars) in juvenile house sparrows, from July 2016 until October 2016 (week 30–43). The number of studied individuals is rather constant over time (N = 11 in week 30 and N = 9 in week 43)
