Fig. 4From: Long-term study reveals central European aerial insectivores as an unusual group of hosts that harbor mostly helminths that are unable to complete life-cycles in the nesting quarters of their hostsVolcano plot for Pearson correlations between the month when the bird host was acquired and the frequency of infections, the helminth load, and species-specific data on the abundance of individual helminth species. The color space indicates significant correlations (P < 0.05). Selected significant variables are labeled on plotsBack to article page
