Local environment and sampling bias drive parasite prevalence estimates in freshwater fish communities

open access: yesOikos, Volume 2025, Issue 7, July 2025.
Parasite occurrence and infection estimates vary through time and space, making understanding the underlying drivers highly complex. Comparative studies based on empirical data must consider the factors of variation involved in estimating infection metrics in natural populations to make appropriate and reliable comparisons. Using a multi‐scale approach,
